5.1 Program Functions

If the battery voltage drops below the defined Battery Voltage Lower Limit (P04), an alarm occurs and “Low Battery Failure” LED illuminates.

P02 Speed Lower LimitP03 Speed Upper LimitP28 Speed Fault Control Delay

A fault will be reported if the alternator output frequency goes outside the window defined by the upper and lower limits for more than the time defined as the Alternator speed fault control delay (P28). The fault will only occur if the engine has started to run and has been running for the period defined as the Control on Delay (P26). This failure immediately stops the generating set without Engine Cooling Time (P29)

P00 Alternator Voltage Lower LimitP01 Alternator Voltage Upper LimitP27 Alternator Voltage Fault Control Delay

A fault will be reported if the alternator output voltage goes outside the window defined by the upper and lower limits for more than the time defined as the Alternator Voltage Fault Control Delay (P27). The fault will only occur if the engine has started to run and has been running for the period defined as the Control on Delay (P26). This failure immediately stops the generating set without Engine Cooling Time (P29)

5.1.1 Alternator Voltage

5.1.2 Alternator Frequency

5.1.3 Battery Voltage Lower Limit (P04)

P06 Periodic Maintenance Hour Set ValueP07 Periodic Maintenance Hour Reset

To ensure reliability, the engine must be serviced at regular intervals. The unit can be set to indicate when a service is due. Set Periodic Maintenance Hour Set Value (P06) to the number of running hours between services. Use Periodic Maintenace Hour Reset (P07) to reset the hours counter at each service. When the engine has run for the defined number of hours, the alarm LED will flash and when the alarm display option is selected, the display will show the error message bAEr.

5.1.4 Maintenance Indication

This parameter specifies the method to read generator frequency. The choice is between alternator frequency and external magnetic pick-up. Frequency and speed is monitored so as to detect when engine has started and if there is a generator frequency failure. See Sections 5.1.2 Alternator Frequency, 5.1.8 Engine started signals (P18) and 5.1.10 Engine Starting.Speed Limit for Crank Disconnection (P22) should be set to the frequency that must be achieved at start-up. When magnetic pick-up is using Tooth Number (P13) must be entered correctly. Nominal Alternator Frequency (P11) and Nominal Speed (P12) are used to compute alternator RPM or frequency. If Speed Sensing Input Selection (P15) ise set to 0 (from Alternator Voltage), the unit uses Nomainal Alternator Frequency (P11) and Nominal Speed (P12) to calculate RPM from the measured frequency of the alternator voltage. If Speed Sensing Input Selection (P15) is 1 (from Magnetic Pick-up), the unit uses Nominal Alternator Frequency (P11) and Nominal Speed (P12) to calculate alternator output frequency from the measured RPM.

5.1.5 Speed Sensing Input Selection (P15)

24

This parameter allows the use of either a Stop solenoid or a Fuel solenoid. (See Section 5.1.10 Engine Starting.)

If Fuel Solenoid selected, the fuel solenoid will be energised while the engine is running and de-energised to cut off the fuel and stop the engine. If Stop Solenoid selected, the stop solenoid is normally de-energised and only energised to stop the engine. The solenoid remains energised for the period defined as the Stop Magnet Energising Time (P17). See Section 5.1.10 Engine Starting.

This parameter sets the period for which the Stop solenoid is energised to stop the engine. It applies only where parameter Stop / Fuel Solenoid Selection (P16) is set to Stop Solenoid. See Section 5.1.6 Stop/Fuel Solenoid Selection (P16)

5.1.6 Stop / Fuel Solenoid Selection (P16)

5.1.7 Stop Magnet Energising Time (P17)

Battery Voltage Weak Limit (P19)Battery Voltage Weak Control Time (P20)

If the battery voltage drops below the level specified by the Battery Voltage Weak Limit (P19) for more than the Battery Voltage Weak Control Time (P20) during engine cranking an alarm occurs. The message Weak Battery is displayed on the LED display. Use the Reset Button to clear the alarm indication.

5.1.9 Battery Voltage

5.1.8 Engine Started Signals (P18)

25

The unit must de-energise the Start solenoid to disconnect the starter motor, once the engine is running. Conversely, if the engine does not start after the pre-set start time, the unit will turn off the starter motor and try again. Hence, the unit must be able to detect when the engine has started. Four signals are available to provide engine running information as follows :0. Charge generator (P18.0); f r o. m charging generator energising coil current. 1. Speed (P18.1); if engine speed is higher than Speed Limit for Crank Disconnection (P22), pay attention to the Speed Sensing Input Selection (P15) (Refer to 5.1.8)2. Alternator Voltage (P18.2); if alternator voltage is higher than Alternator Voltage Limit for Crank Disconneciton (P21)3. Oil pressure (P18.3); it looks if oil pressure switch is closed.Any or all of these signals can be selected for use. It is advisable to select at least two of them –preferably 1. Engine speed, 2. Charging generator or Alternator voltage.See Section 5.1.10 Engine Starting. If any of the selected signals appears, the unit assumes that the engine has started.

