Installation
Emergency stop (E-stop) connection
Sample E-stop circuit
Figure 20 illustrates an example of an E-stop that a table manufacturer might implement. The CPC for this circuit
connects to the E-stop connector on the rear enclosure of the CNC and to the built-in safety circuit within the EDGE Pro
Ti CNC, shown in Figure 21.
The E-stop in Figure 20 uses Hypertherm components; an E-stop switch (428025), safety relay (003239), and reset
switch (428026) and uses the EDGE Pro Ti E-stop cable to connect to the safety circuit within the CNC. Other
components require a different design.
