Troubleshooting
NTC LOW TEMP
The programme unit indicates an interruption
with the temperature sensor or the tempera-
ture is below -5 °C.
Try to restart the machine (i.e. reset the error
code) by pressing START.
1. Undo the temperature sensor connections and
measure the resistance of the sensor. The resistance
should be as in the table below:
Approximate values for a fully functional
temperature sensor
T (°C) R (ohm)
19 6109
20 5844
21 5592
22 5353
23 5124
Resistance OK Incorrect resistance
The temperature sensor is probably
defective.
2. Exit the programme using a. Enter the service
programme and read the temperature (the display
window shows 0°C). Short-circuit inputs 1 and 2 on
card switch X1. Verify that the display window shows
100°C.
Yes No
Incorrect temperature sensing on the
programme unit card. Replace the card.
Incorrect cabling to the . Verify and replace if
necessary.
