3.6.5 EVD4_UI user interface
The EVD4_UI user interface is based on the CAREL supervisor protocol and is designed for the easy
and intuitive reading or confi guration of the control parameters. The program can be started in different
confi gurations so as to display the set of parameters that is suitable for the type of installation the EVD4
is used in; to do this, make the connection using the name of the required confi guration.
The interface confi guration for the ‘positioner’ function is shown in Fig. 3.21 and is activated by making
the “EVD4_UI stand alone” connection, as described in APPENDIX I “INSTALLING AND USING THE
EVD4_UI PROGRAM”.
3.6.6 Start-up
After having connected the EVD4, as described in 3.5.1, connect the service serial port to a PC via the
special converter and confi gure the parameters and the address using according to the application and/
or systems used. The controller is already enabled; to switch off the EVD4, disable the Stand-alone
variable or modify the status of digital input D1 (Fig. 2.1) and run the supervisor program (i.e. PlantVisor)
to monitor the system.
