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.

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.

2.1 Cabling
A typical installation requires to following cables. Conductor size
is the minimum recommended based on current. Cable insulation
must be suitable for the run. Underground cables and cable
exposed to UV light must be rated accordingly.

Alarm or data cable
The motor cable enters through the fixing plate. It can
be ducted up the pier, or neater still, run thru the pier.
The RETRO is a useful housing to make connections to
pier mounted devices such as photo-beams, safety
edges & access controls, so it is good to run a low
voltage cable. Wiring and programming is covered in
another document.
The control panel
can be mounted on
either pier, or on a
nearby wall.
Mounting it inside
a nearby garage, is
recommended for
security, and
protection from
harsh weather.
2.2 Setting limit switches
Manually release and set the gate in the fully open position. The
right motor with the cams on top is the easiest to set. Release the
lower cam with a hex key, then slowly rotate the lower cam anti-
clockwise until you hear the micro switch click. Lock the cam by
hex key on the easiest grub screw.
Move the gate to the closed position. Release the upper cam with
a hex key. Slowly rotate the upper cam clockwise until the micro-
switch clicks. Lock the upper cam with the hex key.
Repeat the cam setting on the other motor. You may need to adjust
cams when the gates are under power. Finish the commissioning
process, then come back again to tighten the grub screws. There are
two grubs per cam. Access them by turning the arm and gate until
the hole becomes accessible.
Finally screw the covers on with four screws thru the locking door.

Manual release
In the event of power failure, the RETRO motor can be manually
released from the gate. Use the key to open the RETRO door. Turn
the silver handle inside anti-clockwise to release.
Maintenance
Check the following every 6-9 months. Grease all arm joints.
Ensure arm and motor mounting bolts are tight. Check cables are
securely terminated. Operate each safety device in turn to check
correct reversal.
Safety warnings
Automatic gates can be hazardous. It is the operators responsibility
of an automatic gate to be aware of, and provide adequate warning
of hazards. All users should be given a hazard awareness briefing
and user training for the automatic gate.
This manual is written for automation engineers aware of the construction and
accident prevention rules in force. Only qualified persons may do installation or
maintenance work on this installation. Keep the gate in good working order with
regular checks on the safety devices fitted.
Operators should ensure people are clear of the gate during operation. Children
must not be allowed to play on or near the gate, or be allowed to operate the
gate. We recommended signs both sides of the gate to warning of risk of injury
to pedestrians. Do not permit public access to the gate area.
WARRANTY
3 year return to base warranty covers defective manufacture and material. The warranty does not cover
accidental damage, misuse, or abnormal wear. Warranty is conditional on good installation, maintenance and
service recommended in this manual. Warranty is void if subject of unauthorised modification or repair, or
abnormal input voltage. This does not affect your statutory rights
