 'Temp Out of Range" Error 5500 sc Silica/Phosphate Analyzer
Antwort
The "Temp Out of Range" error on a 5500 sc Silica or Phosphate analyzer is caused by a failure of the colorimeter heater or the sample heater. The colorimeter heater is controlled to maintain 50 °C, and the sample heater is controlled to maintain 50 °C (±7 degrees C). To determine which device is causing the error, press the Menu key, and go to View Data > Analyzer Data. Check the CELL TEMP and SAMPLE TEMP values to see which one is not at the proper operating temperature. 

Check the wire connections, or determine if a thermal fuse has opened. The sample heater on original version instruments had a non-resettable fuse, which would require the replacement of the entire sample heater assembly. The newer version instruments have a resettable fuse. Is it possible to reset the sample heater fuse on the 5500 sc Phosphate and Silica analyzers?  The colorimeter heater has a non-resettable fuse, which would require replacement of the colorimeter assembly, or the colorimeter circuit board assembly.
