6.2.2 MEMORY STORAGE OF BUS-2EASY ACCESSORIES
You can add the BuS-2EASY accessories to the system at any
time, simply by memory-storing them on the board, observing
the following procedure:
Install and program the accessories using the required
address (see parag. 6.2.).
Cut power to the board.
Connect the two cables of the BuS-2EASY accessories to
the red terminal-board J3 (any polarity will do).
Power the board, taking care to first connect plug J of the
main power supply (coming from the switching feeder) and
then, connector J2 of any batteries.
Quickly press once only the SETuP (SW3) push-button,
to execute learning. Check operation of the installed
BuS-2EASY devices.
The board has memory stored the BuS-2EASY accessories.
Follow the instructions in the table below to check if the
BuS-2EASY connection is correct.

error, repeat the acquisition procedure. If
the error is repeated, make sure that there
is not more than one accessory with the
same address in the system (also see the
accessories instructions).

6.2.3 ADDRESSING THE BUS-2EASY ENCODERS
Connection of the BuS-2EASY input in the control board is via
the bipolar cables which come out of the encoders.
Unlike the case of the photocell devices, the
polarity of the BUS-2EASY line connection
determines whether the encoder belongs to
one leaf rather than to the other.
This is why you must pay great attention to the indications of
the status LEDs on the body of each encoder (Fig. 26).
Below we list the functions of LEDs DL, DL2, and DL3, and their
statuses:

DL 1
must always be lighted to guarantee correct
connection between encoder and board.
DL 2
determines the leaf on which the encoder is installed.
Providing the configuration is correct, the automated
system will show: an encoder with DL2 lighted in leaf
, and an encoder with DL2 OFF in leaf 2. If there is an
incorrect connection, i.e. indicating two encoders with
the same status of the DL2 LEDs, during the learning
procedure of the BuS-2EASY accessories, the DL LEDS
of both encoders show a FLAShING status. In this situation,
refer to the configuration in TAB.4 to define which encoder
connection to rotate.
DL 3
indicates, on a steady flashing beam, the reading
of the pulses while the leaf is moving. When the leaf is
motionless, DL 3 can be either lighted or OFF.
