5.4 Manual release
Unlock wire rope with lever
1. put on the rope the clamp and the return spring
(fig. 7-B-C), then pass the thread through the tensioner and
the sheath provided (fig. 8-A);
2. preload the spring and tighten the clamp (fig.8-B).
3. for passage of the lever release system see the manual
RELEASE MECHANISM FOR MOTORS 550MS. (fig. 12)
6. SWITCH ADJUSTMENT
Motor left (seen from inside the room)
Opening: release the actuator (see par. "Manual release") and move
the leaf to the required open position. Turn the opening cam clock-
wise until the micro-switch trips and secure it with the central screw
(fig. 19-A , 19-B).
Closing: move the leaf to the required closed position. Turn the clos-
ing cam anticlockwise until the micro-switch trips and secure it with
the central screw (fig. 19-A , 19-B).
Motor right (seen from inside the room)
Opening: release the actuator (see par. "Manual release") and move
the leaf to the required open position. Turn the opening cam anti-
clockwise until the micro-switch trips and secure it with the central
screw (fig. 20-A , 20-B).
Closing: move the leaf to the required open position. Turn the clos-
ing cam clockwise until the micro-switch trips and secure it with the
central screw (fig. 20-A , 20-B).
Whenever the position of the microswitch stops is
modified, it is advisable to repeat the saving proce-
dure on the control board (see D760M instructions).

BIUNO - 230V AC
POS. COLOR
1 Orange
2 Blue
3 Red
4 Yellow / Green
5 e 6
Use control units with torque limiting device only.
BIUNO-BT - BIUNO-BTR - 18/24V DC
POS. COLOR
1 Red
2 Black
3 White
4 Brown
5 Blue
Use only control units with electric clutch.
The distance between the control unit and the motor must not exceed
10 – 12 m.
TAU srl recommends its composite cable, Code M-03000010CO;
Place the control unit (external versions) in the im-
mediate vicinity of the motors.
Be careful not to run cables for auxiliary devices
inside raceways housing other cables supply-
ing power to large loads or lights with electronic
starters.
In the event control pushbuttons or indicator lights
are installed inside homes or offices several metres
away from the actual control unit, it is advisable to
decouple the signal by means of a relay in order to
avoid induced interference.
CAUTION-If during the memorization process one
or both of the doors close instead of opening, stop
the automations and reverse the polarity of the mo-
tor.

8. USE
The BIUNO automation has been designed for to move articulated doors
with leaf lenght max. 1,2 m and leaf weight max. 120 Kg (BIUNO) or 135
Kg (BIUNO-BT/BTR); and hinged doors of max. of 2 m and weight max.
of 300 kg.
It is categorically forbidden to use the equipment
for any other use or under circ umstances different
from those mentioned herein.
The electronic unit (that must have the built-in electric clutch) normally
makes it possible for you to choose from:
automatic: a command pulse will open and shut the door
semiautomatic: a command pulse will open or shut the door
If there is a blackout the gear-motor will work for the models in the
BIUNO-BT/BTR series powered by a buffer battery; to control it manually
first operate the unlock mechanism.
Furthermore, it also comprises electrical equipment and therefore must
be approached and used with caution and foresight. In particular we re-
commend:
• not to touch the equipment with wet hands and/or bare or wet feet;
• not to perform the automatic or semiautomatic function in the pres-
ence of known or suspected malfunctions;
• not to pull the cable to disconnect the equipment;
• not to let children, or those unable, use the cabinet keys or controls
(including remote controls) even if only to play with;
• do not touch the motor unless you are certain it is cold;
• only operate the door when it is completely visible;
• not to enter within the operating range while it is moving, wait for
it to stop;
• not to let children or animal play within the operating range of the
door;
• to perform periodic maintenance by specialised personnel;
• if there is a fault, turn off the power supply. Use the manual man-
oeuvre only if safe. Do not attempt to resolve the problem yourself,
contact a qualified technician of the manufacturer or authorised by
the manufacturer. In any case, make sure that the spare parts are
original so that the safety of the automation is not compromised.
9. MAINTENANCE
The actuators in the BIUNO serie need very little maintenance. However,
to ensure they always work properly, the door has to be in good condition:
hence we shall describe briefly what you need to do to keep your
articuilated door efficient.
ATTENTION: no one, except the person who services the equipment
(who must be a specialised technician), should be able to command the
automatism during servicing. Consequently, it is advisable to turn the
electricity off at the mains also to avoid possible electric shocks. If
the electricity has to be on for certain checks, check or disable all
command devices (remote controls, push button panels, etc.) except for
the device being used by the maintenance person.
Routine maintenance
Each of the following operations must be carried out when the need
arises and, in all cases, every 6 months (always 750 work cycles).
Articuled door
• Lubricate the hinges and telescopic arms.
Automation system
• check the safety devices (photocells, etc.). They must work
properly in dangerous situations and cut in
during installation;
• check that the slide way is clean and free from debris;
• push the door fully open making sure never to use a force of
more than 150 N (15 kg);
• make sure the door moves smoothly;
•check that the screw connections are perfectly tight.
FREQUENCY: every 750 manoeuvres or 6 months, failing which
the guarantee lapses.
Extraordinary maintenance or breaks
• If there are any complex jobs that need doing on electromech-
