A safer practice is to use electromagnetic safety door switches so that when the safety door is closed,
the safety switch generates a magnetic force to keep the door lock bolt securely in place. This prevents
workers from accidentally opening the door and entering the railing, and protects them from danger.
You can install the power switch for the electromagnetic safety door lock inside the railing so that when
workers are accidentally trapped inside the railing, they can turn off the power switch to release the
electromagnetic safety door. Figure 5.22 shows the installation method.

5.2.7 System. DI/O

The DCV controller has a standard D-Sub 25-Pin/Female Connector. The System DI/O connector
provides seven input points and eight output points to communicate with the upper controller (such as a
PLC). Table 5.3 lists the pin definitions.
