Variants

Locking module ZRX/K
Locking module, de-energized on trip, without additional functions.
Locking module ZRH/K
Locking module, de-energized on trip, manual unlocking.
In the case of electrical faults, for instance, during power failure, the manual
unlocking allows the mechanical release of an access from outside the dan-
gerous area with the help of a tool.
With the actuation of the manual unlocking, the circuits on terminals 7 and
8; 9 and 11 as well as 17 and 18 will be cut off at the same time and contact
between 10 and 11 will be closed. Opening of these circuits must generate
an emergency-stop.
The manual unlockings are not sealed or lead-sealed because of the
typically rugged applications. When using a locking module with manual
unlocking we therefore recommend combining it with acoustic and also
visual warning signals and to provide additional locking on the control level.
Zuhaltemodule ZRHC.001 und ZRHC.002
Zuhaltemodul, Ruhestromprinzip, Hilfsentriegelung
Für Anwendungen, bei denen bis zu 3 Befehlsgeber pro Modul
eingebunden werden können.
Locking module ZAX/K
Locking module, energized on trip, without additional functions.
Locking modules YRX/K, YRH/K and YAX/K
For applications where the key modules 10/K, 10S/K or an actuator module
K/K or padlock module W/K shall be installed above the locking module,
the YRX/K, YAX/K and YRH/K versions are available. Additional information
about the circuit diagram and use of the locking modules YRX/K, YAX/K and
YRH/K is available in the data sheet locking module YRX/K, YAX/K and
YRH/K as well as in data sheet actuator module K/K.

Important Notes

Function differences of locking modules with load current principle
and locking modules with standby current principle.
Locking modules based on the standby current principle are in de-energized
condition when in the locked position. This must be remembered especially
when examining faults such as power failure or wire break.
Only when the safety evaluation shows, that a solenoid lock with closed
circuit operation is not suitable or is not required, a solenoid lock with open
circuit operation can be used.
See DIN EN ISO 14119:2014-03 Abs. 5.7.1.
Contrary to the locking modules based on the standby current principle lo-
cking modules based on the load current principle lock only when the circuit
is closed. The locking modules unlock if the circuit opens with the
load current principle.
If a locking module is used based on the load current principle terminals
7 and 8 or 17 and 18 must be included in the safety circuit.
With the load current principle the control signal for the magnet is inverted
(see switching logic).

Manual unlocking
If misuse of the manual unlocking must be suspected a locking module
based on the standby current principle without manual unlocking can also
be used as an alternative. In the event of a power interruption the locking
module must be unlocked in this case by removing the cover and subse-
quently pushing back the magnetic tappet (refer to the SAFEMASTER
STS/K Installation and Operating Instructions).
A locking module based on the load current principle with manual unlocking
is not available since it releases in the event of a power interruption.
