4.5 Connecting the terminal
The controller and the terminal are connected to a pLAN network.
1: One pCO controller
When connecting the controller to the terminal, the following restrictions
should be kept in mind:
1. the overall length of the pLAN network should not exceed 500 m.
Consequently, if the terminal is installed remotely the length of the
terminal cable must be included in the total length;
2. the unshielded telephone cable can be used for a max. length of 50
m. Beyond this length use a 3-pole shielded cable (see table below);
3. in case of lengths greater than 200 m, the power supply for the
terminal must be provided separately;
4.
no more than 3 terminals can be connected to the same pCO
controller. The terminals must be of the same type (e.g. all PGD1).
One terminal is powered by the controller, and the other two by an
external power supply;
5. except for PGD0/PGD1/PGDE, the other terminals should be powered
by separate power supplies.
Important:
•
In domestic installations, standard EN55014 requires the connection
cable between the controller and the terminal to be shielded, with the
shield earthed at both ends;
•
In industrial installations with length >10 m, the connection cable
between the controller and the terminal must be shielded and the
shield must be earthed.
Case A: 1 terminal
A.1: Distance L < 50 m.
The typical connection for one terminal (e.g. PGD1) is made using a
6-pin telephone cable available from CAREL as an accessory (code
S90CONN00*). The telephone connector provides both data transmission
and the power supply for the terminal.
To make the connection:
•
slip the connector into terminal J10 until it clicks.
To remove the connector:
•
press lightly on the plastic catch on the connector and slip it out.

A.2: Distance 50< L< 200 m.
Lengths greater than 50 m require using two TCONN6J000 boards
connected with a 4-pin shielded cable, as shown in the fi gure. The
terminal is powered by the controller.

A.3: Distance 200< L< 500 m.
The terminal must be powered by an external power supply. Connect a
3-pole shielded cable to connector pLAN J11. Provide a separate power
supply for board TCONN6J000, as shown in the fi gure.

Note: To reach the maximum length of the network use a bus
layout with branches not exceeding 5 m.
Case B: 2 terminals
Two terminals can be directly connected only on a Small model. Models
of other sizes require the second terminal to be powered separately. On
Medium/Large/Extralarge controllers apply the known confi guration A.1
or A.2 + A.3.
B.1: Distance L <50 m
Use 1 TCONN6J000 board connected as shown in the fi gure.