Number of Starting Attempts (P23)Starting Attempt Duration (P24)

After that the unit energises the start solenoid to drive the starter motor and energises the Fuel solenoid, the starting sequence commences. If the preheating output has been configured (see section 5.1.15 Configurable Outputs), the display will show the HEAT message for the time period set by Preheat Time (P09). After that the unit energises the start solenoid to drive the starter motor and energises the Fuel solenoid (if selected – see Section 5.1.6 Stop/Fuel Solenoid selection (P16)) to provide fuel for the engine. If the unit detects that the engine has started, it de-energises the starter motor. Engine start signals are defined by parameter P18 – see Section 5.1.8 Engine started signals (P18). Starting Attempt Duration (P24) defines the maximum period for which drive will be applied to the starter motor. If the unit does not detect engine starting within this period, it cuts off the drive to the starter motor and de-energises the fuel solenoid, if selected. It then makes a new attempt after a delay equal to twice the defined Starting Attempt Duration (P24). Number of Starting Attempts (P23) defines the number of unsuccessful tries that the unit will make before abandoning the attempts. If all these attempts fail, further operations are locked out and a Failed to Start indication is displayed. The unit remains locked until the reset button has been pressed.

5.1.10 Engine Starting

This sets the delay before a Low Oil Pressure warning will be generated. The Low Oil Pressure fault indicator will light if the oil pressure switch contact remains opened, while the engine is running, after the period defined by parameter. This period begins when the EAOM-6 has detected engine starting and has cut off the drive to the starter motor. This failure immediately stops the generating set without Engine Cooling Time (P29).

5.1.11 Oil Pressure By-Pass Time (P25)

During the initial period after the engine has been started, there can be fluctuations in engine speed and alternator output that could generate spurious fault indications. Control On Delay (P26) defines a period during which any fault indications, except High Temperature, will be ignored by the unit. This period begins when the EAOM-6 has detected engine starting and has cut off the drive to the starter motor.

5.1.12 Control On Delay (P26)

Engine Cooling Time (P29) defines the duration of the cooling-off period. When operating under heavy load, the engine can get very hot and is only prevented from overheating by circulating coolant. If the engine is stopped abruptly under these conditions, it can overheat as the coolant flow is cut off. Where the unit controls the load, via one of the configurable outputs, it can ensure that the engine continues to run after the load has been removed.

5.1.13 Engine Cooling Time (P29)

26

Configurable Failure Input-1 (P31)Configurable Failure Input-2 (P32)Configurable Failure Input-3 (P33)

A contact closure to 0V on any of these inputs causes the horn to sound for the period programmed by Horn Duration (P08) and lights the appropriate indicator on the panel. The unit can be programmed to respond in one of four ways:0. Indication is unlatched-the LED flashes and horn is sounding while the input is 0V. If the input is not 0V the led will cancel flashing and horn sound.1. Indication is latched when the input is 0V then, the led flashes and horn is sounding then stays on until the Reset button is pressed.2. This is the same as 1 but in addition the engine is stopped.3. Contactor releaser. It is valid only if the load transfer permit output is selected in configuration outputs 1 and 2.

5.1.14 Configurable Inputs

Configurable Output-1 (P35)Configurable Output-2 (P36)

When active, this output provides battery voltage (12VZ or 24VZ) and can be programmed in one of fourteen different ways:

0. Alarm output. Active when any fault is reported. It can be used for either audible or visual alert.1. Engine running. Active while the engine is running2. Load transfer permitted. This output is active while engine is start to run and Control on Delay (P26) expired and Alternator output voltage is between Alternator Voltage Upper Limit (P00) and Alternator Voltage Lower Limit (P01). This output can be used to control a contactor that transfers the load to the alternator once the generator set is up and running.3. Preheat function. On starting the output is active for time period defined in Preheat Time (P09) prior to running the starter motor.4. Over speed5. High temperature6. Low oil pressure7.8.9.10.11.12.13.

Alternator output voltage and frequencyEngine RPMBattery voltageElapsed timeBattery chargingLoad current (1 phase)Temperature, pressure and fuel level from resistive sendersEngine running timeEngine PowerError indicationProgram parameters

The unit is extensively programmable with password protection on two levels. In the event that the engine fails to start on the first attempt, the attempt will be repeated a programmed number of times or until successful.If a fault is detected, the unit shuts down the engine and indicates the failure by flashing an appropriate fault LED.Remote fuel, start and emergency stop inputs provide for remote control of the engine.

Three user-defined inputs are included that sound an external horn, flash indicators on the panel and can be programmed to stop the engine.Two extra outputs can be configured to act on an alarm, when the engine is running, when a load can be transferred to the alternator or when engine preheating is required. The operational parameters of the unit can be monitored and controlled from a PC via a built-in RS-232 port.

