Programming the Outputs
(
OUTPUT
)
Depending on the purchased model, the meter may
be available with two open collector outputs, two solid
state relays, and one 4-20 mA output. The Output
menu will only show options for the available outputs.
See Ordering Information on page 3 for details.
Open Collector Outputs (
OPEN COLLECTR
)
The meter is equipped with two NPN open collector
outputs that may be set up for pulse outputs, alarms,
timed pulses, total reset, or disabled.
Pulse outputs can be set to transmit the rate, total, or
grand total. Output 2 may be used to generate a
quadrature output based on the other open collector
output. An output test mode is also selectable to gen-
erate pulses at a constant programmable frequency.
Alarms are available based on the rate value or the
digital input. The alarm status will show on the display
even if the output is not wired.
A timer output (
TIMER
) turns the open collector on
and off at the specified time intervals. The timer can
be set as single-shot or continuous timer.
A total reset output generates a pulse whenever the
total is reset, regardless of the reset method used.
The On time is programmable between 0 and 9,999
seconds.
The stopwatch output (
STPWATCH
) allows the open
collector to be manually activated by starting the stop-
watch. The stopwatch count can be displayed on the
top or bottom line.
The output may be disabled by selecting
DISABLE
.
The Open Collector Outputs are programmed in the
following manner:
Pulse Output (
PULSE
)
Pulse outputs may be assigned to output the rate, to-
tal, or grand total at a programmable factor. If the out-
put is assigned to rate, the factor is a multiplier that
determines the number of pulses generated based on
the rate. For example, if the meter display shows 100
gallons/second and the factor is set to 2, the number
of pulses generated per second would be 200. If the
output is assigned to total or grand total, the k-factor
corresponds to the number of pulses generated per
unit of measure. For example, if the k-factor is 0.001
and the units are gallons, one pulse will be generated
for every 1,000 gallons. The maximum frequency is
1,000 Hz.
Setting output 2 to quadrature will duplicate the other
open collector output, but lag by 90 degrees out of
phase. The other output should be programmed as
desired for the quadrature output function and must
be a pulse (
PULSE
) output selection. The quadrature
maximum frequency for both outputs is 500 Hz.
The
TEST
option will output a fixed number of pulses
per second based on the
FREQ
value entered.
