The Electronic Reversing Device (ERD) is a feature on the circuit board which detects when the gate 

comes in contact with an obstruction, causing the gate to reverse. These are the 2 blue knobs on the 

circuit board.

The open and close knobs determine the amount of force required to reverse the gate (figure A). We 

generally  recommend  leaving  the  knob  at  50.  You  may  adjust  the  positions  based  on 

your particular gate.

If the gate reverses without touching an obstruction, the ERD is set too low. If the gate does not 

reverse when it hits an obstruction, the ERD is set too high.

Test ERD every 6 months.

Normal

 

= 50 is the default ERD force and is suitable for most 

gates

Turn Left/Counter-Clockwise 

= Less force to stop the gate. 

Turn Right/Clockwise

 

=  More Force required to stop the gate. 

WARNING

Never increase force beyond the minimum amount required to move the gate. Too much force may

seriously injure or kill people.

Never use force adjustments to compensate for a improperly installed, improperly maintained, or a

damaged gate. The gate must normally move freely with no obstructions.

The ERD must be tested after making any changes. The gate must reverse when it comes in contact

with an object.

Obstruction Test

1. Place a light object (ex. chair or trash can) between the open gate and the post.

2. Close the gate. The gate should stop and reverse when it touches the object. If the

gate does not reverse when it touches the object, press the STOP button on the circuit

board. Reduce the ERD force by turning the CLOSE ERD knob counter-clockwise.

3. Do the same test again for the open direction.

4. Test the gate operator after any adjustments are made.

Step 8: Force Adjustment
