Description
After the first output circuit is switched off, the second output circuit is switched on if the zero-
speed relays report that machine standstill has occurred. Zero-speed relays are to be assigned
as devices to the second output circuit.
In order to also facilitate the release of the door lock during communication disturbances and
other errors, the set delay time is adhered to for inactive zero-speed relays. This release time
is the time between the switching off of the first output circuit and the switching on of the se-
cond. The release time can be set between 1s and 300s in increments of 1s.
Before the first output circuit is switched on, the second must be switched off. If the validation,
ON state, is performed again before the second output circuit is switched on, the first output
circuit is switched back on and the second remains switched off.
Unlocking device function
After the first output circuit is switched off (e.g. following an emergency shutdown), the second
output circuit is switched on after the set release time has passed (or by the zero-speed relays)
so that the doors unlock. This unlocking is not always desired. By enabling Unlocking device
(checkbox activated), a standard slave can be specified. The state (LOCK signal) of this stan-
dard slave determines whether or not the locking is to be retained even after the release time
has passed. When the machine is switched off, the LOCK signal can thus be used to freely
turn door locking on and off.
Restart/Reset of error condition option for safe AS-Interface output (actuator)
If an AS-Interface safety monitor is configured with safe AS-Interface output (control of safe
AS-Interface actuators) in the Information about monitor and bus, devices for the reset of error
condition and the restart of the actuator must also be configured. After inserting the output de-
vice in the configuration, this is apparent from the 2 dummies for the restart and reset of error
condition devices.
Assign the dummies for restart and reset of error condition the desired devices by using
drag&drop to move devices from the icon library onto the dummies.
Note
After the AS-Interface safety monitor is switched on, the second output circuit is inactive until
the monitored movement has come to a standstill, however for no longer than the duration of
the set release time.
Note
For an automatic restart, simply assign the restart dummy the TRUE system device.
