The open collector and relay outputs trigger when the
total or rate (assignable; see programming step 2)
equals the corresponding Preset (A or B).
When the outputs are assigned to the "total", the opera-
tor can assign a duration of time (.01 to 599.99 sec.) that
the output will remain energized. If 0.00 is assigned, the
output will latch until reset. If output A is set at a duration
(other than 0.00), the totalizer will autorecycle when
Preset A is reached. At this time, output B will de-
energize (if it was energized). Preset A is the final
preset and should be set higher than Preset B, when
both outputs are assigned 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 assigned to total). The totalizer will never
autorecycle at Preset B.
When the outputs are assigned to the "rate", the outputs
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).
NOTE: If the input scaling is inverted, the control output
functions are inverted (LINEAR ONLY).
