4.7.1 Pulse generator connection

Danger!
For EK280 with internal power supply, the mains voltage must be switched off before
opening the housing, ensure it is not turned back on and verify that there is no voltage.

− Connect the LF pulse generator (LF reed contact) or the encoder of the gas meter for the calibrating
metering period to terminal "DE1" of the EK280.
− Connect the HF pulse generator (HF Namur) to terminal "DE2".

4.7.2 Parameterization

For programming Input 2 as the measuring input for HF acquisition, use the parameterization program
enSuite to send the following parameters to EK280 ( chapter 3.6, p. 21):
− EK280_xvx. - Application: Qm monitoring (Q2-HF) and storage in Archive 12 (*)
After loading of the file, it is also still necessary to set the pc value for input 2 (HF) and the limit, above which
any load excess is to be recorded. This limited is set at the factory to 20.0 m3/h. You can change this using
the EK280keyboard or enSuite (opening of the calibration lock is not required)
a) On the "Serv." display tab of the EK280 keypad:
Volume > Actual Volume > Parameter Settings > QbOW
Volume > Actual Volume > Parameter Settings > cp.I2
b) With enSuite under "Parameterize online" > "Parameter":
Volume > Actual Volume > Settings
