GROUP 12 MONITORING SYSTEM
1. OUTLINE
Monitoring system consists of the monitor part and switch part.
The monitor part gives warnings when any abnormality occurs in the machine and informs thecondition of the machine.
Various select switches are built into the monitor panel, which act as the control portion of the machine
control system.

CLUSTER CHECK PROCEDURE
Start key : ON
Check monitor initial 5 seconds
All lamps light up.
Buzzer sound.
Check monitor after 5 seconds : Indicate cluster version and machine condition
Cluster program version :1.00 Indicates program version1.00for 5 seconds.
Tachometer : 0rpm
Fuel gauge : All light up below appropriate level
Hydraulic temperature : All light up below appropriate level
Engine coolant temperature gauge : All light up below appropriate level
Warning lamp
During start key ON the engine oil pressure lamp and battery charging lamp go on, but it is not
abnormal.
When engine coolant temperature below 30C, the warming up lamp lights up.
Indicating lamp state
Work mode selection : General work
Power mode selection : S mode
User mode selection : No LED ON
Auto decel LED : ON
Travel speed pilot lamp : Low(Turttle)
Start of engine
Check machine condition
Tachometer indicates at present rpm
Gauge and warning lamp : Indicate at present condition.
When normal condition : All warning lamp OFF
Work mode selection : General work
Power mode selection : S mode
User mode selection : No LED ON
Auto decel LED : ON
Travel speed pilot lamp : Low(Turttle)
When warming up operation
Warming up lamp : ON
10 seconds after engine started, engine speed increases to 1000rpm(Auto decel LED : ON)
Others same as above
When abnormal condition
The lamp lights up and the buzzer sounds.
If BUZZER STOP switch is pressed, buzzer sound is canceled but the lamp light up until
normal condition.

4. CLUSTER FUNCTION
This gauge indicates the amount of fuel in the fuel tank.
Fill the fuel when the 1st step or fuel icon blinks in red.
If the gauge illuminates the 1st step or fuel icon blinks in
red even though the machine is on the normal condition,
check the electric device as that can be caused by the poor
connection of electricity or sensor.
1st step
Fuel level gauge
This gauge indicates the temperature of hydraulic oil in 12 step
gauge.
1st step : Below 30C(86F)
2nd~10th step : 30-105C(86-221F)
11th~12th step : Above 105C(221F)
The gauge between 2nd and 10th steps illuminates when
operating.
Keep idling engine at low speed until the gauge between 2nd
and 10th steps illuminates, before operation of machine.When the gauge of 11th and 12th steps illuminates, reduce the
load on the system. If the gauge stays in the 11th~12th steps,
stop the machine and check the cause of the problem.

1 SPECIFICATION
Operating voltage : 244V
Power : 20050WCurrent : 15A
2 OPERATION
The current of fuel warmer system is automatically
controlled without thermostat according to fuel
temperature.
At the first state, the 15A current flows to the fuel
warmer and engine may be started in 1~2
minutes.
If the fuel starts to flow, ceramic-disk in the fuelwarmer heater senses the fuel temperature to
reduce the current as low as 1.5A.
So, fuel is protected from overheating by this
mechanism.
