User Terminal Connection; Valve Control - Carel μPC Technical Leaflet

2.8 User terminal connection

The maximum distance between the μPC and user terminal is shown in the following table.
cable type
telephone
AWG24 shielded cable
Note:
•
a maximum of one terminal (pGD0, pGD1, pGD-i) can be connected;
•
the graphic terminal and other terminals are always powered with a separate power supply;
•
only one terminal (the PLD terminal to connector no. 3 or alternately th-Tune to connector n.ro 4) can be
connected, if the maximum cable-lenght is < 10m;
•
the protocol supported (RS485 / tLAN protocols) is confi gured by the 3-pin jumper.
Both are not available at the same time (RS485 / tLAN protocols).

Note:
•
the UPC*****M* model can manage two diff erent valves. The 2 valves cannot run simultaneously but
in sequence;
•
only one valve can be connected to each connector;
•
the step frequency is selected by software;
•
select the right valve to heve better performances.
