Connect the slave to the master unit with 2 core flex (maximum load 8Amp at 12volts) (Figure 3)
Figure 3: Master/Slave connections
The units are set in the factory for a standard installation with the master placed on the left hand side
(from inside looking out). If the master is to be located on the right then the motor wires need to be
reversed. To do this, locate the connection blocks for each motor on the circuit board. Swap the brown
and blue wires for motor one. Do the same for motor two (Figure 3)

The gate bracket should be positioned so that the arms are almost in a straight line when the gates are
closed (Figure 4) To check the location of the gate brackets, first disengage the main arm from the drive
shaft (using the spanner provided), unscrew the bolt until the arm swings freely. Clamp the gate bracket
in position. Open and close the gate to ensure the gate bracket is appropriately located.

The limit switches may now be adjusted (Figure 5). Each unit has its own pair of cams, one to set the
open position and one to set the closed position. Loosen the screw holding the cams. Operate the
operator with the transmitter and note which cam controls the opening/closing motion (the cam lobe
activates a limit switch to turn off the motor). Reposition each cam and operate the operator again.
Repeat until the gates open and close to the required positions.
