A setpoint’s value can be changed by first highlighting the item and its value
and pressing the SELECT button to highlight just the value. When the value
line is highlighted by itself, the value can be adjusted using the up and down
arrow buttons. The CANCEL and SET buttons appear at this time. Press the
SET button to enter the new value or press the CANCEL button to return the
value of the setpoint prior to using the arrows. The displayed value will flash
twice to indicate that it has been entered into the setpoint and the pair of
setpoint item and value display lines will again be highlighted together.
Operator setpoints can be exited by pressing the STATUS or MAIN MENU
buttons. If no buttons are pressed within 0 seconds, the display will return
to the CURRENT STATUS screen.
Target Pressure
The compressor will try to operate at this pressure setting. The target
pressure ranges and step sizes for each compressor of measure are listed in
the table below.
Table 4: Target Pressure Ranges and Step Sizes
Unit Min Max (1S / 2S) Step
PSI 65 145 1
BAR 4.4 10 0.1
kPa 440 1000 10
KGCM2 4.5 10.2 0.1
Automatic Stop Pressure
The compressor will stop once the system pressure rises to this pressure
and the compressor is operating at the minimum speed. The range for this
setpoint will be the target p1 to target p10 psi.
Immediate Stop Pressure
The compressor will stop if the system pressure rises to this pressure. The
range for this setpoint will be the automatic stop pressure to automatic stop
p10 psi.
Blowdown Mode
Two stage compressors will always blowdown when signalled to stop.
If this mode is selected to ON, the compressor will open the blowdown
valve anytime that it stops. This will vent pressure from the airend and
the separator tank. If this mode is selected to OFF, the blowdown valve
will remain closed when the compressor stops due to an automatic stop.
Blowdown mode is set on at all times for two stage models. Blowdown mode
will be shown as ”Not Installed” at the controller display.
% Savings Compared To
This setpoint is to determine what VSD’s percent of savings is compared to.
The modes of operation for comparing VSD to are modulation, online/offline,
and geometry. The percent savings value is displayed by the status message,
“% energy savings”.
Energy Rate
The energy cost and the energy savings items on the ENERGY STATUS screen
will use this value for their calculations. It is intended to be a monetary value
representing the user’s power cost per kilowatt hour.
Reset Averaging
When this setpoint is selected and the SET button is pressed, the items on
the ENERGY STATUS screen will be reset, and the date the reset occurred will
be displayed in this setpoint. This selects the beginning of the time period
over which the ENERGY STATUS information will be calculated. Note that the
“Lifetime Energy Savings” item will not be reset.
