ETAILS
After reading the previous sections in this manual, and having checked for suitable installation,
proceed as follows:-
Electrical Cabling
•
A suitably rated Isolator and 240v non earth leakage protected power supply should be available near to where the
gate operator control box is to be mounted.
•
Mains voltage and low voltage cabling (see wiring requirements) needs to be run from control box to gate
operator, in separate conduits preferably to come up along side the base plate, within area of the cover.
•
Magnetic Lock wiring – A low voltage 4 core cable will be needed to run from the control box position up to the
centre of the fixed closing post.
•
Any other safety protection wiring e.g. P.E. Cells and Induction Loop cabling needs to be wired.
•
Input control cabling and output signal wiring also needs to be in place.
Mechanical Installation
•
Ensure gate rolls easily and has been installed in a manner where there is no excessive friction or binding
occurring.
•
A concrete base approximately 600mm long x 300 wide x 300mm deep should be laid where the gate operator is to
be located.
•
IMPORTANT ensure there are gate stops firmly installed in the fully open and closed positions. These stops need
to be engineered and installed such that they will be strong enough to stop the gate should the limits fail at any
time.
•
Remove the gate operator cover and position mounting plate and operator in approximate mounting location.
•
Use the rack to locate the operator the correct distance away from the gate rail (finer adjustment can be made after).
•
Dynabolt or chemical anchor the bottom mounting plate to the concrete mounting pad using 12 x 100mm fixings.
•
Unscrew anticlockwise the manual disconnect nut so the drive gear free wheels.
•
Fix the rack to the gate rail ensuring there is approximately 1mm - 2mm gap between the meshing of the teeth of
the rack and the drive gear (no more). Move the gate by hand from one end to the other while checking that the
rack is meshing correctly with the drive gear on the operator. Check also that the rack is centred around the
middle of the teeth on the drive cog – tighten the mounting plate nuts.
Electrical Connections

PERATORS
:-
•
20mm conduit for mains voltage and conduit for low voltage cabling can enter from either side (see cut out
positions on cover) or preferably through the base plate spacing between plate & cover.
•
Wire the mains voltage cabling from the inverter, straight to the motor terminals and connect both the shield and
earth to the earth terminal.
•
Wire the low voltage limit switch cables to the limit switches. If the cabling run is over 8m, connect the shield to
the earthed chassis.
•
Note which cam will be used to act as the open position cut off and the close position cut off. Wire the
appropriate cam switch to the appropriate limit switch terminal on the control board.
•
One side of the cam switches are commoned and wired back to the limit switch common terminal on the control
board.
