3.2.1 - Calculation of maximum number of cycles per day for
devices PH100W and FL100W
The PH100W and FL100W devices include a solar cell, the energy pro-
duced by which is collected by a rechargeable battery; for this reason,
they must be installed outdoors, where the cell can receive direct sunlight
for most of the day.
With a simple calculation, it is possible to estimate the maximum number
of cycles per day, in a given period of the year, which the automation is
capable of completing. This is to ensure that the energy produced from
the cell and stored in the battery, remains higher than that consumed by
the manoeuvres of the gate.
The calculation starts with establishing the “coefficient base” in relation to
orientation of the device or direction in which the solar cell is facing; and
on the basis of the world hemisphere in which the installation is located.
01.
Choose the coefficient base in
Table 1
.
The available solar energy (bad weather days must also be included in this
value) is linked to the geographical position of the location and will vary
throughout the year.
02. In fig. 6 , locate the earth parallel in relation to the geographical posi-
tion.
03. In table 2 choose the multiplier, based on the desired period of the
year (or use the minimum value or the average value) and the earth
parallel (geographical location of the place).

Northern hemisphere Southern hemisphere Coefficient base (*)

(*) The coefficient base is valid for outdoor installations without the presence of certain structures (such as trees or buildings) that can create shadows; otherwise the
value will be reduced by 1/3 or half depending on the level of shadowing caused.
