TROUBLE-SHOOTING
Troubles and problems
The lock does not open when supply
voltage is applied.
Excessive free play of the latch (more than
4mm) while the lock is in the closed state.
A large clearance between the door and the
base as the door is closed (the latch stops
against the inside of the lock).
The lock does not fix the latch (the door is
not closed).
The door has sunk during use (automatic
latch alignment is insufficient), therefore,
the latch does not enter the lock aperture or
hits the lock as enters.

MAINTENANCE
Maintenance of the lock is performed at least once every two months and includes:
Visual inspection of the lock to check reliability of fastening. If necessary, tighten fasteners
of the lock and the latch.
Check the latch bar length. If the latch bar abuts against the lock body and this leads to
gapping between the door and the door base, or if the latch is not fixed when the door is
closed, adjust the latch bar length (see section 8).
The lock does not need lubrication!

Remedies
Using a tester, check integrity of the lock power
circuit.
Close the door, case, etc. tightly and press on it at
the latch fastening place, and apply voltage to the
lock. If the lock does not open, apply an elevated
voltage of 20-30 V (up to 36 V for a 24 V
modification) for a short time.
After the lock opening, increase the latch bar
length. To do this, fix the latch support with a
wrench, loosen the latch nut, screw out the latch
bar, tighten the latch nut.
Decrease the latch bar length. To do this, fix the
latch support with a wrench, loosen the latch nut,
screw in the bar, tighten the latch nut.
Check polarity and conformity of the lock supply
voltage to the required one.
Check the distance between the latch and the
lock; if necessary, increase the latch bar length.
To do this, fix the latch support with a wrench,
loosen the latch nut, screw out the bar, tighten the
latch nut.
Restore the door position If this is impossible,
dismantle the latch from the door. Fasten the latch
to the door ensuring alignment with the lock
aperture.
