PRELIMINARY NOTES FOR THE INSTALLER: COMPARISON BETWEEN pCO
• the pCO 3 family controllers do not have the connector using the programming key code PCO201KEY0. To program the controller, use the new Smart
Key (PCOS00AKY0) available from September 2005. Otherwise use WinLoad ver. 3.35 and higher:
An application cannot be run from the Smart Key;

• unlike the pCO , there is no fuse between J1 and J2. All pCO
No external fuse is required;
• a further terminal J24 (in place of the fuse) is provided for the power supply to the ratiometric probes (+5 VREF), as well as 20 Vdc to supply a secondary
terminal, such as the aria terminal (TAT***), in alternative to the standard one;
• the terminal J11 (connection to the pLAN network) in the fi rst prototypes of the pCO
• the LEDs near the dipswitches for setting the pLAN address have been moved between connectors J3 and J4;
• the red probe power supply overload LED has been removed.
