Mode Q (
q
)
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 will continue to increment or 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 auto-
matically 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
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.

Output Mode Q
Note: T1 momentary ON time set in output
pulse parameter (tout1), setting tout1=0.00
results in output 1 maintained ON.
T2 = Momentary ON time set in output pulse
parameter (tout2).

(

up to the count SV2, Output 2 will turn ON momentarily for
the time set in the output pulse width parameter (

). 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

Mode S (

When the count present value PV counts up to the count setting value SV1 Output 1 will turn ON. When the count
PV counts down to the count SV1 Output 1 will turn OFF. When the count PV counts up to the count setting value
SV2 Output 2 will turn ON. When the count PV counts down to the count SV2 Output 2 will turn OFF. The count
PV will continue to increment or decrement with each input signal.
