Design and Function

STS/K 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 entered and
the movable part of the guard can then be opened!
The STS/K 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 and the actuator removed from actuator
module B/K after a release signal was sent by the machine control to
the ZRHBM/K solenoid locking unit. The movable part of the guard can
be opened and closed as long as the release signal is still applied; the
solenoid locking is not activated. The solenoid locking is activated again
once no more release signal is applied and the guard is closed. The
machine can now be restarted.
Actuator and magnet position are monitored by separate contacts. This
makes this solenoid locking unit especially suitable for the setup mode of
a machine.
ZRHBM/K 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 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 actuator
inserted the solenoid locking changes
to the state of Figure 1
