Page 1 – System Overview
Figure 97 : System overview
This is the factory default display after powering up the system.
Target Pressure Setpoint is indicated in the black box, which is always
centered on the gauge. This is the pressure that the compressor is trying to
maintain by adjusting the motor speed.
Automatic Stop Setpoint is indicated in the black box which is always right
of center on the gauge. When the compressor reaches this setpoint the
compressor will unload and stop once the motor reaches minimum speed
and the compressor motor has been running for at least 2 minutes.
Package Discharge Pressure is indicated by the large numbers centered
below the gauge and by the red arrow. This is the output pressure of the
compressor.
Pressure Unit of Measure is indicated below the Package Discharge
Pressure. This is selectable from the GENERAL SETTINGS folder.
Percent Capacity is indicated on the lower left side of the screen in numeric
and bar graph form. This is how much air the compressor is producing as a
percentage of its maximum capacity.
Airend Discharge Temperature is indicated by the numbers in the lower
right of the display. This is the temperature of the air/oil mixture at the
discharge of the compression module.
Temperature Unit of Measure is indicated to the right of the Airend
Discharge Temperature. This is selectable from the GENERAL SETTINGS folder.
Run Hours indicate the number of hours the compressor has been running.
NOTICE
The target pressure and automatic stop set points can be selected and
modi ed on this page. All other information on this page is read only.
Page 2 - Counters
Figure 98 : Counters
Hour Meters Indicate the hours that: the controller has been powered up,
and the compressor has been running.
Starts indicate the number of times a start is attempted on the compressor.
Date & Time is adjustable and con gurable in the GENERAL SETTINGS folder.

Pages 3 & 4 – Analog Inputs and Compressor Information
Figure 99 : Analog Inputs and Compressor Information
Any sensor that is not installed or is reporting a failure will show a [ - - ]
symbol.
NOTICE
All information on this page is read only.
The following analog inputs are displayed in this section.
Package Discharge Pressure – The pressure the compressor is delivering
to the plant
Sump Pressure – The compressor’s internal pressure at the sump tank.
Airend Discharge Temperature – The temperature of the air/oil mixture
at the discharge of the compression module.
After-cooler Discharge Pressure (integrated dryer units only)
– Pressure the compressor is delivering before upstream of the dryer
Separator Pressure Drop – The pressure drop across the separator
element
Dryer Run Status (Integrated dryer units only) – Checkbox that shows
whether the dryer is currently running (checked) or not (blank)
Additionally, the following compressor status readings are included in this
section:
Motor Speed – The current speed of the motor in rpm
Package kW – The current power being consumed by the package,
including the main and blower VSDs

Pages 1 and 2 Operator Settings
Figure 100 : Operator Settings
Target Pressure – The compressor will vary its speed in order to maintain a
package discharge pressure as close to this value as possible.
Range (in psi): 65 - 145 (non-TAS compressors)
: 65 – 138 (TAS Equipped Compressors)
