4.4.1 Electrical connection temperature switch TSA (accessory)
The temperature switch TSA is installed in a cooling circuit with an oil/air cooler ELK as a typical application. Through reaching
the switching temperature the fan-motor is switched-on and the oil will be cooled. After falling under the hysteresis the motor
shuts off.
If the cooling matrix has an optional temperature contact type TSA, the maximum values (see below) must not be exceeded. If
connecting it to a relay, a free wheel circuit has to be added. Carry out the connection according to the following specifications
