DCS 600
Operating Instructions
4.1 Display of status, alarm and fault signals
Categories of signals
and possibilities of
display
The signals (messages) to be available for thyristor power con-
verters series
DCS 600
are subdivided into four (fifth category
see below) categories:
General messages
Starting errors
F
Fault signals
A
Alarm signals
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
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
).
For subsequent evaluation via binary outputs or serial interfaces
the 16 bit informations
FAULT WORD1
[9.01], FAULT WORD2
[9.02]
and
FAULT WORD3 [9.06]
as well as
ALARM WORD1
[9.04]
and
ALARM WORD2 [9.05]
contain several fault and alarm signals as
a binary code.
