USAGE FREQUENCY
The curve allows us to calculate the maximum working time (T) as a function of the frequency of use (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 frequency may be reduced by up to 20%.

: time between complete manoeuvres
(opening-closing)
Graph.1
Note. To ensure the full closing and opening of the gate, it is necessary to increase the manoeuvring times by 5
seconds.
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 30 seconds?
