Description
The external device monitoring circuit with standard slave is functionally identical to the normal
external device monitoring circuit.
As long as the safety outputs are switched off, the standard/A/B slave must be in the state
active = ON. After the safe outputs have been switched on (validation), the state of the stan-
dard/A/B slave is not relevant for set switching time. Afterward, the standard/A/B slave must
be in the inactive = OFF state again. The state of the contactor monitor is active = ON (swit-
ched on).
After the safe outputs have been switched off, the state of the contactor monitor returns to
inactive = OFF (switched off) and the state of the standard/A/B slave is not queried for the set
switching time. Afterward, the standard/A/B slave must be in the state active = ON again.
Contactor monitoring prevents the monitor from being switched back on for the duration of the
set switching time after it is switched off. This should allow all downstream contactors to reach
the idle state before contactor monitoring again queries the input signal, thereby preventing an
error lock.
