BEFORE YOU BEGIN

Planning and precision are vital for the
mounting of an underground opener, in order to
ensure that unforeseen circumstances do not
limit or prevent proper operation later.
Adequate drainage facilities are essential to avoid
malfunction.
Size of gate: The size of the gate is one very important
factor.
Wind can slow the gate down or distort it, causing a marked
increase in the force required to move it.
Weight of gate: The specified weight of the gate only gives
a rough indication of the output required from the drive. The
function which the gate is expected to perform is also
important in this connection.
Temperature: Low outdoor temperatures can make it more
difficult or impossible to set the gate into motion (e.g.
because of soil changes).
High outdoor temperatures may cause the temperature cut-
off (at about 135°C) to be triggered earlier.
Operating frequency/duty factor: The drives have a
maximum duty factor of around 30-50% (e.g. 50% of one
hour). This factor depends heavily on many influencing
factors. The drive is not suitable for systems with a high
cycling rate (continuous operation) and such use would
mean that the guarantee becomes invalid.

PREPARATIONS
Before installation, please check contents of packaging.
Please remember that you will require some additional
material not included in the assembly kit delivered, such as
empty piping, cables, screws, plugs, etc. In order to avoid
undesirable oscillation, the wing should be stable and the
hinges should have as little play as possible. The more easily
the gate moves, the finer should the force adjustment be
made. Low-rigidity wooden gates should be reinforced with a
metal frame.

INSTALLATION OF THE UNIT

1. The pivot point of the gate can be found on the mounting
box = pivotal point of the arm (SUB 110 and SUB 180)
(figure 5-8).
SUB 110 opens gates up to 110º. Mount the arm which
will later be welded to the gate and don't forget the
bearing ball. For details see also under assembly and
adjustment (figure 2-4).
SUB 180 opens gates by up to 180°. A detailed
description of the assembly is included with the SUB 180
arm.
SUB 100S is a special arm with rails with which the drive
does not have to be positioned directly beneath the pivot
point. This is ideal for retrofitting or for special pillar
situations (max. 300 kg/3m). A detailed description of the
assembly is included with the SUB 100S arm. Available
mid 2005.
2. Check the overall dimensions to ensure that you will have
enough room to dig out a hole for the motor housing. The
opening angle of the gate has an important influence on
the position of the motor housing (figures 5-7).
The motor housing must be set in concrete. The piping for
the electrical wiring and the drainage should be borne in
mind in this connection (figure 1). Remember that the final
dimensions of the installation (including plaster layer etc.)
determine the room available. The top of the motor
housing should be slightly higher than the concrete
surrounding it.
The concrete takes a couple of days to set completely.
You should aim at a strength rating of at least MG2a
according to DIN standards (normal strength).
3. Once the motor housing has been set in place, the gate
can be mounted on top of it. Additional hinges will certainly
be needed to ensure proper guidance.
4. The arm with the facilities for switching to manual
operation must be welded on to the gate. Turning the
special key in the hole provided for it switches the system
to manual operation so that the gate can be opened by
hand if necessary (figures 1, 4 and 8).
5. Stops must be mounted on the floor to limit the limit the
motion of the gate (figure 9).
6. After all assembly work has been completed, it is advisable
to protect the motor housing against seepage of water with
the aid of a layer of silicone sealant.
Tip:
If the gate is delivered at the same time as the drive (no
retrofitting), you should proceed as follows:
The box should be welded onto the gate pillar first before
installation. This ensures that the pivot points and spacings
cannot become displaced. The box is assembled with the
pillar.
Caution: During installation there is a risk fo becoming
trapped between the driven component and the surrounding
parts of the building (e.g. a wall) due to the opening
movement of the driven component.
