2.24 ELECTRICS 1. Inspect the display module for damage or loose mounting. 2. Inspect the sensor on the rear axle for loose attachment bolts. 3. Inspect the sensor on the rear axle for secure bonding and signs of corrosion at the bonded surface. 4. Inspect the wiring harness, that connects the system components together, look for cuts or other damage. System Check NOTE: Disregard any error indications displayed during the first 30 seconds after power up. 1. Turn the engine start switch to the ON position. All the indicators will be illuminated for two to three seconds and the audible alarm will sound. This indicates that the LSI is performing an internal self-check.
On completion of self-check all indicators except indicator (7) will be extinguished and the audible alarm will cease. NOTE: If self-check is performed with a load on the boom, more than one indicator will remain illuminated. 2. Refer to the appropriate load chart. Pick up a load that is heavy enough to tip the machine when the boom is fully extended and raise the coupler 150 mm (6 in.) above the ground. NOTE: Keep the coupler 150 mm (6 in.) above the ground. 3. Extend the boom in stages and observe the indicators on the display module. As the boom is extended indicators (8) through (13) on the display module must illuminate progressively. 4. Continue to extend the boom.
As the boom approaches the point of instability, amber indicators (14) and (15) must be illuminated and the audible alarm sounds at approximately half second intervals. 5. Continue to extend the boom. As the boom extends past the point of instability, red indicators (16) and (17) illuminate and the audible alarm sounds continuously. 6. Retract the boom.
