BEFORE ATTEMPTING TO INSTALL A SLIDE GATE OPERATOR, PLEASE BE CERTAIN YOU HAVE READ AND
UNDERSTOOD THE FOLLOWING TO ENSURE CONTINUED SATISFACTORY SAFE SERVICE FROM THIS PRODUCT:
The following are points to note before installing your new slide gate operator:
1. Gate mechanics
2. Cabling requirements
GATE MECHANICS
a) Gate Leaf
Gate leaf must be sound and of sufficient construction to accommodate an operator of this type (see technical specifications).
Gate leaf should be straight and true with minimal deviation to the fascia that the rack must attach to (no ‘banana-effect’).
b) Wheels and track
The track must be secure, straight, level and free of all obstructions.
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. The larger the wheel the less rolling resistance generated. Larger wheels also maintain their plumb and momentum
longer. When wheels are fixed in the gate, and not able to pivot, binding can occur if the gate is bowed (banana effect) For wheel profile
and matching track types, see the three examples below:
Recommended Less problematic Problematic
c) Guides
It is recommended that a roller guide consisting of a sealed roller bearing clad in nylon be used.
The guidance system should be installed at the top edge of the gate whenever possible. In cases where this is not possible the
guidance system should never be below the halfway point of the total gate height when the gate is in position on it's track.
In the case of a single guide roller running in a guide channel, ensure the guide never touches both inside walls of the channel
simultaneously. This causes the roller to snag as it tries to roll in both directions at once.
In the case of 2 guide rollers being used on either side of the gate leaf, ensure that both wheels never touch the leaf
simultaneously.
Avoid using more than 1 guide roller on the same side of the gate leaf to prevent binding.
As with the wheels the larger the guide the less rolling resistance generated.
d) Gate Travel
Using a fish-scale, as shown below, pull the gate fully open and fully closed at approximately the same speed as the operator you intend to
use (see technical specifications). For optimum duty cycle, ensure that the maximum resistance does not exceed 10kgF starting and 6kgF
running. The starting resistance should fall away within 300 to 500mm. Note the recommended track, wheel and guide types mentioned b)
and c) above.
NB! Install physical stoppers at the ends of the gate travel to avoid the gate over-running the ends of the track - as shown here. (National
safety standard requirement)

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

Install the base plate on the protected side of the driveway wherever possible. (opposite side of the guide post to the driveway) The base
plate must be installed 30 to 50mm away from the proudest part of the gate. The wheel bolt is the proudest part of the gate here. If in doubt
rather install the base plate further away and use spacers between the gate fascia and the rack when installing the rack.

Inserting and removing the battery
Fastening the operator to the base plate
Fasten motor to the base plate using the bolts and plates from the top as
shown here
Be careful that the cables are
not trapped and damaged
when fastening or adjusting the
motor on the base plate
Please note! In the cases where something like
the gate guide post or a wall is obstructing the
battery from being angled to one side, making
it impossible to insert or remove the battery
then carefully remove the control card and
control card holder before removing the
battery.
Remember to ensure the control card and
holder are both secured in place correctly
when finished.

Installing the rack.
Rack to pinion spacing. Correct.
The driving surfaces of each tooth
are 1 to 2mm apart. Allowing for
slight variance in the height of the
rack when the wheels shrink in
colder conditions or where the
gate flexes and the rack is no
longer square to the pinion.
Rack to pinion spacing.
Space to large.
This will cause skipping at the
slightest resistance to the gate
travel, resulting in the motor
control going out of
synchronization to the gate
position. (Losing open limit) The
long term damage here will be
stripped teeth.
Rack to pinion spacing.
To tight.
This will cause unwanted rolling
resistance especially in colder
conditions. Where the wheel
shrinkage will cause the gate to sit
heavier on the pinion or the rack is
no longer square to the pinion due
to gate flex.(False safety sensing
activation)
Begin by fastening the motor atop the base plate with 2mm spacer plates between.
Spacer plates
Clamp the end of the first length of rack end to the closing edge of the gate. Rest the other end
of the length on the pinion as shown here. Use a spirit level to ensure the rack remains true.

