Mode Q (
q
)
When the count present value PV counts down to 0 both outputs 1
and 2 will turn ON momentarily for the time set in the output pulse
width parameter (
tout2
). The count PV will continue to decre-
ment with each input signal until the end of the output pulse time
when the outputs turn OFF and the count PV is reset automatically
to the count setting value SV.
The leading edge of a “reset” input signal at RST1 will turn OFF
both outputs, reset the count PV to the count SV 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.
Mode A (
A
)
When the count present value PV counts down to 0 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 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 setting value SV 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.
