1. GATE MECHANICS

BEFORE INSTALLING

BEFORE ATTEMPTING TO INSTALL A SLIDE GATE OPERATOR,

a) Gate Leaf

Gate leaf must be sound and of suffi cient construction

to withstand an operator of this type (see technical
specifi cations).
Gate leaf should be straight and true with minimal
deviation to the facia that the rack must attach to (no
banana-effect).
b) Wheels

Recommended wheel type and size for this automation is

steel or steel alloy, machined or cast wheels of at least 100mm
diameter using sealed roller bearings (see next page).
For wheel profile, see the three types below:

e) Track

Note the recommended track type in fi gures on page 7.

The track must be secure, straight, level and free of all obstructions. Install physical stopper at the ends of the gate travel to
avoid the gate over-running the ends of the track as shown in
figure 8.2.

d) Gate Travel
Using a fish-scale, as shown below, pull the gate fully open
and fully closed. For optimum duty cycle, ensure that the
maximum resistance at any point does not exceed 10kgF.

Before mounting the operator ensure your cabling and conduiting are in
place to prevent any inconvenience at a later stage. Allow for spares in
case of faulty cable & breakages (especially important when using
low specifi cation cable). If installing an intercom, remember to allow for
sufficient cable cores for all the uses on the system as per manufacturers
cabling requirements.

Alternative to STEP 1:
Fasten the mounting plates to the main motor
mounting points, as shown here.
This must be done on both sides of the motor.
In the case of the motor butting up against a
guide post: on the guide post side of the motor
use the upright bar, as shown in the line drawing
Fig 12.1 overleaf, by first inserting it into the
mounting plate before fastening it onto the motor
mounting point as shown here.

Figure 11.2

STEP 2:
When the installation of the motor is complete,
slide the side vent covers into the slots on either
side of the gearbox. Then fasten the cover onto
the gearbox using the four stainless steel screws
supplied. Slide the bent theft-deterent bracket into
its mounting plate and swing it across the motor, so
that the bracket rests in the moulded slot on top
of the cover. Ensure that the hole in the upright
theft-deterent bracket and the hole in the bent
theft-deterent bracket are aligned, where the two
brackets meet.

Take note of the lock position when installing the motor next
to the guide post and remember to insert the short bracket
into its mounting plate, before fastening the the mounting
plate in position.

Before mounting the gearbox on a base plate that has been newly cast,
ensure that you have allowed sufficient time for the concrete to set and cure as
movement will detrementally affect the sturdiness of your motor fixings.
Please note:
When positioning the gearbox, you should allow a minimum of 5mm between
the facia of the pinion and the facia of the gate leaf so as to avoid the gate leaf
scraping against the pinion.
Use the 2 x M8 nylock nuts with 2 x 8mm flat washers to fasten your gearbox to the
base plate.

STEP 4 - ADJUSTING MOTOR FINAL POSITION

Refer back to figure 8.2 on page 8.
Now that you have completed the mechanical installation, before proceding
with programming and set up, double check the gate load with the operator
manually released.
Pull the gate through its full travel, open and closed, to check that the gate is
not snagging or the rack is not riding up of the rack on the pinion.
Your gate should not exceed 10kgF with the motor in final position to obtain
the optimum duty cycle.

Your hardware is now installed. Proceed to wiring and programming.

PROGRAMMING

To program a users transmitter into the Ped pedestrian opening option:

If a transmitter button has been learnt into the incorrect function, it must be deleted
from that function first to be able to learn it into the correct option.

To erase an individual transmitter button without interfering with memory allocated to other users on the receiver:

NOTE: The following is carried out with power present at all times.

1.

Short all three receiver-programming pins (Bt Middle Ped) together.

Hot tip: - You can use a key ring supplied with transmitter to do this.

2.

Press and hold the transmitter button you need to erase from the receiver memory.

3.

When RX LED begins to flash release transmitter button and remove

short.

Repeat to erase additional transmitter buttons.

The button used for Bt cannot be used for PED and visa versa (The LED will not flash
confirmation if you try this)
Only one button per transmitter can be learnt into an input.

When auto-close is activated and the gate
opens to the open limit, the unit will wait the preprogrammed time (see 2-Auto-close on page

triggered while the gate is in its closing cycle it
will stop and re-open.
To override the auto-close, wait until the gate
reaches its open limit then press and hold the
