ALARMS
– When an alarm occurs, the red FAULT LED on the front panel will blink for as long as an alarm is active. The number of flashes identifies the type of active alarm (e.g. 1 flash = A01 alarm, 2 flashes = A02 alarm,
3 flahses = A03 alarm, etc..). The meaning of the alarm is described in the following tables.
– By default, most of the protections are set to OFF (see setup menu M02). If the user wants to enable them, he has to set the parameter accordingly.
– Some of the alarms will stop thyristor switch operation (it will remain disconnected regardless of command input status), while others will be shown but DCTL will keep on operating.
– The reset of the alarm is automatic (except for internal system errors). It may take place either immediately after the alarm conditions have disappeared or after a period of time. See alarms table.
– If one or more alarms occur, the behaviour of the DCTL... will depend on the active alarms properties shown in the alarm table.
– If DCTL is connected to a DCRG8F controller by means of RS485 interface, then the status of the alarm will be shown on the controller display.
DESCRIPTION OF THE ALARMS
CODE DESCRIPTION REASON FOR THE ALARM
A01 Heatsink overtemperature The temperature of the heatsink has rised above the maximum allowed. Check air circulation inside the panel (clean filters and check cooling fan).
A02 External sensor overtemperature The temperature read by external NTC sensor has rised above the value set in parameter P02.04.
A03 Cooling fan failure The integrated cooling fan is not working properly, either not connected (not drawing current) or jammed (too high current). Check fan wiring and functioning.
Replace fan if necessary (use EXP8004 accessory only).
A04 Temperature sensor failure The internal heatsink temperature sensor is not working properly. Contact Technical support.
A05 Current too high This alarm may be triggered by the following conditions:
– Current flowing in the capacitor bank is higher than maximum value set in parameter P02.01.
– Current flowing in the DCTL is higher than maximum allowed by hardware for 100 mains cycles.
A06 THDI too high THD of the current flowing in the capacitor bank is higher than maximum value set in parameter P02.05.
A07 Current asymmetry Currents flowing in the capacitor bank are too asymmetric. Check for blown fuse or capacitor damage or wiring.
A08 Capacitor bank power too low Residual power of the capacitor bank has dropped below the minimum threshold set in parameter P02.08.
A09 Line voltage too high Line voltage higher than maximum threshold set in parameter P02.02.
A10 Line voltage not present Power voltage not present when firing command given.
A11 Communication timeout Communication with DCRG8F is not working properly. Check communication settings and/or wiring.
A12 System error Internal system error. Contact Technical support.
