Design and Function
Solenoid locking units prevent opening of separating guards and keep
them closed as long as their is a risk of injury in the secured plant.
Attention!
!
Hazards must be ruled out before a key can be removed and
the movable part of the guard can then be opened!
The solenoid locking unit is to be integrated into a system and connected
with a control unit so that the hazardous machine can run only when the
guard is locked and closed.
An access can only be opened after a release signal was sent by the
machine control to the ZRH01A solenoid locking unit. The actuator can
only be removed from actuator module A and the access opened after
removing the key from key module 01. Key operation is forced. Key entry
ins blocked when the door is open. The key can be entered again after
the access was closed again. Only after entering the key is the solenoid
locking activated again and the machine can be restarted.
Key and magnet position are monitored by separate contacts.
ZRH01A is usually used in the system in connection with additional
STS units and SAFEMASTER products (e.g. release by speed monitor
UH 5947, standstill monitor LH 5946 or speed/standstill monitor BH 5932).
The key with forced removal can be used as protection against lock-in.

The state shown in Figure 3 does
not depend on the control signal of
the magnet.
If the control signal is applied and
the actuator inserted the solenoid
locking changes to the state of
Figure 2.
If no signal is applied and the
solenoid locking is inserted the
solenoid locking changes to the state
of Figure 1
