1.0 Installation

The RETRO is a simple to fit articulated arm motor for gate
leaves up to 2.5m. RETRO is ideal for fitting to existing gates, or
onto brick piers where ram geometry is not suitable.
Articulated arm motors have a geometric slow down in open
and close positions that suits control of heavy gates. Read and
observe the safety warnings before starting.
There is no need for gate centre or open stops because the
RETRO is fitted with open and close limit switches. Motors can
be fixed at any height, but it is good practice to fit the gate fixing
bracket to a strong horizontal rail.

1.1 Gate geometry

Check that the RETRO is suitable for your application before
unpacking the set. Geometry is not critical, but check first.
The back of the pier must be less than 350mm (Y) from the gate
line. In the open position, the arms may also foul the wall, so
allow for (W) space. If you have long hinges the motor plate may
need to overlap the edge of the pier.

1.3 Assemble to pier

Fit the motor to the plate. Manual release it.
Then attach the arm with the vertical screw.

1.2 Motor plate fixing

The motor has a detachable fixing plate which needs to be
securely fixed to the pier. RETRO geometry is not critical so you
can choose the pier position for fixing strength. Avoid mortar and
soft bricks. Use the correct fixings for the pier material.
If the X dimension allows, set the motor plate to the edge of the
pier. Fixing plate height is set (Z) above the gate fixing bracket
centre line.
'Z'
= 35mm

1.4 Gate fixing bracket

Clamp the gate bracket on. The angle should be 100°-120° in the
closed position. Swing the gate open. Ensure the arm doesn't
touch anything. The two arms should be no closer together than
parallel in the open position. If all is correct, close the gate and
bolt on the gate bracket.
