Voltage Selection Jumpers
Check jumper settings before
connecting the lock to 24 VDC
input power. Damage to the
lock may result from incorrect
jumper settings.
Problem Possible Cause Solution
Door does not lockNo power
Poor contact between electromagnet and
armature plate
Low voltage or incorrect voltage setting
A secondary diode was installed across
the electromagnetic lock
Misalignment between the armature plate
and electromagnetic lock
Make sure the wires are connected properly
Check that the power supply is connected and works properly
Make sure the lock switch is wired correctly (N.C.)
Make sure if the armature plate is not misaligned
Make sure the contact surfaces of the electromagnet and armature plate are clean
and free from dust
Make sure the armature plate and electromagnetic lock are aligned correctly
Make sure if the rubber washer was used between the bracket lock and armature plate
Check the electromagnet lock is set for the correct voltage.
Check the voltage at the of input electromagnetic locks. If low, determine if the
correct wire gauge is being used to prevent excessive voltage drop.
Remove any diode installed across the magnet for "spike"
suppression. (The magnet is fitted with a metal oxide varistor to prevent back EMF)
Low holding force
Sensor output is not functioning
