Mode N (
n
)
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. 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 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.

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
) and the count PV will reset auto-
matically to the count SV2. If Output 1 is ON when Output 2
turns OFF, Output 1 will also turn OFF.
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

Mode R (

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 is prohibited from
decrementing until the end of the output pulse time (
tout2
)
when both outputs turn OFF and the count PV is reset auto-
matically to the count SV2.
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.
