114 FACTORY OVERRIDE
When the controller is first shipped, prior to initial calibration, it is configured in
a special “factory override” state. In this state, none of the normal shutdowns
or interlocks will occur – the MEWP can be freely raised/lowered and driven
irrespective of any calibration needs, tilt, etc.
IMPORTANT: Never use a machine in factory override. This state is ONLY
intended for use during manufacture! While factory override is active, the LED
rapidly flashes on/off.

FAULT: B+ STUD
VOLTAGE TOO HIGH
- CHECK LINE CONT! The voltage on the B+ stud of the controller (connected to an internal voltage
stabilization capacitor bank) is close to B+ when the line contactor is off.
Check the line contactor tips are not welded; check the power wiring for errors.
3/3
116
FAULT: B+ STUD
VOLTAGE TOO LOW!
The voltage on the B+ stud of the controller (connected to an internal voltage
stabilization capacitor bank) is too far from B+ when the line contactor is off
(a pre-charge circuit in the module normally applies a voltage to the capacitor
bank).
