Type Alert/Fault/Error Display Buzzer Chirp Sequence Possible Cause & Suggested Corrective Action
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.
Check and correct gate hardware as required.
Press RESET to clear fault.
ERROR ERROR 1
Direction Error
3 chirps per second once per
minute
Close Limit tripped after running Open or Open Limit tripped after
running Closed.
Assess cables and wire connections.
• Make sure wires are connected to the proper terminals. Make sure
gate handing is appropriate.
• Swap connections of hydraulic hoses, if necessary.
ERROR ERROR 2
IES Disconnect
3 chirps per second once per
minute
• The IES sensor could be bad, check to see that the NC contact is
intact.
• Check that you have the most current sensor; visit our website
and view the technical bulletins in the Tech Support area. The
sensor wire could be loose; you may want to tighten the female
connectors with some pliers.
• Verify the version of the software by pressing the Reset button.
The software version appears on the display. Make a note of it.
The software version should be h4.53 or h5.54 (or higher).
• If necessary, update the software using a PC laptop and S.T.A.R.T.

ERROR ERROR 3
HY5A COMM ERROR
3 chirps per second once per
minute
One or more detectors are not communicating properly. Remove
detectors, reset the controller, and re-install detectors one at a time
until faulty detector or loop is found.
ERROR ERROR 4
DUAL GATE
3 chirps per second once per
minute
Indicates a problem with the communication between the two gate
operators in a bi-parting (primary/secondary) gate system.
Check the software versions by pressing Reset or cycling power. The
version number ashes on the display (examples, h4.54 or h5.56).
The software versions on the Primary and Secondary gate should
be the same. If not, upload current software version using S.T.A.R.T.
and a PC laptop computer.
• Verify the Installer Menu item DG (DUAL GATE) is set to DG2 in
Primary and set to DG1 in Secondary gate operator.
• Make sure the wires are twisted and shielded. Refer to Dual Gate
Wiring Connections on page 86.
• Be sure the low voltage wire runs, which include the bi-parting
gate communication wires, are separate from any high voltage
wires runs. Interference occurs if wire runs are mixed or too close
to each other.
The error automatically clears when the communication fault is
resolved.
ERROR ERROR 6
DRIVE BOARD
3 chirps per second once per
minute
Internal error between the STC board and the VFD. Check cable
connections and wiring. Make sure both units are working properly.
ERROR ERROR 7
MENU CHECKSUM
ERR7
3 chirps per second once per
minute
Contact HySecurity.
ERROR ERROR 8
RPM SENSOR
3 chirps per second once per
minute
Check wiring from the hydraulic cylinder to the STC.
ERROR ERROR 9
BATT DISCONNECT
3 chirps per second once per
minute
Only applies to DC Power Supply connection. Contact HySecurity.
