4.4 Fault Signals (F)
The fault signals will be shown on the seven segment display of the
control board SDCS-CON-x as codes F . . as well as on the LCD of
the control panel CDP 31x as clear text.
All fault signals - with the exception of
F 17, F 18 and F 44 - can be
reset (after elimination of the faults);
F 20 would be self resetting, if
the communication had been re-established before.
For resetting (RESET) of fault signals the following steps are re-
quired:
• Switching off the commands ON/OFF and RUN
• Elimination of the faults
• Fault acknowledgement, i.e. resetting (RESET)
a) as described for CDP 31x
or b) by short-time setting of the command RESET
to high (logical one) via a binary input
(default setting = DI6).
• Depending on the application conditions generate the commands
ON/OFF and RUN once more.
The fault signals will result in switching off the signal
[10910] resp. in
stopping the drive (installation-dependent).
If a fault occurs, there will be three different possibilities of reaction (see
column “Remark” in the fault list):
(1) Fault will switch off the signals
energizing the main contactor, the field
contactor and the fan contactor.
(2) Fault will switch off the signals
energizing the main contactor and the
field contactor.
(3) Fault will switch off at least the signal
energizing the main contactor.
