ELECTRICAL CONNECTIONS

4.1 - ELECTRICAL CONNECTION TO THE CONTROL UNIT (Fig. 6)
01. Connect the various kit devices and any other components designed for being used on the system (optional and not included in the package) to
the control unit terminals (Fig. 7): for all accessories it is not necessary to observe any polarity, with the exception of the shielded aerial cable which
must be connected with the cable and sheath as shown. To connect the gearmotors refer to the detail in Fig. 8.

4.2 - CONNECTION OF THE MAESTRO300C and MAESTRO300M GEAR MOTORS

To make the electrical connections, remove the upper cover of the gear Motor as shown in fig. 6 - 6a.
• MAESTRO300M: insert the cable through the appropriate passage on the back of the gear motor and make the electrical connections as indicated
in fig. 6 - 6c and close the cover.
• MAESTRO300C: insert the cable through the appropriate passage on the back of the gear motor and make the electrical connections as indicated
in fig. 6 and close the cover.
Notes:
- to facilitate the connections, it is possible to remove the terminals fig. 6 - 6b; once the connections are completed, replace the terminals.
- to avoid the risk of the two doors getting stuck, the MAESTRO300C control unit first controls the motor connected to output M2 and then the motor
connected to M1, while the opposite occurs during closure. Therefore, make sure that the motor that operates the leaf resting on the mechanical
stop and on the M2 terminal of the upper leaf is connected to terminal M1 (more external).
- if only one motor is used (gate with only one leaf) it is necessary to connect it to terminal M2 leaving terminal M1 free.
- the grey (SbS) and red (stop) terminals of the KS200KIT key selector (optional accessory), must be connected respectively to the grey (SbS) and red
(stop) terminals of the control unit. There is no need to respect polarity in the connection.
- if using an external antenna (optional accessory), it is necessary to connect the central core and the shield of the antenna shielded cable as shown
in detail in fig. 6a.

4.3 - POWER SUPPLY CONNECTION

• For operational and programming tests of the automation, use the cable supplied, inserting the plug into an electrical socket. If the socket is a
long way from the automation, an extension may be used in this phase.
• For the testing and commissioning phase of the automation (definitive connection) the control unit must be connected permanently to the
mains power, by replacing the cable supplied with one of suitable length.
CAUTION! – The final connection of the system to the mains power or replacement of the cable supplied MUST be performed exclu-
sively by a qualified and electrician, in compliance with local safety standards and the following instructions.
- For installation outdoors, the entire cable must be protected with a protective tube; alternatively, the cable can be replaced with a type H07RN-F cable.
- The power line must be equipped with a device that ensures complete disconnection of the mains power to the automation. The disconnection de-
vice must have contacts with a sufficient gap to ensure complete disconnection, under the Category III overvoltage conditions, in accordance with the
installation instructions. If necessary, this device guarantees quick and safe disconnection from the mains power and therefore must be positioned in
sight of the automation. If located in a concealed position, it must be equipped with a system that prevents inadvertent or unauthorised reconnection
of power, to avoid potential hazards.

PROGRAMMING

5.1 - CONTROL UNIT KEYS

The control unit has three programming keys with their respective LEDs:
keys P1, P2, P3, P4 and LEDs L1, L2, L3, L4 (Fig. 9)
P1 = radio transmitter memorisation
P2 = slow/fast movement speed selection (Par. 5.6.1)
P3 = semi-automatic/automatic operating cycle selection (Par.
5.6.2)
P4 = automation movement command (SbS)

5.2 - PRELIMINARY CHECKS

After powering up the control unit, a few straightforward checks should
be carried out:
01. Check on the control unit (Fig. 10) that the ECSbus led flashes normally (roughly one flash each second).
02. On the Tx and Rx photocells (Fig. 11) check that the SAFE led flashes: the type of flash is unimportant as it depends on other factors; however,
it is important that the led is not always off or always lit.
03. If all these checks are non-conforming, disconnect the power supply to the control unit and check the relevant connections of the cables. Other
useful information is contained in Chapters 9.9 and 10.
