Which action completes the reset sequence for a chain failure alarm?

• A. Correct the cause of the alarm
• B. Create and release a different chain failure
• C. Press Menu
• D. Press F4 RES_1CH

Answer: (D)

When a chain failure alarm is active, the system expects you to clear the latched alarm with the dedicated reset control on the teach pendant. The key labeled RES_1CH on the F4 function is specifically designed to reset the first chain alarm. Pressing this clears the alarm latch for that chain and allows operation to resume once the situation is safe and any necessary checks have been completed.

Addressing the cause is important for preventing recurrence, but it does not, by itself, clear the current alarm state. Creating and releasing a different chain would introduce another alarm and won’t clear the one that’s already active. Navigating through the menu doesn’t reset the alarm state either. The correct action is the reset control that directly clears the first chain alarm.
