Fault codes
The display located centrally on the control unit can
show various status ID:s (Fault codes). The Fault codes
show upon startup by pressing "Enter" or by accessing
the Service meny by using the push buttons. The fault
codes disappear from the display as soon as a lifting/
lowering motion is started.
Fault codes does not indicate any danger, but if shown
repeatedly they can help troubleshooting if the Lift
trolley behaves in an unexpected manner.
The fault code history can be cleared from the service
menu.

Any reacuring Fault codes will be saved under fault
codes.
After a problem has been diagnosed and corrected,
clearing the Fault history is advisable. This allows the
Lift Trolley to accumulate a new file of faults. By check-
ing the new history file at a later date, you can readily
determine whether the problem was indeed complete-
ly fixed.
Trouble shooting
Over-/under-temperature cut-back
1. Temperature >80°C or < -10°C.
2. Excessive load on Lift Trolley
The Lift trolley is operated by a potentiometer (placed in the
Hand control).
Fault code will indicate if potentiometer resistance is out of
limit or if there is damaged wire(s) between hand control and
control unit. Persistent fault will cause lifting motion to stop.
Replace hand control if needed.
1. Battery voltage <17 volts.
2. Bad connection at battery or controller.
1. Battery voltage >31 volts.
2. Intermittent battery connection.
The Lift trolley is operated by a potentiometer (placed on
Hand control).
Fault code will indicate if potentiometer is broken and no
control signal reaches the motor control.
1. Motor voltage does not correspond to throttle request.
2. Short circuit in motor or in motor wiring.
MCU voltage or control signals out of range.
If batteries are nearly empty the BCC controller will prevent
lifting. When this occurs Falut code 84 I logged. Plan charging
the batteries more regularly.
