Mode N (
n
)
The Total PV increments with each decrement of the count
present value PV. When the count present value PV counts
down to 0 both outputs 1 and 2 will turn ON. The count PV
will remain at 0 regardless of additional input signals.
The leading edge of a “reset” input signal at RST1 will turn
OFF both outputs, reset the count present value PV to the
count setting value SV, and prohibit an input signal from decre-
menting the count PV. The trailing edge of the “reset” signal at
RST1 enables counting to begin.
The leading edge of a “reset” input signal at RST2 will reset the
Total PV to 0, and prohibit an input signal from incrementing
the Total PV. The trailing edge of the “reset” signal at RST2
enables counting to begin.
The “reset” signal minimum pulse width is set by reset pulse
width parameter (
rtSr
) or DIP Switch 8.

The Total PV increments with each decrement of the count
present value PV. When the count present value PV counts
down to 0 both outputs 1 and 2 will turn ON momentarily
for the time set in the output pulse width parameter (
tout2
)
and the count PV will reset automatically to the count setting
value SV.
The leading edge of a “reset” input signal at RST1 will turn
OFF both outputs, reset the count present value PV to the
count setting value SV, and prohibit an input signal from decre-
menting the count PV. The trailing edge of the “reset” signal at
RST1 enables counting to begin.
The leading edge of a “reset” input signal at RST2 will reset the
Total PV to 0, and prohibit an input signal from incrementing
the Total PV. The trailing edge of the “reset” signal at RST2
enables counting to begin.
