4.6.2 Temperature sensor
The temperature sensor is connected using a 2 or 4-cable system.
4-cable system
The temperature sensor's connection wires are duplicated in the direct vicinity of the sensor. Thus a
total of 6 wires are required (2 wires for the irradiation sensor and 4 wires for the temperature sensor).
The connection is established without using bridges on the terminal strip in accordance with the
following connection plan:
2-cable system
If measuring is carried out using a 2-cable system, the connection is established in accordance with
the following connection plan:
