Chapter 4 - Signals and Troubleshooting

The signals (messages) to be available for thyristor power con-
verters series DCS 600 are subdivided into four (fifth category
see below) categories:
F
A
A seven segment display on the control board SDCS-CON-2 of the
thyristor power converters series DCS 600 is used to show general
messages, starting errors, fault and alarm signals.
The signals (messages) are displayed as codes. If the codes con-
sist of several parts, the characters/individual digits will be indicated
for 0.7 sec one after the other, e.g.:
0.7s 0.7s

In addition to this the DCS 600 combined with the LCD of the
control panel CDP 312 will be able to show the fault and alarm
signals as numbers with text as well as the status signals
(selected in Actual Signal Display Mode [⇒ ACT-key] by signal
group 1..xx ... 9.xx).
