ADJUSTMENT ACCESSORY WIRING Field Wiring Terminals 9 & 5 - Obstruction Open (Edge/Photo Eye Input) Edge Input: See Programming Section This input will reverse an opening gate to the close limit. Activating this input when the gate is closing will have no effect. NOTE: If upon reversal a second separate obstruction is detected (gate edge or RPM sensor), gate will stop and alarm. Photo Eye Input: See Programming Section This input will pause an opening gate. Once the input (photo eye) is cleared, the gate continues to open. Activating this input when the gate is closing will have no effect. OBSTRUCTION OPEN (EDGE/PHOTO EYE INPUT) 5 8 9 10 11 12 Field Wiring Terminals 10 & 5 - Obstruction Close (Edge/Photo Eye Input) Edge Input: See Programming Section This input will reverse a closing gate to the open limit. When reaching the open limit the Timer to-Close, if enabled, will be disabled until another command is given. Activating this input when the gate is closing will have no effect. NOTE: If upon reversal a second separate obstruction is detected (gate edge or RPM sensor), gate will stop and alarm. Photo Eye Input: See Programming Section This input will reverse a closing gate to the open limit. This input will not affect the Timer-to-Close. Activating this input when the gate is closing will have no effect.

This input functions to stop the gate or to reset the gate after an entrapment fault. NOTE: This input uses a normally closed circuit and the operator will not run until a stop control is installed. STOP/RESET BUTTON WIRING R1 R2 R3 R4 3 5 OPEN CLOSE STOP STOP J1 Terminals 4 & 5 - Hard Close Control Input These terminals are intended for use only with the close control HARD CLOSE CONTROL INPUT of a three-button station that is installed within line of sight of the OPEN gate. A momentary activation of this input will cause the gate to 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 CLOSE close. Activation of this input for longer than three seconds will CLOSE STOP enable the control to be used as a constant pressure override device. This will allow the user, in emergencies, to override a failed accessory such as a loop detector or photo-eye.
