Commissioning
Make sure that the TRG 5- or TRG 5-4 and the associated control unit TRS 5-7 are wired in
accordance with the wiring diagram,
Fig. 15.
Check wiring
Apply mains voltage
Switch on mains voltage for temperature switch TRS 5-7.
Measure fluid temperature
Use the following table indicating the voltages of the thermocouples to ascertain the current
temperature of the fluid.
. Connect the test wires directly to the terminal box.
. Measure the voltage with a voltmeter.
3. Find the corresponding value in the table below, read off the temperature and, if necessary,
determine the exact value by interpolation.
