Function
Interlocking module MGB-L0.B-PN.
Together with a handle module, the interlocking module makes it possible to inter-
lock movable safety guards. The combination also serves as a mechanical door
stop at the same time.
The following switch-on condition applies to safety bit
SI1.0 ( see also System
status table and section PROFIsafe data bytes):
ÌSafety guard closed (T)
ÌBolt tongue inserted into interlocking module (R)
The interlocking module detects the position of the safety guard and the position
of the bolt tongue.
The bolt tongue in the handle module is moved into and out of the interlocking
module by actuating the door handle.
Locking modules MGB-L1.B-PN. and MGB-L2.B-PN.
Together with a handle module, the locking module makes it possible to lock
movable safety guards. The combination also serves as a mechanical door stop
at the same time.
Important!
To operate the device as a guard lock according to EN 1088, the signals for
door position (T=PROFIsafe bit
SI0.2), bolt position (R= PPOFIsafe bit SI0.3)
and guard lock monitoring (Z= PROFIsafe bit SI0.4) must be polled in a logical
AND operator. This operator is already implemented in the PROFIsafe data block
(safety bit
SI1.0).
As an alternative, you can also link the bits SI0.2 to SI0.4 individually to your
control system.
The following switch-on condition applies to safety bit SI1.1 ( see also System
status table and section PROFIsafe data bytes):
ÌSafety guard closed (T)
ÌBolt tongue inserted into locking module (R)
ÌLocking arm in locking position (guard lock monitoring) (Z)
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 moved into and out of the locking module
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.
