sensing) output logic is inverted – output turns off upon sensing the plate (refer to
Section 3.16).
I-TAC: When enabled (
inverted – output is off when arc is on (refer to Section 3.16).
Arc Hold: When enabled (
CTP functions are initiated as normal, but an arc is not initiated. Arc Hold is released
by removing the Start Command and reasserting – the Start Command must be
removed for a minimum of 10ms before reasserting. Upon reasserting the Start
Command, the arc will be initiated.
The Arc Hold feature can only be used with DES (refer to Section 4.2.4).
Time To Start (TTS) is the length of time in milliseconds (ms), upon removal of the
Start Command, after which the System will revert to the ready state if the Start
Command has not been reasserted. The Start Command must be reasserted within
9.5 seconds of initial receipt otherwise the System will revert to the ready state.
Removal of the Start Command after reasserting (releasing arc hold) will terminate
