2) GENERAL OUTLINE
Compact electromechanical barrier suitable for limiting private areas, parkings,
access areas for vehicles only. Available for passageways from 4 to 8 metres.
Adjustable electronic limit switches, they guarantee correct boom stopping
position. The emergency release device for manual manoeuvre is controlled
by a key lock.
The actuator is always supplied for left-hand side fitting. However, when nec-
essary, the opening direction can be reversed by means of simple operations.
The BM mod. foundation base (on request) makes barrier installation easier.
Appropriate fittings make it easy to install accessories.
The MERAK BM6-MERAK BM8 control panel is supplied by the manufacturer
with standard setting. Any change must be set by means of the incorporated
display or by means of the universal programmer.
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 maintenance
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.
TESTING
The MERAK BM6-MERAK BM8 panel controls (checks) the start relays and
safety devices (photocells) before performing each opening and closing cycle.
If there is a malfunction, make sure that the connected devices are working
properly and check the wiring.

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 warning
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.

- Carry out bar balancing as described in Fig. G3.
- 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 barri-
ers. Otherwise, the limit devices will not operate or an encoder direction
error will be displayed.

10) ELECTRICAL INSTALLATION SET-UP
WARNING: before opening the door, the spring must be unloaded (ver-
tical 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.).
Warning! For connection to the mains, use a multipolar cable having
minimum 3x1.5mm
cross section and complying with the previously
2
mentioned regulations (for example, if the cable is not protected, it must
be at least equal to H07 RN-F, whereas if it is protected it must be at least
equal to H07 VV-F with a 3x1.5 sq mm
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 differential switch with
a 0.03A threshold just before the automation system.
QR)
Control panel and incorporated receiver.
S)
Key selector.
AL)

M)

F)

CS)

CF)

T)

RMM) Inductive metal mass detector.
LOOP) Mass detector loops.
11) CONNECTION (FIg. G-I)
WARNING: The electrical connections must be carried out workmanlike by
cross section).
