Type Alert/Fault/Error Display Buzzer Chirp Sequence Possible Cause & Suggested Corrective Action
ALERT ALERT 11
DETECTOR FAULT
2 chirps per second every 15
seconds
Unknown fault; perform the megaohm test and x the loop if
necessary. Replace the HY-5A if the problem continues.
ALERT ALERT 12
ON TOO LONG
2 chirps per second every 15
seconds
The detector believes there has been a vehicle on the loop for more
than 5 minutes.
• Is there something metal on (or near) the loop?
• Is the sensitivity adjustment set too high?
• Is the roadway solid? If the underground loop moves it will give
false readings.
• There may be a problem with the loop itself. Check with a
megohm meter. New loops should read 100 mega-ohms or better,
between 50 and 100 operation are generally OK, below 50 mega-
ohms install a new loop.
ALERT ALERT 13
STIFF GATE
2 chirps per second every 15
seconds
The STC detects a gate that, over time, is requiring more power to
move it. Usually caused by degrading gate hardware or debris in
a slide gate track. This alert appears in the history log. It does not
affect opening or closing the gate.
• Check and correct gate hardware as required.
• Check motor brushes for excessive wear.
ALERT ALERT 14
STUCK GATE
2 chirps per second every 15
seconds
The STC detects that it cannot move the gate because of possible
broken gate hardware or ice/snow buildup.
• Manually move the gate. Verify that it moves easily and is
unobstructed throughout gate travel.
• Check and correct gate hardware, as required.
ALERT ALERT 17
BAD COIN BATTERY
2 chirps per second every 15
seconds
Turn off AC power and replace the 3V coin battery that controls the
internal clock. Use a CR2032 coin battery.
ALERT ALERT 18
CHANGE BATTERY
1 chirp a minute Batteries are not taking a charge. The STC has detected that the
24VDC UPS batteries need to be replaced.
NOTE: The buzzer will chirp every minute until the UPS batteries are
replaced.
ALERT ALERT 19
FALSE SLOWDOWN
2 chirps per second every 15
seconds
Appears only on gate operators with VFD. Slowdown switch tripped
and released (less than 1 second) in middle of run. Check for loose
wires, limits and misaligned rails or limit ramps.
ALERT ALERT 20
EXT LOCK FAILED
2 chirps per second every 15
seconds
An interlock contact is closed, indicating that the gate latch (lock)
is engaged, preventing the operator from starting. Check the
interlock terminal and wiring.
ALERT ALERT 21
DRIVE TRIP
2 chirps per second every 15
seconds
Gate travel will not occur until the alert is cleared. Any open or close
command resets the alert and starts the gate moving, unless the
VFD is experiencing a fatal error. If you cannot clear the error alert
by pressing the open or close button, contact HySecurity.
ALERT ALERT 22
INTLOCK FAILURE
2 chirps per second every 3
seconds
Appears when the RS-485 communication connection is lost for
more than 5s between interlocked (dual gate) or sequenced gate
operators. Check cable connections and wiring. Make sure both
operators are working properly and have compatible software
versions. The alert auto clears when communication between the
two operators is restored. If the operator on site is a singular gate
and the display code ALERT 22 appears, access the Installer Menu.
Verify the Installer Menu items: DG (Dual gate) and SG (Sequential
gate) are both set to zero.
