2. A screen will appear showing the terminal and board address.

Terminal Adr: 16

I/O Board Adr: n

3. Using the “Up” and “Down” keys, it is possible to choose the different board (1, 2, 3, 4 for the compressors and 5,

7, 9, 11 for the electronic valve drivers)

4. Select 1 for “I/O Board Adr” (Board with address 1) and push “Enter”. In about two seconds the following screen

Terminal Config

Press ENTER

To continue

5. Press “Enter” again; the following screen will appear:

P:01 Adr Priv/Shared

Trm1 16 Sh

Trm2 None --

Trm3 None -- Ok? No

6. If you had to add a second terminal (remote terminal), change the line “Trm2 None –“ with the line “Tmr2 17 sh”.

To enable the new configuration, put the pointer on “No” (using the key “Enter”) and with “Up” and “Down”

change it to “Yes” and push “Enter”.

The operations 1 through 6 must be repeated for all the compressor boards (“I/O Board” from 1 to 4)

At the end of operations turn off and restart the system.

Remark:

It is possible, after restart, that the terminal is stuck on a unit. This is due to the fact that the memory of the Drivers

remains fed by the buffer battery and retains the data of the preceding configuration. In this case, with the system power

supply off, it is sufficient to disconnect batteries from all the drivers and then connect them again.
