tion of the lower leaf motor compared with the upper one This is necessary
in order to prevent the leafs from getting stuck. There is always a standard
delay during closing, calculated automatically by the control unit in order to
ensure the same delay as the one programmed for opening.
5.2.3 - Level one programming: part two
• Stand By / Phototest function: The control unit has the "Everything in
stand by" function preset. If this function is active, 1 minute after the end of
a manoeuvre the control unit turns off the "Everything in stand by" output
(terminal no. 8) and all the Inputs and other Outputs to reduce consumptions
(see electrical diagram in fig. 5a). This function is obligatory if the control
unit is powered exclusively with Solemyo photovoltaic panels. It is also rec-
ommended if the control panel is powered from the electric mains and if
you wish to extend emergency operation with the buffer battery PS124. As
an alternative to the "Everything in stand by" function, the "Phototest" func-
tion may be activated. This verifies at the beginning of a manoeuvre that the
connected photocells operate correctly. To use this function, connect the
photocells correctly (see electrical diagram in fig. 5c) and then activate the
function.
• Open gate indicator light / electric lock: If the function is activated, termi-
nals 6-7 can be used to connect up the electric lock. If the function is deacti-
vated, terminals 6-7 can be used to connect up a 24V gate open indicator.
• NC Type or Constant Resistance STOP Input: If the function is activated,
the STOP input is set to "8.2KΩ Constant Resistance". In this case, there
must be a 8.2KΩ +/-25% resistance between the common and the input to
enable the operation. If the function is not set, the configuration of the STOP
input will enable it to function with NC type contacts.
• Light/heavy gates : If the function is activated, the control unit enables the
user to manage heavy gates, setting the acceleration ramps and slowdown
speeds during closing differently. If the function is deactivated, the control
unit will be set to manage light gates.
• Proportional gate open indicator: If the function is activated, the gate open
in d icator output will be set with the proportional flashing light. This means
that during opening, the flashing becomes more intense as the leafs come
nearer to the opening stops; vice-versa, for closing, the flashing becomes less
intense as the leafs come nearer to the closing stops. If the function is deacti-
vated, the light will flash slowly during opening and rapidly during closing.
5.2.4 - Level two functions
• Pause time: The pause time, namely the time which lapses between open-
ing and closing during automatic functioning, can be programmed to 5, 10,
20, 40, and 80 seconds.
• Auxiliary input AUX: The control unit offers an auxiliary input which can be
set to carry out one of the following 6 functions:
- Partial opening type 1: this carries out the same function as the STEP-
BY-STEP input . It causes only the upper leaf to open . It only works if the gate
is closed completely, otherwise the command is interpreted as if it were a
STEP-BY-STEP comman .
- Partial opening type 2: this carries out the same function as the STEP-
BY-STEP input . It causes the two leafs to open for half the time it would take
them to open completely . It only works if the gate is closed completely, oth-
erwise the command is interpreted as if it were a STEP-BY-STEP command .
- Open only: this input only causes opening in the Open-Stop-Open-Stop
sequence .
- Close only: this input only causes closing in the Open-Stop-Open-Stop
sequence .
- Photo 2: this carries out the function of the "PHOTO 2" safety device .
- Disabled: the input will not carry out any function
• Discharge time: At the end of the Closing manoeuvre, after the leafs have
reached the totally closed position, the motor continues to "push" the leaf for
a brief interval, to ensure perfect closure. Immediately afterwards, this func-
tion activates a very brief inversion of movement to reduce excessive pres-
sure exerted by the motor on the leafs.
• Current sensitivity: The control unit is equipped with a system which meas-
ures the current absorbed by the two motors used to detect the mechan-
ical stops and any obstacles when the gate is moving. Since the current
ab sorbed depends on a number of conditions, including the weight of the
gate, friction, wind and variations in voltage, the cut-in threshold can be
changed. There are 6 levels: 1 is the most sensitive (minimum force), 6 is the
least sensitive (maximum force).
By increasing the amperometric sensitivity level the deceleration speed
increases during the closing phase of the manoeuvre.
WARNING! – If the "current sensitivity" function (together with other
vital features) is adjusted correctly, the system will comply with Euro-
pean standards, EN 12453 and EN 12445, which require techniques or
devices to be used to limit force and danger during the functioning of
automatic gates and doors are moved.
• Leaf delay: The delay in starting up the motor of the lower leaf can be pro-
grammed to 5, 10, 20, 30 or 40% of the working time.
5.3 - Programming
All the functions described in paragraph 5.2 "Programmable functions" chap-
ter can be selected by means of a programming phase which terminates by
memorising the choices made. The control unit therefore has a memory which
stores the functions and parameters relative to the automation process.
The P1, P2 and P3 buttons are used for all the programming phases, while the
5 LEDs (L1, L2...L5) indicate the selected parameter.
There are two different programming levels:
• At level 1, the functions can be enabled or disabled. Each Led (L1, L2...L5)
corresponds to a function: if the Led is on, the function is active; if it is off, it
is deactivated.
Level one consists in 2 parts which can be selected using the P3 button. The
cor responding LED P3 indicates which of the 2 parts has been selected.
Level one (P1 Led lit): part one ( P3 Led off)
L1 Led L2 Led L3 Led
Closing Function Pre-flash

Level one (P1 Led lit): part two (P3 Led lit)

• It is possible to pass to the second level from level one of part one. At this
second level the user can choose the parameter relating to the function. A
different value corresponds to each LED which must be associated to the
parameter.
