Description
After the first output circuit is switched off, the second output circuit is switched on after the
set delay time has elapsed. The delay time can be set between 1s and 250s in increments of
1s. Before the first output circuit is switched on, the second must be switched off.
The first output circuit is switched off after the set relay delay time has elapsed; the correspon-
ding message output is switched off immediately (stop category1). The message output of the
second output circuit is switched at the same time as the corresponding relay output.
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 delay 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.
Notice
The message output is not safe. A safe maximum switch-off delay only exists for the output
circuits.
In the event of an internal error in the AS-Interface safety monitor, the output circuits are swit-
ched off immediately. For all other errors, e.g. communication interruption, the set switch-off
delay is retained.
Note
After the AS-Interface safety monitor is switched on, the second output circuit is inactive for at
least the duration of the set release time.
