6.1) Disposal

This product is made from various kinds of material, some of which can
be recycled. Make sure you recycle or dispose of the product in com-
pliance with current laws and bye-laws.

7) Battery operation

The control unit contains a large enough transformer to cater for the power requirements of the motor and the electronic board when directly pow-
ered by the mains supply. If the system is required to work even when mains power is unavailable, suitable batteries should be connected. When
mains power is used, the control unit charges these batteries, while when mains power is unavailable, the control unit automatically switches to
the battery mode.
Tabella "N" Connecting the batteries
1. Before connecting the batteries, install the system and make sure everything works correctly.
2. Check that the battery led is on and that voltage at the terminals is approximately 27 volt.
Perform the next operation with great care as it involves working on live circuits.
!
3. Connect the batteries as shown in Fig. 6.
4. Immediately after connecting the batteries to the control unit, check that the battery led is still on; if it is off, disconnect the batteries
immediately and check the polarity of the connection.
5. If the battery led is on, check the voltage on the battery terminals again; if voltage is:
• lower than 18 Vdc, the batteries are not connected correctly or they are faulty
• between 18 and 25 Vdc, the batteries are flat; wait for them to recharge
• higher than 25 Vdc, the batteries are charged, disconnect mains power, check the system continues to work correctly and then
reconnect mains power.
N.B. In the battery mode, the motor moves more slowly than when the control unit is powered by the mains.
N.B. 1. If both power systems are present (mains power and batteries) and you want to disconnect the power unit for maintenance or safety
purposes, as well as disconnecting mains power, you must also disconnect the batteries or remove the F4 battery fuse on the control unit.

8) Radio receiver

The control unit features a connector for plugging in a radio receiver
(optional accessory) which activates the Step-by-Step input and allows
the control unit to be remote-controlled with a transmitter. The clean
contact for the second channel is available on terminal 41-42.
Some electronic components may contain polluting
!
substances; do not dump them.
Before fitting the receiver, disconnect mains power and any batteries
and plug in the receiver with its components directed towards the con-
trol unit microprocessor.
