Troubleshooting
NTC HIGH TEMP
The programme unit indicates a short-circuit
with the temperature sensor or the tempera-
ture exceeds 98°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. Reset the connection on the sensor and exit the
programme using a. Enter the service programme
and read the temperature. Disconnect one of the
inputs 1 and 2 on card switch X1. Verify that the display
window shows 0°C.
Yes No
Incorrect temperature sensing on the
programme unit card.
Incorrect cabling to the temperature sensor. Verify
and replace if necessary.
