Send parameter file
Prerequisite: A communication link between enSuite and the EK280 via optical interface, modem or network
(TCP/IP) has been set up (see chapters 3.1 to 3.3).

Select " Navigation " on the left-hand side.

Click on the plus sign next to " Connections " in the newly-opened navigation window.

Click on the entry beginning with the serial number of the connected device.

The device identifier is now displayed at the bottom of the navigation window. If no command list is
displayed underneath, click on the arrow next to the device identifier.

Select " Send parameter file "

Click " Open... " in the top right

In the dialog box "Select WPP file" select the corresponding directory and the parameter file and
then press " OK ".
i
In enSuite from version 2.7 onwards, the name and issue (in brackets) of the parameter file are
both displayed. The file extension ".wpp" is not displayed.
i
If needed, any arbitrary wpp file can be selected with the " File system
…
" button. Make sure
that this manually selected wpp file is suitable for the EK280 software version.

Click on " Start " in the bottom right and wait until the file has been successfully sent.
i
In the center of the window, you will see the number of rows that have been sent along with
the number of rows containing errors (if applicable)
You must check in such cases whether the necessary locks are open and/or whether the file
used is suitable for the device version. Contact the Elster hotline (see EK280 handbook) is
necessary.

To begin another task, click again on " Navigation " on the left-hand side.

Volume measurement
Input 1 (terminal "DE1") is used as counter input for the volume conversion device, for applications with
automatic conversion input 2 (terminal "DE2") is also used.
Counter inputs for detection of gas volumes for conversion are generally under calibration lock, i.e. the
connector terminals are sealed and parameters affecting the counter can only be updated with the calibration
lock open.
The following pulse generators or encoders may be connected to input 1:
Volume encoder Specifications
LF pulse generator Reed contact or open collector transistor
HF pulse generator NAMUR max. 2500 Hz, for use only with external power supply (not battery)
NAMUR encoder a NAMUR protocol encoder a
NAMUR encoder a-b NAMUR protocol encoder a and b
SCR EDIS encoder SCR EDIS encoder with EDIS95 protocol
SCR OBIS encoder SCR encoder with OBIS05 protocol
