9.0 OPERATING INSTRUCTIONS
9.12 WARNINGS
When a WARNING occurs, a large question mark will flash on the display screen.
If multiple WARNINGS exist, the small up/down arrows will appear in the upper right corner of the display screen. The multiple WARNINGS can be seen by pressing the up and down arrow buttons. Pressing the STATUS button will display the CURRENT STATUS screen with the WARNING button indicating that a WARNING still exists.
A WARNING will not cause the unit to shut down. The unit will continue to run in its normal operation and the WARNING will remain displayed until reset.
A Warning needs to be reset by the operator by pressing the RESET button twice.
The possible Warning messages are as follows;
HIGH AIREND DISCHARGE TEMP − This will occur if the Airend Discharge exceeds 97% of the alarm limit, 109° C (228° F) and is not adjustable.
CHANGE COOLANT FILTER − This warning will occur if the high side pressure is 1.4 bar (20 psig) greater than the low side pressure.
CHANGE INLET FILTER − This will occur if the Inlet Vacuum is greater than 0.05 bar (0.7 psig).
CHANGE SEPR ELEMENT − This will occur if the pressure differential across the separator is 1.0 bar (12 psig).
SENSOR FAILURE − This will occur if a sensor is recognized as missing or broken.
HIGH DISCHARGE PRESS − Will occur if the unit is under the control of an external device, such as an ISC, and the discharge pressure is greater than the immediate stop pressure.
AUXILIARY WARNING 1 or 2 − Will occur if the auxiliary warning input closes.
REMOTE PRESSURE SENSOR FAILURE (option) − This will occur if the remote pressure sensor fails. If this happens, the lntellisys will start using the package discharge pressure sensor to measure system pressure.
CONDENSATE DRAIN ERROR − On 2 stage units, this will occur if the condensate drain error contacts close while the unit is running.
9.13 SERVICE WARNINGS
SERVICE − Service warnings occur when the unit has operated a certain number of hours, based on the total hours, or has operated for a certain number of months, based on the real time clock. Service warnings can have multiple levels, depending on the service level selection.
This will be set prior to the compressor being shipped from the factory. When a service warning occurs, contact your local IR service representative.
9.14 INITIAL CHECK ALARMS:
The following alarms will only occur when the machine is not running. These alarms are related to high temperature, power loss, and sensor calibration. They will have the same display mode as other alarms.
HIGH AIREND DISCH TEMP− Will occur if airend discharge temperature is greater than 95% of 109° C (228° F).
CHECK SETPOINTS − Will occur if the controller has determined that some of the data stored in memory contains unacceptable values.
INVALID CALIBRATION − Will occur if the sensor zero value is −10% to +1% of its scale. See Sensor Calibration.
