3.05.07 OUTPUT Unit of pulse output:
1) PULSE RATE (frequency): pulses per unit time, setting by entering
a frequency at 100% volume flow rate.
2) PULSE/UNIT (totalizer pulse output): pulses per unit volume ,
setting by entering a value for the number of pulses for each volume
or energy unit. Each pulse has a fixed volume (i.e. 1 pulse per
0.1 liter). This is the best method of remote totalizing, as pulses
simply need to be counted.
3.05.08 PULSE RATE Pulse rate (frequency) value for 100% scale. If function 3.05.07 is set
to PULSE RATE, the following units can be chosen using this function:
pulse/s, pulse/hr, pulse/min.
Range: 10 pulses/h...2000 pulses/s, default setting: 1000 Hz.
3.05.09 PULSE/UNIT Pulse value per volume unit for totalisation. Note: Check that the
maximum flow span will not cause the number of pulses generated
per second to exceed the maximum of 2000 Hz!
If function 3.05.07 is set to PULSE/UNIT, the unit and number of
pulses per unit can be set for the flow measurement using this
function. Available options: pulse/m
3
, pulse/l , pulse/US-Gallon,
pulse/bbl, free user definable unit.
Default setting: 1, maximum number of pulses per unit: 7870000.
3.05.10 PULSE/UNIT Pulse value per heat energy unit for totalisation. If function 3.05.07 is
set to PULSE/UNIT, the unit and number of pulses per unit can be set
for the heat power measurement using this function. Available
options: pulse/MJ, pulse/GCal, pulse/MCal, pulse/GJ.
Default setting: 1, maximum number of pulses per unit: 1000000.
3.05.11 PULS WIDTH For frequencies ≤10 Hz the following pulse widths can be applied:
1) 25 ms for P
100%
< 10 Hz.
2) 50 ms for P
100%
< 10 Hz.
3) 100 ms for P
100%
< 5 Hz.
4) 200 ms for P
100%
< 2.5 Hz.
5) 500 ms for P
100%
< 1 Hz.
For frequencies 10...1000 Hz: 50% duty cycle, 1000...2000 Hz: 70/30%
duty cycle (Note: pulse width may vary 5 ms, pulse period may vary
25 ms!)
3.06.00, DIG INPUT (Digital input)
3.06.01 FUNCTION Function of digital input. The digital input terminal is the same as the
current output terminal. Therefore, when a digital input function is
selected, the function of the current output needs to be set to OFF
and the current output range has to be set to 0...20 mA. The following
options are available for the digital input:
1) OFF: switched off, no function.
2) RST TOTAL: reset display totalizer(s), independent of the
programming of function 3.07.08.
3) RST ERROR: reset error messages.
4) FORCE ZERO: force display and outputs to their "zero" values.
5) BATCH: start (input high) or stop (input low) a batch, only available
for the batch-version.
