15.1 Operating options
The SITRANS FC can be operated in different ways:
▪ IR (Infra-Red) switches on the display
▪ Digital communication (e.g. HART or Modbus)
The section below describes how to operate the system using the IR switches on the
display.
The display is a device option and therefore not always available.
For more information on how to operate the transmitter and its functions, and on digital
communication, see applicable Function Manual.
Be aware that all covers are closed before operating in order to prevent disturbance of

other sensitive electrical equipment due to increased electromagnetic emissions.

values that are entered via the display are limited to 6 digits.

The controls on the display are IR switches. They respond as soon as an object, such as
a finger, is in close proximity. It is not necessary to apply pressure to the display surface.
