ARMREST CARD
Concerning this session, in the “Condition for error detection” description, if not expressly specified, the
wording "logic unit" refers to the ARMREST BOARD
E1 PUMP INCORRECT START
Condition for error detection
Logic unit incorrect starting procedure.
- check if one of the potentiometers is activated before switching the key ON.
- verify using the console
Enter the TESTER function in the menu MAT. HANDLING and check the status of the potentiometers in
the rest condition
LIFTING SWITCH = OFF
TILTING SWITCH = OFF
SIDESHIFT SWITCH = OFF
IV WAY SWITCH = OFF
V WAY SWITCH = OFF
LIFTING POT = 2,5 ± 0,2 V
TILTING POT = 2,5 ± 0,2 V
SIDESHIFT POT = 2,5 ± 0,2 V
IV WAY POT = 2,5 ± 0,2 V
V WAY POT = 2,5 ± 0,2 V
Once identified the potentiometer with the different values proceed as follows:
• reverse the potentiometer with one other potentiometer on the board(fingertips version)
• exchange the lifting potentiometer with the sideshift potentiometer or the tilting potentiometer with the
4th way potentiometer (joystick version)
- If the alarm persists in the same position, replace the board.
If the problem appears on a different potentiometer (according to where the defective potentiometer has
been connected) replace the potentiometer
