Pages 6-7: Sensor Calibration
Figure 37: Sensor Calibration
Sensor calibration can only take place when the compressor is stopped.
There should be no pressure on a sensor when it is calibrated. Calibration
only needs to take place after a sensor is replaced, the controller is replaced,
or the operator suspects the sensor reading is in error. Calibrate a sensor by
selecting the checkbox beside the sensor name.
Each of the sensors listed below can be calibrated:
• Inlet Vacuum (1AVPT)
• Sump Pressure (APT)
• Package Discharge Pressure (4APT)
• Coolant Filter Inlet Pressure (5CPT)
• Coolant Filter Outlet Pressure (6CPT)
• Remote Pressure (10APT) – Only on compressors with the remote sensor
option
• Interstage Pressure (2APT) – Only on 2-stage compressors
• Aftercooler Discharge Pressure (7APT) – Only on compressors with
integrated dryer
Please note that if a sensor is currently reading a value that is +/- 10% of
its range from zero, the sensor will not be able to be calibrated. Please
make sure the sensor is being exposed to atmosphere before attempting
calibration.

Figure 38: Events Folder
The pages in the Events folder document up to the last 250 events that the
controller has experienced, and time stamps each. The events are recorded
in sequence, with number one being the newest and 250 being the oldest.
When a new event occurs, it becomes number one and all others are shifted
up in number.
The page numbers in the Title Bar are used to scroll through the events, with
each page displaying up to seven. Page one displays events one through six,
page two displays seven through twelve, and so on.
The following items will generate an event:

Active Warnings will be highlighted in amber while cleared Warnings will
have amber text.
Active Trips will be highlighted in red while cleared Trips will have red text.
Active Start Inhibits will be listed in the Event log, but not highlighted. The
display will indicate the compressor is not ready to start if a start inhibit is
active.
See the following lists for details about messages in each type of event.
Change Inlet Filter
Will occur if 1AVPT is greater than 0.7 psi vacuum (or 1. psi vacuum if the
high dust filter option is enabled) and the compressor has been loaded for at
least 8 seconds. This condition must exist for  seconds before the warning
is issued.
Change Coolant Filter
This will occur if the compressor has been running loaded for at least 8
seconds, is warmed up, and the coolant filter pressure drop (5CPT - 6CPT)
is greater than 25 psi. This condition must exist for  seconds before the
warning is issued.
Sensor Failure
This will occur whenever sensors 4ATT, 5DTT, 6DTT, and 7APT are recognized
as missing or broken. The sensor failure message shall follow the following
format: SENSOR FAILURE 4ATT. The 5DTT, 6DTT, and 7APT sensor failures will
be shown only when the integrated dryer is installed (accessed in the factory
settings menu). This condition must exist for  seconds before the warning
is issued.
Change Separator Element
Will occur if the compressor is loaded, the compressor is warmed up (the
injected coolant temperature is at least 120 °F), the package discharge
pressure is at least 90 psi, and the separator pressure drop is greater than 12
psi. This condition must exist for  seconds before the warning is issued.
High Airend Discharge Temperature
Will occur if the compressor is running and 2ATT is greater than 221 °F
(97% of 228) and the compressor is running. This condition must exist for 
seconds before the warning is issued.
High Sump Pressure
If the compressor is running loaded, has been loaded for at least 8 seconds
and the sump pressure is more than 25 psi above the rated pressure for the
compressor. If this warning occurs, the online and offline pressures will be
reduced. For example, a rated pressure of 100 psi would have a maximum
offline pressure of 110 psi. This warning would occur if the sump pressure
goes above 125 psi in this example. This condition must exist for  seconds
before the warning is issued.
Auxiliary 1
This will occur if auxiliary input 1 closes. The contact must be closed for at
least  seconds before the warning will occur.
Auxiliary 2
This will occur if auxiliary input 2 closes. The contact must be closed for at
least  seconds before the warning will occur.
