2,20 METERS AND 250 kg PER LEAF - 24V

Thank you for choosing a SERAI ELETTRONICA product, which we are confident will perform to your requirements.

Please be advised that you are about to fit a system classified as “a power-operated drive designed to move automatic

gates and doors in commercial or residential buildings accessed by vehicles and persons”, and as such, the system

must be considered potentially hazardous. By law, you are responsible for rendering this equipment as “safe” as is re-

asonably possible.

Installation and maintenance of equipment of this kind must therefore be carried out by skilled, qualified and trained

personnel, working in a professional manner, as provided for by law n. 46/90 and any subsequent amendments and

supplements. The law in question prohibits the construction of these types of systems by non-qualified

personnel.

SERAI manufacturing complies with the following legislation:

Applicable directives for the CE marking :

Machines: 98/37/EEC

Low Voltage: 73/23/EEC

Electromagnetic Compatibility: 89/336/EEC

General applicable standards:

Electrical Safety: IEC EN60335-1 + IEC EN60335-2-103

Electromagnetic Compatibility - Emissions: CEI EN61000-6-3

Electromagnetic Compatibility - Immunity: CEI EN61000-6-1

Apart from the legislation mentioned above, you are also reminded to comply with the following standards during the

installation phase.

General applicable standards:

Safety of electrical systems in non-specialised environments: CEI 64-8

Specific product standards applicable:

Safety in the use of power-operated doors - requirements: UNI EN12453

Safety in the use of power-operated doors - testing methods: UNI EN12445

SERAI products enable users to build systems which comply with these standards. This is extremely

important as THE INSTALLER IS LIABLE FOR THE SYSTEM AND FOR ENSURING ITS OPERATION

COMPLIES WITH LEGAL PROVISIONS.

This handbook must be read in full before proceeding with the installation of the various parts of the system.

The installation of the mechanical end stops for gate opening and closure is necessary for system safety pur-

poses and therefore this operation must be performed before proceeding with the installation of the control

unit.

1- Install the gate stop blocks, choose the motor position and the opening angle refering to the following shares

see picture 5 :

- Share A: MAX 100mm. The motor could be installed near the pillar if there is a movable hinge, to allow the

motor insertion

- Share B: 30 ÷ 40 mm. In any case keep the parallelism among telescopic arm and the gate-wing.

- Share C: 330 ÷ 340 mm

- The installation of the mechanical end stops for gate opening and closing is necessary for

system safety purposes.

For a correct working and in order to avoid the shearing strictly respect the above mentioned

shares with a tolerance of +10 mm.

1.A- In the event that the suggested shares cannot be respected, or for openings exceeding 90°, you have to use

the long telescopic arm SR93.97 in accordance with the new shares:

- Share A: MAX 150mm

- Share B: MAX 100 mm

- Share C: 430 ÷ 440 mm

ATTENTION:

Using thelong telescopicarm, shearing-dangerconditions mayhappen.

3- Prepare the piping and open the cable entries

on the foundation box for the electric

connections. See Fig. 6

4- Insert the spacing plastic tube on the

Foundation box. See Fig. 7

CAUTION:

ensure that the spacing tube is

centred both in horizontal and

vertical position with reference

to the foundation box.

5- Insert the spacing sheet on the Foundation

box. See Fig. 8

Prepare the excavation for the housing of the

foundation box. Remove the motor from the

foundation box, place the foundation box

ground level and verify the horizonal level and

the vertical alignment of the pivots. See Fig.

6- Seal up with adhesive tape. See Fig. 9

7-Cement definitively with concrete. See Fig. 10

ATTENTION:

During the cementing phase the

foundation box may rise up. Keep the

foundation box anchored. See fig 11

8- Before inserting the motoreducer take off the

spacing sheet and the plastic tube. See Fig. 12

Fig 13

9- To make easy the eventual removal of the motor

and avoid any damage of the foundation box, insert

the 4 galvanized plates (which are supplied) in the

4 ends-inside the special circular places. See

picture no. 13.

10- Insert the motor, the telescopic arm and fix the

bracket on the gate. See Fig. 13.

IMPORTANT: lubricate the telescopic arm with

grease.

ATTENTION:

- Leave at least 35 cm of feeder under the

motor, for taking out the motor in case of

maintanance. Fig. 13

- The connection between the power supply

cable of the motor and the cable of the

control panel has to be carried out outside

the foundation box and inside a weather

proof housing. On the contrary a water

infiltration may be occur through the

power supply cable causing the motor

failure. See Fig. 13

11- Give power supply to the motor.
