10.2.3 - Maximum possible number of cycles per day
This product is specifi cally designed to operate also with the PF solar
power supply system. Special technical provisions have been envisaged
to minimise energy consumption when the automation is stationary, by
turning off all devices not essential to operation (for example photocells
and the key-operated selector switch). In this way all energy available and
stored in the battery is used to move the gate.
Caution! - When the automation is powered by the solar power system
"PF", IT MUST NEVER BE POWERED at the same time by the mains.
Application limits: maximum possible number of cycles per day within
a set period of the year.
The PF solar power system enables complete power autonomy of the
automation, until the energy produced by the photovoltaic panel and
stored in the battery remains above the amount consumed during gate
manoeuvres. A simple calculation enables an estimate of the maximum
number of cycles per day performed by the automation in a certain period
of the year, provided that a positive energy balance is maintained.
The fi rst step in calculating the energy available, is dealt with in the
PF instruction manual; the second step in calculating the energy con-
sumed and therefore the maximum number of cycles per day, is dealt
with in this chapter.
Calculating the energy available
To calculate the energy available (refer also to the PF instruction manual)
proceed as follows:
01. On the terrestrial map supplied in the PF kit instruction manual,
locate the point of system installation; then read the value Ea and the
degrees of latitude of this location (E.g. Ea = 14 and degrees = 45°N)

command, it restores normal operation (with a short delay). This function
is used to reduce consumption; an important factor when the unit is pow-
ered by photovoltaic panels.

02. On the graphs (North or South) supplied in the PF kit instruction man-
ual, locate the curve for the location's latitude (e.g. 45°N)
03. Choose the period of the year on which to base the calculation, or
select the lowest point of the curve to calculate the worst period
of the year; then read the corresponding value Am (e.g. December,
January: Am= 200)
04. Calculate the value of energy available Ed (produced by the panel) mul-
tiplying Ea x Am = Ed (e.g. Ea = 14; Am = 200 therefore Ed = 2800)
Calculating the energy consumed
To calculate the energy consumed by the automation, proceed as follows:
05. On the table below, select the box corresponding to the intersection
between the line with the weight and the column with the opening
angle of the gate leaf. The box contains the value of the severity
index (K) for each manoeuvre (e.g. WG2S with a leaf of 180 Kg and
opening of 95°; K = 105).

tion between the line with the Ed value and the column with the K
value. The box contains the maximum possible number of cycles per
day (e.g. Ed = 2800 and K= 105; cycles per day ≈ 22).
