Model 9600/9700 Swing-Reach ® Lift Truck
Section 6. Electrical Tests Analog Tests
Test A19 - LA Temp [LPA Temp]
Test A19 - LA Temp [LPA Temp] Lift Power Amplifier (LPA) temperature is displayed. While operating, the LPA continuously monitors its internal heatsink temperature. If the temperature gets too high, performance is reduced until the LPA cools down. •
Normal operation: ambient to 175°F (79°C)
•
At 185°F (85°C), speed is linearly reduced to 0 fpm at 239°F (115°C), when lift is disabled
•
Code 7F is displayed when temperature exceeds 203°F (95°C) or falls below –40°F (–40°C)
As lift is operated, the LPA temperature should increase evenly over time. If not, refer to Diagnosis and Repair.
Diagnosis and Repair Step
Action/ Meter Scale
1
Is LPA hot to touch?
2
Allow time to cool. Does code clear?
(+) Lead
N/A
(–) Lead

Expected Results
Step Passed
Hot to touch
Perform step 2
If not hot, replace LPA
Not hot to touch/no code
Return to service
Replace LPA if code does not clear
Step Failed
NOTE: For extreme operating conditions where trucks are subjected to repetitive lift/lower cycles, short runs, and/or repetitive plugging cycles without time for the amplifiers to cool, a cooling fan kit is available through the Parts Distribution Center. Refer to the parts manual.
