Function
Interlocking module MGB-L0.B-PNA
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 SI9 (see also System status
table and section PROFIsafe data bytes):
Ì Safety guard closed (T)
Ì Bolt 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 module MGB-L1.B-PNA and MGB-L2.B-PNA
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), bolt position (R) and guard lock monitoring (Z) must be polled in a
logical AND operator. This operator is already implemented in the safety bit SI10.
As an alternative, you can also link the bits SI3 to SI5 individually in your control
system.
The following switch-on condition applies to safety bit SI10 (see also System status
table and section PROFIsafe data bytes):
Ì Safety guard closed (T)
Ì Bolt tongue inserted into locking module (R)
Ì Locking 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.