A fault will be reported if the alternator output frequency goes outside the window defined by the upper and lower limits for more than the time defined as the Alternator Speed Fault Control Delay (P28). The fault will only occur after the engine has been running for the period defined as the Control on Delay (P26). This failure immediately stops the generating set without Engine Cooling Time (P29)


A fault will be reported if the alternator output voltage goes outside the window defined by the upper and lower limits for more than the time defined as the Alternator Voltage Fault Control Delay (P27). The fault will only occur if the engine has been running for the period defined as the Control on Delay (P26). This failure immediately stops the generating set without Engine Cooling Time (P29)





To ensure reliability, the engine must be serviced at regular intervals. The unit can be set to indicate when a service is due. Set Periodic Maintenance Hour Set Value (P06) to the number of running hours between services. Use Periodic Maintenace Hour Reset (P07) to reset the hours counter at each service. When the engine has run for the defined number of hours, the alarm LED will flash and when the alarm display option is selected, the display will read the error message bAEr.


This parameter specifies the method to read generator frequency. The choice is between alternator frequency and external magnetic pick-up. Frequency and speed is monitored so as to detect when engine has started and if there is a generator frequency failure. See Sections 5.1.2 Alternator Frequency, 5.1.9 Engine started signals (P18) and 5.1.12 Engine Starting. Speed Limit For Crank Disconnection (P22) should be set to the frequency that must be achieved at start-up. When magnetic pick-up is using Tooth Number (P13) must be entered correctly. Nominal Alternator Frequency (P11) and Nominal Speed (P12) are used to compute alternator RPM or frequency. If Speed Sensing Input Selection (P15) is set to 0 (from Alternator Voltage), the unit


An alarm occurs if the load current exceeds the load current limit for more than 5 seconds after the period defined by the Control on Delay (P26). The message ocr (Over Current) appears on the display.

5.1.4 Over Current Limit (P05)

If Fuel Solenoid selected, the fuel solenoid will be energised while the engine is running and de-energised to cut off the fuel and stop the engine. If Stop Solenoid selected, the stop solenoid is normally de-energised and only energised to stop the engine. The solenoid remains energised for the period defined as the Stop Magnet Energising Time (P17). See Section 5.1.12 Engine Starting.







The unit must de-energise the Start solenoid to disconnect the starter motor, once the engine is running. Conversely, if the engine does not start after the pre-set start time, the unit will turn off the starter motor and try again. Hence, the unit must be able to detect when the engine has started. Four signals are available to provide engine running information as follows :

1. Engine speed, as selected by Speed Sensing Input Selection (P15) and Speed Limit for Crank Disconnection (P22) (Section 5.1.6 Speed Sensing Input Selection (P15))2. Alternator voltage as selected by parameters Alternator Voltage Limit for Crank Disconnection (P21)

Any or all of these signals can be selected for use. It is advisable to select at least two of them –preferably 1. Engine speed, 2. Charging generator or Alternator voltage.See Section 5.1.12 Engine Starting. If any of the selected signals appears, the unit assumes that the engine has started.

0. Charge Generator (P24.0 ); from charging generator energising coil current.

3. Oil pressure; it looks if oil pressure switch is closed.


uses Nominal Alternator Frequency (P11) and Nominal Speed (P12) to calculate RPM from the measured frequency of the alternator voltage. If Speed Sensing Input Selection is 1 (from Magnetic pick-up), the unit uses Nominal Alternator Frequency (P11) and Nominal Speed (P12) to calculate alternator output frequency from the measured RPM.

27

The current transformer input / output ratio can be entered into this parameter, allowing the primary current value to be displayed.

5.1.11 Current Transformer Ratio (P14)


When the unit receives an Engine Start command from the front panel or via the remote start input, the starting sequence commences. If the preheating output has been configured (see section 5.1.17 Configurable Outputs), the display will show the HEAT message for the time period set by Preheat Time (P09). The unit energises the start solenoid to drive the starter motor and energises the Fuel solenoid (if selected – see Section 5.1.7 Stop/Fuel Solenoid selection (P16)) to provide fuel for the engine. If the unit detects that the engine has started, it de-energises the starter motor. Engine start signals are defined by parameter P18 – see Section 5.1.9 Engine started signals (P18). Starting Attempt Duration (P24) defines the maximum period for which drive will be applied to the starter motor. If the unit does not detect engine starting within this period, it cuts off the drive to the starter motor and de-energises the fuel solenoid, if selected. It then makes a new attempt after a delay equal to twice the defined Starting Attempt Duration (P24). Number of Starting Attempts (P23) defines the number of unsuccessful tries that the unit will make before abandoning the attempts. If all these attempts fail, further operations are locked out and a Failed to Start indication is displayed. The unit remains locked until the reset button has been pressed.


This sets the delay before a Low Oil Pressure warning will be generated. The Low Oil Pressure fault indicator will light if the oil pressure switch contact remains closed, while the engine is running, after the period defined by parameter. This period begins when the EAOM-71 has detected engine starting and has cut off the drive to the starter motor. This failure immediately stops the generating set without Engine Cooling Time (P29).






28


A contact closure to 0V on any of these inputs causes the horn to sound for the period programmed by Horn Duration (P08) and lights the appropriate indicator on the panel. The unit can be programmed to respond in one of three ways:0. Indication is unlatched - the LED flashes only while the input is 0V. This indication is inhibited if any other alarm condition is present.1. Indication is latched. The LED flashes while the horn is sounding and then stays on until the Reset Button is pressed.2. This is the same as 1 but in addition the engine is stopped.



