This fault can only occur if the special supervised photo eye function is enabled in the Installer Menu. See
Installing
Photoelectric Sensors For Secondary Entrapment Protection Only
for details.
Correct malfunctioning photo eye.
FAULT 3 VOLTAGE SAG
Not used in SwingSmart. Caused by inadequate supply wire size. Correct AC supply to use longer wires.
FAULT 4 GATE NO LOAD
The Smart DC Controller has detected there is no load on the operator. The gate is non- operational while this fault is triggered.
Several possible causes: - Linkage failure. - Taper clamp being too loose. - Broken drive belt. - Motor wires disconnected.
1. Correct linkage. 2. Tighten taper clamp. 3. Replace drive belt. 4. Check DC motor wires. 5. Press RESET to clear fault.
FAULT 5 LIMIT FAILED
Not used in SwingSmart.
FAULT 14 STUCK GATE
The Smart DC Controller 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.
ERROR 1 DIRECTION ERROR
The Smart DC Controller has detected that operator ran in the wrong direction.
Several possible causes: - Limit switch wiring. - Motor wiring. - Debris on limit plate
1. Check limit switch wiring and correct, as needed. 2. Check motor wiring and correct, as needed. 3. Remove debris from the limit switch area. 4. Press RESET to clear fault.
ERROR 3 HY-5A FAILED
The Smart DC Controller has detected a communication error with a HY-5A vehicle detector.
Caused by removal of HY-5A or lack of integrity of the socket connection. This message will also indicate which detector the alert applies to: Exit Loop (ELD), Inside Obstruction Loop (IOLD), Outside Obstruction Loop (OOLD), or Center Loop (CLD).
1. Press RESET. 2. Remove and re-install the HY-5A. 3. Replace the HY-5A, if needed.
