In this way, it is possible, for example, to connect and use further gas meters (or any other kind of meter)
with low frequency pulse output for recording. This means: If the "+" and "-" poles of the input x are of
sufficient duration (i.e., are electrically connected accordance with the preset pulse and period duration, the
input pulse is recognized and converted into a corresponding meter reading using the preset pc value (in the
specified units). This may also, for example, be the number of persons who cross a light barrier, or the
frequency with which a door is opened.

The use of the archived values for calibration purposes is only possible, if the input works as a
"repeating meter", so that it is possible to access the "calibrated values of the transmitting device,
where required!
The first step only produces a display of the meter reading determined at input 3 (abbreviation "V3"). In a
further application (
) an additional archive is set up which records the values accordingly.
The inputs are already programmed as pulse inputs at the factory so that a conversion is usually
superfluous. To program input 3 back to metering, send the following parameter file to the EK280 using the
parameterization program enSuite (

It is recommended to secure input 3 with a cover to prevent any misuse.
5.6.1 Archive for the additional metering input (Input 3)
For most applications, not only the current meter reading pursuant to
in an archive is specified. The example below therefore details the hourly recording in accordance with the
measuring period of the EK280 in a flexible archive.
For reliable activation of input 3 as a metering input and for recording in the flexible archive, you transmit the
following parameter file to EK280 by means of the parameterizing program enSuite in the sub folder

EK280_2V2x - Application: Input 3 =Counting input (m3) and hourly storage in flexible archive 13 (*)
The input is set with the wpp file to the factory default setting. Hence it is then necessary to check and adjust
the input parameters in accordance with
The counter value appears both via input 3 and also in the Main Menu. The Main Menu is also set up with a
display in the form of a "List" pursuant to
. Accordingly, the counter value "V3" appears
directly in the Main Menu.
In principle, the make-up of the archive is flexible. In this example, the following values are recorded hourly
according to the wpp file.