When active, this output provides battery voltage (12VZ or 24VZ) and can be programmed in one of sixteen different ways:

0. Alarm output. Active when any fault is reported. It can be used for either audible or visual alert.1. Engine running. Active while the engine is running2. Load transfer permitted. This output is active while the alternator output voltage is between Alternator Voltage Lower Limit (P00) and Alternator Voltage Upper Limit (P01). This output can be used to control a contactor that transfers the load to the alternator once the generator set is up and running.3. Preheat function. On starting the output is active for time period defined in Preheat Time (P09) prior to running the starter motor.4. Over Speed5. Over Current6. Low Fuel Level7. High Temperature8. Low Oil Pressure9. Maintenance Due10. Failed to Start11. Over / Under Speed12. Voltage Failure13. Charging Failure14. Low Battery Voltage15. Weak Battery


29

The minimum oil pressure value, in “bar” units, can be entered into this parameter.

5.1.18 Pressure Lower Limit (P37)

This parameter defines the function of an alarm when the measured oil pressure value is lower than the value of Pressure Lower Limit (P37). If the parameter value is “0” then analogue pressure input is disabled. If the parameter value is “1” then it activates pre-alarm (warning). If the parameter value is “2” then it activates the shutdown alarm.

5.1.19 Pressure Configuration (P38)

The maximum temperature value, in “°C” units, can be entered into this parameter.

5.1.20 Temperature Upper Limit (P39)

This parameter defines the function of an alarm when the measured temperature value is higher than the value of Temperature Upper Limit (P39). If the parameter value is “0” then analogue pressure input is disabled. If the parameter value is “1” then it activates pre-alarm (warning). If the parameter value is “2” then it activates the shutdown alarm.

5.1.21 Temperature Configuration (P40)

The minimum fuel tank level value, in “%” units, can be entered into this parameter.

5.1.22 Level Lower Limit (P41)

This parameter defines the function of an alarm when the measured fuel tank level value is lower than the value of Level Lower Limit (P41). If the parameter value is “0” then analogue pressure input is disabled. If the parameter value is “1” then it activates pre-alarm (warning). If the parameter value is “2” then it activates the shutdown alarm.

Warning: Beware of the high voltages connected to this unit.Indicators on the central section of the panel will flash if a fault is detected. If a fault is indicated, proceed as follows:1. Find and fix the fault.2. Press the Reset button to enable a restart.3. Press the Engine Start buttonIn addition to the indicators on the centre panel, the Alarm LED will flash in the event of a fault. To discover the fault being reported by the Alarm LED, press repeatedly until the Alarm option has been selected. The display will indicate the fault condition, as follows:




This LED flashes and the horn sounds if the output from the battery charge generator fails after the engine has started. The fault will not be indicated if it occurs within the period defined by the Control On Delay (P26) after the engine has started. This failure will not shut down the engine.

This LED flashes if the alternator speed goes outside the values defined by the Speed Lower Limit (P02) and Speed Higher Limit (P03) parameters. For a fault to be indicated, the speed must be outside these limits for longer than the period defined by the Speed Fault Control Delay parameter (P28). Alternator speed is measured either by measuring alternator output frequency or by monitoring an external magnetic pick-up as selected by program parameter Speed Sensing Input Selection (P15). This failure immediately stops the generating set without Engine Cooling Time (P29).

9. FAULT FINDING







This LED flashes if the generator output fails to reach the values specified by the Alternator Voltage Lower Limit parameter (P00) within the period defined by the Control on Delay parameter P26. This failure immediately stops the generating set without Engine Cooling Time (P29).

This message appears if, during engine cranking, the battery voltage drops below the value specified by the Battery Voltage Weak Limit (P19) for longer than the period specified by the Battery Voltage Weak Control Time (P20). The message is reset by Reset Button.


The interval (hours run) between routine maintenance, set by program parameter Periodic Maintenance Hour Set Value (P06), has expired. On completion of the required engine maintenance, reset the maintenance timer using Periodic Maintenance Hour Reset ( P07).


This message will appear on the display if the alternator current exceeds the value programmed into the Over Current Limit (P05) for more than 5 seconds after the period defined by the Control On Delay (P26) parameter.This fault de-activates the configurable outputs P35.2 and P36.2 (Load Transfer Permit). Thus removing any alternator load controlled by these outputs. The engine will continue to run.

9.1.12 Over Current (ocr)

Isolate the equipment from the electricity supply during mechanical and electrical maintenance. When this is not possible, the equipment must be in the “STOP” position.c

P04 Battery Voltage Lower LimitP05 Battery Voltage Upper Limit

If the battery voltage drops below the defined Battery Voltage Lower Limit, an alarm occurs. The message bAT1 (Low battery) appears on the display. Similarly, if the battery voltage exceeds the defined Battery Voltage Upper Limit (P05), an alarm occurs. The message bAT3 (High Battery) appears on the display.


