Electrical System
4. Leave the machine undisturbed for a minimum of 2
hours before moving. DO NOT lift any load for a
minimum of 12 hours.
5. The transducer and area around it can be painted 2
hours after installation.
6. Plug the electrical connector into the sensor
assembly.
7. Connect the battery negative (-) cable to the battery
negative (-) terminal.
8. Close and secure the engine cover.
c. Load Moment Sensor Calibration
Calibration of the load moment sensor requires the
setting up of two reference points. 0% and 100% SWL.
During calibration the machine must be level, brakes off,
steering straight ahead and ignition turned on. Access to
the calibration mode requires the use of the magnetic
"key".
Acquiring the calibration mode
For the first calibration at installation:
When first installed and powered up, the display will show
error condition number 4 (red LED and 3rd green LED),
indicating that calibration is required. PRESS and hold
the TEST button, and place the magnet in position level
with and just to the right of the TEST button. The correct
position is indicated when the sounder stops and all LEDs
stay on. KEEP HOLDING THE TEST BUTTON AND
MAGNET IN PLACE until the display changes again to
show the red LED only. This indicates that the system is
now in calibrating mode, and waiting for the first
reference point.
RELEASE the TEST button and remove the magnet. The
display will emit short intermittent beeps to remind the
operator that calibration is in progress.
Note: If either the button or magnet is released too early
the display will revert to the uncalibrated condition
number 4.
THE SYSTEM ALLOWS FIVE MINUTES for each part of
the calibration procedure to be completed. If a part of the
calibration procedure is not completed within the five
minutes allowed, the system will automatically revert to
the uncalibrated error condition number 4.
IF THE IGNITION IS SWITCH OFF during first calibration
the system will remain in the uncalibrated condition.
For any subsequent calibration:
PRESS and hold the TEST button, and place the magnet
in position level with and just to the right of the TEST
button. The display will show all LEDs flashing and
sounder on. The correct position is indicated when the
sounder stops and all LEDs stay on.
Calibration Procedure:
1. Set 0%
ARRANGE the machine on level ground in the 0%
calibration position (boom is retracted, forks lowered
but not resting on the ground, and no load on the
forks.
PRESS the TEST button ONCE. The system will
give a single, short beep indicating that the 0% point
is set. The display will change to show the red and
amber LEDs lit (with continuing intermittent beeps),
indicating that the system is ready and waiting for
the 100% reference.
Note: If a long beep is emitted from the sounder during
calibration, this indicates a fault condition - see below.
2. Set 100%
PICK up the calibrated (maximum capacity) 100%
load and extend the boom to the pre-determined,
normal 100% point.
PRESS the TEST button ONCE to set the 100%
reference. The display will now change back to
normal operation, and show 100% (all green and
amber LEDs lit and flashing).
System calibration has now been completed. No
further action is required.
9.9.3 Back-up Alarm
The back-up alarm is located at the rear of the machine.
When the transmission shift control switch (transmission
control lever) is shifted to the (R) REVERSE position, the
back-up alarm will automatically sound.
Place the transmission control lever in (R) REVERSE to
test the back-up alarm. The back-up alarm must not
sound when the transmission control lever is in (N)
NEUTRAL or (F) FORWARD. Also, with the ignition key
switch in the RUN position, the back-up alarm will sound
when the transmission control lever is shifted into the (R)
REVERSE position.
a. Disassembly
DO NOT disassemble the back-up alarm. Replace a
defective or faulty alarm with a new part.
