Troubleshooting:
There are (9) switches that perform various functions in the system. They are:
- Over Tension Mechanical Switch – Shuts system off if over tension condition is detected.
- Under Tension Mechanical Switch – Shuts system off if under tension condition is detected.
- Low spool Mechanical Switch – Shuts system off and only allows lifting direction.
- Carriage Home Locking Pin Electrical Proximity Switch – Detects when the carriage locking pin is activated.
- Carriage at TOP position Electrical Proximity Switch - Detects when the carriage is at home position
- Motor Current sensor in control box (chip on PCB Board) – Shuts system off if over current condition is detected. Must power down and back up to continue.
- Thermal Circuit Breaker on winch Motor – Shuts winch off if activated. Must reset button on winch unit.
- (2) Wire Rope position sensing Mechanical Switches – Causes the system to stop lifting and pauses for 5 seconds or until allowed to continue lifting.
The following Conditions will cause a stop condition and require a power down and restart to correct:
- A ctivation of Motor Current sensor in control box (chip on PCB Board) - 4 RED LED Blinks on operator Control Box; Pause: then repeats).
- ( If re-setting the power does not clear the fault and the carriage will not move up or down, the unit will require a visual inspection to insure that the locking pin is not
activated prior to the carriage entering the home position – SEE BELOW .)
The following conditions will cause the system to stop and require a MANDATORY cable inspection and mechanical reset of the locking pin at the
unit to restart.
- A ctivation of the Carriage Home Locking Pin Electrical Proximity Switch with NO activation of Carriage at TOP position Electrical Proximity Switch - 5 RED LED Blinks
on operator Control Box; Pause: then repeats).
- ( If this condition is found, the cables have become crossed and require a full inspection for any damage, prior to activating the unit. Manually retracting the locking pin
after insuring no cable or other component damage has occurred will restore activation of the system. )
