Check timer (watchdog) has expired: If a channel is signaled an
SGE change in the other channel, then this is checked using this
check (watchdog) timer as to whether the change timer in
the
other
channel

Response
NC start inhibit in this channel
Alarm display
If safe monitoring was active, STOP B was also automatically triggered. It is
necessary to power-down/power-up the control (power on).
Remedy
Find the difference between the monitoring channels. The fault code %2
indicates the cause of the alarm.
It is possible that the safety-relevant machine data is no longer the same (if
required, re-load), or the safety-related inputs do not have the same signal level
(measure).
If no error of this type is apparent, an error may have occurred in the CPU, e.g.
a "flipped" memory cell. This can be temporary (in this case it can be cleared
using a power on) or permanent (if it re-occurs after power on, replace the
hardware).
Error codes for STOP F for 840D/611D:
0:
No error in this channel. Search for the cause in the other channel.
1:
Result list 1. The functions are controlled differently via the SGEs;
evaluate the fine error coding in the 611D MDs 1391 and 1392.
2:
Result list 2. Check the tolerance of the cams, evaluate the fine error
coding in the 611D-MDs 1393 and 1394.
3:
Actual position. Incorrect encoder evaluation (check MDs). Different
standstill positions have been saved.
4:
No crosswise data comparison.
5:
Function enable signals Enter equal MDs.
6:
Limit value for SG1. Enter equal MDs.
7:
Limit value for SG2. Enter equal MDs.
8:
Limit value for SG3. Enter equal MDs.
9:
Limit value for SG4. Enter equal MDs.
10:
Standstill tolerance. Enter equal MDs.
