4.5.2 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.
Pulse generator
NF/HF or
encoder
− Connect the first pulse generator (e.g. LF/reed contact) of the gas counter to terminal "DE 1" of the
EK280.
− Connect the second pulse generator (HF/NAMUR sensor) to terminal "DE2".

4.5.3 Parameterization

In order parameterize this function, you can use the parameterization program enSuite to connect to the
EK280.
Using enSuite select "Parameterize online" >

4.6 Pulse comparison

Pulse generator errors can be detected early using pulse comparison.
In principle, any two pulses may be compared. The process for securing the custody transfer measurement
using a pulse generator on input 2 to monitor the pulse generator on input 1, is described here.
