5.3.1.8 Setting the alarm limits for gas pressure and temperature measurement
Ex works, the alarm thresholds are set to sensible values. If a change is necessary, proceed
as follows:
 Move the cursor to the "Serv" tab and via the following paths to the alarm thresholds:
Serv.  Measured values  Pressure  pMin and pMax
9
Serv.  Measured values  Temperature  TMin and TMax
 Press the key combination ENTER  +  to enable the entry.
 Move the cursor with the arrow buttons

5.3.1.9 Setting replacement values for gas pressure and temperature
If the gas pressure or the gas temperature cannot be measured due to a fault or if pressure
and temperature are outside the alarm limits defined in chapter 5.3.1.8, an adjustable
replacement value (fixed value) is used to calculate the standard volume. The volume
thereby calculated is counted in the separate fault volume meter VbD (Base Volume
Disturbed).
The total base volume counter VbT is keep on counting although there is a disturbance. The
total base volume calculated under these faulty conditions has no measuring relevance. It
must not be used for billing purposes.
The replacement values can be found at the following paths:

The values are changed as a rule in the same way as described in chapter 5.3.1.8.
5.3.1.10 Parameterization of the outputs
The setting of the cp values (pulse constants) for the outputs can be carried out
via the enSuite software as an alternative.
The following functions are preset for the outputs as factory settings:

These values are not required in the performance as Temperature Conversion device.
10
These values are not required in the performance as Temperature Conversion device.
