Functional procedure
●
Only if both channels are activated "simultaneously" (by pressing one of
the enabling buttons), both output relays K1 and K2 will energize and the
output contacts 13-14 and 23-24 will close.
●
The output relays K1 and K2 will not energize if:
–
only one enabling channel was closed (in case of a defect).
–
the tolerance value for the simultaneity period is exceeded.
–
the feedback control loop S34 is open.
●
If one enabling channel is deactivated after being simultaneously activated
(by releasing the enabling button or in case of a defect), the output relays
K1 and K2 will return to their initial position again. The forced-guided out‐
put contacts 13-14 and 23-24 will open. The output relays will energize
again only after both enabling channels have been deactivated and closed
activated once again.
In this way the enabling switches avoid that one single error makes the safety
function inoperational. A single error will be recognized at the next cycle at the
latest, identifying that re-enabling is no longer possible. In case of short circuit
the monitoring device switches to "ERROR" state and has to be turned "OFF"
and "ON" again after resolving the error.
