8.4.3. Lock adjustment
Lock adjustment consists in determining the height on which it must be installed.
The screws fixing the lock and also serving the purpose of adjustment are presented on
fig. 34 - they are labelled as item "2". Adjustment may be performed
within a range of
about 5 mm. After correcting the height (if necessary), tighten the screws
and protect the
lock from unintended moving using a counter self-drilling screw - labelled as item "1" on
figure 34.
Another optional lock adjustment is adjusting the electromagnet armature fixture.
After closing the armature, it should contact the electromagnet at its full area. If a situation
shown on fig. 38 occurs when the armature does not shut completely, adjust it so that the
electromagnet surfaces and the armatures lie parallel towards each other after shutting.
If the lock does not operate correctly, the reason may be its wrong adjustment. The
above adjustment actions must then be carried out.
