Commissioning and operation using communication
•
Wire up the Barcon (see chapter 2.5 "Electrical connection").
•
Decide which tool is to operate the Barcon and wire it up accordingly.
(see chapter 3.4 "Operation using PACTware®" and see chapter 3.5
"Operating with the HART protocol via universal HART communicator")
•
All used parameters are listed in the matrix of parameters (see chapter 8
"Matrix of parameters").
By entering a code, the entries in the Parameter are reset partially or completely to
factory settings. Further information on the various types of reset and their effects are
given in chapter 5.3 "Reset".

The damping affects the speed with which the output signal and the digital display
react to changes in pressure.
For setting the damping using the handheld terminal, the damping switch must be set to
"on". Values for damping between 0 s and 40 s can be selected using the handheld
terminal.

Selecting the pressure units determines in which units the pressure-specific parameters
are to be shown. The pressure units available are given in the table below.
After selecting new pressure units all information on the pressure are converted into the
new units, e. g. 0 bar ...1 bar = 0 psi ... 14.5 psi.
