1 WARNINGS
Before attempting any work on the control board (connections, maintenance), always turn off power.
Install, upstream of the system, a differential thermal breaker with adequate tripping threshold.
Connect the earth lead to the appropriate terminal. |
Always separate power cables from control and safety cables 
(push-button, receiver, photocells, etc.). To avoid any electric noise, use separate sheaths or a shielded cable (with earthed shield).

Before connecting the photocells, it is advisable to select the type of operation on the basis of the area of movement that they need to protect:
Safety devices during closing: operate only during the automated system closing movement and are therefore suitable for protecting the closing area from the risk of impact.
Safety devices during opening: operate only during the automated system opening movement and are therefore suitable for protecting the opening area from the risk of impact.
Safety devices during opening/closing: operate during both the automated system opening and closing movements and are therefore suitable for protecting the entire movement area from the risk of impact.

4.1 BUS-2EASY PHOTOCELLS
This board is equipped with a BUS-2EASY circuit that can be used to easily connect a high number of auxiliary BUS2EASY devices to the safety device (e.g. up to 16 pairs of photocells), appropriately programmed, using only two cables without polarity.
Before connecting the photocells, it is advisable to select the type of operation (Fig. 3) on the basis of the area of movement the cells must protect and to position the dip switches on both the transmitter and receiver (see Fig. 4) as in Tab. 1.
4.1.1 ADDRESSING BUS-2EASY PHOTOCELLS
It is important to give both the transmitter 
and the receiver the same address.
Ensure that there are not two or more pho- |
tocell pairs with the same address. |
If no BUS-2EASY accessory is used, leave the |
BUS-2EASY connector (J12 - fig. 1) free. |

4.1.2 STORING BUS-2EASY ACCESSORIES
At any time it is possible to add BUS-2EASY photocells and accessories to the system, simply by following the procedure below:
1.Install and programme the accessories with the required address (see par. 4.1.1).
2.Cut off power to the board.
3.Connect both cables of the BUS-2EASY accessories to the red terminal block J12 (polarity irrelevant).
4.Power the board.
5.Quickly press the SETUP push-button (SW4) once to register the accessories. Check the operation of the installed BUS-2EASY devices.
6.The board has stored the BUS-2EASY accessories.
Follow the instructions in the following table to check that the BUS-2EASY connection status is efficient.
The same procedure must be performed on a
MASTER unit also when acquiring a SLAVE unit connected to the BUS2EASY with POLARISED connection

If the FAIL-SAFE safety device is not
used, connect the power supply of the transmitters to terminals 6 and 8 of J13.
If the FAIL-SAFE safety device is used, connect
the power supply of the transmitters to OUT after setting it as appropriate (see 2nd level programming and Fig. 5).
If the FAIL-SAFE safety device is used, even the 
unused safety inputs must be connected via a shunt lead to the negative of OUT (see Fig. 5).