A fault will be reported if the alternator output frequency goes outside the window defined by the upper and lower limits for more than the time defined as the Speed Fault Control Delay (P33). The fault will only occur after the engine has been running for the period defined as the Control on Delay (P31). This failure immediately stops the generating set without Engine Cooling Time (P34)

A fault will be reported if the alternator output voltage goes outside the window defined by the upper and lower limits for more than the time defined as the Alternator voltage fault control delay (P32). The fault will only occur after the engine has been running for the period defined as the Control on Delay (P31). This failure immediately stops the generating set, without Engine Cooling Time (P34). There are four possible system types:P11= 1 Single phase system. Set parameters Alternator Voltage Lower Limit (P00) and

two phases. Parameters Alternator Voltage Lower Limit (P00) and Alternator Voltage Upper Limit (P01) are line to line voltage





To ensure reliability, the engine must be serviced at regular intervals. The unit can be set to indicate when a service is due. Set Periodic Maintenance Hour Set Value (P07) to the number of running hours between services. Use Periodic Maintenace Hour Reset (P08) to reset the hours




28

When the Remote Start/Stop Input is activated (starting), the engine will start after the Remote Start Time Delay (P19) period, in order to prevent unnecessary starting due to a fluctuating mains supply. The delay can be adjusted within a range 0-60 seconds.

5.1.6 Remote Start Time Delay (P19)

When the Remote Start/Stop Input is de-activated (stopping), the engine will stop after the Remote Stop Time Delay (P20) period in order to ensure that the mains supply has stabilised before transferring the load back to mains. The delay can be adjusted within a range 0-60 seconds

5.1.7 Remote Stop Time Delay (P20)

The Warm-Up delay timer starts when the engine is up and running. This delays loading of the generator until it has stabilised. Once the time delay has expired, the load transfer command can be issued via one of the configurable relay outputs 1-2 (P40-P41) if configured for this function.

5.1.8 Warm-Up Time Delay (P29)

When “Fast-Loading” is enabled (P30=1) the Control On Delay (P31) timer can be terminated once all of the monitored parameters have reached their normal settings. This allows the engine protection features to come on-line much faster than waiting for the Control-On Delay (P31) timer to elapse.

5.1.9 Control on Delay / Fast-Loading Selection (P30)

P13 Nominal Speed (RPM)P14 Tooth NumberP16 Speed Sensing Input SelectionP25 Speed Limit for Crank Disconnection

This parameter specifies the method to read generator frequency. The choice is between alternator frequency and external magnetic pick-up. Frequency and speed is monitored so as to detect when engine has started and if there is a generator frequency failure. See Sections 5.1.2 Alternator Frequency, 5.1.13 Engine started signals (P18) and 5.1.14 Engine Starting. Speed Limit For Crank Disconnection (P25) should be set to the frequency that must be achieved at start-up. When magnetic pick-up is using Tooth Number (P14) must be entered correctly. Nominal Alternator Frequency (P12) and Nominal Speed (P13) are used to compute alternator RPM or frequency. If Speed Sensing Input Selection (P16) is set to 0 (from Alternator Voltage), the unit uses Nominal Alternator Frequency (P12) and Nominal Speed (P13) to calculate RPM from the measured frequency of the alternator voltage. If Speed Sensing Input Selection is 1 (from Magnetic pick-up), the unit uses Nominal Alternator Frequency (P12) and Nominal Speed (P13) to calculate alternator output frequency from the measured RPM.

5.1.10 Speed Sensing

This parameter allows the use of either a Stop solenoid or a Fuel solenoid. With Fuel Solenoid selected, the fuel solenoid will be energised while the engine is required and de-energised to cut off the fuel and stop the engine. With Stop Solenoid selected, the stop solenoid is normally de-energised and only energised to stop the engine. The stop solenoid remains energised for the period defined as the Stop Magnet Energising Time (P18)


29

counter at each service. When the engine has run for the defined number of hours, the alarm LED will flash and when the alarm display option is selected, the display will read the error message bAEr. Setting Periodic Maintenance Hour Reset (P08) to zero will disable this feature.

The unit must de-energise the Start solenoid to disconnect the starter motor, once the engine is running. Conversely, if the engine does not start after the pre-set start time, the unit will turn off the starter motor and try again. Hence, the unit must be able to detect when the engine has started. Four signals are available to provide engine running information as follows :0. Charging generator output.1. Engine speed, as selected by Speed Sensing Input Selection (P16) and Speed Limit for Crank Disconnection (P25) (Section 5.1.10 Speed Sensing)2. Alternator voltage as selected by parameters Alternator Voltage Limit for Crank Disconnection (P24)

Any or all of these signals can be selected for use. It is advisable to select at least two of them –preferably 1. Engine speed, 2. Charging generator or Alternator voltage.See Section 5.1.14 Engine Starting. If any of the selected signals appears, the unit assumes that the engine has started.

