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).

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 expires..
(only assigned on the drive, refer to Alarm 300911)
User agreement inconsistent: Data for the user
agreement are different in both monitoring channels after
2 sec. have expired.
%3 = status of the user agreement, NCK.
%4 = status of the user agreement, 611D.

Plausibility error, user agreement.
Pulses already cancelled during test stop selection.

(only assigned on drive, refer to Alarm 300911).
Pulses are not cancelled after the test stop time
$MA_SAFE_PULSE_DIS_CHECK_TIME.
Pulses are not cancelled for a test with external pulse
cancellation after the test stop time
$MA_SAFE_PULSE_DIS_CHECK_TIME.
NCK/drive acceptance test status differs.
Communications error between NCK and the
drive monitoring channel.
No error in this channel. Search for the cause in the other channel.
Result list 1. The functions are controlled differently via the SGEs;
evaluate the fine error coding in the 611D MDs 1391 and 1392.
Result list 2. Check the tolerance of the cams, evaluate the fine error
coding in the 611D-MDs 1393 and 1394.
