2.3.4) Photo-test

The control unit of the SP6000 features the "Photo-test" function.
This is an excellent solution as regards the reliability of safety devices
and puts the control unit + safety device assembly into "category 2"
as per UNI EN 954-1 standard (ed. 12/1998). Whenever a manoeuvre
is begun, the relative safety devices are checked and only if
everything is in order will the manoeuvre start.

2.3.5) Checking connections

the next operations involve work being done on live
circuits, some parts have mains voltage running through
them and are therefore EXTREMELY DANGEROUS! Pay the
greatest of attention to what you are doing and NEVER
WORK ALONE!
After making connections, the whole system must be checked.
• Power the control unit and check that the OK Led flashes rapidly for
a few seconds.
• Check that there is a voltage of 24Vac on terminals 3-4, 3-6, 3-7 and
that there is a voltage of 0Vac on terminals 3-8; if this is not the case,
unplug the unit immediately and carefully check the connections and
the voltage input.
• After the initial rapid flashing, the OK Led shows the control unit is
working correctly by flashing regularly at 1 second intervals. When
there is a variation in the inputs, the OK Led flashes rapidly twice to
show that the input has been recognised. When the photocells

3) Programmable functions:

The unit features two buttons used to programme various operating
modes so as to make the system more suitable to user needs and
safer in various conditions of use.
The control unit has two operating modes: semiautomatic and
automatic.
"Semiautomatic" Mode:
In this mode, a command impulse on the "Step-by-step" input makes
alternative opening and closing manoeuvres according to the "Open
– Stop – Close – Stop" sequence.
"Automatic" Mode:
In this mode, after an open manoeuvre, a programmed pause takes
place (by setting the pause time) after which the closing manoeuvre
is carried out.

All this is only possible if a special configuration of the safety device
connections is used; in practice, the "TX" photocell transmitters are
powered separately from the "RX" receivers.
N.B.: when "Photo-test" is active, the photocell transmitter is only
powered during the manoeuvre.
detect an obstacle, the OK Led flashes rapidly twice, as it also does
when the "Stop" input is deactivated.
• Carry out a test with the door disconnected from the motor; perform
a brief opening and closing cycle and press the "Step-by-step"
button to check the mechanical parts are in working order. (The first
manoeuvre made after the unit is powered is always "Open"). At the
end of the cycle, reconnect the door to the drive trolley.
• Then position the limit switch slides as shown in Fig. 3.
Press the "Step-by-step" button and check that the door moves in the
opening direction. Press the step-by-step button when the door is 1
cm from the opening point, thereby stopping the manoeuvre; then
insert the "Open" travel stop slide on the edge of the cover. Press the
"Step-by-step" button again and check that the door moves in the
closing direction. Press the "Step-by-step" button when the door is 1
cm from the closing point, thereby stopping the manoeuvre; then insert
the "Close" travel stop slide on the edge of the cover.
Current sensitivity:
The control unit features a system measuring the current absorbed by
the motor and uses this to detect obstacles.
Given that the absorbed current depends on variable conditions
(weight of door, various kinds of friction, gusts of wind, voltage
variations, etc.) the cut-in threshold can be changed.
There are five levels: no. 1 is the lowest (minimum power), no. 5 is
the highest (maximum power). Initially it is set at level 3, which should
be the optimum one for most installations.
!
The "current sensitivity" function, suitably adjusted
(together with other vital features) allows the system to
comply with recent European standards, EN 12453 and EN
12445, which require techniques or devices to be used to
limit force and danger when automatic gates and doors are
moved.
