1.2 GENERAL SAFETY RECOMMANDATIONS

Before operating the machine, always ensure that the machine complies with work safety regulations.

GENERAL

1. Safety decals with recommendations to prevent accidents are placed on the machine.

2. Before carrying out work, ensure that the weighing unit is turned off.

3. Portable telephones can have a harmful effect on the working of the weighing unit.

USE

Before connecting the weighing unit to the tractor:

- check that the electric plug is clean and free from dirt,

- check that the electric circuit is correct.

MAINTENANCE

1. Disconnect from the power source before any work is done on the electrical system.

Before any electric welding is carried out on a machine that is attached
to the tractor, disconnect the tractor alternator and battery. Connect
the earth lead as close as possible to the part to be welded. Never
connect the earth to the chassis if the hopper is to be welded. If this
advice is ignored, then irreparable damage can be caused to the sensors
which connect the hopper and chassis.

- Check the power supply voltage: this should be within the range 11 to 17 V olt s d.c.
Warning: the indicator does not accept a.c.

- Check the connection to the tractor.

- Check the power supply cable fuse (15 A).

- For machines equipped with an internal battery, check the 2 A fuse.

- If the fuse is faulty, replace it: fuse type 5x20 2A.

- If these checks fail to reveal any reason for the fault, replace the weighing unit (see the section on
“Fitting and removing the sensors and the unit”).

Fault: The screen displays the ‘BAT’ message.

- The tractor power supply voltage has dropped below 11 V.

- For machines equipped with an internal battery , recharge the battery (see the section “Option: internal
battery life”).

Fault: The weight is not correct.

Cause: If the indicator displays 0 when the machine is loaded, the machine has been declared as
empty when it is full: refer to the section on “Restoring the factory zero setting” in the user instructions.

- Check that the machine meets the specified operating conditions (see the section on “Operating
conditions”).

- Check the connections between the sensors and the circuit board and the condition of the wiring.

- Test the sensors (see 2.2.4) to check the condition of the board and each sensor.

- If the sensors are in working order, and the operating conditions are satisfactory, calibrate the unit
again (see 2.2.5 or 2.2.6).

Fault: The weight is not stable. The display varies while the tractor engine is off.

- Check that the machine meets the specified operating conditions (see the section on “Operating
conditions”).

- Check the connections between the sensors and the circuit board and the condition of the wiring.

- Test the sensors (see 2.2.4).

- Check that the power supply voltage is stable. If not, check that the power supply is correctly
connected to the tractor battery. If the connection is OK, check the tractor’s electrical installation.

- If the power supply voltage is stable, check the voltage stability of each sensor and change the
sensor concerned.

- If these checks fail to reveal any reason for the fault, replace the weighing unit (see section “Fitting
and removing the sensors and the unit”).

2.3 TROUBLESHOOTING

22

Fault: After moving, the indicator no longer displays the same value.

- Check that the machine meets the specified operating conditions (see the section on “Operating
conditions”).

- Check the connection of the sensors in the junction box and the condition of the wiring.

- Test the sensors (see 2.2.4).

- Check that the power supply voltage is stable. If not, check that the power supply is correctly
connected to the tractor battery. If the connection is OK, check the tractor’s electrical installation.

- If the power supply voltage is stable, check the voltage stability of each sensor.

- If these checks fail to reveal any reason for the fault, use the self-test sensor voltage display to note
the value of each sensor, then move the machine and note the new values of each sensor . The sum
of the voltages before and after moving should be the same.

- If they are different, there is a mechanical problem. Check again that the machine meets the specified
operating conditions (see the section on “Operating conditions”).

Fault: The indicator displays “

- - - - -” or “8 8 8 8 8”.

- Switch off your weighing unit and contact your approved Kuhn dealer to get your unit checked.

Fault: The message “

C E L L” appears on the screen.

- The indicator is signalling a sensor problem. Contact your approved Kuhn dealer to get the condition
of the sensor cables and connections and the working order of each sensor checked.

3.3 TROUBLESHOOTING

Fault: The weighing unit does not come on when the power is switched on

Cause: the indicator’s operating temperature range is -20 to +50°C

- Check that the temperature is not outside the operating limits.

No audible signal is heard

Cause: the indicator’s operating voltage is 12 Volts (maximum 17 Volts). It is protected by a 15A
fuse.

- Check that the +/- polarity is correct.

- Check the power supply voltage: this should be within the range 11 to 17 V olts d.c.

Warning: the indicator does not accept a.c.

- Check the connection to the tractor.

- Check the power supply cable fuse (15 A).

- For machines equipped with an internal battery, check the 2 A fuse.

- If the fuse is faulty, replace it: fuse type 5x20 2A.

The audible signal is heard

- Check the power supply voltage, this should be within the range 11 to 17 V olts d.c.

- For machines equipped with an internal battery, recharge the battery (see the section “Option:

internal battery life”).

