Timer Example - Automation Direct CTT-1C-D24 Manual

Timer Example:

A basic Timer used to control a clamp time of a compression model press. When the operator signals the
mold is loaded with material by pressing the start button the hydraulic cylinder closes the press to make a
limit switch which starts the CTT timing. Upon completion of the timer cycle Output 1 is turned on and
the press is opened by the hydraulic cylinder.
Signal On Delay 1 ( Sond1 )
With power applied to the CTT, the leading edge of an input signal at START will begin the
timing period setting value SV timing up or down based on parameter ( t modE ) or by DIP Switch 2. At
the end of the timing period both outputs will turn ON momentarily 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. The trailing edge of the "start" signal has no effect on the outputs or timing period. The leading
edge of an "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 an input "pause" signal at GATE will pause the
timing period after it has been started. The timing period will continue after the trailing edge of the
"pause" (Gate) signal. When power is removed, both outputs will turn OFF and the
timing period will be reset.
