Mode Q (
q
)
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 will continue
to decrement with each input signal 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.
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

2 will turn ON momentarily for the time set in the output
pulse width parameter (
tout2
). The count PV will remain at 0
regardless of additional input signals.
The leading edge of “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.
