Below is a description of the connections, confi guration parameters, UI graphics and operating modes
of the six codes available for the EVD4 in the different applications.
3.1 Application with µC 2 and µC 2 SE (EVD000*40* and EVD000*43*) via
tLAN
3.1.1 Connections
Communication: with reference to Fig. 3.1, connect GNX and RT+ to the µC 2 unit.
Confi guration: the EVD4-UI software is used to access the parameters; connect the converter
(CVSTDUTTL0 or CVSTD0TTL0) to the service serial port (Fig. 3.2).
Power supply: with reference to Fig. 3.3, connect G and G0 to the 24 Vac power supply side; to
connect an auxiliary battery see the EVD 4 Instruction Sheet.
Valve: with reference to Fig. 3.4, connect the valve according to the type set for the “Valve
type” parameter.
Probes: Connect the ratiometric pressure sensors and NTC temperature sensors to S1 and
S3 respectively.
For other types of probes or connections, change the value of the “EVD probes
type” parameter and see chap. 4
WARNING: if a EVD 4 unit is erroneously connected to a controller with a different communication
protocol (e.g. EVD000*40* with pCO via pLAN) and is then connected to a unit with the
same protocol (e.g. EVD000*40* with pCO or µC 2 via tLAN), the fi rst time that the EVD 4 is
connected with the correct protocol it may take a few minutes to recognise the protocol; if
this waiting time seems excessive, disconnect power to the controller and the EVD 4
(including any connections via CVSTDUTTL0 or CVSTD0TTL0 converter), and then
reconnect the devices (including any connection via CVSTDUTTL0 or CVSTD0TTL0
converter) and wait a few minutes for the connection to be restored independently. In the
event of connection to µC 2 , after having reconnected the devices to the power supply,
connect the EVD 4 to a PC and activate the EVD4_UI using the “EVD4_UI MCH2”
connection, set En. reset to default = 14797, then Reset to default = Yes (the box changes
from green to red).
