Heating Circuit
The cycle temperature is fixed by the μP depending on the selected program.
The temperature control is guaranteed by the μP through the NTC temperature sensor. The temperature
sensor reduces its resistance according to the temperature increase.
The reduction in the ohmio value of the temperature sensor is detected by the μP; as soon as the
selected temperature is reached the power supply to the heating element will be paused.
The NTC sensor is integrated in the heating element.
Variations of NTC resistance
Temperature (°C) Resistance (Ohm)
25 4815 +- 207
40 2563 +- 102,5
60 1196 +- 26,31
80 602 +- 19,89
NTC-Sensor
1. NTC resistance
2. Metallic casing
3. Connections
4. Plastic casing
To check the NTC sensor function you can measure the ohmic resistance between the contacts
J9/8 and J9/9.
Security
- The μP will be break off if an anomaly on the termistance circuit is detected :
cut or short-circuit. (see Page Service-Program fault display E70)
- The heating phase is not executed.
