Section III
Vehicle/Engine Requirements and Expectations
Life expectation (in hours or miles): _________________________________
Duty Cycle expectation (percent time compressor operates loaded):
5% to 25%
25% to 35%
greater
than
35%
Recommended
Test
Procedure:
Install a pressure switch (60 - 90 psi) in the governor signal line. Record the switch voltage
or continuity during vehicle operation. The duty cycle is the quotient of the compressor
loaded time (low pressure in the signal line) and the total time. The total time of the test
should reflect a typical operation cycle of the vehicle.
Was duty cycle measured? NO
YES
Measured value: _____________
Installation
angles:
Engine installation angle: _____________________________________
Compressor rotated angle: _____________________________________
Gradability (vehicle operation on slope):
Side: _______________________________________________________
For/Aft:
____________________________________________________
Percent of time operated on inclines? _____________________________
Compressor delivery/system pressure: _________________________________
Engine rated speed: _______________________________
Air compressor drive ratio: _________________________
