NOTE: At this point, the yellow warning light on the display panel will be lit and will stay on throughout the run test. After each successful step, the red alarm light will blink once.

11.The control module will now check if there is input from BYPAS (50XJ), DHS, FSD, SAT, DSP, and CSMUX.

If the control does not receive open/open/closed/ in range/in range/in range, the red alarm LED will go on and the test will stop.

If the inputs are OK, the red alarm LED blinks once and the test continues.

12.Next, the control forces the Supply Fan (SF) and all of the Compressors (COMP) off, and waits 15 seconds.

For the 50XJ unit, if the REMOTE LED and AUTO LED on the VFD display are on, the red LED blinks once and the test continues.

NOTE: For the 50XJ unit, if the controller is config- ured with a water Economizer, the delay is 2 min. and both valves are commanded to 0%. Both water valves will close.

13.The control forces SF on and SPEED to 20 percent and then waits 30 seconds.

If the VFD display shows “10.6 Hz,” the Remote and Auto LEDs blink, and the fan goes on, then the red LED on the control module blinks once and the test continues.

NOTE: For the 50XJ unit, if the controller is config- ured with a water Economizer the delay is 2 min. and Econo valve is commanded to 100%. The economizer valve will open and the RVS/HD (reverse/head pressure) valve will remain closed.

14.The control forces SF on and SPEED to 35 percent and then waits 30 seconds.

If the VFD display shows “20.0 Hz,” the Remote and Auto LEDs blink, and the fan goes on, then the red LED on the control module blinks once and the test continues.

NOTE: For the 50XJ unit, if the controller is configured with a water Economizer the delay is 2 min. and RVS/ HD valve is commanded to 100%. The economizer valve is commanded to 0% and the RVS/HD valve will open.

15.The control forces SF off then waits 15 seconds.

If the VFD display shows “Off,” the Remote and Auto LEDs are off, and the fan goes off, then the red LED on the control module blinks once and the test continues.

NOTE: For the 50XJ unit, if the controller is configured with a water Economizer both valves are commanded to 0%. The economizer valve and RVS/HD will close.

NOTE: For the 50BV unit, the steps below (16-24) will be completed for the number of compressors configured.

16.The control forces CMP1 (compressor 1) on then waits 5 seconds.

If CSMUX is not in range the red LED will go on and the test will stop.

If CSMUX is in range, the red LED blinks once and the test continues.

17.The control forces CMP1 off.

18.The control forces CMP2 (compressor 2) on then waits 5 seconds.

If CSMUX is not in range the red LED will go on and the test will stop.

If CSMUX is in range, the red LED blinks once and the test continues.

19.The control forces CMP2 off.

20.The control forces CMP3 (compressor 3) on, if config- ured, then waits 5 seconds.

If CSMUX is not in range the red LED will go on and the test will stop.

If CSMUX is in range, the red LED blinks once and the test continues.

21.The control forces CMP3 off.
