Signal On (

)
With power applied to the CTT, the leading edge of the input
signal at START will immediately turn ON the outputs and begin
the timing period setting value SV (timing up or down based on
parameter (
t modE
) or by DIP switch 2). The trailing edge of
the “start” signal has no effect on the outputs or timing period.
At the end of the timing period both outputs will turn OFF and
the timing period will reset. The leading edge of a “start” signal
applied during a previously initiated timing period will not reset
the 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
) or DIP Switch 8.
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.
