The 7500 Series is a (PL) Electric Power to Lock Unit which is failsafe in that it unlocks when power is removed. The most
commonly used function is the 7540 and 7550 models which are locked when energized on the outside and free on the
inside for egress. Models 7510, 7520 and 7530 lock on both sides when energized.
(1) Power on controller plunger
does not throw 1A Check voltage with a meter at the lock
farthest from source with all locks energized.
Meter should indicated the same voltage
stamped on the solenoid body. If voltage is
low either too small of a wire gauge was
used or there is too great of a load on the line.
1B Adjust plunger evenly.
