WIRE ACCESSORIES TO CONTROL BOARD Photoelectric Sensors and Edge Sensors The EYES/EDGE terminals are used for connecting entrapment protection devices. At least two external monitored entrapment protection devices are required prior to gate movement; one in the open and one in the closed direction. Monitored entrapment protection devices should have been installed with the operator at the time of installation. Only ONE monitored device may be connected to each input. A monitored device sends a pulsed signal to the operator so the operator is aware of the device. If the operator does not receive the signal from the device indicating it is working properly, it will not run in that direction. TERMINALS CLOSE EYES/INTERRUPT CLOSE EDGE OPEN EYES/EDGE FUNCTION The CLOSE EYES/INTERRUPT input is for close direction photoelectric sensors. When an obstruction is sensed during gate closing the gate will open to the full open position. This input will be disregarded during gate opening and resets the Timer-to-Close. The CLOSE EDGE input is for the close direction edge sensors. When an obstruction is sensed during gate closing the gate will reverse to the full open position, disengaging the Timer-to-Close. This input will be disregarded during gate opening. The OPEN EYES/EDGE input is for open direction photoelectric sensors or edge sensors. When an obstruction is sensed during gate opening the gate will reverse for 4 seconds then stop. This input will be disregarded during gate closing. WIRING EXAMPLE Locks TERMINALS NC and COM FUNCTION Normally Closed (N.C.) output for maglocks. Relay activates prior to motor activation and during motor run. Relay is off when motor is off.
