Installation Of The Various Devices To The Control Unit; Electrical Connections; Operating Control; Power Supply Connection - Nice Tub Instructions Et Recommandations Pour L'installateur

3.3) Installation of the various devices to the control unit.

Perform the installation of all foreseen devices following the respective instructions. Check which devices can be connected to the TUB3500
from the "MindyA500" manual.

3.4) Electrical connections

!
The electrical connections must be performed by skilled
and qualified personnel in strict observance of current legis-
lation, standards and regulations with the system disconnect-
ed from electricity supply.
1. The two yellow plastic screws must be removed in order to open
the control unit door and access the electronic control board of
the TUB3500.

4) Operating control

Position the gate approximately halfway along its total travel so that is can be easily opened or closed before performing the control and start-
ing the automation.

4.1) Power supply connection

!
The connection of TUB3500 to the mains must be made 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 power is supplied to the TUB3500 by means of the
magneto-thermal switch on the power unit, check that the OK Led
in the centre of the unit starts to flash and that the Photo input led
is on.

4.2) Direction control

For motors with three-phase power supply, the direction in which the
motor moves depends on the connection of the 3 power supply
phases, therefore it is impossible to see before hand if the motor
turns in the desired direction and if the limit switches intervene in the
required direction.
It is necessary to perform the controls following the procedure below
to set-up the movement direction.
a. Motor direction control:
Position the gate half open and give an impulse command on the
Open input of the A500 control unit (terminal 20) and check if the
gate actually performs an opening movement. If the direction is
correct pass to the next point, otherwise turn off the power to the

4.3 Gate movement control

Once the limit-switch brackets have been secured (Fig. 4) in the
rack, perform a few manoeuvres to make sure that the gate is mov-
ing correctly.
1. Control an opening manoeuvre:
a. Make sure the gate opens with an even speed;
b. Make sure that the limit-switch bracket (Fig.4) activate the micro-
switch, stopping the leaf with a maximum movement of 2-3 cm
(be careful because the time required for the leaf to stop may
increase when hot).
c. When the gate has stopped moving, check that it finished 4-5cm
away from the end stop.
2. Control a closing movement: as in point 1 .
3. If the stopping distance of the gate is greater than 2-3 cm, adjust
the mechanical brake as shown in paragraph "5.1 Testing".

2. Cut the cable slop, positioned beneath the control unit, to the
correct size so that all the electrical cables can pass through.
3. Secure the cables with a couple of cable clips.
4. To perform the electrical connections, carefully follow the control
unit instructions in the "mindyA500" manual.
• Now push the microswitch lever, which is positioned to the right of
the electric motor, and check that the ALT led and the FCA and
FCC limit-switch leds light.
• If this does not happen, turn the power off straight away from the
control unit and check carefully the electrical connections.
• Further troubleshooting information can be found in the
"mindyA500" control unit manual.
control unit straight away and invert the cables on terminals 3 and
4 of the A500 terminal block, then check the direction of the
motor once again.
b. Limit-switch intervention control:
During the opening manoeuvre of the motor and before the gate
is completely open, simulate the intervention of the limit-switch in
the required direction and check that the manoeuvre stops, if this
does not happen, turn off the power to the control unit and invert
the connections of terminals 10 and 12 of the A500 terminal
block, then perform the control of the limit-switch intervention
once again.
4. Perform a number of opening and closing manoeuvres to high-
light possible fitting and adjustment errors or other errors such as
points of greater friction.
5. Make sure that the TUB3500 gear motor, rack and limit-switch
brackets are well secured, stable and adequately resistant espe-
cially during the sharp starting and stopping movements of the
gate.
