 C-Ring : communication between controllers

 

(for detailed information please see technical data sheet T 022)

 

XSE 602 controller can only be 

“Slave”

.

In C-Ring the following signals are transmitted : 

– permission for controllers to operate.  

– value of the 

outside temperature

 (use of a single detector for several controllers)

–  value of 

flow temperature

 requested by controllers; used by  “PRIMARY” controller for control 

of temperature boilers (if foreseen).

– 

DHW priority

 and / or 

anticondensing

 = closure valves heating zones by modulating control 

action.

 C-Bus communication for telemanagement

 

(for detailed information please see technical data sheet T 021) 

XSE 602 provides : 

– remote Telemanagement by when enabled by 

C-Bus Plug-in type ACB 400 C1

– local communication (e.g. setting via PC) when enabled with Test 

Plug-in ACX 232

Telemanagement is bidirectional, with one or more local PCs and/or the remote central PC via 

PSTN. 

Local communication is direct to a portable PC to be connected directly to the unit.

From PC or PCs it is possible to display and/or change :

– the data and values entered on display pages of the controller and those of configuration 

dedicated exclusively to telemanagment (see 4.TECHNICAL DATA)

– operational status of plant components (pumps, auxiliaries in general)

– acquire alarms coming from boiler plant

– read the measurements of the detectors (temperatures : outside, flow, boiler, etc)

10.

4

 C-Bus electrical connection for local or remote Telemanagement

 

Each  controller  must  be  equipped 

with the C-Bus Plug-in of the required 

type for the controller in question

10.

5

 Connection to PC for local communication via test Plug-in ACX 232

Extract the C-Bus Plug-in and insert the test Plug-in ACX 232; use a standard cable to connect the RS232 plug to 

the PC (the cables are included in the “CONVENIENCE KIT”.

If the PC has only USB inputs use a standard RS232 to USB conversion cable.

Observations

 : – Before communicating, ensure that the address entered in the controller is the address with which you wish 

to communicate via PC.

 

– It is advisable to use a portable PC powered by battery with the connection to 230 Volts unplugged (or 240 V 

AC for UK market), since the earth (0 volts) of the controller is connected to that of the RS 232 and so to that 

of the PC.  By connecting the two earths together you could have dispersed currents, if the earths have not 

been well made and if the PC has its 0 volt connected directly to the central pole of the plug (as is usual)

ACCESSORIES:

–Test  Plug-in = 

ACX 232

–Convenience kit = 

KIT RS 232

The “Convenience kit” contains 

the 2 cables & other useful ac-

cessories.
