Reactions:
– NC Start disable in this channel.
– Alarm display.

Remedy:
STOP F is enabled, that means a message is generated and NC start interlock is set (if only data cross-comparison is activated), or, with active monitoring, the immediate switchover to STOP B. Display on the NC/PLC interface occurs. Find the difference between the monitoring channels. The error code indicates the cause. A possible cause is that the safety-related machine data are no longer identical or that the SGEs do not have the same level (recalibrate). If no error of this type is apparent, an error may have occurred in the CPU, e.g. a “flipped” memory cell. This error can be temporary (in this case it can be eliminated by a Power On) or permanent (if it occurs again after Power On replace the hardware).
If safe monitoring was active, STOP B was also enabled automatically. It is necessary to switch the control off/on (POWER ON). Error codes for STOP F for 840D/611D:
0: No error. Definition: There is no error in this channel. An error may have occurred in the other channel. Cause, remedy: Search the cause in the other channel and interprete the error code.
