To get this fault, one or more of the Paddle Temperature Sensors is reporting erroneous low data of < 5oC. The fault message on the Touch Screen Display will indicate which station is having the problem and the heater to this station will be disabled. If known, notate the temperature of the paddle (or the adjacent ones) when this fault occurred. The remaining stations will continue to run as normal. Depending on the time at which this fault occurred, one may want to disregard the test results from the suspect station.
When the run in progress is done, turn the instrument off and back on again. Using the Diagnostics mode, select Temperatures and see if the station that reported the problem reading is still doing so. If the problem reading is ongoing an E1 fault will be generated again. If not, run a brief test. Again using the Diagnostics mode, select Heater Test, press Paddle Heater Power Enable. Having done so, turn on all six paddle heaters. Monitor the temperatures closely to see if the E1 fault returns during heating of the paddles. Do not leave the instrument at this time as the heaters will stay on potentially overheating them if not controlled. Turn the heaters off when they reach 95oC. Allow the paddles to cool back to ambient temperature. If during the heating or cooling, the fault recurs, the Paddle Bar will need to be replaced. If the fault does not happen again, leave power on to the instrument overnight while in the Select a Function screen. The program is always monitoring temperatures when power is on and if the fault occurs again during this time, the Paddle Bar will need to be replaced. If the fault does not recur during any of these tests, it is possible that a voltage fluctuation or static discharge near the sensor may have caused this fault. The instrument may be put back into use. Keep record of any further E1 faults and if any do occur again, replace the Paddle Bar.
Refer to Service Procedure #021 for replacement of the Paddle Bar Assembly (TDF23). This will require calibration of the temperature sensors and proper setting of the mixing stroke.
