FAULT FAULT 2
PHOTO EYE
FAL2
2 chirps per second once per
minute
“Monitored” means the
Controller must see the photo
eye N.C. contact change from
open to close after receiving
the command to run, but before
starting the motor. FAULT 2
indicates the controller did not
see this sequence when the gate
received a run command.
Check the wiring. Refer to the
wiring diagram associated with
the attached sensor. See Wiring
HySecurity Sensors: Smart Touch
on page 131.
Be sure the eye “common” wire
is wired properly to the SENSOR
COM terminal.
FAULT FAULT 3
LOW VOLTAGE SAG
2 chirps per second once per
minute
The 24V control voltage is
monitored in lieu of line voltage.
Low incoming line voltage will
cause low control voltage. Verify
that the control transformer is
connected properly, (white – not
used, red for 208V, orange for
230V and blue for 460V). Check
the line voltage as the motor
starts with a meter that has min/
max hold capability. If the line
voltage drops more than 10%
below nominal (187 on 208VAC,
207 on 230VAC, or 416 on
460VAC) the voltage is dropping
too low and must be corrected.
This condition is often caused
by loose connections or the wire
size being too small. If the wire is
too small, it must be replaced.
FAULT FAULT 4
GATE NO LOAD
Smart Touch Controller has
detected there is no load
on operator. Gate is non-
operational while this fault is
triggered.
• Motor wires disconnected.
• DC switch off.
1. Check DC motor wires.
2. Turn DC power switch on.
3. Press RESET to clear fault.
FAULT FAULT 5
LIMIT FAILED
2 chirps per second once per
minute
50VF series only.
Not applicable for
StrongArm M30/M50.
Slow down to stop
limit took too long.
Possible bad limit
switch.
• Verify limits and placement of
slow down limit ramps.
• With drive wheels clamped,
test Open (GATE OPENING
appears on display). Test Close
(GATE CLOSING appears on
display.
FAULT FAULT 14
STUCK GATE
2 chirps per second once per
minute
The STC has tried 3 times to
overcome a stuck gate. The gate
is non-operational while this fault
is triggered. Caused by broken
gate hardware or ice/snow
buildup.
1. Check and correct gate
hardware as required.
2. Press RESET to clear fault.
