In Auto mode, is the front door safety switch monitored?

• A. Yes
• B. No
• C. Only during maintenance
• D. Not monitored at all

Answer: (A)

In Auto mode, the front door safety switch is monitored to ensure the machine cannot operate with the door open. The safety controller treats this switch as a live safety input, so if the door isn't closed, it immediately inhibits motion or triggers a safe stop. This constant verification is essential because opening the door during automatic operation could expose operators to moving parts. The idea that monitoring occurs only during maintenance or not at all would compromise safety, whereas continuous monitoring in Auto mode keeps the system safe and compliant.
