9.4 BUS 2EASY DEVICES
This board has a BUS 2easy circuit for connecting
BUS 2easy devices (photocells, control devices).
L
i
If no BUS 2easy accessories are used, leave the
BUS 2easy connector free. Do not bridge.
CONNECTION
) Connecting any devices BUS 2easy (photo-
cells and command devices) to terminal J3.
L
i
The overall length of the BUS 2easy cables must not
exceed 100 m.
The BUS line does not require a matching polarity
connection.
BUS 2EASY PHOTOCELLS
Type of use:
Closing pho-
tocells
Active during
closing
When an obstacle is de-
tected, they stop the beam
and reopen it.
Photocells
used as pulse
generators
Always active
When an obstacle is de-
tected, they send an OPEN
command
1. Assign an address to the BUS 2easy photocells.

Assign an address to each pair of photocells by setting
the four DIP switches (DS1) on the transmitter and the
corresponding receiver.
L
i
The transmitter and receiver of a pair of photocells
must have the same DIP switch settings.
There must never be two or more pairs of photocells
with the same DIP switch settings. If there is more
than one pair of photocells with the same address, a
conflict error is generated.
2. Register the BUS 2easy photocells (
bu
Basic pro-
gramming).
3. Check the status of LEDs DL3 and DL7 (
).
4. Check that the photocells are operating cor-
rectly. When the beam is moving, interrupt it with
an obstacle and check the LEDs on the photocells,
the status of the bus on the display and the auto-
mation system operate according to the type of
photocell installed.
CONTROL DEVICES
1. Position the DIP switches to assign the commands.
L
i
Stop NC also generates a stop when the device is
disconnected. A command (e.g.: OPEN A_1) must
be used on only one of the connected devices.
