If the deadman switch is released by the operator or pressed too hard by the operator a fault occurs that has to be reset.

• A. True
• B. False
• C. The fault is automatically cleared
• D. It triggers a fault that must be reset

Answer: (D)

The deadman switch acts as a safety input that must stay engaged to keep the robot enabled. If it’s released or pressed too hard, the controller sees an unsafe or abnormal condition and latches a fault. This fault is not cleared automatically; it requires an explicit reset so you acknowledge the issue and can verify it’s safe to resume operation.