- If the voltage is correct, adjust the display contrast as this may vary with temperature:

- for units made before April 1998, see adjustment on the board connection diagram, page 24

- for units made later than April 1998, adjust the contrast button on the front of the unit.
If these checks fail to reveal any reason for the fault, replace the weighing unit (see the section on

“Fitting and removing the sensors and the unit”).

Fault: The screen displays a ‘battery low’ message

This message is displayed in two situations:

1. The tractor power supply voltage has dropped below 11 V
For machines equipped with an internal battery , recharge the battery (see the section “Option:
internal battery life”).

2. There is a problem on the printed circuit board or a sensor (board and sensor monitoring)

In either case, run self-tests on the unit and sensors: see 3.2.3.1 “Testing the printed circuit voltages”
and “Displaying the sensor voltages”.

Fault: The weight is not correct

Cause: If the indicator displays 0 when the machine is loaded, the machine has been declared as
empty when it is full: refer to 3.2.2.3 (Confirmation of the tare).

- Check that the machine meets the specified operating conditions (see the section on “Operating
conditions”).

- Check the connections between the sensors and the printed circuit board and the condition of the
wiring.

- Run the self-tests on the unit and sensors: see 3.2.3.1 “Testing the printed circuit voltages” and
“Displaying the sensor voltages”.

- If the circuit board and sensors are all working properly and the operating conditions are correct,
carry out calibration as described in 3.2.2.2.

36

Fault: The weight is not stable. The display varies while the tractor engine is off.

- Check that the machine meets the specified operating conditions (see the section on “Operating
conditions”).

- Check the connections between the sensors and the circuit board and the condition of the wiring.

- Run the self-tests on the unit: see 3.2.3.1.

- Check that the power supply voltage is stable. If not, check that the power supply is correctly
connected to the tractor battery. If the connection is OK, check the tractor’s electrical installation.

- If the power supply voltage is stable, check the voltage stability of each sensor and change the
sensor concerned.

- If these checks fail to reveal any reason for the fault, replace the weighing unit (see the section on
“Fitting and removing the sensors and the unit”).

Fault: Horizontal stripes appear on the screen

Cause: The weighing unit has suffered an impact

- Replace the weighing unit.

Fault: The screen is not legible

Cause: Insufficient lighting - the screen is partially or totally blank.

- Use a voltmeter to check that the indicator supply voltage is 12 V.

- For machines equipped with an internal battery, recharge the battery (see the section “Option:
internal battery life”).

- If the voltage is correct, adjust the weighing unit contrast using the potentiometer located on the
circuit board (for units made before April 1998 - see the section on circuit board connections), or for
units made later than April 1998, adjust using the contrast button on the front of the unit.

- If it is not possible to adjust the unit satisfactorily, replace the weighing unit (see the section “Fitting
and removing the sensors and the unit”).

Fault: After moving, the indicator no longer displays the same value

- Check that the machine meets the specified operating conditions (see the section on “Operating
conditions”).

- Check the connections between the sensors and the circuit board and the condition of the wiring.

- Run the self-tests on the unit: see 3.2.3.1.

- Check that the power supply voltage is stable. If not, check that the power supply is correctly
connected to the tractor battery. If the connection is OK, check the tractor’s electrical installation.

- If the power supply voltage is stable, check the sensor excitation voltage and the voltage stability of
each sensor.

- If these checks fail to reveal any reason for the fault, use the self-test sensor voltage display to note
the value of each sensor, then move the machine and note the new values of each sensor. The
sum of the voltages before and after moving should be the same.

- If they are different, there is a mechanical problem. Check again that the machine meets the specified
operating conditions (see the section on “Operating conditions”).

37

Fault: The indicator displays ----

a) Immediately after answering YES or NO to the question “Is the machine empty?”
Cause 1: A sensor is faulty

- Carry out a self-test. If the sensors are correct, see Cause 2.
Cause 2: Calibration is not correct

- Repeat the calibration. See (3.2.2.2 “Calibration using a known weight”)
(3.2.3.1 to correct the standard values)

b) On the standard weighing unit, after unloading
Cause: The unloaded value is over 995 kg.

Recommendations

Before carrying out any maintenance or repair work or when attempting
to find the cause of a fault or malfunction, switch off the engine, lay the
machine on the ground, remove the key from the ignition and wait until
all moving parts have come to a complete standstill.

Before proceeding with maintenance work on a machine in the raised
position, prop it up with an appropriate support.

Before carrying out any work on the weighing unit, disconnect the
electrical circuit from the unit.

Never remove the front panel from the IND900 unit.

Check regularly that the weighing unit is watertight (seals, gland, front
panel sticker, etc.).

Check the condition of the power cables and sensors regularly
(protective sleeves flattened or cut) and change them if necessary.

WARNING

To carry out welding work on a machine, disconnect the electrical power
supply from the machine and the tractor (battery or alternator).

Connect the earth lead as close as possible to the part to be welded.
Never connect the earth to the chassis to weld the body and vice-versa.
If this advice is ignored, then irreparable damage can be caused to the
sensors linking the body to the chassis.

We strongly advise against the use of pressure washers. There is a
risk that moisture will penetrate inside the weighing unit and sensors.
