00:00:00,000 --> 00:00:06,042
To check the air compressor unloading operation, the air compressor must be unloaded manually.

2
00:00:06,042 --> 00:00:13,375
To manually unload the air compressor, remove the governor test probe, allowing the line to the ARPS to be vented.

3
00:00:13,375 --> 00:00:17,958
Then, latch (that is, energize) the CMV.

4
00:00:17,958 --> 00:00:30,417
With the CMV energized, pressure acts on the compressor unloader valves, and the unloader valves physically force the compressor intake valves to remain open, preventing the compressor from building pressure.

5
00:00:30,417 --> 00:00:33,583
Return the CMV to the unlatched position.

6
00:00:33,583 --> 00:00:37,833
Fit the test probe before returning the locomotive to service.
