3.3 Connection – Notes
Mainly, the electrical characteristics are defined by the variable connection technique.
The connection can be made only in connection with the device specific pin
assignment!
At the delivery of the measuring system one device specific pin assignment in printed
form is enclosed and it can be downloaded afterwards from the page
„www.tr-electronic.com/service/downloads/pin-assignments.html”. The number of the
pin assignment is noted on the nameplate of the measuring system.
For multiple redundant measuring systems, the connection must be carried out
separately for each interface unit.
3.4 Status LEDs at multiple redundant measuring systems
Multiple redundant measuring systems have a separate status LED for each interface
unit.
