Causes
0 at MDI + Red LED : Battery below 5 % or
faulty variable speed drive
YV7 - YV9 power supply voltage and wire N°
3 ( B+ input, see if wires 100 and 3 are not
inverted)
Wires 6 not properly connected if all indicators
lit and 01 fault in the faulty variable speed
drive
Platform control box serial card or cable or
power supply plug (wire 58)
MDI wiring
MDI 7-wire wiring harnesses B5 / 38 - B5 / 39
- A3 / 40 - B1 / 41 - B12 / 51 - A7 / 52 - A6
Weighing card problem
Weighing card problem
EEPROM problem (Faulty variable speed
drive)
VMN low in idle mode or incoherent with the
PWM applied (Faulty variable speed drive)
General contactor latched (Auxiliary contact
switch on battery unit is open or faulty)
General contactor opened by the control PC
(Faulty battery isolation switch)
I = 0 Current always null during operation
(Faulty variable speed drive)
Current high in idle mode (Faulty variable
speed drive)
The capacitors do not start charging when the
key is turned off (Fuse 250 A / Engine
connections)
Variable speed drive temperature too high (>
75° Faulty variable speed drive)
Short circuit on the solenoid valves
Short circuit on the general contactor
Short circuit on the buzzer
Short-circuited general contactor driver
(Variable speed drive or contactor coil problem)
Short-circuited general contactor driver
(Variable speed drive or contactor coil problem)
(Wires 19 on terminal 9 are disconnected,
MAV on hydraulic unit)(Variable speed drive is
faulty if the relay is immediately latched)

Contact plug not properly connected to the
charger

Solutions
Check the cable connected between the YV7
coil (lowering) and the U2 variable speed drive
Check the connection of wire 26
Change the variable speed drive
Check the platform control box connection
Change the serial card
Contact closed upon start-up (Wire 28 or 31)
Contact closed upon start-up
Change the variable speed drive
Change the variable speed drive
Main SB1 contact switch always closed
(Change SB1)
Change the variable speed drive
Change the variable speed drive
Check the pump and its cable
Change the variable speed drive
Check the pump and its cable
Check the connection between the pump and
the variable speed drive
Check the main 300 A fuse
Check the variable speed drive's internal
resistance between P and B - (< 65 KOhms)
Change the variable speed drive
Check the line and the solenoid valve coil
Check the coil on the main relay
Check the buzzer
Check the relay coil (Cable or coil is cut)
Check the relay coil (Circuit and coil are
operational)
Check the YV2 and the 19 wire (Variable
speed drive starts immediately; line and coil
are operational)
Check the YV2 and the 19 wire (Line and coil
are cut)
Check the RCH charger contact switch
(Perform a shunt as a test)
