HOW IT WORKS
When power is applied to the magnetic lock, it turns on the unit's powerful built-in electromagnet. This electromagnet is
attracted to the steel armature plate which is mounted on a door, holding the door fast against unauthorized entry. When
power to the magnetic lock is turned off, the electromagnet releases the armature plate, allowing the door to open. In
addition, the E-941SA-1K2PD has built-in LEDs to show electromagnet status, plus a status sensor to monitor whether the
door is securely closed, and a built-in adjustable-delay locking timer.

REGULAR MAINTENANCE
• Clean the contact surfaces of the electromagnet or armature plate with a soft cloth and non-abrasive, non-corrosive cleaner.
• Apply a light coat of a silicon lubricant to prevent rust. Wipe away the excess.
• Check that the armature plate is securely attached to the door, yet can pivot slightly around the armature screw.
• Check that the electromagnet is securely attached to the door frame.
TROUBLESHOOTING
Problem:
• Door does not lock
• Status LED is not
illuminated
Door locks, but can be
easily forced open
Delay in door
releasing
No relay output
Delay in door relocking
Possible cause:
No power
Poor contact between
electromagnet and armature
plate
Incorrect voltage setting
• A secondary diode was
installed across the
electromagnet
• No power
• Misalignment
• Check timer
Solutions:
• Check to make sure the wires are securely tightened to the
terminal block.
• Check that the power supply is connected and operating.
• Make sure the lock switch is wired correctly.
• Make sure the electromagnet and armature plate are
properly aligned.
• Make sure the contact surfaces of the electromagnet and
armature plate are clean and free from rust.
• Check the power leads with a meter, and make sure 12VDC
or 24VDC is present.
• The electromagnet is fitted with a metal oxide varistor to
prevent interference, so do not install a secondary diode.
• Check that the power is connected and operating.
• Make sure the lock is aligned properly.
• Make sure the NO/NC/COM are wired properly.
• Make sure timer is adjusted to desired delay time.
