3n. Sensor for the controller
PT 100
A faulty sensor will typically prevent the compressor from starting.
If the sensor is covered with ice, the compressor will run more than usual and cool too much.
The easiest way to check the function of the sensor, is to place your hand around the sensor. If the
temperature recorded on the display in the front panel does not rise, the sensor is faulty and needs to
be replaced.
The sensor can also be tested with an ohmmeter.
The PT 100 sensor is located in the stage on the right side of the freezer.
Remove the alu. panel.
Remove the sealing material around the introdcuction and pull out the sensor.
Remove the sensor pins on the terminal 11 and 12 of the controller. See wiring diagram page
25.
Remember! The sensor must be replaced with a sensor with the same characteristics as the original.
