Suggested Corrective Action
ENTRAPMENT MODE
ALERT
4 to 5
chirps/s for
5 minutes
or until
cleared
Occurs when the inherent sensor is tripped
when the gate is already in Safe Mode. The
operator will not function until it is reset,
which can occur by:
• An Open or Stop command
•
A Reset button command or a Fire
Open command.
With any one of these inputs, the operator
will return to Safe Mode. Barrier arm
binding or wind can cause a false alert.
1. Remove the obstruction.
2.
Correct the gate hardware or
temporarily, remove the arm in
high wind conditions.
SAFE MODE
ALERT
Occurs when either the edge sensor
or inherent sensor has been tripped. In
Safe Mode, the automatic close timer is
disabled, but any command will reset and/
or start the gate in motion. Safe Mode
clears when full travel is reached or the
RESET button is pressed. Note that too
tight of a spring on the DC14, hardware
binding, or wind can cause a false alert.
1. Remove the obstruction.
2. Correct the gate hardware.
3.
Adjust spring tension on a
StrongArmPark DC14
NO AC POWER
ALERT
Chirps
once
whenever
the gate
reaches
the close
limit
AC power is shut off at the source (breaker)
or is not connected. The AC power switch
on the operator (lower rocker switch) is
turned off, or the circuit breaker on the
operator has tripped.
1. Have a licensed electrician check
the wiring.
2.
Connect AC power to the
operator.
3. Reset circuit breaker at electrical
panel. Reset the operator circuit
breaker.
4. Turn AC power switch on.
LOW 24VDC
ALERT
Flashes on
display 1s
every 5s
Occurs when the battery voltage has
dropped to less than 22 Volts. At this level,
the batteries are 80% depleted.
NOTE:
Functionality of the controller
board becomes impaired when the voltage
drops below 21 Volts.
1. No AC Power. See above item.
2. Check all wiring connections.
Clean or repair as required.
3. Check the following and replace,
if necessary:
•
Battery condition
•
Charger failure. Check charger
voltage
• SDC
• Transformer
DEAD BATTERY
ALERT
3 chirps
upon any
operating
command
entry
Extremely low UPS batteries – no
automatic operation - batteries below 21
Volts. At this level, the batteries are 90%
depleted. The gate will automatically
open or close depending upon the setting
chosen. Gate movement is possible,
but limited to push button control until
batteries reach 18 V.
See corrective action above.
