Step 2

Note

Connect the wires to the control board

When powering any accessories from the board, (for example: gate latches, additional receivers, keypads, and PE beams) ensure the power supply has adequate capacity.

Measure the voltage at the DC IN under full motor load. If it falls below 9V then the board, receiver, and some accessories, may not function correctly. In this instance, remove accessories, upgrade the power supply, or provide additional power supplies directly to each accessory

Step 3

Connect the wires to the motors

Motor 1 is the left hand motor when facing out of the driveway.

If motor 1 is on the right hand side, reverse the polarity of the motor wires.

If a single motor is fitted use the Motor 1 terminals. If a single opener is fitted on the right hand side, reverse the polarity of the motor wires.

If a motor pushes a gate outwards, reverse the polarity of the motor wires.

Step 4

Control board set up.

Operate the gates by either a remote control or a push button.

The travel timer pot controls the operators. Adjust the timer so that the motor/s complete their full open and close cycle plus an extra 3 seconds of travel time. the motor clutches will slip and make a clicking sound during this period.

Note

Reverse motor wires if open and close LED’s do not match gate travel.

Step 5

Set clutch torque level

There are two hex nuts on the under side of the motor housing. These are factory set at approx 20kg and may not require adjustment.

When the gates reach its stops the clutch should slip untill the control board deactivates.

Note

The same adjustment should be made to both screws

I.e.: if one nut is adjusted 1 turn clockwise, the other must have the same adjustment.
