The high position of the lower plate is detected by the sensor [1] when it intercepts the bar [2]
integral with the lower plate.
The low position of the lower plate is detected by the micro-switch [3] which stops the electrical
motor when it is pressed by the bar [4] integral with the lower plate.
Measurement of the plates temperature
The measurement of the plates temperature is done by two thermocouples [1], one for each
plate. The thermostats [2], depending on the difference between measured temperature and set
temperature, turn on or off the resistors set on the plates.
