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 removed!
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.
A key can only be removed after a release signal was sent by the machine
control to the ZRH01M/K solenoid locking unit. The machine can only be
restarted after the key was returned to its original position; key blockage
is activated then.
Key and magnet position are monitored by separate contacts.
ZRH01M/K is usually used in the system in connection with additional
STS/K units and SAFEMASTER products (e.g. release by speed monitor
UH 5947, standstill monitor LH 5946 or speed/standstill monitor BH 5932).
The key to be removed can serve as protection against lock-in or for the
operating release of additional units (e.g. M10BM/K, M11BM/K, M12M/K,
M10B01M/K).

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