43024 Debris Removal DEB: Unable to calibrate <Sensor Name> pressure sensor Japanese_Newspaper_OEM_Engine Lotem_Quantum Magnus_400 Magnus_800 Magnus_VLF Thermoflex Trendsetter_400/800 Trendsetter_NEWS Trendsetter_Series_4 There was a problem trying to calibrate one of the pressure sensors in the debris removal system. A device error has occurred: You may be able to continue by pressing the "resume" button onscreen (if present) or by resetting the device and workstation. For support under your service contract, contact the Creo Response Center at 1-(800) 472-2727 or online at http:\\eCentral.creo.com (or your local service representative) To speed troubleshooting, please make a note of error numbers, the media type/size and any information about the workflow or job that might be relevant. This error is reported. Cause 1: The zero pressure value for the sensor is not close enough to zero. The line may be plugged and under vacuum or the sensor maybe defective. Solution: Disconnect the sensing line at the sensor and reset the output device. If the error goes away then there is a blockage in the line that keeps the sensor under vacuum. This is most likely to happen to the nozzle sensor, since the collection nozzle could become clogged with debris over time, blocking the small pressure-sensing hole. Clean the nozzle (see UDRC Techplanet site for detailed instructions): HYPERLINK "http://techplanet.creo.com/output/heads/debris_removal/nav/proced.htm" http://techplanet.creo.com/output/heads/debris_removal/nav/proced.htm If you are using a TH1.x nozzle that has its sensing port on the top of the nozzle, replace the nozzle with the current (min Ver C) to avoid future problems. If the error does not go away then the sensor must be replaced. Note: 'Bellmouth' sensor is the 0-100" scale Setra brand sensor, and 'Differential' sensor is the 0-10" scale. Cause 2: On systems equipped with a Setra nozzle sensor. The control lines to the nozzle sensor may have been touched together while energized. This will damage a diode on the Lionel board causing the sensor to display half its value. This value will be greater than +-5% from the anticipated 0 value and not permit calibration. Solution: Start the system then use the command "debris debug" to list the offset values (this command may not be available in Lotem Control Software). The offset for the nozzle Setra sensor should be about 180. If the value is about 90 this is your problem. Unplug the UDRC and remove the chemical upgrade enclosure. Measure the resistance between the negative lead of the pressure sensor and the ground socket on the Lionel board. The value should be 220 OHMS. If not, replace the Lionel board or remove the following diodes from the board: D37, D46, D41.
