Description
Value
Alarm
Assignment of available channels.
> Select Alarm from drop down list to define alarm signal via relay for selected parameters.
Measurement value
> Select desired parameter for alarm signal from drop-down list.
Limit
> Enter minimum value (lower limit) for alarm activation.
Type Specify alarm activation above or below set limit.
above
Tick to trigger alarm above limit.
below
Tick to trigger alarm below limit.
Hysteresis > Enter hysteresis value to define upper and lower limit which has to be exceeded to trigger an
alarm (limit ± hysteresis).
A suitable hysteresis value prevents the alarm from being triggered unnecessarily by small
measurement deviations.
Delay > Enter minimum time span for measuring values exceeding the upper or lower limit. Only after
this time an alarm is activated.
This option avoids that an alarm is activated due to short term deviations.
Test Channel 1
Tick checkbox to activate signal test.
Test value 1 Specify low or high signal-
low / high

Value
Pulse
PulseAbs
PulsePos
PulseNeg
Settings for pulse output signals for volume counter (totalizer).
4 types of counters (totalizer) can be parameterized taking into account the flow direction
(positive +V in flow direction / negative -V against flow direction).
See also under Settings Totalizer (7.9.4)
Pulse:
Volume value - difference
(+/- sign are taken into account in summation of V)
V = +V (volume positive) -V (volume negative)
PulseAbs:
Absolute volume
(- sign of negative volume is not taken into
account in summation)
V abs (absolute volume) =
V (volume positive) + V (amount volume negative)
PulsePos:
Total positive volume (+V)
(V against flow direction)
PulseNeg:
Total negative volume (-V)
(V in flow direction or “reverse flow”)
> Select pulse types from drop down list to define pulse output and export total volume values.
