DESCRIPTION
Before driving the relay coil, the controller
checks if the relay contacts are stuck.
The Lift Enable switch was closed during
power-up in platform mode.
The Lift Enable switch was closed for
more than seven seconds while the mast
and jib joysticks were centered.
The Mast Joystick was not centered at
power-up in platform mode.
The Jib Joystick was not centered at
power-up in platform mode.
N.O. and N.C. contacts show the same
electrical status for more than 1 second.

CHECK
• Check the N.O. contact of the voting relay (installed
on the interface board - ground console).
• Check the voting relay output for short to +Vbatt
condition : CR1(24), CR1(25), CR1(26) & CR1(28)
and the connected lines.
• Check connections between the voting relay and
the main contactor: CR19(1) & CR7(8)
• Check if the lift enable switch is obstructed or
jammed.
• Check lift enable switch output voltage : J1(18).
• Check if the lift enable switch is obstructed or
jammed.
• Check lift enable switch output voltage : J1(18).
• Release joystick and allow to center.
• Check if the joystick is obstructed or jammed.
• Proceed with a calibration.
• Check the joystick voltages : if the power is not cor-
rect, replace the board; if the output is not correct,
replace the joystick (refer to Section 8).
• Release joystick and allow to center.
• Check if the joystick is obstructed or jammed.
• Proceed with a calibration.
• Check the joystick voltages : if the power is not cor-
rect, replace the board; if the output is not correct,
replace the joystick (refer to Section 8).
If machine is NOT equipped with Gate Limit Switches :
• Check machine configuration with the analyser.
If the machine is equipped with Gate Limit Switch(es) :
• Check if the Gate limit switch(es) is (are) damaged;
• Check the limit switch(es) for proper (complete)
actuation
• Check the limit switch(es) wiring :
Gate(s) closed :
@ +Vbatt : CR32(A), CR32(B), CR33(A),
CR33(B).
@ -Vbatt : CR32(C), CR33(C).
CHECK
• Check if the concerned switch is damaged,
obstructed or jammed.
• Disconnect the membrane panel ribbon cable :
replace the membrane panel if DTC is no longer
present.
• Check the switch line voltage : J3(12), CR1(34) and
CR2(17).
