SYMPTOM
POSSIBLE CAUSES
SOLUTIONS
Exit loop activation
does not cause gate
to open.
a) Exit vehicle detector setup incorrectly
b) Defective Exit loop detector
c) Low battery with LOW BATT option set
to CLOSE
a) Review Exit loop detector settings. Adjust settings as needed.
b) Replace defective Exit loop detector.
c) Check if AC power is available. If no AC power, then running on batteries and
battery voltage must be 23.0 Vdc or higher. Charge batteries by AC or solar
power or replace batteries.
Interrupt loop does
not cause gate to
stop and reverse.
a) Vehicle detector setup incorrectly
b) Defective vehicle loop detector
c) Anti-tail set to ON
a) Review Interrupt loop detector settings. Adjust settings as needed.
b) Replace defective Interrupt loop detector.
c) Set anti-tail to OFF.
Shadow loop does
not keep gate at
open limit.
a) Vehicle detector setup incorrectly
b) Defective vehicle loop detector
a) Review Shadow loop detector settings. Adjust settings as needed.
b) Replace defective Shadow loop detector.
Obstruction in
gate's path does not
cause gate to stop
and reverse
a) Force adjustment needed
a) Refer to the Adjustment section to conduct the obstruction test and perform
the proper force adjustment that is needed.
Photoelectric
sensor does not
stop or reverse
gate.
a) Incorrect photoelectric sensor wiring
b) Defective photoelectric sensor
a) Check photoelectric sensor wiring. Retest that obstructing photoelectric
sensor causes moving gate to stop, and may reverse direction.
b) Replace defective photoelectric sensor. Retest that obstructing photoelectric
sensor causes moving gate to stop, and may reverse direction.
Edge Sensor does
not stop or reverse
gate.
a) Incorrect edge sensor wiring
b) Defective edge sensor
a) Check edge sensor wiring. Retest that activating edge sensor causes moving
gate to stop and reverse direction.
b) Replace defective edge sensor. Retest that activating edge sensor causes
moving gate to stop and reverse direction.
Alarm sounds for 5
minutes or alarm
sounds with a
command.
a) Double entrapment occurred (two
obstructions within a single activation)
a) Check for cause of entrapment (obstruction) detection and correct. Press the
reset button to shut off alarm and reset the operator.
Alarm beeps three
times with a
command.
a) Low battery
a) Check if AC power is available. If no AC power, then running on batteries and
battery voltage must be 23.0 Vdc or higher. Charge batteries by AC or solar
power or replace batteries
On dual-gate
system, incorrect
gate opens first or
closes first.
a) Incorrect Bipart switch setting
a) Change setting of both operator’s Bipart switch settings. One operator
should have Bipart switch ON (operator that opens second) and the other
operator should have Bipart switch OFF (operator that opens first)
Alarm beeps when
running.
a) Expansion board setting
b) Constant pressure to open or close is
given
a) Pre-warning is set to “ON”
b) Constant pressure to open or closed is given
Expansion board
function not
controlling gate.
a) Defective main board to expansion
board wiring
b) Incorrect input wiring to expansion
board
c) Defective expansion board or defective
main board
a) Check main board to expansion board wiring. If required, replace wire cable.
b) Check wiring to all inputs on expansion board.
c) Replace defective expansion board or defective main board
Maglock not
working correctly.
a) Maglock wired incorrectly
a) Check that Maglock is wired to N.C. and COM terminals. Check that Maglock
has power (do not power maglock from control board accessory power
terminals). If shorting lock’s NO and COM wires does not activate Maglock,
then replace Maglock or Maglock wiring (refer to Wiring Diagrams).
