Power Supply Integrity Test Indicating Fluctuating Voltage
Fluctuating voltage encountered while performing the test in section 5.3 is the result of
defect in the electrical system. This flow chart pertains to units consisting of one power
supply providing for one prox.pad plus, one electric lock, and any accessories (for
example, motion egress detector).
Check circuit breaker, or obtain assistance of a
licensed electrician.
NOTE: A glitch in the prox.pad plus program might result from using a
power supply that is not filtered and regulated properly. For extra filtering
suggestions, call IEI technical support.
1. Acquire an alternative power supply that matches
unit voltage, battery preferred. 2. Disconnect
prox.pad plus power by removing wires from the (+)
and (-) wires at prox.pad plus. 3. Connect
alternative power to prox.pad plus and re-test per
section 5.2.
Bad
prox.pad
plus
Meter and verify that voltage from electrical outlet
is in tolerance.
NO
Resolve and re-test per instructions in
section 5.3.
YES
1. Disconnect all accessories and lock from
prox.pad plus. 2. Re-connect original power
supply. 3. Re-test per instructions in section
5.3.
FAIL
Ensure power supply donates ample power by
adding the max. current draw of each device.
(Total AMPs should be less than provided by
power supply.)
PASS
FAIL
If applicable, ensure the lock's power selection
jumper is selecting proper voltage setting. (In
wrong position, current draw doubles.)
PASS
A larger power
supply is required.
FAIL
Problem is prior to
the prox.pad plus.
PASS
The following are possible causes for negative
test results. To resolve, try and isolate each
device by swapping or removing from the circuit
one part at a time.
-Defective power supply not producing rated amount.
-Defective power supply no longer producing rated amount.
-Defective battery loading down the unit.
-Nick or crack in conductor acting like an in-line resistor.
-Return to step 3 in section 5.3 and continue.
