Sullair WSPC - Clear Recent Data

Part 1: User Level WSPC USER INTERFACE
47
Power % shows the amount of power being used to operate the VSD
compressor expressed as a percentage of the compressor’s estimated usage
when operating at full capacity. The “Current” power data is updated frequently
and shows the instantaneous power usage rates. “Recent” shows the recent
power usage average, and lifetime shows the average power usage since the
machine was commissioned.
Hours indicates the amount of time (in hours and minutes) that the machine has
been operated since the Clear Recent Data button was clicked for Recent and
since the machine was commissioned for Lifetime.
Total Delivery indicates the estimated total amount of air delivered since the last
reset for Recent data and since the machine was commissioned for Lifetime
data; measured in thousands of cubic feet (KCF).
Total Energy indicates the estimated total electrical energy consumption since
the last reset for Recent data and since the machine was commissioned for
Lifetime data; measured in Kilowatt-Hours (KWH).
Total Cost indicates the cost for the electrical energy since the last reset for
Recent data and since the machine was commissioned for Lifetime data;
calculated as dollars (or other units of currency).
Savings vs Load/Unload shows the estimated additional cost to deliver the
same quantity of air using load/unload compressor control since the last reset for
Recent data and since the machine was commissioned for Lifetime data;
calculated as Dollars. This value is calculated using the Compressed Air
Challenge curve for Load/Unload.
Savings vs Inlet Mod. shows the estimated additional cost to deliver the same
quantity of air using inlet modulation compressor control since the last reset for
Recent data and since the machine was commissioned for Lifetime data;
calculated as Dollars. This value is calculated using the Compressed Air
Challenge curve for Inlet Modulation.
Savings vs Variable Displacement shows the estimated additional cost to
deliver the same quantity of air using variable displacement compressor control
since the last reset for Recent data and since the machine was commissioned for
Lifetime data; calculated as Dollars. This value is calculated using the
Compressed Air Challenge curve for Variable Displacement.
Refer to the WS Controller Instruction Manual for descriptions of VSD functions
and handling of warning and fault messages.
5.4 CLEAR RECENT DATA
The Recent data column displays average and total values since the date of the
last reset. Recent data history may be reset to zero (like a trip odometer in a car)
by clicking the Clear Recent Data button at the bottom of the VSD Performance
box. A few seconds after the button is pressed, all values in the Recent columns
of the VSD Performance group and the Delivery History window will be set to
