Repeat Cycle (
rCy
)
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
). At the end of the timing period, the timing period will
reset and repeat automatically.
If the output pulse width parameter (
tout1
) is set to 0.00 both outputs will turn ON at the end of the first timing
period, turn OFF at the end of the next timing period, turn ON at the end of the next timing period, etc.
If the output pulse width parameter (
tout1
) is set to >0.00 both outputs will turn ON momentarily for the time set
in the output pulse width parameter (
tout1
) at the beginning of the each timing period.
The trailing edge of the “start” signal has no effect on the outputs or timing period.
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 new “start” signal is
necessary to restart the cycle.
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 and the timing period will be reset.
