When jogging in T1 Test mode, the front door safety switch is monitored.

• A. True
• B. False
• C. Depends on the machine
• D. Not monitored

Answer: (B)

In T1 Test mode, the control system disables monitoring of certain safety interlocks to allow manual jogging and setup. The front door safety switch is one of these interlocks that is not actively monitored during this mode, so opening the door will not trigger a safety shutoff while jogging. Because monitoring is turned off in this mode, the statement that the front door safety switch is monitored is not correct. In normal operation, the door safety switch is monitored to ensure the machine stops if the door opens, preserving safety outside the test context.
