4.2 List of faults and alarms
33: Thyristor cannot block (V13 or V23)
34: Thyristor cannot block (V14 or V24)
35: Thyristor cannot block (V15 or V25)
36: Thyristor cannot block (V16 or V26)
41: Thyristor cannot be fired (V11 or V16)
42: Thyristor cannot be fired (V13 or V14)
45: Thyristor cannot be fired (V21 or V26)
46: Thyristor cannot be fired (V23 or V24)
99: Defective thyristor cannot be identified
Note 1:
If "Thyristor defective" or "Thyristor cannot block" is signaled, then the corresponding thyristor module should be
replaced.
Possible reasons why thyristors could be destroyed:
- Interrupted snubber circuit.
- Current controller and precontrol not optimized (excessively high current peaks).
- Cooling not guaranteed (e.g. a fan is not running, ambient temperature too high, incorrect fan direction of rotation
(incorrect rotating field), air flow too low, very dirty heat sink).
- Excessively high voltage peaks in the line supply.
- External short-circuit or ground fault present (check the armature circuit).
Note 2:
If "Thyristor cannot be fired" is signaled, then this is generally caused by a fault in the firing circuit and not by a
defective thyristor.
Possible causes:
- Firing pulse cable to the thyristor involved interrupted.
- Connector X11 or X21 incorrectly inserted.
- Flat cable X108 either not correctly inserted or interrupted.
- Defective electronics module or gating module.
- Gate cable in the thyristor module internally interrupted.
Note 3:
For a Control Module, this fault can also be initiated by other fault causes.
- Incorrect assignment of the firing pulses to the thyristors.
- Incorrect current actual value sensing connection.
- Incorrect parameterization of the current actual value sensing (p51822, p51823, p51824).
- Incorrect parameterization of the power unit type (p51825).
Remedy: Interpret the fault value and information and replace the appropriate thyristor.
