Mode A (

)
The Total PV increments with each increment of the count
present value PV and decrements with each decrement of
the count PV. When the count present value PV counts up
to the count setting value SV both outputs 1 and 2 will turn
ON momentarily for the time set in the output pulse width
parameter (
tout2
). The count PV will remain at the count SV
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 0, and
prohibit an input signal from incrementing or decrementing
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
or decrementing 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 increment of the count present value PV and decrements with each decrement of
the count PV. When the count present value PV counts up to the count setting value SV both outputs 1 and 2 will
turn ON. When the count PV counts down to the count SV both outputs 1 and 2 will turn OFF. The count PV will
continue to increment or decrement with each input signal.
The leading edge of a “reset” input signal at RST1 will turn OFF both outputs, reset the count present value PV to 0,
and prohibit an input signal from incrementing or decrementing 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 or decrementing 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 (
