Testing System Voltage

The information center has the ability to allow you to view the system voltage without using a digital volt meter (DVM). The information center operates on a system voltage of 24 volts supplied by the two batteries located in the battery compartment. This will inform you of the condition of the batteries at initial power up of the information center This figure can be compared to the system voltage present on the guage display to decide if the problem exist with the batteries or the altenator. To test the system voltage do the following:

1 Turn the key switch to the on position, do not start the machine. 2 Advance to display field number 014 using the programming entry procedure listed previously. 3 Press the Program/Reset switch back to the center position. The system voltage will be displayed. 4Press the Program/Reset switch to the Reset position to exit the monitoring mode. 5 Turn the key switch to the off position.

Alarm Check

The alarm can be checked to make sure that it is operating correctly. To check the alarm: 1 Turn the key switch to the on position, do not start the machine. 2 Advance to display field number 015 using the programming entry procedure listed previously. The alarm will begin to sound intermittently. 3 Press the Program/Reset switch back to the center position. The display will read 00 and the alarm will sound while the information center checks to see that all systems are normal. If an error is detected the display will read 01. The alarm will still sound intermittently. 4 Press the Program/Reset switch to the Reset position to exit the monitoring mode. 5 Turn the key switch to the off position.

Coolant Level Check

The machine coolant level can be checked by using the information center. To check the machine coolant level: 1 Turn the key switch to the on position, do not start the machine. 2 Advance to display field number 016 using the programming entry procedure listed previously 3 Press the Program/Reset switch back to the center position. The display will read 00 if the coolant level is normal.

If the coolant level is low the machine will read 01 in the display. 4 Press the Program/Reset switch to the Reset position to exit the monitoring mode. 5 Turn the key switch to the off position.

Brake Pressure Switch Check

This will check the brake pressure switch to make sure that it is functioning properly. This same check will also show if the brake pressure indicator light is functioning. This test checks the wiring from the information center to the pressure switch. It does not check the wiring from the information center to the park brake pedal switch located on the brake pedal under the cab.

To check the brake pressure switch:

1 Start the machine and allow it to run for 30 seconds to make sure the accumulators are fully charged. 2 Turn the key switch to the on position, do not start the machine. 3 Advance to display field number 017 using the programming entry procedure listed previously. The brake pressure light will flash intermittently. 4 Press the Program/Reset switch back to the center position. You should see 01 in the display if the brake pressure is normal. 5 Cycle the brake pedal several (30 ñ 40) times. You should see the 01 change to a 00 in the display indicating that the pressure is below normal. 6 Press the Program/Reset switch to the Reset position to exit the monitoring mode. 7 Turn the key switch to the off position Up count Program

Secondary Steering Pressure Switch Check

This will check the secondary steering pressure switch to make sure that it is functioning properly. This same check will also show if that the secondary steering pressure indicator light is functioning. This check only applies to machines equipped with secondary steering. To check the secondary steering pressure switch:

1 Start the machine. 2 Advance to display field number 018 using the programming entry procedure listed previously. The secondary pressure light will flash intermittently. 3 Press the Program/Reset switch back to the center position. You should see a 01 in the display if the secondary steering is not activated. 4 Turn the key switch off and back on very quickly.

Park Brake Information Center Output Check

This will check the wiring from the information center to the park brake relay to make sure that it is functioning properly. This same check will also show if the park brake indicator light is functioning. This check does not check the wiring from the information center to the park brake switch located in the cab.

1 Start the machine. 2 Advance to display field number 019 using the programming entry procedure listed previously. The park brake light will flash intermittently. 3 Press the Program/Reset switch back to the center position. You should see a 00 in the display if the information center is not activating the park brake relay and the park brake is in the on position. 4 Turn the park brake switch in the cab to the off position, place or foot on the service brake and shift the FNR lever to either forward or reverse. You should see the display read 01 when the park brake releases. 5 Place the FNR lever back in neutral, place the park brake switch in the on position. 6 Press the Program/Reset switch to the Reset position to exit the monitoring mode. 7 Turn the key switch to the off position.

Pilot Lock-Out Information Output Check

This will check the wiring from the information center to the pilot lock-out relay to make sure that it is functioning properly. This same check will also show if the pilot lock-out indicator light is functioning. This check does not check the wiring from the information center to the pilot lock-out switch located in the cab.

1 Start the machine. 2 Advance to display field number 020 using the programming entry procedure listed previously. The pilot lock-out light will flash intermittently. 3 Press the Program/Reset switch back to the center position. You should see a 00 in the display if the information center is not activating the pilot lock-out relay and the pilot lock-out is in the off position. 4 Turn the pilot lock-out switch in the cab to the on position. You should see the display read 01 when the switch is flipped. 5 Press the Program/Reset switch to the Reset position to exit the monitoring mode. 6 Turn the key switch to the off position.
