Technical Data

ATTENTION !
!
To avoid wrong usage (e.g. by overload, mounting position
or usage in acid, alkaline or other hostile ambient condi-
tions) the limitations of the product have to be observed.
Please check in advance if your application requires the
usage of the more robust stainless steel model of SAFE-
MASTER STS. The requirements of the mounting and ope-
rating instruction must be fulfilled.

Variants

Locking module ZAN/K
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/K is equipped with a
lever similar to the ZAN/K. After operating the lever the locking module
magnet is pressed down mechanically and the locking module function
of the STS/K 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/K module within a dangerous area, it can also be used
as an emergency 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.
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.
With the load current principle the control signal for the magnet is inverted
(see switching logic).
