2.8 Functional 

diagrams

There are two possible showcase/cold/room confi gurations. The fi rst 
involves the various units being fi tted individually with their own 
compressor and condenser, meaning the showcase is completely 
independent, and shares the cooling water loop with the rest of the 
system. In the second case, the condenser is shared and consequently the 
Slave showcases are only fi tted with the evaporator and corresponding 
electronic expansion valve, while the compressor is controlled by the 
Master board.
The system confi gurations can be set from a terminal (pGDe) as illustrated 
in the chapter on Commissioning; while on the showcase itself a PLD is 
normally used to display the temperature and any alarm signals.
Defrosts can be coordinated via the pLAN that controls a maximum of 6 
units, or alternatively by the supervisor

1. 

Stand-alone confi guration 

In this case, each showcase/cold room has its own compressor, controlled 
by the corresponding board, which manages all system devices 
(expansion valve, showcase temperature control, alarms….).
The Master/Slave network is used for to coordinate defrosts, lights and 
curtain switch; otherwise these functions must be managed by the 
supervisor.

Note: 

For the electrical connections, see the general connection 

diagram in par. 2.9. If a master/slave network or multi-evaporator pLAN is 
confi gured, the controller addresses should be set following the 
procedure shown in chapter 9.1 or using the Wizard (chap. 5 
“Commissioning”)

2. 

Multi-evaporator Master/ Slave network

The Master controller manages the compressor and coordinates the 
functions of the 5 Slave controllers connected via the pLAN. Each Slave 
controller manages the individual showcase and has a PLD user terminal 
for temperature monitoring. Each controller, both Master and Slave, 
is connected to the supervisor network. The Master only shares the 
evaporation pressure, and not the corresponding temperature.
