2) GATE IS NOT LOWERING DOWN
2.1) Check Battery Power
2.2) Check for short in optional equipment
a) Check voltage between Ground J-2 #(-) to J4 #15 while pushing the lowering knob for opening
the release valve at the lift cylinder. No voltage
check for bad knob or loose wire to control knobs
b) Listen for clicking of the release valve at the lift cylinder (connected to lift arm)
If valve is not clicking
check wire for damaged spots or loose connections
2.3) Check voltage supply to release valve on lift cylinder
a) Check Voltage at J1 #12 and Ground J-2 #(-) while pushing knob to engage the shift valve S5 at
the pump and motor inside box at main frame underneath van.
b) Override the shift valve by pushing in at the cab of the shift valve while pushing the down knob
Gate will lower down
check the valve and look for damaged wire or loose connections
2.4) Gate is lowering down very slowly
S5 at motor not engaged
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 stored 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****
a) Unplug J-3(foot control), J-41(B-13, B16,
jump J-11 #4 to J-41 #GN
) and J-31(Hand control)
Keep the 3 connectors unplugged (gate will operate without plugs connected, loose auto tilt)
b) Unplug J-1 (Main power), wait 10 seconds and plug J-1 back to the board (Reset the board)
c) Plug each connector back, one at a time and check functions of gate after plugging in each
