DACE is a proven leader in the manufacturing of automac gate & garage operators and strives to manufacture
high quality products using the latest technology. We are constantly working on upgrading our products to bring
you, our clients, products of the nest quality.
We strongly recommended using the services of an experienced gate installer to install your gate opera-
tor but if you intend installing the operator yourself, the manual must be read carefully before any
installaon begins.
While we have taken all reasonable steps to ensure that your gate operator is safe to install and use, it must be
noted that your gate is a heavy moving piece of equipment and can cause serious damage or injury if it strikes an
object or person. Your gate operator has built in electronic collision sensing which will make the gate stop and
reopen if it strikes an object. This does mean however, that the gate will actually strike the object before it stops.
It is because of this that we strongly recommended that DuraOpcs Safety Beams are installed to reduce the risk
of the gate striking an object.
The installaon of beams does not guarantee that the moving gate will not strike an object in it’s path.
Check the following items before installing the operator:
 That the rail is level – the gate must not move on its own at any stage (discuss opons available to you with
your supplier if the rail is not level).
 That the wheels are turning freely and are not jammed.
 That the gate is not bent or bowed in any way.
 That the rail has sucient end stops so that the gate can never run o the end of the rail.
 That the portal is constructed in such a way that the gate can not fall over.
 That the top rollers are turning freely and are not jammed.
 That the an li device is sucient in order to stop the gate from being lied o the rail.
 That the gate mass or start-up force does not exceed the maximum as stated in the specicaons.
 That the gate does not jam in the catch bracket when closing or opening.
 The gate must not exceed the maximum number of operaons stated in the specicaons.
 Extreme care should be taken when automang a gate that is fully cladded, as wind resistance can cause the
gate to not close properly.
Only when all the above points are sasfactory should you go ahead with installing the gate operator. If a gate
causes damage or injury the installer of the equipment may be held liable.
DO NOT CONNECT MAINS VOLTAGE DIRECTLY TO THE CONTROLLER
If you intend to run AC directly from the building mains supply to the transformer, the wiring should be
done by a qualied/registered electrician. This is a legal requirement and failure to do so may lead to
non-compliance of property or law suits against the property owner in the event of an accident.
 When running mains supply to the gate, it is recommended that you contact your local E.C.A. (Electrical
Contractors Associaon) in order to obtain the legal wiring regulaons relevant to the region in which you
live.
 Electrical shock can occur while installing this equipment
 Injury or death by electrocuon may lead to law suits against the installer/homeowner.
 All wiring must be run in conduit. The supply wires must be run separate to any other wiring.
 Underground mains supply must be run in armoured cable.
 Under no circumstances may Communicaon cable, Ripcord or Cabtyre be used for 220V/240V mains
connecons.
 Ensure that all electrical power is switched o before any electrical connecons are made.
 Do not open, tamper or modify any of the electronic components of this equipment in any way.
 Do not aempt to repair the equipment, this should only be done by a qualied DACE technician.
 DACE will not be held liable for any accident / incident resulng in damage, injury or death ensuing from the
incorrect installaon of the automac gate operator.
 Although these operators have built-in collision sensing, substanal damage can sll occur. For this reason
DuraOpcs Safety Beams should be used on all installaons.
 For safety reasons, the Ulma RT 25/50 will only close at the maximum speed of 50 meters per minute if
there are safety beams connected to the operator.
 Do not allow children to play near or with any gate, gate operator or remote control.
 It is the responsibility of the installer to ensure that the gate is in good working condion before automang
the gate. Connues……...
INTRODUCTION & RECOMMENDATIONS

 DACE cannot be held responsible for a gate bumping either of the ends stops if it runs on a slope.
 Do not operate the gate unless within direct sight of the gate.
 A gate is a heavy piece of equipment and injury, even death, may occur due to incorrect installaon or opera-
on of the equipment. There are a number of areas that may cause entrapment which could lead to injury.

The gate Pull and Running Forces must be
measured before installing the operator. Should
the measured forces exceed those in the table
below, then the operator must not be installed.
It may be possible to reduce these forces by
carrying out maintenance on the gate & rail but
if not, then the operator must not be installed.
These forces can be measured using a shing or
luggage scale (see gure alongside)
Pull Force: place the gate in the fully open/closed posion and pull on the scale unl the gate starts moving. The
value showing on the scale at the point that the gate starts moving is the Pull Force kgf.
Running Force: this is the maximum value read while the gate is moving before coming to the fully open posion.

We do not recommend automang a gate which is not level. Failure to level the gate will put undue
stress on the operator. Furthermore, if the operator is in manual override mode, the gate may run freely
down the slope and present a safety risk.
The gate should always be level. This can be achieved by leveling the track using supports or spacers.
GATES ON A GRADIENT
In circumstances where it is not possible to level the gate, it is necessary to check that the pull and running
forces do not exceed the maximum values as per the table on page 8.

I. Lay a concrete slab 400mm x 400mm x 200mm:
• Dig a hole and place the conduit ❶ in the correct
posion.
• Fill the hole with concrete & allow to set.
II. Place the foundaon plate on the concrete slab &
feed the conduit through the cable inlets ❷.
III. Ensure a 23mm clearance between the inner
edge of the foundaon plate and the edge of the
gate. This measurement is based on DACE rack.
See below to calculate clearance if using other
rack.
IV. Aach the foundaon plate to the slab using four
8mm anchors ❸.
ANCHORING THE FOUNDATION PLATE
Open the ‘manual release door’ and pull the
release pin unl the lid is free. The Lid can now
be removed.
REMOVING THE LID
1.Open the ‘manual release door’ and rotate the thumb
wheel clockwise, just unl the gate begins to move.
2.The thumb wheel must not be allowed to rotate too far.
3.To re-engage the gearbox, rotate the thumb wheel
counter clockwise while pushing on the gate unl you
hear a click in the gearbox.
4.Do not rotate the thumb wheel any further aer hearing
the gearbox click.
PLACING THE OPERATOR IN MANUAL OVERRIDE
To calculate the clearance required between the edge of the
foundaon plate and the edge of the gate (A), measure the
width of the rack (B) and minus 9.
eg. If the width of the rack is 32mm less 9 = 23. Thus the
clearance required is 23mm

1.Raise the adjusng nuts ~ 5mm before mounng the
operator to allow for ne height adjustment at a later
me.
2.Mount the operator on the foundaon plate.
3.Place a Spirit Level on top of the operator base while
fastening the three securing nuts and washers ensuring
that the operator is level.
4.Manually move the gate fully open and closed very
slowly to ensure that the gate does not collide with
the operator in any way.
5.Be sure to remove any cement/debris around the pinion
gear.
Mount the operator above the ood level or, if this is
not possible, build a small protecve wall structure
in front of the operator to divert the water ow.
