4. OPERATING

The equipment is connected to asupervisor PC throw a serial line (RS232or RS485) and use the MODBUS protocol.

The WINWINWINWINHPRHPRHPRHPR software (working under

Windows

98, Windows

2000) allows theoperating parameters configuration andthe pressure setting definition.

The equipment is powered by a 230V or115V (50/60Hz) single phase powersupply and by a 10 to 36Vcc isolatedcontinuous power supply.

A pressure sensor mounted on the railgives the feedback signal for the regulation

loop.

One (or more) electro-mechanical actuatorallows the high-pressure regulation.

The command is adapted for each systemtype depending upon :

the number and the functioningprinciple of the actuators

the signals from the pump

6. STARTING OPERATION

The next connections need to be donebefore starting regulation.

For the description of each connector,

refer to the chapter Equipment

description .

1. Connect the power supply220VAC/50HZ on connector X1.

2. Install the Ground cable on X2.

3. Connect the battery supply on X3(except if the option HPR2-ALIM isinstalled)

4. Connect the actuators on theconnectors (X4, X5, X6 or X7)

5. Connect the pressure sensor (X10connector) Be aware to don't

connect the X10-5 to groundbecause a shunt is connectedbetween X10.5 and ground tomeasure the supplying current ofthe sensor.If this current is not between 4mAand 50mA, a "pressure sensorfault" will be generated.

The user, with the WINWINWINWINHPRHPRHPRHPRsoftware, needs to define if thepressure sensor delivers a voltageor a current and also to give thesensor curve (voltage in function ofpressure)

6. If your system needssynchronisation with the pumprotation, the SYNCHRO signal(X13) and the 3600/REV (X14)need to be connected.

It is not necessary to connect these

cables if you are using the EFS

1522 cards type 3 or 7 (number

written on the front end of the card)

7. Connect the RS485 cable (X18) orRS232 cable (X19) between theelectronic rack and the control PC.(You need to install and run theWINWINWINWINHPRHPRHPRHPRsoftware on the PC).

8. It is possible but not necessary toconnect the logical inputs/outputs(connector X8 and X9) to a PLC toenable this system to control theregulator (start regulation, security).

The pins 1 and 2 of X8 and X9connectors are from the same signal"EMERGENCY STOP". These are 2contacts (Normally Open) that areclosed when there is no fault.

The signal on X8-4 informs that thepressure in the rail is under a pre-setlower limit (in this case the contact isclosed). This information can beused by the PLC to open the doorsof a bench when the pressure is lowenough.

The user can now switch on the electronicrack.

At this time, the user can configure thepressure regulator with the WINWINWINWINHPRHPRHPRHPRsoftware.

Depending upon the system, one or twoactuators can be controlled.

The regulation is done :

either by an ASYNCHRONOUScontrol of the actuator opening,which make a leakage or a filling thatmake pressure variation. The controlis generally of PWM type (PulseWidth Modulated).

or by a SYNCHRONOUS control ofthe actuator opening, generallysynchronized with a sensor placed inthe pump. The control can be ofPWM type (Pulse Width Modulated)or pulsing type.

The input SECURITY (X9-4), if active, willstop the regulation and the regulator willdrive the actuators so that the pressure

decreases. Depending upon the type ofCommon Rail System it will stop thecurrent in the actuator or on the contrary itwill set the current at the maximum value.

This signal has priority on all the others. Itdirectly controls the actuator card drivingstage.

Many relay outputs (X8-3 to X8-8) reportinformation (Status and faults) to externalequipments. Faults reset needs to be donevia MODBUS.

Two analogue outputs enable real time

display of the pressure in the rail..

The first one is the instantaneouspressure signal (pressure sensorsignal multiplied by 2 ).

The second one is the pressuresignal sampled at a time defined byan external signal (0v=sample,5V=Hold) or by an internal signal

generated at an angle defined by aMODBUS register.

This card generates the power supplies for the pressure sensor and interfaces thepressure sensor signal.

Two power supplies are available : +5V and +12V. They are protected against short-circuitsand have a current limitation of 100mA.

