Variants

Locking module YRX/K
Locking module, de-energized on trip, without additional functions
Locking module YRH/K
Locking module, de-energized on trip, with manual unlocking.
In case of electrical faults, for instance, during power failure, the manual
unlocking allows the mechanical release of a locking module with the
help of a tool.
With the operation 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 Contact
between 10 and 11 will be closed.
The manual unlockings are not sealed or lead-sealed because of the
typically rugged application areas. 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.
Locking module YAX/K
Locking module, energized on trip, without additional functions
Function inversion with locking modules
The locking modules YRX/K, YAX/K and YRH/K can also be combined
with the actuator module K/K.
In this case the locking module no longer works as a door closure but
rather unlocks mechanically functioning units for actuator removal. This
combination is suitable for systems with a very high risk of being locked in
where escape unlocking cannot be used; it is also used for escape sluices.
The magnetic contacts of the locking module can only be used as signal
contacts in this application. With a safety-related 2-channel contact use
of the actuator / key position a safety switching device with changeover
contact principle or antivalence switching is required. For more information
refer to the data sheet for the actuator module K/K.

Examples

YRHK01M/K
This unit functions similar to the MK01M/K, but the actuator can only be
introduced into the actuator module if a signal is applied to the solenoid of
the locking module unit.
YRH11BM/K
This unit functions similar to the ZRH01BM/K, however, an (authorization)
key must first be inserted when a signal is applied to the electric magnet
of the locking module. After this the 2nd key can be removed and the
actuator can then be pulled from the actuator module to open the access.
YRH10BM/K
This unit functions similar to the ZRHBM/K, however, an (authorization)
key must first be inserted when a signal is applied to the electric magnet of
the locking module. The actuator can then be removed from the actuator
module to open the access.
YAX11BM/K
This unit functions similar to the ZAX01BM/K, however, an (authorization)
key must first be inserted when a signal on the electric magnet of the
locking module is obsolete. After this the 2nd key can be removed and the
actuator can then be pulled from the actuator module to open the access.

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
locking 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 always be included again 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
subsequently pushing back the magnetic tappet (refer to the SAFEMASTER
STS/K Installation and Operating Instructions).
A SAFEMASTER-STS/K locking module based on the load current principle
with manual unlocking is not available since it releases in the event of a
power interruption.
