EW8310 Early Warning Series Troubleshooting Guide
PROBLEM SOLUTION
Remove anti-tamper screw and cavity screw. Insert supplied Allen wrench into
mounting bolt holes in the bottom of the lock housing and turn. (See Fig.1)
Check power supply. DC power should be within 12-24VDC.
Check connections at power supply, connected releasing devices, lock
terminals and lock circuit board to magnet core.
Check to see that armature plate is correctly aligned with the
electromagnetic lock.
If there is improper alignment, make a 1/4” turn of the armature plate mounting
bolt and check for alignment.
Make sure to follow the armature mounting instructions on the template and
page 1 of this install.
This generally indicates that the lock is either operating on AC voltage or there is
some AC voltage present in the DC supply. A properly filtered and regulated DC
power supply is required to achieve optimal operation from the lock.
Ensure that switching devices are interrupting the DC power and not the AC
power supply voltage.
Ensure rubber washer on armature plate mounting bolt has not been removed
or damaged.
Check that switching device interrupts the positive wire and not the negative
wire (See Fig. 2).
Remove any Diodes or other suppression devices that may be installed.
Cannot remove the lock mounting bracket from
top of magnet for installation.
Lock is installed but has no holding force at all.
Lock has enough holding force to lightly hold a
screwdriver or set of pliers but door will not lock.
Lock is operating and locking but the armature
plate is “humming” against the surface of the lock.
Lock is not releasing immediately upon
removal of power
Inspection and Maintenance
This product and all related accessories or parts must be inspected
and maintained on a quarterly basis. Contacting surfaces of the
electromagnetic lock and armature plate must be kept free of
contaminating materials. Surfaces must be cleaned periodically
with a non-abrasive cleaner.
All mounting fasteners must be inspected on a quarterly basis.
When properly installed, the ends of the armature plate allow a
slight movement but the plate will feel secure when grasped at the
bolt. There should be no movement to the mounting bracket or
housing of the electromagnetic lock.
For added safety, thread locking compound has been provided for
the armature plate bolt and the four captive electromagnetic lock
mounting screws.
WARNING: Improper installation, maintenance, inspection or usage of the
product or any related accessories or parts may cause the electromagnetic
lock, armature plate and associated hardware to disengage and fall, causing
serious bodily injury and property damage.
PLEASE DELIVER ALL INSTALLATION INSTRUCTIONS TO THE
END-USER UPON COMPLETION OF THE INSTALLATION.
