APPENDIX
Putting the power module into operation
After reconnecting the TME 400 supply voltages, the current loop power supply
must be connected to X9 and the current output parameterized.
Caution
114
The voltages of the current loop and the external supply must be electrically
isolated (galvanically isolated see chapter 2.1 Electrical connections, espe-
cially the connection drawings in the Ex- /Non-Ex area at the end of the chap-
ter).
Parameterization of the current module
To complete the installation, various parameters must be checked or configured.
To do this, the parameter protection must be removed, either by entering the code
word (see chapter 4.3.3.7 Settings) or by pressing the calibration button (see Fig-
ure 19: Electronic with power module).
1. First the date and time must be entered in the coordinates X1 and X2
2. The current output parameters F02, F03, F04, F05 (see chapter 4.3.3.3
Current output) must then be parameterized according to the application.
For example, a typical parameterization may look like this:
F02:
F03:
F04:
F05:
For testing, F03 can be set to 0 (default) and a current value in the range of
4 - 20mA can be selected with F06.
