9.0 OPERATING INSTRUCTIONS

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 pressure+1 to target pressure+10 psi if the target pressure is 145 psi or less, to target pressure+7 psi if the target pressure is greater than 145, but less than or equal to 175 psi, or target pressure +5 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 pressure +5 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 pressure+10 psi if the target pressure is 145 psi or less, to automatic stop pressure+7 psi if the target pressure is greater than 145, but less than or equal to 175 psi, or automatic stop pressure +5 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 pressure +5 psi.

Blowdown Mode

2 stage compressors will always blowdown when signaled 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 2 stage models. Blowdown mode will be shown as ”Not Installed” at the controller display.

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.
