Action
Solutions
ALERT ALERT 6
Lim not released
2 chirps per second every 15
seconds
Is the pump developing
pressure? Are the brake valves
set properly? Is there hardware
holding the gate?
• Check uid levels and brake
valve settings.
ALERT ALERT 7
Freq SHIFT FAULT
2 chirps per second every 15
seconds
Hy5x detector has detected a
frequency change outside the
normal range. Likely causes
are poor integrity of loops or
metallic objects within range.
This message will also indicate
which detector alert applies
to: Exit Loop (ELD), Inside
Obstruction Loop (IOLD),
Outside Obstruction Loop
(OOLD), or Center Loop (CLD) -
(User Relay 22).
Loop lead in wires and road way
should be checked for problems
or replaced.
ALERT ALERT 8
LOOP SHORTED
2 chirps per second every 15
seconds
Hy5x detector has detected
a short circuit in the loop.
Temporarily switch detector
to be sure the loop is at fault
and then repair it. Caused by
inadequate insulation of
loop wires.
Loop lead in wires and road way
should be checked for problems
or replaced.
ALERT ALERT 9
LOOP OPEN
2 chirps per second every 15
seconds
Hy5x detector has sensed that
the loop has become an open
circuit. Check all connections
and/or use an ohmmeter to nd
out where the break is. Caused
by broken loop wire or wire
has come unplugged from
detector.
Loop and lead in wires should
be checked for problems or
replaced.
ALERT ALERT 10
I2C BUS ERROR
2 chirps per second every 15
seconds
Communication issue between
the Hy5x and the Smart Touch
Controller; reset and try again.
Replace the Hy5x if the problem
continues. Caused by removal
of HY-5B or lack of integrity of
socket connection. This message
will also indicate which detector
alert applies to: Exit Loop (ELD),
Inside Obstruction Loop (IOLD),
Outside Obstruction Loop
(OOLD), or Center Loop (CLD) -
(User Relay 22).
Remove and re-install
the HY-5B and press
RESET. Replace HY-5B,
if necessary.
ALERT ALERT 11
DETECTOR FAULT
2 chirps per second every 15
seconds
Unknown fault; perform the
megaohm test and x the loop
if necessary. Caused by a fault
within HY-5B. This message will
also indicate which detector
alert applies to: Exit Loop (ELD),
Inside Obstruction Loop (IOLD),
Outside Obstruction Loop
(OOLD), or Center Loop (CLD) -
(User Relay 22).
Remove and re-install the HY-5B
and press RESET. Replace HY-5B,
if necessary.
