Comment / Corrective Action
Controller processor detected a calibration data checksum error.
1. Attempt to recalibrate the system.
2. If calibration fails, replace the controller PCB.
3. Retrieve the DRPT and contact technical support.
Controller processor detected that the flow sensor drift check has failed. (Flow
sensor drift and calibration information can be monitored using the RASP utility:
select option D) Drift Screen from the RASP utility menu).
1. Attempt to recalibrate the system.
2. If calibration fails, replace the controller PCB.
3. Retrieve the DRPT and contact technical support.
Controller processor detected that the calibration table version check has failed.
1. Attempt to recalibrate the system.
2. If calibration fails, replace the controller PCB.
3. Retrieve the DRPT and contact technical support.
Controller processor detected that the flow sensor drift check has failed. Flow
sensor drift and calibration information can be monitored using the D) Drift
Screen from the debug screen using the RASP utility, capture screen output to a
file.
1. Attempt to recalibrate the system.
2. If calibration fails, replace the controller PCB.
3. Retrieve the DRPT and contact technical support.
Controller processor detected that the drift check on the primary pressure has
failed. Pressure sensor drift and calibration information can be monitored using
using the "D) Drift Screen" from the debug screen using the RASP utility, capture
screen output to a file.
1. Attempt to recalibrate the system.
2. If calibration fails, replace the controller PCB.
3. Retrieve the DRPT and contact technical support.
Controller processor detected that the calibration table is blank.
1. Attempt to recalibrate the system.
2. If calibration fails, replace the controller PCB.
3. Retrieve the DRPT and contact technical support.
Controller processor detected that the drift check on the secondary pressure has
failed.
1. Attempt to recalibrate the system.
2. If calibration fails, replace the controller PCB.
3. Retrieve the DRPT and contact technical support.
Controller processor detected an error in format of the calibration data in
EEPROM.
1. Attempt to recalibrate the system.
2. If calibration fails, replace the controller PCB.
3. Retrieve the DRPT and contact technical support.
