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 if the
target pressure is 145 psi or less, to target p7
psi if the target pressure is greater than 145, but less
than or equal to 175 psi, or target pr5 psi if the
target pressure is greater than 175 psi. If the remote
sensor is ’on’, the maximum automatic stop pressure
will always be target pr5 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 if the target pressure is 145 psi or less, to automatic
stop p7 psi if the target pressure is greater
than 145, but less than or equal to 175 psi, or automatic
stop pr5 psi if the target pressure is greater
than 175 psi. If the remote sensor is ’on’, the maximum
immediate stop pressure will always be automatic stop
pr5 psi.
Blowdown Mode
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.
Condensate Release
This is the number of seconds that the condensate
solenoid will be open (energized) when blowing out the
condensation.
Condensate Interval
This is the time interval between condensation
blowdowns
% savings compared to
This setpoint is to determine what Nirvana’s percent of
savings is compared to. The modes of operation for
comparing Nirvana 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.
Service Menu
For use by IR personnel only.
