2 ERRORS, WARNINGS AND EVENTS
2.1 ERRORS
In order to avoid dangerous situations and damages to the synchronous machine, the regulator and other
materials, the protections of the ECW500 may actuate to that certain physical limits will not be exceeded.
In this regard, an error is an improper condition of some signal or internal functionality that will be signalized in
the general fault relay, so that the operator must take some action. When an error occurs, the ECW500 cannot
be turned on until an alarm reset occurs. The most serious errors, as link overvoltage and fault on power
switches, will shut down the ECW500.
The actuation of the errors occurs as follows:
■ the regulator is disabled by removing the firing signals from de power module;
■
the HMI (keypad) signalizes that there is an error present, and its code is registered on the events list;
■ the fault relay actuates (connectors 33 and 34).
In order to enable the ECW500 again and operate it normally, it is necessary to reset it, which can be done the
following ways:
■
switching off the electronic power supply (connectors 37, 38 or 39, 40) and switching it back on (power-on
reset);
■ pressing the key on the HMI;
■
sending the command reset by the Modbus communication (address 11);
■ via specific connectors 64 and 65).
Table 2.1 Error list
ER000 Overvoltage in the power DC link
ER001 Fault on power switch S1
ER002 Fault on power switch S2
ER003 It was not possible to reset the power drive
ER004 Fault in the automatic calibration
ER005 Problem on the communication with the power board
ER006 Problem to initialize the parameters on the EEPROM
ER007 Problem to read the factory default from the EEPROM
ER008 Watchdog fault
2.2 WARNINGS
Warning messages indicate a condition occurred and that can lead to a dangerous situation. They do not stop
the regulator, but it is necessary to correct the operation.
