In a soft shutdown, what minimum movement occurs before the gate reverses after sensing an obstruction?

• A. 2 inches
• B. 2 degrees
• C. 2 feet
• D. 2 centimeters

Answer: (A)

Soft shutdown means the gate slows and reverses when it encounters an obstacle, but only after it has moved a short distance. This small forward travel gives the system a moment to confirm the obstruction and engage the safety sensing before reversing, which makes the stop smoother and safer and reduces the chance of false reversals from minor sensor glitches or brief contacts. The typical minimum is two inches of gate movement before reversing, because this distance is enough to ensure the obstacle is truly engaged and to provide reliable reversal without overextending the gate or risking damage. Distances expressed in other units like degrees don’t apply to the linear travel of the gate, and uses of much longer or much shorter distances would either hamper safety or cause unnecessary reversals.
