Address Setting

Use a 10-pin rotary switch 0–9 (see the figure above) to set the I/O Module address for a

lift. Set 1–8 like the shaft number for the splitter (set 5 for lift 5, e.g.).

Warning

Do not set address 0 and 9 to avoid system error.



The I/O Module is equipped with ten LED indicators: two I/O Module status signalling

LEDs, four input status signalling LEDs and four output status signalling LEDs. Refer to the

table for details.

Up to 4 galvanically isolated logic inputs can be connected to each I/O Module. The

nominal voltage of these inputs is 12–24 V. The minimum detectable level is 8 V and the

maximum level may not exceed 30 V. Otherwise, the I/O Module input circuits will get

damaged. Transition to state 1 occurs with the logic signal rising edge and transition to

state 0 with the falling edge. Every transition is detected and displayed in

the 2N

Service Tool application. At the same time, every status change is recorded in

the system log for later use and the user is informed via a pop-up window. See the figure

below for an example of input circuit connection.

If everything is OK, the power supply and bus are connected, the I/O Module is

communicating with the CU, the LED is flashing.

If the red LED is on, the bus is not connected or there is an address collision with

another I/O Module in the system.

This LED is on when the given input is active, i.e. nominal voltage for detection of logic 1

is detected on it.

This LED is on when the given input is active, i.e. the given relay is closed.
