6. Function
6.1.
Interlocking module MGB-L0.B-PN.
Together with a handle module, the interlocking module makes it possible to interlock movable guards. The combination
also serves as a mechanical door stop at the same time.
The following switch-on condition applies to safety bit
SI 9
(SK):
Ì
Guard closed (T)
Ì
Bolt tongue inserted into interlocking module (R)

17. System status table on page 33
and chapter
14.8. PROFIsafe data bytes (data block for safe
.
The interlocking module detects the position of the 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.
6.2.
Locking module MGB-L1.B-PN. and MGB-L2.B-PN.
Together with a handle module, the locking module makes it possible to lock movable guards. The combination also serves
as a mechanical door stop at the same time.
Important!
To operate the device as guard locking for personnel protection according to EN ISO 14119, the
signals for door position (T=PROFIsafe bit
SI 3
), bolt position (R= PROFIsafe bit
SI 4
) and guard
lock monitoring (Z= PROFIsafe bit
SI 5
) must be polled in a logical AND operator. This operator is
already implemented in the PROFIsafe data block (ÜK= safety bit
SI 10
).
As an alternative, you can also link the bits
SI 3
to
SI 5
individually in your control system.
The following switch-on condition applies to safety bit
SI 10
(ÜK):
Ì
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 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 into the locking module, the locking arm locks the bolt tongue in this position. Depending
on version, this locking is by spring force or solenoid force.
