Limit Comment
32 If the limit is exceeded, the device rejects the parameter
set with an error message, restores the last valid param-
eter set and restarts using that parameter set.
16 When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring.
The red ERROR-LED lights up.
400 When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring.
The red ERROR-LED lights up.
350 When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring.
The red ERROR-LED lights up.
Limit Comment
165 When the limit is exceeded, an error message is output by
