. MAXIMUM USE CURVE

The  curve  makes  it  possible  to 

establish maximum work time (T) 

according to use frequency (F).

With reference to IEC 34-1 Stan-

dard, the 740-741 gearmotor with 

an S3 duty, can operate at a use 

frequency of 30-40%.

To ensure efficient operation, it is 

necessary to operate in the work 

range below the curve.

Important:

 The curve is obtained 

at  a  temperature  of  20°C. 

Exposure to the direct sun rays 

can  reduce  use  frequency 

down to 20%.

Calculation of use frequency

Use frequency is the percentage 

of effective work time (o closing) compared to total time 

of cycle (o c pause times).

Calculation formula:

 

 

 

 

Ta + Tc

 

 

% F = 

  X 100

 

 

 

      Ta + Tc + Tp + Ti

where:   

Ta = opening time

Tc = closing time

Tp = pause time

Ti = time of interval between two complete cycles

4. ELECTRICAL SET-UP (standard system)

5. INSTALLING THE AUTOMATED SYSTEM

5.. Preliminary checks

To  ensure  safety  and  efficiency  of  the  automated  system,  make 

sure the following requirements are observed before installing the 

system:

• The gate structure must be suitable for automation. The following 

are necessary in particular: wheel diameter must be in proportion 

to the weight of the gate, an upper track must be provided, plus 

mechanical travel stops to prevent the gate derailing.

•  The  soil  must  guarantee  a  perfect  stability  of  the  foundation 

plinth.

• There must be no pipes or electric cables in the plinth excavation 

area.

• If the gearmotor is located in the vehicle transit or manoeuvre 

area, adequate means of protection should be provided against 

accidental impact.

• Check if an efficient ear-

thing  is  available  for  con-

nection to the gearmotor.

5.2. Masonry for foun-

dation plate

1- Assemble the foundation 

plate  as  shown  in  figure 

04.

2- In order to ensure that the 

pinion  and  rack  engage 

correctly, the foundation plate must be positioned as shown in 

Fig. 05 (right closing) or Fig. 06 (left closing).

Warning: The arrow on the foundation plate must always point to 

the gate, see Figs. 05-06.

3- After determining the position of the foundation plate, make a 

plinth as shown in Fig. 07 and wall the plate, providing several 

sheaths for routing the cables. Using a spirit level, check if the 

plate is perfectly level. Wait for the cement to set.

4- Lay the electric cables for connection to the accessories and 

power supply as shown in diagram of Fig. 03. To facilitate con-

nections to the control unit, allow the cables to protrude by at 

least 50 cm from the hole on the 

foundation plate.

5.. Mechanical installation

1- Remove the cover, Fig. 08 ref. 1.

2- Position the operator on the foun-

dation  plate,  using  the  supplied 

washers and nuts as shown in Fig. 

09. During this operation, route the 

cables  through  the  appropriate 

openings in the motor body (See 

Fig.01 ref.9). If necessary, the two 

holes can be joined using a ham-

mer to obtain a wider space.

3- Adjust the height of the gearmotor 

and the distance from the gate, referring to dimensions in Fig. 

10.

 Attention:  This  operation  is 

necessary  to  ensure  the  rack 

is  correctly  secured  and  to 

enable any new adjustments.

4-  Secure  the  gearmotor  to  the 

plate, tightening the nuts.

5- Prepare the operator for ma-

nual operation as described in 

paragraph 8.
