The safety locking device is an interlocking device with a locking function. The safety
locking device consists of a safety switch and a coded actuator. The actuator has a high
coding level (uniquely coded).
Function
When the protective device is closed, the actuator is inserted into the actuating head of
the safety switch. In doing so, the locking pin is pressed downward by the actuator. If
the actuator reaches the end position, the locking pin moves into the provided hole of
the actuator.
Further functioning depends on whether the safety locking device is based on the
power to release or the power to lock principle.
•
In the power to release principle, the inserted actuator is immediately blocked and
the locking device is locked (to unlock the locking device, the locking solenoid
must be energized).
•
In the power to lock principle, the locking solenoid must be energized in order to
lock the locking device. If the locking solenoid is not energized, the actuator is only
held in position by retaining force (spring force). The actuator can be pulled out
again by overpowering the retaining force.
Complementary information
•
The code of the actuator is read out and evaluated using transponder technology.
If the code is valid, the door application diagnostic output (Out AUX DOOR)
switches to the ON state.
•
If the locking device is locked, the safe output signal switching devices (OSSD) are
switched to the ON state. In addition, the locking function application diagnostic
output (Out AUX LOCK) switches to the ON state.
