[. . . ] When released gate will close if closing timer is on or if close input is given. Terminal 4, Auxiliary Open - This is the wired line of sight, intended manual reset input. Use this input to reset the unit after a 2nd sequential obstruction is sensed and gate is locked with siren running. This input normally functions as listed below. Acts same as 1, 2, 3 above with S2-6 off. With S2-6 ON this will operate as a pulse-open, pulse-close. NOTE: Pulse to close will only work when gate is at full open position. SIREN will run for 5 minutes after 2nd sequential obstruction, then turns itself off, however operator will require a reset signal to J5 #4 to re-activate gate. In addition, cycling the ac power will also reset unit. Terminal 5, Safety - Safety edge(s) and safety loop input. This function will make the gate reverse and go back to the open position if it was closing. Input is for all NORMALLY OPEN contact safety devices. This input is disabled when gate is in the full closed position. Use with vehicle loops, photo beams and sensors. Terminal 6, Close - ANTI-TAIL GATE close input. When using a vehicle detector, you must use the presence contacts (N. O. and C. ) This input will QUICK close gate after input is applied and then removed. It will stop the open cycle and reverse gate to close. (Example: Car crosses over close loop before gate reaches full open position ­ gate will reverse and close). NOTE: The close input also acts as a safety-stop in that if gate is closing and a tail-gater is sensed at the close input, the gate WILL STOP its closing motion and not continue to close until the close input is removed or gate is re-opened. Terminal 7, Back-Away (For Barrier Arm Gate Only) - This input is recommended for use with our Mega Arm barrier gates. For your Mega Slide X, please use terminals 1, 2 or 3 for your free exit loop input. Terminal 8, Shadow Loop - This input operates as a hold open only when gate is a full open position.
