Pulses/Unit
The Pulses/Unit parameter lets you set how many
pulses per unit of measure will be transmitted. The
configurable range is from 0.0001 to 99.999 pulses/
volume unit, however the max. output frequency of
10,000 pulses/sec. (10 kHZ) must not be exceeded.
Pulse Width
This parameter establishes the “On” duration of the
transmitted pulse. The configurable range ist from 0
msec to 9999 msec. If 0 msec is configured, pulse width
is automatically adapted depending on pulse frequency
(pulse/pause ratio 1:1).
During the configuration the program checks if
pulses/unit and pulse width are in accordance with full
scale defined, if not an error alarm is displayed. In case
of an error alarm, scale, pulse width or full scale need
to be adapted.
Preset
Amount Preset amount lets you set the reset value for the
associated PS totalizer when the digital input is set to
Batch Reset. You can configure preset amounts from
0.01 to 99999.99 totalizer units in steps of 0.01 volume
units.
Preset amount is counted down from the configured
value to 0 and a digital output shows that the preset
amount has been reached.
Note: You can only set one preset amount. If you set
the preset amount for digital output 1, it will be the same
for 2, 3 and 4.
Flow Set
Point The Flow Set Point (min, max) establishes as a
percentage of full scale flow, the threshold at which the
output alarm will be activated. You can freely select
thresholds in 1% steps. Flow rates below/above the
threshold will activate the output alarm.
Output Type
The Output Type parameter lets you set the output
switch to “normally closed“ or “normally open“.
Hardware
selection
The hardware type parameter lets you select the type
of hardware used to drive the two digital outputs 3 and
4: Either passively as open collector or relay (solid state
relais SSR).
Full Scale
Frequency This parameter allows to define the digital output 1, 2 or
3 as frequency output. Full scale frequency can be
configured from 0 to 10,000 Hz.
Output hardware should be defined as open collector –
otherwise problems may occur with higher frequencies
(> 500 Hz).
