Important Note
Problem Possible Cause Solution
Door does not lock
No 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
Make sure the armature plate is not deformed
Make sure the contact surfaces of the electromagnet and armature plate are clean
and free from dust and foreign material.
Make sure the armature plate and electromagnetic lock are aligned correctly
Make sure the rubber washer was used between the bracket and armature plate
Check the electromagnetic lock is set for the correct voltage.
Check the voltage at the electromagnetic lock input. 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
Trouble Shooting
Connecting Diagram
The electromagnetic lock requires a face-to-
face alignment as shown in the Figure.

decreased to 25%.
Make sure the contact area of the
electromagnetic lock and the
armature plate is correct or the
bond sensor output function will
not work.
Wipe the surface of magnet lock
with anti-rust oil regularly.

Do not run power wires and signal
wires in the same cable or conduit.
Remove any diode installed
across the magnetic lock for
spike suppression. The magnet
is built-in with a metal oxide
varistor to prevent back EMF.
