SIMOREG DC Master Operating Instructions
10.2 Alarm messages
Alarm message display:
On the PMU: A (Alarm) and a three-digit number. The red LED (Fault) flashes.
On the OP1S: On the bottom line of the operational display. The red LED (Fault) flashes.
An alarm message cannot be acknowledged, but disappears automatically when the cause has been
eliminated.
Several alarm messages can be active at the same time, these are then displayed in succession.
Many alarms (see List of Alarm Messages) can only be active in certain operating states.
The system responses to an alarm are as follows:
• Alarm message is displayed on the operator panel (PMU, OP1S)
• B0114 ( = status word 1, bit 7) is set and B0115 is cancelled
(see also special alarm bits in status word 2, e.g. for an external alarm, overload, etc.)
• The corresponding bit in one of the alarm words r953 (K9801) to r960 (K9808) is set
Alarm
No.
Description
A015 Simolink start
(active in all operating states)
Although the board has been initialized, it cannot yet exchange telegrams (parameters have not yet been correctly configured
on all nodes or the boards have not yet been linked via fiber optics to form a closed ring).
A018 Short circuit at binary outputs
(active in all operating states)
Hardware monitoring function to check for short circuit at one of the binary select outputs (see also F018 and r011).
A019 Alarm message from free function block FB256
(active in all operating states)
The binector wired via parameter U104 Index.002 is in the state log.”1”
A020 Alarm message from free function block FB257
(active in all operating states)
The binector wired via parameter U105 Index.002 is in the state log.”1”
A021 External alarm 1
(active in all operating states)
Bit 28 in control word 2 was in the log. "0" state for longer than the time set in P360 index 003.
A022 External alarm 2
(active in all operating states)
Bit 29 in control word 2 was in the log. "0" state for longer than the time set in P360 index 004.
A023 Alarm message from free function block FB6
(active in all operating states)
The binector wired via parameter U104 Index.001 is in the state log.”1”
A024 Alarm message from free function block FB7
(active in all operating states)
The binector wired via parameter U105 Index.001 is in the state log.”1”
A025 Brush length too short
(active in all operating states)
When parameter P495=1 (binary sensing of brush length):
Alarm in response to log. “0” signal (longer than 10s) at terminal 211
Possible causes
• Encoder for brush length has responded
• Interruption in encoder cable
