Causes
The general contactor driver does not close
(Contactor coil problem)
The general contactor driver does not close
(Variable speed drive problem)
Accelerator is high in idle mode (Faulty
joystick). Check the potentiometer powered in
51 / 52, output at 39
Accelerator is high in idle mode (Faulty
joystick). Check the potentiometer powered in
51 / 52, output at 39
Erroneous start-up sequence (Joystick
connection)
Double operation request (serial card or
joystick)
YV6 coil faulty or not properly connected
(wires 25/7, theoretical resistance: 75 Ohms)
YV6 coil faulty or not properly connected
(inversion of wires 5 and 27 on terminals 18
and 18)
The version (standard or Europe) is not
correct. The 2 VERSION and OK FOR
VERSION parameters are different
Drivers 2KO SIC Problem with small wiring
harness between MDI and the ground control
box.
The control PC does not respond correctly to
the SIEMENS PC (faulty variable speed
drive)If the horn is weak, change the coil's
general contactor at CC
Pressure switch alarm
The platform is at maximum height
Maximum current during braking or if the
platform is in drive mode
Difference between the variable speed drive
and MDI engine hour meters
Faulty chassis emergency stop auxiliary
contact switch
Request for programmed maintenance

Solutions
Check the relay coil SB1 (Faulty coil)
Check the relay coil SB1 (Coil is operational)
Check the joystick SM1. .
Check the voltage between wires 51 and 52
(potentiometer setpoint)Faulty serial card
Check the joystick SM1. Faulty joystick.
Check the joystick SM1. Faulty joystick.
Check coil YV6
Adjustment problem (console). Console
programming.
Check the short-circuit between the ground
control box earth and the SA2 switch in the
control box
Change the variable speed drive
Weighing card overload (cable 28 at 0V)Input
voltage at J4.6 = 0V
Faulty weighing card
SQ3 contactor contact switch open (Normal if
the platform is actually at maximum height)
High-level current at the input coming from the
pump (check the pressure and the pump for
current and isolation). Check the brakes
