Mode N (

)
When the count present value PV counts up or counts down to
the count setting value SV1, Output 1 will turn ON momen-
tarily 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
up to the count SV2, Output 2 will turn ON. The count PV
will remain at the count SV2 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 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 “reset” signal minimum pulse width is set by reset pulse
width parameter (
rtSr
) or DIP Switch 8

Mode C (

When the count present value PV counts up or counts down to
the count setting value SV1, Output 1 will turn ON momen-
tarily 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
up to the count SV2, Output 2 will turn ON momentarily for
the time set in the output pulse width parameter (tout2) and
the count PV will reset automatically to 0. 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 0 and prohibit an
input signal from incrementing or decrementing the count PV.

Mode R (

)
When the count present value PV counts up or counts down to
the count setting value SV1, Output 1 will turn ON momen-
tarily 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
up to the count SV2, Output 2 will turn ON momentarily for
the time set in the output pulse width parameter (
tout2
). The
count PV is prohibited from incrementing or decrementing
until the end of the output pulse time (
tout2
) when both
outputs turn OFF and the count PV is reset automatically to 0.
The leading edge of a “reset” input signal at RST1 will turn
OFF both outputs, reset the count PV to 0 and prohibit an
