8 - OVEN TEMPERATURE SENSOR (PT500)
To control oven temperature, the OVC3000 system uses a temperature sensor mounted on a bracket which
is screwed onto the oven muffle.
A PT500 resistance-type platinum sensor provides the control board with the information that is required for
the following functions:
- Cycling the heating elements until they reach the desired temperature
- Shutting down heating elements in case of overheating or sensor malfunction
- Delaying cooling fan start-up and shutdown
- Recognizing relay malfunctions
The temperature sensor is hermetically sealed in a metal sheath, which must be connected to earth.
