Mode K (

When the count present value PV counts down to the count
setting value SV1, Output 1 will turn ON momentarily for the
time set in the output pulse width parameter (tout1) or will be
maintained ON if the output pulse width parameter (
tout1
)
is set to 0.00. When the count PV counts down to 0, Output 2
will turn ON momentarily for the time set in the output pulse
width parameter (
tout2
). If Output 1 is ON when Output 2
turns OFF, Output 1 will also turn OFF. The count PV will
continue to decrement with each input signal.
The leading edge of a “reset” input signal at RST1 will turn
OFF both outputs, reset the count PV to the count SV2 and
prohibit an input signal from decrementing the count PV. The
trailing edge of the “reset” signal at RST1 enables counting to
begin.
The “reset” signal minimum pulse width is set by reset pulse
width parameter (
rtSr
) or DIP Switch 8.

Note: T1 momentary ON time set in output

When the count present value PV counts down to the count
setting value SV1, Output 1 will turn ON momentarily for
the time set in the output pulse width parameter (
tout1
) or
will be maintained ON if the output pulse width parameter
(
tout1
) is set to 0.00. When the count PV counts down to
0, Output 2 will turn ON momentarily for the time set in the
output pulse width parameter (
tout2
). The count PV display
is prohibited from decrementing until the end of the output
pulse time (tout2) when both outputs turn OFF and the count
PV is reset automatically to the count SV2 and any input signals
that occurred during the output pulse time.
The leading edge of a “reset” signal at RST1 will turn OFF both
outputs, reset the count PV to the count SV2 and prohibit an
input signal from decrementing the count PV. The trailing edge
of the “reset” signal at RST1 enables counting to begin.
The “reset” signal minimum pulse width is set by reset pulse
width parameter (
