TRG 5-5...
Use four-core cable for wiring:
1. Connect terminal strip acc. to wiring diagram. Fig. 1, Fig. 2
2. You can connect additional equipment to the terminals marked in yellow and black
of the TRG 5-54, TRG 5-56 and TRG 5-58. Fig. 2
Commissioning
Use the following table indicating the resistance of the Pt 100 to ascertain the current
temperature of the fluid.
1. Connect the test wire direct to the terminal box.
2. Measure the resistance with an ohmmeter.
3. Find the corresponding value in the table below, read off the temperature and, if
necessary, determine the exact value by interpolation.
