    Nursing administration 1308E

    Complaints of too much air flow in nursing administration 1308E.  Area is served off of VMA 27-10.  Cfm setpoint was at over 3000.  Metastat is in room 1308-D, which has lots of computers in it.  Put override on vma 27-10 at 1500, also found d/a temp was 70 degrees on all boxes.  Checked ahu, chilled water valve not opening.  Put cooling valve controller in manual, closed butterfly halway to control d/a temp a bit warmer.   AHU is offline on Metasys due to construction.


    Update:  On Saturday Fred took care of Metasys issue on ahu 27-10( see post below).  Cooling valve now back in auto, override taken off of VMA 27-10.

    AC27-10 will be running stand alone (not on the network). We may reconnect the N2 buss next week…or not. I don’t expect any problems.

    Sorry,… the cooling valve got locked out due to an unreliable input. I added a temperature sensor to the outside air input, adjusted DAT reset & cooling lockout setpoints.

    E-5012 AC 23-9 Supply Air VSD Replacement

    A replacement VSD (Danfoss Graham $ 2,772-) has been ordered for AC 23-9’s supply air.  Yesterday after the Gen Test the existing Square-D VSD did not survive.  Currently the fan is running at 100% capacity (existing VSD is completely bypassed) .  One of the end doors is intentionally propped open to relieve some of the system pressure.  Refer to req. # 7769911 for the replacement VSD status.
