Setting Up Scan Codes; Choice Of Reset Procedure - ABB Focus II FII-4-14 Series Original Instructions Manual

4.5 Setting up Scan Codes

The Focus II transmitter and receiver has the possibility of coding selection, to minimize interference when
two transmitters can reach one receiver.
NB! Both transmitter and receiver shall be set to the same code. All LEDs on transmitter / receiver flash
twice when code B is set correct, when powering up. Code A will flash once. Please make sure that the total
length of the cable between the transmitter and receiver (required when coding is used, see 5.6) does not
exceed 100 m.
