Trouble ShootingPrimary Actions

Automatic Error Detection

Automatic and manual self test that test all errors and can locate the exact phase and group of the fault.

Self Diagnostic System

E3– Unable to Connect Capacitor Group

E5- Misfiring

E6- Network Synchronization

E7- Over Temperature

E10-Resonance

The Errors

Errors that do not disable the system completely will be indicated in the upper section of the controller screen and will indicate to which group the error is associated.

Error Identification

Errors that disable all of the system operation will be displayed on the main section of the controller screen.

Error Identification

Unable to connect Error Monitored Signals: X (reactance) of the connected capacitor(s), on all three

phases.

Averaging/Delay: 8 consecutive network cycles of exceeding the limit.

Limits: 10% from nominal value.

What action is taken: The particular group is disconnected and disabled.

Error Reset: Automatically (see below) or manually by activating self test.

Automatic Reset Delay: The system repeats the self test on defective groups only, after 1 minute. If the same groups are detected faulty again, the test repeats after 2 minutes and the interval is doubled each test until maximum 10 repeats (with delay of 512 minutes = 8.5 hours). If the result of each test is not identical to the previous one – the repeat interval is set back to 1 minute.

How to test the firing ?

Misfiring Monitored Signals: THD of capacitor current in the first two phases.

Averaging/Delay: 2 consecutive network cycles of exceeding the limit.

Limits: 300%.

What action is taken: The particular group is disconnected and disabled. If detected during normal operation – self test is activated.

Error Reset: Automatically (see below) or manually by activating self test.

Automatic Reset Delay: The system repeats the self test on defective groups only after 1 minute. If the same groups are detected faulty again, the test repeats after 2 minutes and the interval is doubled each test until maximum 10 repeats (with delay of 512 minutes = 8.5 hours). If the result of each test is not identical to the previous one – the repeat interval is set to 1 minute.

Error 5

Test all the relevant firing cables and connectors disconnect and reconnect the connectors and test the system again.

Disable E5 and test if the system works properly now, test the Thd of the network if it is very high maybe the E5 should be disabled .

If this is not the case the controller firing card or the SWM firing card are the next suspects.

Sometimes because of E3 in one phase E5 can be detected but the cause is E3, reactors shortcut can also cause E5.

Error 5 handling

Network synchronization

Monitored Signals: L1-L2 Voltage (in three phase system).

Averaging/Delay: 500 consecutive network cycles of internal PLL synchronization error.

Limits: Internal PLL failed to synchronize to signal.

What action is taken: System disconnects.

Error Reset: Automatically.

Automatic Reset Delay: 250 consecutive network cycles of error-free PLL operation.

Error 6

Test the voltage in L1- L2 terminals of the controller (with a multimeter) a valid voltage signal Should be detected.

If a valid voltage is not detected make sure that the controller will receive the signal.

If there is a valid voltage in the terminals the controller should be checked.

Error 6 Handling

Over Temperature

Monitored Signals: External Thermostats.

Averaging/Delay: Immediate.

Limits: Depends on external thermostats.

What action is taken: System disconnects.

Error Reset: Automatically.

Automatic Reset Delay: Immediate.

Resonance Monitored Signals: Mains and Load current, on all three phases and 63 harmonics.

Averaging/Delay: 10 consecutive network cycles of exceeding the limit, counted for each phase and harmony separately.

Limits: IMAIN-ILOAD>X%*ICAP(NOMINAL). X% is 50% for normal limit and 30% for sensitive limit.

What action is taken: System disconnects.

Error Reset: Automatically.

Automatic Reset Delay: The system disconnects for 10 seconds for first occurrence and doubles the time for each occurrence happened within 20 seconds from the end of previous disconnection, until a maximum of 3000 seconds.

Error 10

Measurements must be performed and analyzed to understand the source of resonance.
