Signal Cumulate (
SCon
)
With power applied to the CTT, the leading edge of
the input signal at START will begin the timing period
setting value SV timing up or down based on parameter
(
t modE
). The trailing edge of the “start” signal will
pause the timing period. The leading edge of a subse-
quent “start” signal will resume timing from the last
value of the timing period. At the end of the timing
period both outputs will turn ON.
The leading edge of a “reset” input signal at RST1 will
turn OFF the outputs and reset the timing period. The
“reset” signal minimum pulse width is set by reset pulse
width parameter (
rtSr
).
The leading edge of a “pause” input signal at GATE will
pause the timing period after it has been started. The
timing period will continue after the trailing edge of the
external switch “pause” (Gate) signal.
When power is removed, both outputs will turn OFF.
The last state of the outputs and the last value of the
current timing period will be “stored” when power is
removed. When power is reapplied the outputs will
return to their last state and timing will resume from
the last value of the timing period by the leading edge of
a new “start” signal.
