TROUBLE-SHOOTING
Troubles and problems
Remedies
NC lock does not open when supply voltage
is applied.
NO lock does not close when supply
voltage is applied.
Using a tester, check integrity of the lock power
circuit.
Check polarity and conformity of the lock supply
voltage to the required value.
Check the presence of the required clearances
(see section 6).
The lock closes with difficulty, the catch
does not operate smoothly.
Check the presence of the required clearances
(see section 6).
Check whether the locking plate and the fastening
plate are skewed, if necessary, remove skewing.
In case of strong rubbing of the catch against the
locking plate, lubricate the places of contact with
grease (SHRUS).
The door has sunk during operation,
therefore, the catch does not enter the
opening in the locking plate.
Restore the door position If this is impossible,
remove the locking plate from the door. Fasten the
locking plate to the door providing the required
clearances.
NC lock does not close when supply
voltage is applied.
NO lock does not open when supply
voltage is applied.
Check the presence of required clearances
between the catch and the locking plate (see
section 6)

MAINTENANCE
The lock Promix-SM213 is lubricated by the manufacturer and does not need additional
lubrication or any special maintenance. However, if dust or dirt penetrated inside the lock during
service, and the lock began to show malfunction, then dismantle the lock, unstick the protective
film carefully from the slot in the body. Wash the lock immersing it in white spirit or petroleum
solvent with the catch downwards, to a depth of the thinned portion of the body (not deeper!).
Dry the lock and make sure that its operability has restored. Lubricate inner walls of the body
and slot ends through the slots, without sinking the catch; use a water-resistant, antifriction plastic
grease (e.g., SHRUS).
