GENERAL SAFETY PRECAUTIONS

GB
This assembling manual is intended for professionally
competent personnel only.
The assembling, the electrical connections and the settings
must be completed in conformity with good workmanship and
with the laws in force. Read the instructions carefully before
beginning assembling the product. Incorrect assembling may
be a source of danger.
Packaging materials (plastics, polystyrene, etc) must not be al-
lowed to litter the environment and must be kept out of the reach
of children for whom they may be a source of danger.
Before beginning the assembling check that the product is in
perfect condition.
Before connecting to the mains check that the rating is
correct for the destination power requirements.
A multipolar isolation switch with minimum contact gaps of 3 mm
must be included in the mains supply. Check that upstream of
the electrical installation there is an adequate differential switch
and a suitable circuit breaker.
For repairs or replacements of products only original spare parts
must be used.
It is recommended that antistatic conductive earthed arm
bands be worn when manipulating electronic parts.
1. ASSEMBLING THE AUTOMATIC SYSTEM

1.1 Assembling procedure

- On the basis of the type of automatic system chosen,
use the sizing table (or the formulas shown) to obtain the
measurements required for the assembly of the automatic
system.
- Cut the aluminium of the transom box LT-10 mm and drill
a hole as shown in fig. 1.
1.3 Cut the aluminium of the protective casing LT-11 mm and
drill a hole as shown in fig. 1.
Note: clean the aluminium in order to remove any traces of cut
material, and clean the carriage sliding tracks in particular.
- Mark measurements A, B and C shown in the table (or
calculated using the formula) on the transom box with a
pencil.
- Insert 2 carriages for each leaf in the guide track; if
LM>1600 add another carriage per leaf (note 1).
- Make the carriages slide along the guide tracks in order to
check that the wheels are not dented (and replace them if
dented).
- Fasten the leaf connection brackets on the carriages (as
shown in the diagrams) and fasten the belt connection and
collision locking brackets to the carriages in the positions
shown in the table.
- Fit the component anchorage plates [10] in the appropriate
guide track of the transom box, see page 11.
- Secure the parts (without over-tightening): command and
drive unit [1], belt transmission [2], block [30] and batteries
[32], to the casing with the supplied screws, and follow the
measurements indicated in the table.
Note: with automatic systems LT≥3200 anchor the protective
casing support bracket [24].
- Position the rabbet stops [7] and rabbet plugs [6] inside
the guide track.

1.2 Adjusting the belt

- Loosen the screws that fasten the transmission unit to the
transom box.
KIT REX - IP1837
- Loosen the belt connection bracket.
- Cut the belt to measurement LB (see tables), thread the
belt LB between the motor pulley and the transmission unit
[2] and join it in correspondence with the belt connection
bracket (Note: cut off any excess length).
- Pull the entire transmission unit manually to the left and
anchor it to the transom box.
F
- Loosen the screw until the spring is compressed to 20÷22
mm.
- Lock in place with the screws [F].
- Insert the rabbet stop in the centre of the transom
box without tightening the screws. Keep the carriages
resting against the rabbet stop and fasten the belt on the
carriage.
Attention: a wrong adjustment can prevent the automation from
working properly.
- Tighten all the screws.
- Anchor the heads to the transom box.
2. WIRING
- Connect the command and drive unit [1] to the block [30]
and to the batteries [32] with the appropriate wires.
- For the 192C electronic board version only, connect the
1CELA photocell amplifier to the electronic board (fig. 2).
- Fasten the wires using the wire clips [9] supplied.
