Device Calibration Checks. The actuators or devices listed below checked rorcaIibration. This is a spot <br /> <br />check on a sample of the calibrations done during field verification checklist and startup. <br /> <br />"In calibration" means observing readoul in the BAS and going 10 the actualor or controlled device and verifying that the BAS <br />reading is correct. For items oul of calibration or adjustment, fIX now if easy, via an offset in the BAS, or a mechanical fIX. <br /> <br />Device or Actuator & Location 1st Site Final BAS Pass <br /> Procedure I State BAS Value Observation Reading Y/N <br />DX cooling stages control . <br />Stage I I.

Command damper closed and verifY that damper is shul and BAS reads shut. 2. Do the same, commanding damper fully open. <br />***Yill; Procedure 1. Verifji that the minimum and maximum speeds of the variable frequeucy drives match the building automation <br />system reading. . <br /> <br />Notes: Testing of AHU #3 was performed using HVACPro. <br />1. Main computer is not setup for alarms. U.N. T. controAer is not programmed properly, pressure wiN aJways read O. <br />2. Unable to lest because of outside air temperature. <br />3. Supply fan status does not_k. status continually shows on. <br />4. Intine fan 5, (IF-S) has no points on controller. Fan is only controNed by local switch in macho room. <br />5. Fan status is not wi"ed to proper point on controller. <br />6. C0ntr0lIer is not programmed for warm up mode. <br />7. Economizer ~ is locked out on outside air temperature set poinl <br />8. OJ<. cooling is never locked out Outside air temperature is not being written to controller and set point fo< lockout is at 20". <br />9. Low Omit pro\ec\ion device is wired to the supply fan status point. No alann is generated. <br />10. Opening contacts dido' shut down unl. No alarm is generated. <br />11. Main computer is not setup for alarms. U.N.T. controller is not programmed properly. pressure will always read O.Finer status is <br />not on computer. <br />12 No motorized rer.., damper installed. <br />13. Radiation valve is conIJolIed by separate zone set point not from sflder on tllennoslal. <br /> <br />File: AHU3_FinaIReport.doc <br /> <br />Page 3 of 6 <br />
