The acknowledgements
FbL1 and FbL2 are also monitored in the static
condition. If there are discrepancies between the set and true condition, an
error message will be issued (
ENBL = 0) and the contactors will be
switched off immediately (
K1 = 0 and K2 = 0). The error will need to be
reset.
It is possible to reset errors via the input parameter
RSET both when ON =
0 and when
ON = 1. However, a prerequisite for setting the enable and,
when
ON = 1, switching on the contactors, is that the signals from the
feedback loops are correct.
Error messages
Any fault that is detected will be stored in the corresponding error data
word (
SSNR) of the administration data block (1st data block), until the
fault has been fully dealt with.
• Error messages in the administration data block
- Bit 00:
Fault as the signal changes at input parameter
ON,
feedback loop 1 (
FbL1) remains open
Remedy: Check contactor, contacts, cable, input card, output
card, value of input parameter
TFbL and all conditions and
then reset (input parameter
RSET)
- Bit 01:
Fault as the signal changes at input parameter
ON,
feedback loop 1 (
FbL1) remains closed
Remedy: Check contactor, contacts, cable, input card, output
card, value of input parameter
TFbL and all conditions and
then reset (input parameter
RSET)
- Bit 02:
Fault as the signal changes at input parameter
ON,
feedback loop 2 (
FbL2) remains open
Remedy: Check contactor, contacts, cable, input card, output
card, value of input parameter
TFbL and all conditions and
then reset (input parameter
RSET)
