Platform Controller
(See Figure 3-2. & 3-3.)
The platform controller contains all the controls necessary
to operate the lift from the platform.
The following is a description of each function.
1. BATTERY VOLTAGE / FAULT CODE LED INDICA-
TORS.
The LED strip (green when lit) running between the
pad buttons on the controller pad indicates the bat-
tery voltage level when the machine is powered-up.
The graduated LED strip indicates batteries at FULL
CHARGE (25 volts) when lit all the way to the top (F),
and a LOW CHARGE (18 volts) at bottom (E) when
one or two LEDs are illuminated.
NOTE: When voltage drops below 16.5 volts an error code
is indicated, and the batteries will require a recharge.
This LED strip also acts as a fault code indicator to
help diagnose problems with the machines’ electri-
cal system. (See Service Manual Troubleshooting,
for information about reading fault codes).
2. FUNCTION ENABLE SWITCH ( OLD STYLE) (Fig. 3-2)
This switch must be pressed before any of the plat-
form or joystick drive functions can be operated.
Once activated, the operator has approximately
three seconds to activate any of the control func-
tions.
