Maximum battery voltage
-
Eye alarm code: 1
-
Alarm level: 1
-
Alarm cause: battery voltage, measured by a circuit inside control unit, exceeds
following levels:
63 V, in case of systems working at 36 V
63 V, in case of systems working at 48 V
If the controller detects such a fault, refer to following troubleshooting procedure:
1. such an alarm can be caused also by the presence of regeneration currents; when lift
truck is on release or reverse braking ramp, motors work as generators, and battery
voltage can exceed overvoltage limit. In a case like that, the battery condition should
be verified ( if the battery is new it is necessary to do some charge-discharge cycles
before reaching the rating declared by the constructor) or has a high internal
resistance. If the case is the second and it is not possible to change the battery, the
solution may be to reduce the release and reverse braking ramp.
2. incorrect wiring to battery positive or negative terminals.
3. verify if battery is still in good conditions.
4. replace the control board .
Minimum battery voltage
-
Eye alarm code: 2
-
Alarm level: 1
-
Alarm cause: battery voltage, measured by an internal circuit, is lower than following
levels :
24 V , in case of systems working at 36 V
24 V , in case of systems working at 48V
In case of minimum battery voltage alarm, follow these steps:
