Features
Electronic Reversing Device (ERD)
The Electronic Reversing Device (ERD) is a feature on the circuit board which detects when the gates
comes in contact with an obstruction, causing the gate to reverse.
The open and close knobs determine the amount of force required to reverse the gate (figure 22). We
generally recommend leaving the knob at 75, or around a 3:00 position. You may adjust the positions based
on your needs.
If the gate reverses without touching an obstruction, the ERD is too sensistive. If the gate does not reverse
when it hits an obstruction, the ERD is not sensitive enough.
