Master/Slave Wiring
AGS 3000 MASTER/SLAVE
Connect 115 Volts AC to each AGS 3000 gate operator. Connect the six Master/Slave wires from the master circuit board
to the slave circuit board as shown below. Any operator can be used as either a master or a slave. All accessories will be
connected to the master operator so the decision of which operator will be the master and which operator will be the slave is
a matter of convenience. If it is more convenient to run accessory wires to one operator than to another, choose that particu-
lar operator which is most convenient to be the master so that the wires can be run in the easiest manner possible.
Switch the Auto Close Timer switch to the OFF position on the slave circuit board. The Auto Close Timer switch on the
master circuit board may be switched either ON if the timer function will be used or OFF if the timer function will not be used
but the slave timer must always be switched OFF.
If the chain is wrapped around the sprockets in the same manner on each operator (both chains under or both chains over
the drive sprocket) set the Right/Left Side Operation switch on the master circuit board to be the opposite of the way it is set
on the slave circuit board. If the chain wrapped around the drive sprocket on the master operator is the opposite of the way it
is wrapped around on the slave operator then set the Right/Left Side Operation switches the same on both operators. The
Right/Left Side operation switch is located on the circuit board. If the operators are working backwards, the Right/Left Side
Operation switches on both operators must be switched. The simplest way to know if the operators are working backwards is
to turn the Auto Close Timer switch on the master circuit board to ON and see whether the timer works when the gate is
open or closed. The timer should work only when the gate is open. Another way to know if the operators are working back-
wards is to try the gate sensitivity by applying pressure against the gate while the gate is opening or closing. If pressure is
applied while the gate is opening it should stop. If pressure is applied while the gate is closing it should reverse and go open.
If the gate responds to pressure in a way that is opposite of this then switch the Right/Left Side Operation switch on both
operators.
