INSTALLATION MANUAL
2) GENERAL INFORMATION
Electromechanical operator designed to automate residential-type gates.
The gearmotor keeps the gate locked on closing and on opening, without
needing an electric lock for leaves up to 3 m long. For leaves ranging between
3m and 5m long, the electric lock becomes indispensable.
The operator is provided with an electronic torque limiter. It must be controlled
by an electronic control panel provided with torque setting.
The end-of-stroke operation is controlled by two magnetic limit devices.
The operator is provided with an obstacle detection system complying with
EN12453 and EN 12445 standards.
The following optional accessories are available on request:
- Buer battery kit mod. BT BAT
Allows operation of the automation even when there is no mains power
supply for a short period of time.

6.1) How to read the installation distance tables
Select “a” and “b” according to the angle in degrees α° that the gate has to open.
The optimum “a” and “b” values for 92° opening at constant speed are highlighted.
If there is too large a dierence between “a” and “b”, the leaf will not travel
smoothly and the pushing or pulling force will uctuate during its stroke.
To respect the opening speed and ensure the controller operates correctly,
it is best to keep the dierence between “a” and “b” as low as possible.
The table has been worked out for A40 mm (KUSTOS BT A40), 20 mm (KU-
STOS BT A25) thick medium-size gate. Always check that there is no possible
collision between the gate and the operator.
7) FASTENING OF FITTINGS TO PILLAR Fig. C
8) POWER CABLE Fig. D
The board power supply cable must be of the H05RN-F type or equivalent.
The equivalent cable must guarantee:
- permanent outside use
- maximum temperature on the cable surface of +50° C
- minimum temperature of -25° C
If the motor vibrates but does not rotate, the problem may be:
- Incorrect wiring (see wiring diagram)
- If the leaf moves in the wrong direction, swap over the motor’s start con-
nections in the control unit.
The rst command following a mains power outage should be open STOP
LEAVES.
9) ATTACHING MOTOR TO FASTENING ON PILLAR Fig. E
10) MAXIMUM TILT Fig. F
11) CORRECT INSTALLATION Fig. G
Correct installation entails maintaining a rod stroke margin of approx. 5-10
mm to avoid possible trouble with operation.
12) FASTENING OF FITTINGS TO LEAF Fig. H
Line up the front and rear brackets as shown in Fig. H Ref. 1.
13) OPERATOR ATTACHMENT ON DOOR Fig. I
14) LIMIT DEVICE ADJUSTMENT Fig. J
ATTENTION! To avoid braking the limit switch cable, tighten screw A keeping
the wire B well tightened (as shown in Fig. J Rif. 3).
15) DIMENSIONS Fig. L
16) TIPS FOR SPECIAL INSTALLATIONS Fig. M, N, O.
With the leaf fully open, create a recess to accommodate the operator.
Fig. M gives the minimum dimensions of the recess for the various KUSTOS
BT A25 - KUSTOS BT A40 models.
If distance “b” is greater than the values given in the installation tables:
- create a recess in the pillar Fig. N
- move the leaf so that it is ush with the pillar Fig. O.
17) LEAF STOPS AT GROUND LEVEL
For the actuator to work properly, it is advisable to use stops “Fig. P Rif. 1” to
stop the leaves both when they are open and closed, as illustrated in Fig. P.
The leaf stops must prevent the actuator rod from reaching the end of its travel.
18) MANUAL OPENING (See USER GUIDE -FIG.Y-).
19) ELECTRIC LOCK
WARNING: In the case of leaves longer than 3m, it is indispensable
to install a solenoid latch.
For electric lock connection, the optional board is required (refer to the
appropriate instruction).
