3) GATE IS NOT AUTO TILTING
AT GROUND LEVEL
3.1) Check Battery Power
a) Check the position of the B-13 Sensor on the inside of the passenger side lift arm
Sensor has to be in a horizontal position when gate is 8”-10” above ground
b) Check if the outer J-41 Plug is loose (color sequence = blue, black, brown)
3.2) Check adjustment of auto-tilt sensor B-13
a) Check voltage at J41 #(BLACK)(B-13) to Ground J-2 #(-) while platform is on ground
12V
b) Check voltage at J41 #(BLUE)(B-13) to Ground J-2 #(-) while platform is on ground
12V
No voltage on BLUE
Look for damaged spots or loose connection or B-13 is bad
c) Check voltage at J4 #14 to Ground J-2 #(-) while pushing the lowering button when gate is on
ground for opening up the release valve S2 at the tilt cylinder
d) Listen for clicking of the release valve at the tilt cylinder (connected to platform)
If valve is not clicking
check wire for damaged spots or loose connections
3.4) Check voltage supply to release valve on tilt cylinder
a.) Check voltage at J30 #4 to Ground J-2 #(-) for power supply of the control buttons
b) Check voltage at J30 #6(lower) to Ground J-2 #(-) for lowering signal by pushing down knob
Signal on J30 #6
control buttons are ok; if no signal
check for damaged wire or loose cables
to control buttons or damaged buttons
3.3) Check function of control buttons(J30) and hand control(J31)
M
Series
a) Check resettable Circuit Breaker on top of battery
Push Reset Tab back in, if popped out
b) Check fuse on top of battery (qty 1) and
at circuit board (qty 2) inside pump and motor box at mount frame
c) Start van and run engine in fast idle for charging the battery
if liftgate starts working, recharge battery
test battery and replace if necessary
d) Check power on board between J-11 #4 and J-2 (-) with voltmeter by pushing the
up-function knob and hold for 10 sec with gate in upper position(DEADHEAD GATE)
(above 10 Volt is necessary for proper use of liftgate)
less than 10 V; Jump #2 to #4
on J-11
voltage jumps more than 1volt, call Palfinger for assistance
****DO NOT LEAVE JUMPER ON J-11
– GATE MUST BE SHUT OFF WHEN NOT IN USE****
