Electrical Systems
Ensure that the batteries are charged . Turn the lift on & look at the LCD reading to check the
battery charge level. If the batteries are not charged, put them on charge before servicing the
equipment or connect a fresh set of batteries. If the charger indicator does not give any reading,
batteries can be tested “outside the system” with a load tester or, again, a fresh set of batteries
should be hooked up. An occasional battery problem is acid leaks at the vents. Sometimes a leak
shows up as corrosion of the battery leads.
Do a preliminary inspection of the circuit boards for burn marks or burns odours . A single or
series of components may have failed. The PCB will have to be replaced.
When an electrical problem seems to be the cause of the malfunction, it is important to first check
that all the wire harnesses are plugged in. Secondly, it is important to check all wire harnesses for
cuts and/or exposed wires. If this is found, the wire harness must be replaced.
2. The P-600 main board
The white power plug , second from left, connects the batteries to the circuit board. The circuit
board is connected to the main motor via the white plug on the right most side of the board. The
board and main motor plugs are shaped to prevent erroneous hook-up. The battery cables are
color-coded black and red to match the battery leads.
Check to see that the board, lift motor
and battery plugs are properly connected .
The white plug on the far PCB side, connects the charger to the PCB. The 16 pin connector ,
second from the left connects the LCD display to the PCB. The 4-pin white plug , next to the air
switches, connects the “slack tape” and “tape thickness” limit switches on the tape switch
assembly to the circuit board.
Check to see that the functionality plugs are properly connected
(when connecting a plug, it is easy to miss a prong) and that the wires do not pull out of the
functionality plugs (if a wire does pull out, it was either connected incompletely or connected
upside down).