If satisfied with the rack level fasten the first “TEK” screw (supplied) in the middle of the slot
nearest the closing edge of the gate.
Move the gate towards the open position. Far enough that you can access the last mounting slot
at the opposite end of the length of rack to the end already fastened. Fasten the next “TEK”
screw here while the rack still rests atop the pinion.
To install additional lengths of rack, move gate closed until the next length of rack meets the first
length and the opposite end once again rests on the pinion. To ensure the 2 lengths of rack
marry correctly use an off cut of rack clamped upside down across the join of the 2 lengths.
Continue to fasten the “TEK” screws as before.
When finished installing sufficient rack to allow for the full travel of the gate plus enough to allow
for the limit actuator (as shown in the next section) remove the spacer plates and test the
meshing of the rack and pinion. (See above pictures of rack spacing). If satisfied fasten a “TEK”
screw directly through both the rack angle and the gate so that you have 5 “TEK” screws per
length of rack evenly spaced.

Installing the limit actuator
(Mandatory before programming)
1. Push the gate up against the closed stopper/keep.
2. Place magnetic actuator on top of the rack where it is half way across the reed switch. See below
3. Remove the rack screw (Holding the nylon teeth to the steel angle) closest to the middle of the slot in the actuator.
4. Replace this screw with the longer screw provided with the actuator.
5. Adjust the stopping position by sliding the actuator sideways. Check the closed limit LED while doing this.
After programming the run-time (page 15) the gate should stop a minimum of 10-20mm from the mechanical end stop. Adjust the
actuator if necessary.

Collision/obstruction/hindrance while opening. (All modes)
If a collision, obstruction or hindrance is encountered before the full open position is reached while opening, the gate will stop, back off and
wait for the next trigger input, before closing slowly. The status LED will flash rapidly once stationery after backing off of collision. Closing
trigger clears the status LED indication. For trigger responses see page mode selection on page 23.
Collision/obstruction/hindrance while closing. (All modes)
If a collision, obstruction or hindrance is encountered while closing, the gate will stop and reverse to the fully open position. The status LED
will flash rapidly once stationery after opening away from the collision. The next trigger input starts the gate closing slowly. Closing trigger
clears the status LED indication. For trigger responses see mode selection on page 24.
Multiple collision/obstruction lock-outs. (All modes)
On encountering 4 consecutive obstructions while closing the gate, the UMPETHA will not reverse back to the full open position. The response
will be a 5 sec beep tone, followed by a gentle momentary reverse away from the obstruction. The unit will now begin a mandatory 30sec
lockout whereby the only response to any trigger input will result in a tone so long as the trigger button is held. After 30sec a trigger input will
result in a repeat of the 5 sec beep and the gate opening 1 meter or to the full open position whichever is reached first. The unit will once
again lock out. This time the user must manual release the unit and test the travel by hand before attempting any further automation of the
gate.
The Status LED will flash rapidly throughout this procedure indicating a multiple obstruction lock-out has occurred.
Releasing the gearbox and re-engaging it will clear the LED status and the multiple obstruction lock-out routine.
Collision with closed stopper due to faulty or missing closed limit. (All modes)
If no limit input is made when expected (as calculated by the programmed run time) the UMPETHA will not reverse back to the open position
as it normally would when obstructed. It will however stop at the point of impact with the closed catch and emit a 5sec long beep tone. At
the next valid opening trigger the UMPETHA will re-emit the 5sec long beep tone and only open the gate by ±1 meter. This will allow for the
user to be able to enter the property and manually override the gate. The magnet actuator and limit can now be checked. If not
corrected and further attempts are made to operate the UMPETHA with a faulty closed limit condition the same routine will be repeated on
every operation.
If the user continues to attempt to operate the gate without manually releasing the gearbox while the gate is at the ±1meter position, the
result will only be a repeat of the 5sec beep tone.
Default: - 5KgF max resistance
