USAGE FREQUENCY
The curve allows the calculation of the maximum working time (T) based on the utilisation factor (F).
To ensure proper operation it is necessary to be located inside the work area, shaded in grey.
The tests have been carried out at an ambient temperature of 22 °C; if the motor is at a higher ambient temperature or is
exposed to direct solar radiation, the utilisation factor may be reduced by up to 20%.

Note.
To ensure the full closing and opening of the gate, it is necessary to increase the manoeuvring times by 5 sec-
onds.
There are time slots throughout the day, where vehicle traffic is very high. Calculations should be made during that
time period.
Example.
What is the maximum working time for a gate that has a pause time of 20 seconds, and a time between full cycles
of 25 seconds?

CONCLUSION:
when we transfer the data obtained to the
graph 1, the maximum usage period for the model 240 is 2h
and 15 min and for model 360 it is 1h and 30 min.
Whenever the dimensions of the gate and the dimensions of
assembly allow, it is advisable to use model 240.
