Application example for
“Mandatory safety door
opening” operating mode
In this example, the user enables the guard locking device with the “SWITCH” function block
created by a button. The “L
OCKOUT” signal controls the output for controlling the guard lock-
ing magnets. The feedback signal from the guard locking pin is acquired using the “LOCK
FEEDBACK” function block. The “O
UT” output enables the actuators. The status of the door
is monitored by the “G
ATE” input via the “GUARD-MONITORING (2CH)” input function
block.
The guard locking device used in the example remains in the locked position if the electro-
magnet is not energized, which is why the “Interlock Spring” option must be selected.

ing mode
Figure 5-120 Signal behavior in the example for the “GUARD-LOCKING” function block
in “Mandatory safety door opening” operating mode
In the example illustration, observe the circuit diagram (left) and the parameters (right) of
the “GUARD-LOCKING” operator. The feedback of the electromagnet consists of two
contacts: a N/C contact and a N/O contact. If the electromagnet is energized, both con-
tacts change status. In contrast, the position monitoring of the safety door consists of two
N/C contacts.
