9.2.3 - Calculation of maximum number of cycles per day
This product is expressly designed to also be able to operate with the
power supply system of the PF solar energy model. Suitable technologies
have been supplied to minimise the power consumption when the auto-
mation is stopped, by turning off all the devices that are not essential to
the operation (for example the photocells or the key selector light). In this
way all the available energy is stored in the battery, and will be used for the
movement of the gate.
Caution! - When the automation mechanism is powered by PF, it
cannot and IT MUST NOT BE POWERED by the electricity grid at
the same time.
Usage limits: maximum number of cycles per day, in a given period of
the year.
The PF solar-powered system allows full energy independence for the
automation, whilst the energy produced by the solar energy panel and
stored in the battery remains higher than that consumed by the gate
manoeuvres. With a simple calculation is possible to estimate the maxi-
mum number of cycles per day that the automation can execute in a given
period of the year in order that this energy balance remains positive.
The first part of the available energy calculation, is explained in the PF
instruction manual; the second part of calculation of energy consumed
and therefore, the maximum number of cycles per day, is explained in this
chapter.
Establish the available energy
To determine the available energy (see also the PF instruction manual)
proceed as follows:
01. In the ground map supplied in the PF kit instruction manual, locate
the system installation point; then obtain the value of Ea and the
degrees of latitude of the location (Ex. Ea = 14 and degrees = 45°N)
02. In the graphs (North or South) shown in the PF kit instruction manual,
locate the curve which relates to the degrees of latitude of the posi-
tion (ex. 45°N)

03. Choose the period of the year for which you wish to do the calcula-
tion, or choose the lowest point of the curve if you wish to carry
out the calculation for the harshest period of the year; then find the
corresponding Am value (i.e., December, January: Am= 200)
04. Calculate the available energy value Ed (produced by the panel) by
multiplying: Ea x Am = Ed (i.e. Ea = 14; Am = 200 thus Ed = 2800)
Establish the energy consumed
To calculate the energy consumed by the automation proceed as follows:
05. In the table below choose the box corresponding to the intersection of
the row with the weight and the column with the opening angle of
the gate. The box contains the severity index (K) of each manoeuvre
(i.e. WU200S with 130 Kg leaf and opening of 95°; K = 125).
Opening angle
Leaf weight 90°
<= 100 kg 56
100-200 kg 68
200-300 kg 81
300-400 kg 95
06. In table A below, select the box corresponding to the intersection of
the row with the value of Ed and the column with the value of K. The
box contains the maximum possible number of cycles per day (e.g.
Ed= 2800 and K= 125; daily cycles ≈ 20)
If the number obtained is too low for the intended use, or falls within the
"not recommended usage area", you can evaluate the use of 2 or more
solar power panels or a solar power panel of greater power. Contact the
Nice Support Service for further information.
The method described, allows you to calculate the maximum possible
number of cycles per day that the automation is capable of carrying out,
according to the solar energy supplied. The calculated value should be
considered as the average value and equal for all the days of the week.
