Errors, Warnings and Events .

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).
