INTEGRATED FLASHING LIGHT
Slight has an integrated flashing card which can be connected to the Flash or
S.C.A. output on the control unit. In order to program these functions, refer to
paragraph "8.5 Level 2 programming".

FINAL CHECKS AND START UP
The manufacturers recommend you position the leaf at approximately half trav-
el before starting the checking and start up phase of the automation. This will
ensure the leaf is free to move both during opening and closure.
6.1 - Selecting the direction
The direction of the opening manoeuvre must be chosen depending on the
position of the gear motor with respect to the leaf. If the leaf must move left
for opening, the selector must be moved towards left as shown in the Figure,
alternatively, if the leaf has to move right during opening, the selector must be
moved towards the right as shown in the Figure.
6.2 - Connecting to the power supply
WARNING! – Connecting SLIGHT to the power supply must only be
performed by qualified and experienced personnel in possession of
the necessary requisites and in full respect of the laws, provisions and
standards currently in force.
As soon as SLIGHT is energized, you should check the following:
01. Check that the BlueBUS led flashes regularly at the frequency of one flash
per second.
02. Make sure that the LEDs on the photocells flash (both on TX and RX); the
type of flashing is not important as it depends on other factors.
03. Make sure that the flashing light connected to the FLASH output and the
indicator light connected to the "Open Gate Indicator" output are off.
If the above conditions are not satisfied, you should immediately switch off the
power supply to the control unit and check the electrical connections more
carefully.
Please refer to chapter "10.1 Troubleshooting" for useful information on search-
ing for and diagnosing failures.
6.3 - Recognition of the devices
After connecting up the power supply, the control unit must be made to rec-
ognise the devices connected up to the BLUEBUS and STOP inputs. Before
this phase, LEDs L1 and L2 will flash to indicate that recognition of the devices
must be carried out.
01. Press and hold keys [s] and
[Set].
02. Release the keys when LEDs L1
and L2 start to flash quickly (after
around 3s).
03. Wait a few seconds until the con-
trol unit has completed the device
recognition procedure.
04. When the recognition stage is
completed the STOP LED must
remain on, while the L1 and L2
LEDs must go off (LEDs L3 and
L4 may start flashing).
The connected devices recognition stage can be repeated at any time,
even after the installation (for example, if an additional device is installed);
please see paragraph "9.1.6 Recognition of other devices" in order to per-
form a new recognition.
6.4 - Recognition of the length of the leaf
After recognizing the devices, L3 and L4 LEDs start flashing; the control unit
must recognize the length of the gate. During this stage, the length of the leaf is
measured from the closing limit switch to the opening limit switch. This meas-
urement is required to calculate the deceleration points and the partial opening
point.
01. Press and hold keys [s] and
[Set]
02. Release the keys when the
manoeuvre starts (after approx. 3
s).
03. Check the manoeuvre in pro-
gress is an opening manoeuvre.
Otherwise, press the [Stop] key
and carefully check paragraph
"6.1 Selecting the direction"; then
repeat the process from point 1.
04. Wait for the control unit to fully
open the gate by reaching the
opening limit switch; the closing
manoeuvre will start immediately
afterwards.
05. Wait for the control unit to fully
close the gate.
If the above conditions are not satisfied, you should immediately switch off the
power supply to the control unit and check the electrical connections more care-
fully. Other useful information can be found in the chapter "10.1 Troubleshooting".
If it is necessary to adjust limit switch positions more finely, use the 2 adjust-
ment knobs (fig. 15 and 16) in ther gear motor, as follows:
01. Press the s or t key on the control unit to open or close the leaf, on the
basis of the position to be defined.
02. Remove the cover that blocks the 2 adjustment knobs (fig. 15).
03. Identify the adjustment knob with the arrow indicating the direction of the
limit switch to be adjusted and turn it half a turn (equal to about 3 cm of
movement of the gate) fig. 16.
04. Next, on the control unit, press keys or key t again to open or close the
leaf to register the new position. Repeat as necessary until the leaf reaches
the desired limit switch.
WARNING! – If it is necessary to define the position of the limit switch with
greater precision, move the leaf back a few centimetres by giving the opening
or closing commands (s or t) on the control unit and then send the command
in the direction to be checked.
Note – If you have already performed manual adjustment and need to repeat
the entire procedure, you can return the limit switches to their initial condition
by turning the 2 adjustment knobs toward the "–" sign until the microswitches
are tripped (fig. 16). Then repeat the entire limit switch adjustment procedure.
Important – If, at the start of the installation phase, the leaf is not in the correct
position midway along its travel when the motor is anchored in place and the
pinion is moved along the rack, it may be necessary to reduce the position of
the limit switch on one side.
In this case, if the leaf opens until it hits the retainer, without complying with
the set position, turn the adjustment knob (identified by an arrow indicating
the direction in which the door moves) toward the "-" sign until the limit switch
is tripped. After this, oversee adjustment of the unit again and use precision
adjustment if necessary.
If necessary, adjust the door length again.
6.5 - Checking gate movements
On completion of the recognition of the length of the leaf, it is advisable to carry
out a number of manoeuvres in order to check the gate travels properly.
01. Press the [Open] key to open the gate. Check that gate opening occurs
correctly, without any variations in speed. The leaf must only slow down
when it is between 70 and 50 cm from the opening limit switch, and stop,
as a result of the limit switch, at 2-3 cm from the mechanical opening stop.
02. Press the [Close] key to close the gate. Check that gate opening occurs
correctly, without any variations in speed. The leaf must only slow down
when it is between 70 and 50 cm from the closing limit switch, and stop, as
a result of the limit switch, at 2-3 cm from the mechanical closing stop.
03. During the manoeuvre, check that the flashing light flashes at a speed of
0.5 seconds on and 0.5 seconds off. If present, also check the flashes of
the light connected to the S.C.A. terminal: slow flashes during opening,
quick flashes during closing.
04. Open and close the gate several times to make sure that there are no
points of excessive friction and that there are no defects in the assembly or
adjustments.
05. Check that the fastening of the SLIGHT gear motor, the rack and the limit
switch brackets are solid, stable and suitably resistant, also when the gate
accelerates or decelerates sharply.