This card can operate with a pressure sensor delivering a voltage signal (0..5V) or a currentsignal (0..32mA). Selecting Voltage or Current is done via a MODBUS register. The sensorsignal can be linearized by a curve in 10 segments, these segments can be set viaMODBUS registers.

An analogue output on BNC delivers the instantaneous pressure (sensor signal multiplied by2).

An other analogue output on BNC delivers the "instantaneous pressure" sampled at a timedefined by an external logical signal "Sample/Hold" or by software , in this case a MODBUSregister defines the angle at which the signal must be sampled.

Synchronisation signals ("3600/REV" et "PUMP-SYNCHRO") are also interfaced on thiscard. The two inputs are designed for variable reluctance sensor, but they are alsocompatible with TTL signals. The detection is made on the falling edge of the signals.

The 1521 card manages the general functioning of the regulator and computes thepressure regulation.

The CPU communicates with other equipment throw a serial line (RS232 or RS485) inrespect with MODBUS protocol. It can equally communicates with a PLC (programmablelogic controller) via logical inputs/outputs interfaced by the 1526 card, for example the PLCcan start an "actuator test", or put the regulator in "security mode" or activate the regulation.

The pressure sensor signal is converted in numerical form with a 16 bits ADC / 250ksps.The software then computes the actuator command using a PID algorithm, the coefficientsP, I and D are available in MODBUS registers. A PLD (programmable Logic Device) thentransforms the PID numerical output in control signals, synchronized if necessary, with thepump rotation depending upon the Common Rail System type.

Refer to appendix REGULATION SYSTEM TYPES to get more information concerning the

functioning of these different systems.

9. REGULATION PRINCIPLE

The regulation principle can be of two types :

The asynchronous mode The synchronous mode

9.1. THE ASYNCHRONOUS MODE

The actuator(s) command is done independently of the pump position and speed. Theactuator(s) command, calculated with the PID algorithm is transformed in a PWM (PulseWidth Modulated) signal.

The pressure regulation is done throw an actuator opening control.

Mechanical functioning of the pump

It is a proportional command.

The actuator valve position is controlled. The command is done throw a PWM signaloperating at a frequency of some kilohertz, this allows a control of the average current in theactuator solenoid.

MU8244_V2_EN_V1.9 26 13 May 2008

EFS

9.2. THE SYNCHRONOUS MODE

The actuator(s) command is done in function of pump position and/or speed. Theactuator(s) command, calculated by a PID algorithm is transformed in an actuator commandsynchronized with a signal generally generated by the pump itself.

The actuator command can be a PWM or a pulsed signal, this signal control the openingtime of the actuator(s).

Opening the actuator on a known position of the pump does the pressure regulation.

Mechanical functioning of the pump

It is a TRUE/FALSE control.

The actuator valve is opened or closed. Controlling the opening time of the valve does thecommand.

Functioning:The actuator, mounted on the rail, works like a valvehaving a pressure setting depending on the averagevalue of the flowing throw current.

The actuator is driven by a PWM signal having asettable frequency (generally between 150Hz and1kHz).

It is a PROPORTIONAL functioning mode, the actuatorbeing driven by an asynchronous PWM signal.

SECURITY mode :When the actuator is not powered, it drains the rail sothe pressure decreases.In SECURITY mode, the 1522 card switches off theactuators.

Synchronisation signals :No synchronisation signal is necessary.

Functioning:The actuator(s) are mounted on the high-pressurepump. They control the admission flow in the pump.

When the actuator is not powered, the admission flowis maximum so that the pressure in the rail increases.The flow in the actuator is controlled by the averagevalue of the current flowing throw it, it is why theactuator is driven by a PWM signal at a settablefrequency (generally between 150Hz and 1kHz).

It is a PROPORTIONAL functioning mode, the actuatorbeing driven by an asynchronous PWM signal.

SECURITY mode :When the actuator is not powered, the admission flowis maximum so that the rail pressure increases.In SECURITY mode, the 1522 card continuouslypowered the actuators.

Synchronisation signals :No synchronisation signal is necessary.
