INSTALLATION MANUAL
2) GENERAL OUTLINE
Compact electromechanical barrier suitable for limiting private areas,
parkings, access areas for vehicles only. Available for passageways from 3
to 6 metres. Adjustable electronic limit switches, they guarantee correct
boom stopping position.
The emergency release device for manual manoeuvre is controlled by
a personalised key lock.
The actuator is always supplied for left-hand side fitting. However, when
necessary, the opening direction can be reversed by means of simple
operations.
The CBO mod. foundation base (on request) makes barrier installation
easier.Appropriate fittings make it easy to install accessories.
The
MERAK BG - MERAK BG S
control panel is supplied by the manufac-
turer with standard setting. Any change must be set by means of the
incorporated display or by means of the universal programmer.
Fully supports EELINK and U-LINK protocols.
Its main features are:
- Control of 1 low-voltage motor
- Obstacle detection
- Separate inputs for safety devices
- Configurable command inputs
- Built-in radio receiver rolling code with transmitter cloning.
The board has a terminal strip of the removable kind to make mainte-
nance or replacement easier. It comes with a series of prewired jumpers
to make the installer’s job on site easier. The jumpers concern terminals:
70-71, 70-72, 70-74. If the above-mentioned terminals are being used,
remove the relevant jumpers.

5) FITTING OF THE ACTUATOR
WARNING! The barrier must be exclusively used for vehicles to
drive through. Pedestrians must not walk within the operator
manoeuvring area.
An appropriate pedestrian passageway must be
provided for.
The passageway must be suitably indicated by means of the warn-
ing signs illustrated in Fig.A.
WARNING: before opening the door, the spring must be unloaded
(vertical boom).
The door of the box must be facing towards the inside
of the property. When you stand in the middle of the passageway, facing
outwards, if the box is on your left, the barrier is left-hand fitted, if the
box is on your right, the barrier is right-hand fitted.
The actuator is always supplied for left-hand side fitting.
6) Right-hand fitting (Fig. A, B, C, D).
7) Left-hand fitting (Fig. AA)
- Carry out bar balancing.
- Set the Direction Reversal logic to ON in the control panel.
Warning: the Direction Reversal logic must be configured to
OFF for left-hand fitted barriers, and to ON for right-hand fitted
barriers. Otherwise, the limit devices will not operate or an encoder
direction error will be displayed.

12) ELECTRICAL INSTALLATION SET-UP
WARNING: before opening the door, the spring must be unloaded
(vertical boom).
Set up the electrical installation (fig. A) with reference to
the current regulations for electrical installations. Keep the mains power
supply con-nections definitely separate from the service connections
(photocells, electric edges, control devices etc.).
Fig. A shows the number of connections and section for a 100m length
of power supply cables; for greater lengths, calculate the section for the
true automation load. When the auxiliary connections exceed 50 metre
lengths or go through critical disturbance areas, it is recommended to
decouple the control and safety devices by means of suitable relays.
The main automation components are (fig. A):
I)
Type-approved adequately rated omnipolar circuit-breaker with
at least 3,5 mm contact opening, provided with protection against
overloads and short circuits, suitable for cutting out automation from
the mains. Place, if not al ready installed, a type-approved differ-
ential switch with a 0.03A threshold just before the automation
system.
QR)
Control panel and incorporated receiver.
S)
Key selector.
AL)
Blinker
M)

F)

CS)

Ft,Fr)

CF)

T)

WARNINGS -
When performing wiring and installation, refer to the stan-
dards in force and, whatever the case, apply good practice principles.
Wires carrying different voltages must be kept physically separate from
each other, or they must be suitably insulated with at least 1mm of ad-
ditional insulation.
Wires must be secured with additional fastening near the terminals,
using devices such as cable clamps. All connecting cables must be kept
far enough away from dissipaters.
13) CONNECTION (Fig. G)
Once suitable electric cables have been run through the raceways and
the automated device’s various components have been fastened at the
predetermined points, the next step is to connect them as directed and
illustrated in the diagrams contained in the relevant instruction manuals.
Connect the live, neutral and earth wire (compulsory). The mains cable
must be clamped in the relevant cable gland, and the accessories’ wires
in the cable gland, while the earth wire with the yellow/green-coloured
sheath must be connected in the relevant terminal.
