Locking module ZRN, ZAN
with emergency unlocking

Product Description

Locking modules ZRN, ZAN, ZRF und ZAF are assembled with other
modules to an STS unit. They serve as a solenoid lock of separating
guards on machines with cycle or overrun times or other hazards, which
may still be present even after the access query. It must therefore be
ensured that there is no hazard remaining when removing the actuator
or key and access can be unlocked.

Approvals and Markings

Design and Function

Extremely rugged and flexible solenoid lock monitoring the safe position
of an access in the system. For this purpose the modules are used in
combination with other mechanical modules, for instance, actuator, key
and/or padlock modules.
Access can only be released after the safety of the equipment has been
ensured for the operating personnel.
With ZRN and ZRF an access can only be opened when a signal is
applied to the magnet. In addition, both modules offer protection against
lock-in. In emergency situations a door can be opened through manual
operation of the emergency release (ZRN) or escape release (ZRF)
without a signal being applied to the magnet.
ATTENTION!
Locking modules ZRF and ZAF may not be used without
!
actuator module only to release keys in a key interlock
system.
Only the actuator modules A, B and D may be installed
above a locking module ZRF and ZAF. Actuator modules
K and E as well as key or padlock modules may never
be installed since they would prevent the function of the
escape release.
However, key modules 01, 01S as well as padlock module V can be
installed above an actuator module B or D.
With the Locking modules ZAN and ZAF an entry can be opened
when no signal is applied to the magnet. In addition, this module offers
possible protection against lock-in. A door can be released in emergency
situations by manually operating the emergency or escape release.
ATTENTION!
The modules ZAN and ZAF may be used only in connection
!
with the mechanical modules e.g. key modules 01, 01S,
padlock modul V or an actuator module A, B, D. Combination
with other mechanical STS modules is not permitted and
may cause the unit to be blocked.
