Product Description

Locking modules ZRX, ZAX and ZRH are assembled with other modules
to an STS unit. They serve as a solenoid lock of separating guards on
machines, e.g. with cycle and overrun times or other hazards which may
still be present even following access queries. 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

An extremely robust and flexible solenoid lock, which monitors the safe
position of one or more entries in a system, for instance, of a guard or
protective door. For this purpose the module is used in combination with
other mechanical modules, for instance, actuator, key and/or padlock
module. The key and padlock modules can only be installed above the
locking module.
The entries can only be released after the safety of the plant for the
operating personnel has been ensured.
The locking modules ZRX, ZAX and ZRH with manual unlocking can
also be used without actuator module only for releasing keys in a key
interlock system. This function is used in key interlock systems with
central shut-off or shut-off outside the system, for instance in Ex zones,
with strong vibration or dirt build-up, etc.
When installing one of the modules e.g. key module 01, 01S, padlock
module V, actuator module B, D or A above a locking module ZRX and/
or ZRH, their release only takes place after applying a control signal to
the magnet of the locking module. If emergency or escape unlocking is
required, please refer to data sheet locking module ZRN, ZAN and ZRF.