3. Oil pressure; it looks if oil pressure switch is closed.

When the unit receives an Engine Start command from the front panel or via the remote start input, the starting sequence commences. If the preheating output has been configured (see section 5.1.21 Configurable Outputs), the display will show the HEAT message for the time period set by Preheat Time (P10). The unit energises the start solenoid to drive the starter motor and energises the Fuel solenoid (if selected – see Section 5.1.11 Stop/Fuel Solenoid selection (P17)) to provide fuel for the engine. If the unit detects that the engine has started, it de-energises the starter motor. Engine start signals are defined by parameter see Section 5.1.13 Engine started signals (P21). Starting Attempt Duration (P27) defines the maximum period for which drive will be applied to the starter motor. If the unit does not detect engine starting within this period, it cuts off the drive to the starter motor. It then makes a new attempt after a delay equal to twice the defined Starting Attempt Duration (P27). Number of Starting Attempts (P26) defines the number of unsuccessful tries that the unit will make before abandoning the attempts. If all these attempts fail, further operations are locked out and a Failed to Start indication is displayed. The unit remains locked until the reset button has been pressed.


This sets the delay before a Low Oil Pressure warning will be generated. The Low Oil Pressure fault indicator will light if the oil pressure switch contact remains opened, while the engine is running, after the period defined by parameter. This bypass time is also used for the analogue Oil Pressure Lower Limit (P43) if enabled and Pressure Configuration (P44) is set to shut down the engine

5.1.15 Oil Pressure Bypass Time (P28)



During the initial period after the engine has been started, there can be fluctuations in engine speed and alternator output that could generate spurious fault indications. Control On Delay (P31) defines a period during which any fault indications, except High Temperature, will be ignored by the unit. This period begins when the EAOM-72F has detected engine starting and has cut off the drive to the starter motor.




This timer is only operative when one of the configurable relay outputs is programmed to perform the pre-heat/post-heat function. When starting the generator, this output is active for time period defined in the Pre-Heat/Post-Heat time (P10) prior to running starter motor, and remains active during cranking and after the engine has started. If the engine fails to start, the pre-heating/post-heating output remains switched on during repeated starting attempts.

5.1.18 Preheat Time (P10)

The current transformer input / output ratio can be entered into parameter Current Transformer Ratio (P15), allowing the primary current value to be displayed. Example If the CT is 50:5A, set Current Transforer Ratio (P15) to 10.

5.1.19 Current Transformer Ratio (P15)

Connecting any of these inputs to 0V can activate the LED annunciator and/or alarm horn. The product can be programmed to respond in one of four ways: 0. Status – The LED lights only while the input is 0V. 1. Fire Switch Mode – When selected, the engine will keep running even if a shutdown signal or alarm is detected.2. Only Horn Temporary – The LED lights and the alarm horn sounds while the input is at 0V.3. Only Horn Permanent - The LED flashes while the horn is sounding and then stays on until the reset button is pressed.4. Engine Stop - the same as 2 but, in addition, the engine is stopped.



These outputs can be programmed to operate in the following ways:0. Alarm output. Active when any fault is reported. Can be used for either audible or visual alert1. Engine running. Active while the engine is running.2. Load transfer permitted. The output is active while the alternator output voltage is between the Alternator Voltage Lower Limit (P00) and Alternator Voltage Upper Limit (P01). This output can be used to control a contactor that transfers the load to the alternator once the generator set is up and running.

3. Preheat function. On starting the generator, this output is active for time period defined in Preheat Time (P10) prior to running the starter motor.4. Over Speed Shut-down Output. The fault will only occur after the engine has been running for the period defined in Speed Fault Control Delay (P33) and Speed Upper Limit (P03). This failure immediately stops the generating set, without Engine Cooling Time (P34) and activates this output.5. Over Current Alarm output. Active when an over current fault is reported.6. Low Fuel Level Alarm output. Active when a low fuel level fault is reported.7. High Temperature Alarm output. Active when a high temperature fault is reported.8. Low Oil Pressure Alarm output. Active when a low oil pressure fault is reported.9. Maintenance Due Alarm output. Active when the maintenance due alarm (service) is reported10. Failed To Start Alarm output. Active when failed to start fault is reported.11. Over/Under Speed Alarm output. Active when over or under speed fault is reported.12. Voltage Failure Alarm output. Active when an alternator voltage fault is reported.13. Charging Failure Alarm output. Active when a charging fail fault is reported.14. Low Battery Voltage Alarm output. Active when the low battery voltage fault is reported15. High Battery Voltage Alarm output. Active when the high battery voltage fault is reported16. Weak Battery Alarm output. Active when the weak battery fault is reported.

The product can determine engine oil pressure status from one of two sources. An oil pressure switch or an analogue pressure sender can be selected by parameter Oil Pressure Switch / Sender Selection (P42) as the source of the oil pressure signal. The sender limit Pressure Lower Limit (P43) is used as the starting signal and to shut down the engine if the analogue sender is selected. The Oil pressure Bypass Time (P28) will operate for both selections.

Warning: Beware of the high voltages connected to this unit.Indicators on the central section of the panel will flash if a fault is detected. If a fault is indicated, proceed as follows:1. Find and fix the fault.2. Press the Reset button to enable a restart.3. Press the Engine Start buttonIn addition to the indicators on the centre panel, the Alarm LED will flash in the event of a fault. To discover the fault being reported by the Alarm LED, press repeatedly until the Alarm option has been selected. The display will indicate the fault condition, as follows:


This LED flashes if the thermostatic switch on the engine indicates high temperature. If this fault occurs, the EAOM-72F will stop the engine without any Engine Cooling Time (P34).

