EK280

4.6.2 Parameterization

To program input 2 for the pulse comparison with input 1, send the following parameter file to the EK280
using the parameterization program enSuite ( chapter
− EK280 - Input 2 = Pulse Comparison with input 1 (*)
The deviation amount between the two pulse generators, above which a warning is triggered, is editable.
The default is 4 ("maximum number of disturbance pulses") within a 4000 pulse ("pulse window per
disturbance pulses").
This setting can be updated using the EK280 keypad or with enSuite:
a) On the "Serv." display tab of the EK280 keypad:
Data book > Inputs
Data book > Inputs
a) With enSuite under
Data book > Inputs
Data book > Inputs
− The maximum number of error pulses is
− The pulse window is

4.7 Monitoring the load at measurement conditions Qm in the archive

The EK280 offers the possibility of monitoring the loads of connected counters. In this way it can be
ascertained whether pressure should be increased slowly or a valve/flap be opened suddenly during
commissioning of the plant. In this case there is a risk that the connected counter (this is particularly critical
with a turbine) will be subjected to a pressure shock and may be damaged (bearing damage).
Monitoring will not be constant, but is started only when a threshold value is exceeded. When this is
exceeded, recording will commence at the most rapid interval of 2 seconds. The last 5000 rows of the
measured load of input 2 (Q2) will be archived in flexible archive 12. The maximum record size is 5000 rows.
i
The HF probe of the gas meter (A1S / A1R) must be connected to input 2!
The EK280 must be mains supplied in order to be able to record the pulses from the HF probe!
