3.6. LIMIT SWITCHES

"LS" models are equipped with opening and closing limit switches.
Therefore they require the use of a control board able to control
these inputs.
Limit switches are triggered for the first and the last 30 mm of the
travel. Therefore the operator should use the whole available
travel during the opening phase. Shorter travels can limit or
completely cancel the limit switch adjustment range.

iRing the limit sWitChes
Limit switches are wired in the same terminal board where the motor
wiring has been carried out. Wire the limit switches as follows:
1. Open the second pre-drilled hole in the cover, Fig.17.
2. Fit the supplied cable gland, Fig.17.
3. Insert the cable and connect it to the terminals observing the
colours specified in the following table (with redo Figure 18).

4. Close the cover with the four supplied screws.
For limit switches connection use the cable for the external
movable laying with wires having a cross section of 0.5 mm
During the wiring operations, observe the wire colours as spe-
cified in the in the above table.

Limit switches adjustment is carried out as follows:
1. Unscrew the upper fastening screw, Fig.19 ref.a, and remove
the cap, Fig.19 ref.b.
2. PTo adjust the closing limit switch FCC turn the adjusting screw
clockwise, Fig.20 ref.a, to increase the rod stroke and counter-
clockwise to reduce it.
3. To adjust the opening limit switch FCA turn the adjusting screw
counter-clockwise, Fig.21 ref.a, to increase the rod stroke and
clockwise to reduce it.
4. Perform a pair of test cycles to check the correct position of the
limit switch. If the limit switches adjustment needs to be carried
out again, repeat the operation starting from point 2.
5. Riposition the cap, Fig.19 ref.b, and tighten the fastening screw
again, Fig.19 ref.a.
3.7. START-UP
Cut power before any job on the system or on the operator.
Carefully observe points 10, 11, 12, 13 and 14 of the SAFETY GENE-
RAL RULES.
With reference to the indications in Fig.3, set the ducts and carry out
the electrical connections of the control board and of the chosen
accessories.
Always separate power cables from control and safety cables (push
button, receiver, photocells, etc.). To avoid any electrical noise
whatever in the unit, use separate sheaths.
1. Power up the system and check the LED condition as shown in
the table of the control board instructions.
2. Program the control board according to the needs by following
the given instructions.
4. TESTING THE AUTOMATED SYSTEM
• Carefully check operating efficiency of the automated system
and of all accessories connected to it, paying special attention
to the safety devices.
• Hand the "User's Guide" to the final user together with the Main-
tenance sheet.
• Explain correct operation and use of the automated system to
the user.
• Indicate the potentially dangerous areas of the automated system
to the user.

5. MANUAL OPERATION

The reversible models R has no release device. To move the
leaf by hand, just release the electric lock.
Before releasing the electric lock always make sure that the
system is not powered.
If the automated system needs to be moved manually due to a
power lack or to an operator malfunction, proceed as follows:
1. Cut power by means of the safety circuit breaker (even in the
event of a power lack).
2. Slide the protective cap, Fig.22/a.
3. Insert the key and turn it 90°, Fig.22/b.
4. Lift the control lever, Fig.22/c.
5. To release the operator turn 180° the control lever to the direc-
tion indicated by the arrow on the release system, Fig.22/d.
6. Open and close the leaf manually.
To hold the operator in manual operation the release device
should be left in its current positions and the system should
be without power.
5.1. RESTORING NORMAL OPERATION
To restore normal operating conditions, proceed as follows:
1. Ensure that the system is not powered.
2. Turn the release system 180° in the opposite direction of the arrow.
3. Turn 90° the release key and remove it.
4. Close the control lever and the protection cover.
5. Power up the system and perform some movements in order
to check the correct restoring of every function of the auto-
mated system.
6. MAINTENANCE
In order to ensure correct operation and constant safety over time,
make a general check of the system every six months, paying special
attention to the safety devices. In the booklet "User guide", a form
has been prepared for the recording of maintenance operations.
7. REPAIRS
The user must not carry out any repairs or maintenance operations;
these must be effected only and exclusively by qualified personnel.
