The open collector outputs trig ger when the total or
rate (assignable; see pro gram ming step 2) equals the
corresponding Preset (A or B). When the output is as-
signed to "
pul
" (pulse output) the outputs trigger with
each count of the total (or multiples).
When the outputs are as signed to the "total", the op er a tor
can assign a duration of time (.01 to 599.99 sec.) that
the output will remain energized. If 0.00 is as signed,
the output will latch until reset. If output A is set at a
duration (other than 0.00), the totalizer will au tore cycle
when Preset A is reached. At this time, output B will
de-en er gize (if it was en er gized). Preset A is the fi nal
preset and should be set higher than Preset B, when
both outputs are as signed to the total. If output A is
set at a duration other than 0.00 and Preset A is set
less than Preset B, Preset B will be ignored (provided
that they are both as signed to total). The totalizer will
never au tore cycle at Preset B.
When the outputs are assigned to the "rate", the out-
puts can be assigned a hysteresis (alarm range). The
hysteresis is the number of units below the preset that
the output will remain energized. EXAMPLE: Preset set
@ 100; Hysteresis set @ 10. The output will energize
when the rate equals 100 and de-energize when the
rate falls below 90 (10 below Preset).
Select “
PuL
” (pulse output) to use the output for remote
totalizers. When set to “
PuL
”, a minimum duration in
seconds (0.00 to 599.99) can be assigned to the time
the output will remain energized and de-energized. If
0.00 is chosen the relay or open collector is disabled.
The pulse output follows the total and the relay or open
collector will output a “pulse” on every multiple of the
Preset Setpoint. (ie. Preset is set to 10. A pulse will be
generated for total values 10, 20, 30, 40, ... , etc).
NOTE: If unit is setup to autorecycle then pulse output
should not be used.
