Air Handling Unit Shakedown Testing

The following are the Air Handling Units shakedown testing list: CORRECT ANSWER ACCEPTED? REMARKS Yes No

1. With the AHU off at the Front End Personnel Computer (FEPC), at the Hand-Off-Auto Switch (H-O-A), and the toggle override switch in normal position verify that both the Discharge Control Damper (CD-1) and the Damper Position Switch (DS-1) is in the closed/off position.

Verified Closed/Off

2. Are all the required inputs and outputs available at the AHU Microprocessor Controller (verify the AHU Microprocessor Controller (MC) directory)?

Yes

3. Does the failure of DS-1 prevent the AHU from operating? Yes

4. With the H-O-A control switch in the Hand position does CD-1 fully open? Yes

4A. With the override toggle in manual (on) position and the unit control board un-plugged or in failure state does the Unit Operate in 100% cooling mode? Does the unit start, does the CD-1 fully open, does the cooling valve FCV-1 fully open?

Yes

5. Do the interlocks prevent the starting of the AHU? Yes

6. Does the AHU require a manual restart after the interlock has shut the unit down?

7. Does the adjustable Time Delay Relay operate as set? Yes

8. Does the Differential Pressure Sensor indicate the correct operating status of the AHU? Yes

10. Does the Heating Water Valve (FCV-2) open/close when commanded to do so? Yes

11. Do FCV-1 and FCV-2 respond to Temperature Sensor (TS-1)? Yes

12. With the AHU set to the off position at the FEPC, does CD-1 start to close as soon as the H-O-A is set to the off position?

Yes
