45 Platform
Level
Toggle
Switch
27 Active
at
startup
Toggle switch input
was detected as
HIGH at start-up.
Platform Level Up or
Down functions may
not operate,
depending on which
direction the switch
fault occurred.
*Verify with a voltmeter that the
Platform Level Up/Down Toggle
Switch (TS9) is operating properly.
* C14PLU (OR, PCON J17-2) should
be 0 V with the switch OFF and 12 V
with the switch held in the UP position.
* C15PLD (OR/BK, PCON J17-3)
should be 0 V with the switch OFF and
12 V with the switch held in the DOWN
position.
*Cycle power to allow the machine to
re-test the fault.
46 Platform
Rotate CW
Coil
11 Shorted
to
supply
voltage
PCON detected that
V17PRL circuit is
shorted to 12 V or
GND.
Platform Rotate CW
function will not
operate.
* With a voltmeter, measure Y70.
Proper resistance should be between
5 - 60 ohms. Replace Y70 if resistance
is outside of those values.
* Verify wiring for V17PRL (GR, PCON
J12-5) and check for open or short
circuits.
47 Platform
Rotate
CCW Coil
11 Shorted
to
supply
voltage
PCON detected that
V18PRR circuit is
shorted to 12 V or
GND.
Platform Rotate CCW
function will not
operate.
* With a voltmeter, measure Y71.
Proper resistance should be between
5 - 60 ohms. Replace Y71 if resistance
is outside of those values.
* Verify wiring for V18PRR (GR/BK,
PCON J12-4) and check for open or
short circuits.
51 Drive
Joystick
11 Shorted
to
supply
voltage
Circuit C160DRV is
above 4.5 V.
Drive Forward and
Reverse functions will
not operate.
* Leave joystick in neutral position and
cycle power.
* If fault persists, with a voltmeter
check that C160DRV (WH/RD, PCON
J18-10) is at 2. 5V +/- 0.2 V at startup
and does not go above 4.5 V or below
0.5 V when fully stroked in each
direction.
* Replace joystick if voltage check
fails.
27 Active
at
startup
Circuit C160DRV
voltage was not
within the startup
voltage range of 2.5
V +/- 0.2 V.