This LED flashes if the Oil Pressure Switch on the engine indicates low oil pressure while the engine is running. To obtain this indication, the engine must have been running for at least the period specified by the Oil Pressure Bypass Time (P28). If this fault occurs, the EAOM-72F will stop the engine without any Engine Cooling Period (P34).

This LED flashes and the horn sounds if the output from the battery charge generator fails after the engine has started. The fault will not be indicated if it occurs within the period defined by the Control On Delay (P31) after the engine has started. This failure will not shut down the engine.

This LED flashes if the alternator speed goes outside the values defined by the Speed Lower Limit (P02) and Speed Higher Limit (P03) parameters. For a fault to be indicated, the speed must be outside these limits for longer than the period defined by the Speed Fault Control Delay parameter (P33). Alternator speed is measured either by measuring alternator output frequency or by monitoring an external magnetic pick-up as selected by program parameter Speed Sensing Input Selection (P16). This failure immediately stops the generating set without Engine Cooling Time (P34).

9. FAULT FINDING






9.1.5 Over Speed LED

This LED flashes if the alternator output fails to reach the value specified by the Alternator Voltage Lower Limit parameter (P00) within the period defined by the Control on Delay parameter (P31). This failure immediately stops the generating set without Engine Cooling Time (P34).


Spare inputs 1, 2 and 3. These inputs function as per the programming of parameters Configurable Failure Input-1, 2, 3 (P36, P37, P38). The LEDs will indicate the status of the input lines and the course of action is determined by the programming.

Error indicationProgram parameters

The unit is extensively programmable with password protection on two levels. In the event that the engine fails to start on the first attempt, the attempt will be repeated a programmed number of times or until successful.If a fault is detected, the unit shuts down the engine and indicates the failure by flashing an appropriate fault LED.Remote start and emergency stop inputs provide for remote control of the engine. Three user-defined inputs are included that sound an external horn, flash indicators on the panel and can be programmed to stop the engine.Two extra outputs can be configured to act on an alarm, when the engine is running, when a load can be transferred to the alternator or when engine preheating is required. The operational parameters of the unit can be monitored and controlled from a PC via a built-in RS-232 port, using PC based software.

A fault will be reported if the alternator output frequency goes outside the window defined by the upper and lower limits for more than the time defined as the Speed Fault Control Delay (P29). The fault will only occur if the engine has started to run and has been running for the period defined as the Control on Delay (P26). This failure immediately stops the generating set without Engine Cooling Time (P30)


A fault will be reported if the alternator output voltage goes outside the window defined by the upper and lower limits for more than the time defined as the Alternator Voltage Fault Control Delay (P28). The fault will only occur if the engine has started to run and has been running for the period defined as the Control on Delay (P26). This failure immediately stops the generating set without Engine Cooling Time (P30)





To ensure reliability, the engine must be serviced at regular intervals. The unit can be set to indicate when a service is due. Set Periodic Maintenance Hour Set Value (P06) to the number of running hours between services. Use Periodic Maintenace Hour Reset (P07) to reset the hours counter at each service. When the engine has run for the defined number of hours, the alarm LED will flash and when the alarm display option is selected, the display will show the error message bAEr.


This parameter specifies the method to read generator frequency. The choice is between alternator frequency and external magnetic pick-up. Frequency and speed is monitored so as to detect when engine has started and if there is a generator frequency failure. See Sections 5.1.2 Alternator Frequency, 5.1.9 Engine started signals (P18) and 5.1.11 Engine Starting. Speed Limit For Crank Disconnection (P22) should be set to the frequency that must be achieved at start-up. When magnetic pick-up is using Tooth Number (P13) must be entered correctly. Nominal Alternator Frequency (P11) and Nominal Speed (P12) are used to compute alternator RPM or frequency. If Speed Sensing Input Selection (P15) is set to 0 (from Alternator Voltage), the unit




24


If Fuel Solenoid is selected, the fuel solenoid will be energised while the engine is running and de-energised to cut off the fuel and stop the engine. If Stop Solenoid is selected, the stop solenoid is normally de-energised and only energised to stop the engine. The solenoid remains energised for the period defined as the Stop Magnet Energising Time (P17). See Section 5.1.11 Engine Starting.







The unit must de-energise the Start solenoid to disconnect the starter motor, once the engine is running. Conversely, if the engine does not start after the pre-set start time, the unit will turn off the starter motor and try again. Hence, the unit must be able to detect when the engine has started. Four signals are available to provide engine running information as follows :0. Charge generator (P18.0); f r o. m charging generator energising coil current. 1. Speed (P18.1); if engine speed is higher than Speed Limit for Crank Disconnection (P22), pay attention to the Speed Sensing Input Selection (P15) (Refer to 5.1.6)2. Alternator Voltage (P18.2); if alternator voltage is higher than Alternator Voltage Limit for Crank Disconneciton (P21)3. Oil pressure (P18.3); it looks if oil pressure switch is closed.Any or all of these signals can be selected for use. It is advisable to select at least two of them –preferably 1. Engine speed, 2. Charging generator or Alternator voltage.See Section 5.1.11 Engine Starting. If any of the selected signals appears, the unit assumes that the engine has started.


uses Nominal Alternator Frequency (P11) and Nominal Speed (P12) to calculate RPM from the measured frequency of the alternator voltage. If Speed Sensing Input Selection is 1 (from Magnetic pick-up), the unit uses Nominal Alternator Frequency (P11) and Nominal Speed (P12) to calculate alternator output frequency from the measured RPM.

