Important!
Prior to use read the operating instructions and the system manual, and keep
these in a safe place. Ensure the operating instructions and the system manual
are always available during mounting, setup and servicing. EUCHNER cannot
provide any warranty in relation to the readability of the CD for the storage pe-
riod required. For this reason you should archive a printed copy of the system
manual. If you should lose the operating instructions or the system manual, you
can download these documents from www.EUCHNER.de.
Function
Together with a handle module, the locking module makes it possible to lock
moveable safety guards. The combination also serves as a mechanical door stop
at the same time.
The following switch-on condition applies for the safety outputs O
A
and O
B
(see
also System status table):
Safety guard closed
Bolt tongue inserted in the locking module
Locking arm in locking position
Both safety inputs (IA and IB) must be on
The locking module detects the position of the safety guard and the position of
the bolt tongue. The position of the locking arm is also monitored.
The bolt tongue in the handle module is retracted and extended by actuating the
door handle.
When the bolt tongue is fully inserted in the locking module, the locking arm locks
the bolt tongue in this position. Depending on the version, this locking is by spring
force or solenoid force.
Version MGB-L1-AR-...
The locking arm is held in the locked position by spring force and is unlocked by
solenoid force (closed-circuit current principle).
Version MGB-L2-AR-...
The locking arm is held in the locked position by solenoid force and is unlocked by
spring force when the solenoid is switched off (open-circuit current principle).
Warning!
The safety guard can be opened immediately in the event of interruption of
the solenoid power supply!
Usage only in special cases in accordance with strict evaluation of the acci-
dent risk (see EN 1088:1995+A2:2008, section 5.5).
Typical case: If the risk of accidental locking inside a safety guard during a power
failure is higher than the risk of ineffective guard locking.
