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 generate 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 stopwatch. The
stopwatch count can be displayed on the top or bottom display.
The output may be disabled by selecting
DISABLE
.
The Open Collector Outputs are programmed in the following manner:
