(Battery Discharge Gauge)
10
SPJ Joysitck (NX/NX-LP)
The joystick information gauge and the Remote Programmer give indications of the types of fault
or error detected by the controller. When a fault is detected, the chair will stop and will not drive.
All of the BGD (Battery Gauge Display) lights on the information gauge will beging to flash. The
number of flashes idicates the nature of an abnormal condition. An error and a quick description
of the fault will begin to scroll across the Remote Programmer display.

The BGD (Battery Gauge Display) also serves as a system diagnostic device when a fault is
detected by the controller. A specific number of flashes of the last two red bars (up to eight (8)
flashes) will start to flash on and off to indicate the type of fault detected separated by a pause.
MPJ Joystick (EX & TT-EX)
During normal operation the active drive is displayed on the left half of the first line. The left half
of the second line is the BDG (Battery Discharge Guage). It provides information on the remain-
ing charge in the batteries. At full charge solid blocks fill in all five (5) segments between E
(Empty) and F (Full). As the battery becomes discharged, the farthest right segments will
progressively disappear a half bar at a time until no segments appear between E and F. At this
level the word RECHARGE will appear on the second line to indicate that the user should charge
the batteries as soon as possible.
The right half of the display is the Information Center. The Information Center displays current
data on the chair. If a fault is detected, the cause of the fault will scroll across the second line of
the display.
