Inputs
Figure 30 shows a simplified schematic of the ArcGlide THC inputs.
The inputs for both CNC and plasma can be configured for dry
contacts (no external voltage) or for positive voltage sourced inputs.
The default is dry contacts. The inputs have two different modes that
are selected using switches behind the calibration and setup door on
the top right front of the control module.
The mode that is selected automatically compensates for the polarity
reversal so that in both cases, a closed switch input will activate the signal.
All inputs to the lifter interface and operator console interface are fixed in the dry contact mode.
