PATENTS PENDING
OCCUPIED:
There may be a load or occupant on the platform when the Controller (FIG. 72-1) looks for
a pressure reading that indicates an occupant on the platform (50+ lbs).
Corrective action:
1. Remove occupant or load from the platform.
2. If there is no occupant or load, go to diagnostic mode on the Controller (see DI-
AGNOSTICS) and check the hydraulic system pressure reading (PSI). It should
be between 170PSI to 230PSI. If reading is not in the range, change the Pressure
Transducer.
3. If the Controller (FIG. 72-1) still reads “OCCUPIED”, the platform occupied pressure
setting must be changed in the Controller or the Controller must be changed.
PSI SEN:
The Pressure Transducer is reading outside of the acceptable range of hydraulic system
pressure (PSI) for the function that Lift is performing.
Corrective action:
1. Check for disconnected or damaged Pressure Transducer wiring.
2. If wiring is okay, replace Pressure Transducer
LOW BAT:
Battery is below 12.2 volts. Controller allows the Lift to operate until battery voltage goes
below 12.0 volts.
Corrective action:
1. Start the vehicle to charge battery.
2. If that does not help, check if the battery is bad.
3. If the battery is OK, check to see if it is charging.
4. If battery is not charging, make sure the power cable and ground cable are in good
condition, and the connections on both ends are clean and tight.
CHRG BAT:
This reading appears when the platform is being raised or lowered and the battery is below
12.0 volts. The Controller will only allow the platform to be raised, folded, and stowed until
battery is re-charged.
Corrective action:
1. Start the vehicle to charge battery.
2. If that does not help, check if the battery is bad.
3. If the battery is okay, check to see if it is charging.
4. If battery is not charging, make sure the power cable and ground cable are in good
condition, and the connections on both ends are clean and tight.