25


When the unit receives an Engine Start command from the front panel or via the remote start input, the starting sequence commences. If the preheating output has been configured (see Section 5.1.16 Configurable outputs), the display will show the HEAT message for the time period set by Preheat Time (P09). After that the unit energises the start solenoid to drive the starter motor and energises the Fuel solenoid (if selected – see Section 5.1.7 Stop/Fuel Solenoid selection (P16)) to provide fuel for the engine. If the unit detects that the engine has started, it de-energises the starter motor. Engine start signals are defined by parameter P18 – see Section 5.1.9 Engine started signals (P18). Starting Attempt Duration (P24) defines the maximum period for which drive will be applied to the starter motor. If the unit does not detect engine starting within this period, it cuts off the drive to the starter motor and de-energises the fuel solenoid, if selected. It then makes a new attempt after a delay equal to twice the defined Starting Attempt Duration (P24). Number of Starting Attempts (P23) defines the number of unsuccessful tries that the unit will make before abandoning the attempts. If all these attempts fail, further operations are locked out and a Failed to Start indication is displayed. The unit remains locked until the reset button has been pressed.


This sets the delay before a Low Oil Pressure warning will be generated. The Low Oil Pressure fault indicator will light if the oil pressure switch contact remains opened, while the engine is running, after the period defined by parameter. This period begins when the EAOM-7 has detected engine starting and has cut off the drive to the starter motor. This failure immediately stops the generating set, without Engine Cooling Time (P30).






26


A contact closure to 0V on any of these inputs causes the horn to sound for the period programmed by Horn Duration (P08) and lights the appropriate indicator on the panel. The unit can be programmed to respond in one of three ways:0. Indication is unlatched - the LED flashes and horn is sounding while the input is 0V. If the input is not 0V the led will cancel flashing and horn sound.1. Indication is latched. When the input is 0V then the LED flashes and horn is sounding then stays on until the Reset button is pressed.2. This is the same as 1 but in addition the engine is stopped.



When active, this output provides battery voltage (12 VZ or 24 VZ) and can be programmed in one of fourteen different ways:

0. Alarm output. Active when any fault is reported. It can be used for either audible or visual alert.1. Engine running. Active while the engine is running2. Load transfer permitted. This output is active while engine starts to run and Control on Delay (P26) is expired and alternator output voltage is between Alternator Voltage Lower Limit (P00) and Alternator Voltage Upper Limit (P01). This output can be used to control a contactor that transfers the load to the alternator once the generator set is up and running.3. Preheat function. On starting the output is active for time period defined in Preheat Time (P09) prior to running the starter motor.4. Over Speed5. Over Current6. High Temperature7. Low Oil Pressure8.

This LED flashes and the horn sounds if the output from the battery Charge generator fails after the engine has started. The fault will not be indicated if it occurs within the period defined by the Control On Delay (P26) after the engine has started. This failure will not shut down the engine.

This LED flashes if the alternator speed goes outside the values defined by the Speed Lower Limit (P02) and Speed Upper Limit (P03) parameters. For a fault to be indicated, the speed must be outside these limits for longer than the period defined by the Speed Fault Control Delay parameter (P29). Alternator speed is measured either by measuring alternator output frequency or by monitoring an external magnetic pick-up as selected by program parameter P15. This failure immediately stops the generating set without Engine Cooling Time (P30).

9. FAULT FINDING







This LED flashes if the generator output fails to reach the values specified by the Alternator Voltage Lower Limit parameter (P00) within the period defined by the Control on Delay (P26) parameter. This failure immediately stops the generating set without Engine Cooling Time (P30).

To discover the fault being reported by the Alarm LED, press repeatedly until the Alarm option has been selected. The display will indicate the fault condition, as follows:








This message will appear on the display if the alternator current exceeds the value programmed into the Over Current Limit (P05) for more than 5 seconds after the period defined by the Control On Delay (P26) parameter.This fault de-activates the configurable outputs P36.2 and P37.2 (Load Permit). Thus removing any alternator load controlled by these outputs. The engine will continue to run.


Isolate the equipment from the electricity supply during mechanical and electrical maintenance. When this is not possible, the equipment must be in the “STOP” position. c

Symptom

Check all the wiring of the unit.

Possible Remedy

Check the Z supply. (measure voltage between pins 7 and 8)

Check the Z fuse.












When the battery voltage falls below the value specified by the Battery Voltage Lower Limit (P04). The EAOM-7 measures battery voltage at the EAOM-7 terminals. This failure is indicated with an error messages in EAOM-7. When this failure occurs in EAOM-7, the led with exclamation mark starts to flash and user can see the error messages with the Scroll button .
