Overheat; Brush Wear; Maximum Vehicle Speed Control (Suo #7); Output Power Control During Braking - Mitsubishi FB18KT Service Manual

Overheat

(1) Drive motor overheat (Error codes E0, E1)
The output limit control is provided only for drive
motors due to the thermal mode of the powering
characteristic. See page 1-7.
(2) Pump motor overheat (Error code E2)
In the cargo chopper model, the output duty
reduces by 50% in lifting and attachment
operations.
(3) Controller overheat (Error code E3)
The output limit control is provided for drive
motors due to the thermal mode. See page 1-7.
In the cargo chopper model, the output duty
reduces by 50% in lifting and attachment
operations.

Brush Wear

(1) Drive motor brush wear (Error codes E4, E5)
The output limit control is provided only for drive
motors due to the brush mode (same as thermal
mode) of the powering characteristic. See page 1-7.
(2) Pump motor brush wear (Error code E6)
In the cargo chopper model, the output duty
reduces by 50% in lifting and attachment
operations.
Maximum Vehicle Speed Control (SUO
#7)
The setup option setting limits the maximum vehicle
speed.

Output Power Control During Braking

The maximum current is controlled when the service
brake or parking brake is applied.
(1) Service brake — Maximum shunt current: 15 A,
maximum armature current: 125 A
(2) Parking brake — Maximum shunt current: 15 A,
maximum armature current: 125 A
(3) Normal — Maximum shunt current: 40 A,
maximum armature current: 250 A

Chat Timer (SUO #24)

• When the following conditions remain for the time
duration set by SUO #24, the line contactor turns
OFF.
Acceleration: 0
Direction lever: Neutral
Lift, tilt and attachment levers: OFF
Steering: Not operated
• Operating any of the above resets the line contactor.

Seat Switch Timer (SUO #25)

• When the operator leaves the seat for the time
duration set by SUO #25, the line contactor turns
OFF. When the power switch is turned on without
the operator sitting on the seat, the line contactor
turns OFF and the "E" indication flashes on the
display unit.
• With acceleration at 0, direction lever in neutral and
hydraulic levers OFF, turning on the seat switch
resets the line contactor.
Malfunction Detection
(Run Time Diagnosis)
If a malfunction is detected, the LED flashes and the
error code is indicated on the display unit. The
corresponding fail-safe function is also activated at the
same time. Refer to the malfunction detection and
main circuit errors tables.
