00:00:00,000 --> 00:00:05,875
To check the air compressor loading operation, the air compressor must be loaded manually.

2
00:00:05,875 --> 00:00:12,083
To manually load the air compressor, remove the governor test probe and leave the CMV unlatched.

3
00:00:12,083 --> 00:00:17,375
<b>Warning:</b> Do not allow the air compressor to operate in this mode unattended.

4
00:00:17,375 --> 00:00:24,667
The ARPS will sense the low air pressure and the control system will continuously cause the air compressor to load.

5
00:00:24,667 --> 00:00:35,208
The J1 safety valve will open when pressure reaches 150 psi, but no other device will keep the main reservoir pressure within safe limits.

6
00:00:35,208 --> 00:00:40,292
When the governor test probe is removed, the line to the ARPS is vented.

7
00:00:40,292 --> 00:00:51,208
The ARPS will indicate lower air pressure, the control system will cause the motor to start, and two seconds later, the CMV will de-energize, exhausting air.

8
00:00:51,208 --> 00:01:00,917
This action will cause the air compressor to load (i.e., the intake valves will close and the compressor will pump air, thus building air pressure).

9
00:01:00,917 --> 00:01:05,000
Ensure that the test probe is re-installed when testing is complete.
