If the blue represents the input being active you can see the different trigger
points below.

Always high
The output driver setting offers the possibility to invert the action from the
alarm switch and set the alarm to a predefined state which is convenient for
testing systems.
The “Always low” and “Always high” override all alarm settings and flow signals.
Please make sure that you take precautions before
you use these options in a “life” system.
4.11.3. Totalizer
The totalizer calculates how much gas has totally passed through the flow meter
based on the measured flow and the factor time. The instrument has 2 totalizers. Each
can display a maximum of 8 digits. The totalizer value will be stored internally as an
IEEE 754 floating point number. The internal totalizer will never roll-over, the maximum
value far exceeds the lifetime of the instrument. One of the two totalizers is resettable,
the other can never be reset and always continues to count for the lifetime of the
instrument. Both the totalizer values are stored every 10 minutes in a permanent
memory so even if there is no power supply the last stored value will still be kept. If
you apply power again the saved value will be restored (Unless you activated the
“reset on start” feature).
Please note that if the flow rate exceeds the full scale of the unit (overflow), the
totalized value will not be correct. Even if there is an overflow the totalizer operation
will continue normally. However since the flow value is limited the totalizer is totalizing
the limited flow value only.
If the totalizer value exceeds the possible 8 digit display, you can set the totalizer
engineering units to a suitable unit that can display the value within the 8 digits, for
instance m3n or kg. See section 4.12.3 Units .
Read
Read the totalizers (for instance in-case you only activated the flow screen).
N: is the non-resettable totalizer, R: is the current value of the resettable totalizer.
Reset
Reset the resettable totalizer to zero
Configure
Reset on start
Activate this option if you want that the resettable totalizer is set to zero
every time you switch the unit on. Please note: Upon start-up the
totalizer will be silently reset without asking for confirmation. It simply
resets the resettable totalizer to zero every time you switch the unit on.
Remark: With the alarm module it is possible to reset the totalizer
with an external remote switch or signal.
