Variants

Locking module ZAN
Locking module, energized on trip, emergency unlocking.
In emergency situations, for instance, in the event of confinement, the
emergency release allows for the mechanical release of an access from
outside the hazard area without the help of a tool.
With the actuation of the emergency release, 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. This opening of the circuits
must generate an emergency-stop.
Locking module ZRN
Locking module, de-energized on trip, emergency release.
Emergency unlocking in the Locking module ZRN is equipped with a lever
similar to the ZAN. After operating the lever the locking module magnet is
pressed down mechanically and the locking module function of the STS
unit is unlocked. Especially for machines with overrun time this means
that with the emergency release activated the access is open while the
machine or plant still represents hazards. When using a locking module
with emergency release we recommend combining it with acoustic and
also visual warning signals and to provide additional locking on the control
level.
When using the ZRN module within a dangerous area, it can also be used
as an emergency release.
Locking module ZRF
Locking module, de-energized on trip, escape release.
In emergency situations, for instance, in the event of confinement, the
escape release allows for the mechanical unlocking of an access from
inside the dangerous area without the help of a tool.
With the actuation of the escape release, 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. This opening of the circuits
must generate an emergency-stop.
The unit based on the locking module tuator is fastened to the movable part
of the door. Escape unlocking functions via a mechanism integrated in the
locking module and connected to a stainless steel cable. If the tension of
the stainless steel cable is increased or reduced the magnet of the locking
module is pressed down. The locking module unlocks and generates an
emergency-stop. Through the tensioning and the independent operating
direction of the cable the ZRF constantly monitors its own function.
The advantage of this version is that locked in persons can activate the
escape function even from a larger distance, e.g. injured persons no
longer able to reach the escape door. The stainless steel cable can also
be routed through a machine enclosure without having to create major
openings.
The locking module is unlocked by activating the escape release and a
trapped person can escape from the hazard area. Especially for machines
with overrun time this means that with the escape release activated the
access is open while the machine or plant still represents hazards.
This is also important in regard to self-monitoring of the locking
module ZRF. Since the stainless steel cable is constantly under tension
when installed correctly, a cable break or detachment of the mounting
elements can be detected and trigger the safety function (see installation
instructions). When using a locking module with escape release we
recommend combining it with acoustic and also visual warning signals
and to provide additional locking on the control level.

Variants
The scope of delivery includes a stainless steel cable (10 m), shroud
tensioner and a return spring in addition to the unit/module. Additional
accessories such as eyelets, return pulleys or mounting material are
separately available.
Attention! Only the actuator modules A, B and D may be installed
above a locking module ZRF and ZAF. Possible key
!
or padlock modules may be installed only above the
actuator modules B or D.
Actuator modules K and E as well as key or padlock
modules may never be installed directly above these
locking modules since they would prevent the function of
the escape release.

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.
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.
