PD6830 Pulse Input Rate/Totalizer Instruction Manual
63
If automatic total/grand total reset is enabled, the output will generate an alarm for a
period of time programmed in ADVANCE  T RESET  Auto T DELAY. After this
time delay, the total/grand total will reset to 0 and the alarm will clear.
If Out 1 and Out 2 are set for total or grand total alarm, the auto reset will be triggered
on the highest of the two alarm set points.
For details on setting the total or grand total automatic reset time delay, see Total Re-
set (T Reset) on page 71.
Force On State (On)
This alarm mode forces the output to be active, or on. This mode is primarily used to
test alarm systems.
Force Off State (OFF)
This alarm mode forces the output to be inactive, or off. This mode is primarily used
to test alarm systems.
Timer Output (tmer)
The timer output produces a constant width pulse at a constant rate. Program the
Delay Period
for one period from 0.1 to 999999.9 seconds (time from the start of one
pulse to the start of the next pulse).
Program the On Time for the active low pulse from .01 to 99999.99 seconds (pulse
width). The on time must be less than the delay time.
Select Start to begin outputting the constant timed pulse.
Select Stop to end outputting the constant timed pulse.
Total Reset Output (t rst)
A total reset output generates a pulse whenever the selected total is reset, total or
grand total, regardless of the reset method used. Program the On Time from 0.10 to
99,999.99 seconds. This is the amount of time the open collector output will remain
on after the total or grand total has been reset.
