gate.
Alarm sounds for 5 a) Double entrapment occurred (two
minutes or alarm obstructions within a single activation)
sounds with a
command.
Alarm beeps three a) Low battery
times with a
command.
On dual-gate a) Incorrect Bipart switch setting
system, incorrect
gate opens first or
closes first.

given
Maglock not a) Maglock wired incorrectly
working correctly.
TROUBLESHOOTING
SOLUTIONS
a) Refer to the Adjustment section to conduct the obstruction test and perform
the proper force adjustment that is needed.
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.
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.
a) Check for cause of entrapment (obstruction) detection and correct. Press the
reset button to shut off alarm and reset the operator.
a) Check if AC power is available. If no AC power, then running on batteries and
battery voltage must be 11.5 Vdc or higher. Charge batteries by AC or solar
power or replace batteries
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)
a) Pre-warning is set to "ON"
b) Constant pressure to open or closed is given
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).
