EK280
7.5.1.2 EK280 jumpers
X6: No jumper
or one jumper on the pins located
near the terminals
Connectible RS232 interface devices often have a direct or capacitive ground potential connection. There is
therefore a risk of interference coupling via ground loops, which may affect pressure and temperature
measurements.
The position of the two jumpers on X5 by the terminals means that the EK280 interface is electrically isolated
from the rest of the circuit and therefore electromagnetic interference coupling is prevented.
The current required by the EK280 interface of around 1 to 2 mA is therefore supplied by the signal
connected to the "Ri" terminal.
7.5.1.3 Parametrization of the EK280
i
For parameterization of the EK280 you need a connection cable for the optical interface as well
as the enSuite program. enSuite can be downloaded free of charge from the Honeywell website
in the "Software Downloads" section:
www.elster-instromet.com/en/software-downloads
j) a) Closing the time windows
In order that the parameterization works correctly the time windows 5 and 6 must be closed. To do this:
− Connect a PC or laptop with enSuite installed to the EK280 optical interface using the connection
cable.
− Start enSuite and set up the communication link to the EK280.

− In call windows 5 and 6 set start and end to the same value for each one and then select the
"Transfer changes to device" icon at the top of the enSuite window.
− Then wait a minute, for any communications activity in progress on the EK280 to be safely stopped.
