Example: composition of a process image

in the Bus Coupler

Plug the terminals into the coupler in the sequence that can be seen in the

picture, and set address 2 at the "station address" DIP switch.

Connect the 24V /0V and the +/- contacts to the 24V DC supply voltage,

and switch the supply voltage on.

The 2 green LEDs at the supply assembly should now illuminate. If this is

not the case, the voltage must be checked.

Connect the BK7500 SERCOS Coupler to the SERCOS Master with the

optical fibre. The master's sender must be connected to the receiver at the

BK7500, and the sender at the coupler must be connected to the master's

receiver.

Examine the length of the cable between the BK7500 sender and the

SERCOS master receiver, and set the DIP switch for "cable length" (see

label on the Bus Coupler) correctly.

The same setting is required at the master end.

If the SERCOS Master is already active (detectable from the red light at the

SERCOS Master Sender) the "LWL" LED at the BK7500 should go out,

provided the connections are correct.

You must check the optical fibre if this LED continues to shine.
