Pulse Width
S
This parameter establishes the “On” duration of the transmitted pulse . The
configurable range is 0…2000 ms . If 0 ms 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 .
Pulse/Unit
S
The Pulses/Unit parameter lets you set how many pulses per unit of measure
will be transmitted . The maximum output frequency of 10,000 pulses/sec .
(10 kHZ) must not be exceeded .
For example, assuming the unit of measure is gallons:
• Setting the Pulses/Unit to 1 will transmit 1 pulse every gallon
• Setting the Pulses/Unit to 0 .01 will transmit 1 pulse every 100 gallons
You must configure pulses/unit if the function of the selected output is to be
forward, reverse or AMR pulse .
Frequency
S
This parameter establishes to define the digital output as frequency output . The
full scale frequency configurable range is 0 .01…10,000 Hz .
Set Min./Max.
S
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 .
Preset Amount
S
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 amount in the
adjusted volume unit .
Preset amount is counted down from the configured value to 0 and a digital
output shows that the preset amount has been reached .
Out 1 Function
Out 2 Function
S
(continued on next
page)
From the sub-menus Out 1 Function and Out 2 Function, you can configure
functional operation of the 2 digital outputs . For example, you can select
“forward pulse” for the digital output and define the pulses-per-totalizer unit via
“pulse scale” .
The two outputs can be operated as open collector passively or actively .
Passive output:
Active output (if analog output is not used):
