Part 1: User Level WSPC USER INTERFACE
27
Mode – displays the Operating Mode of each compressor in the sequence. The
mode is the manner in which the machine’s operation is being controlled. When
running and operating normally, a compressor’s operating mode will be either
“Manual” or “Automatic” as selected by the user. Other modes are “Stopped”
when the machine’s operation has been stopped and “Faulted” when a fault has
occurred.
Hours – displays the sequence hours of a particular compressor. Sequence
hours are the number of hours set for a machine to run in sequence. This
parameter can be adjusted at the Adjustments Display to assign the compressor
to run in a specific order in the sequence system. When the operating mode is
set to Automatic, the machine with the lowest number of sequence hours will be
the next to start and the machine with the highest number of sequence hours will
be the next to stop.
PSI – displays the output pressure of the related compressor. This may be
displayed as BAR or Kpa depending on user profile preferences. This
measurement is taken at the P2 pressure transducer of the compressor and may
be a different value than the overall system pressure.
ACFM – shows the capacity of the specific compressor. Capacity is the volume
of air in cubic feet per minute (cfm) being delivered by the compressor.
Remote – indicates whether the compressor operation is being controlled
remotely (including sequencing control) or by the local controller only.
Service – displays “Yes” when the compressor is in need of service. This
indication is accompanied by either a service reminder or warning message to
inform the user of the nature of the service required.
Refer to the WS Controller Sequencing and Protocol Manual for details on
operating compressors in sequence.
3.8 ADJUSTMENTS DISPLAY
Both the compressor control parameters and sequencing parameters can be
edited at the Adjustments display of the WSPC User Interface. See Figure 3.12.
At this display the user can view the current settings of the machine control
parameters and make adjustments as necessary. Changes to the control
parameters will be reflected at the WS Controller located on the compressor.
