Compared to the standard EVD drivers, these devices feature advanced functions and a new user interface that makes them even easier to use and configure. A new graphic display and a simple programming procedure mean the controller can be started after selecting just four parameters and just three if using the device to control Carel valves : refrigerant, valve mode, type of pressure probe and type of application chiller, display case, etc. Main functions: superheat control with high pressure, low pressure and low superheat protection assisted start-up procedure selecting just 4 parameters connection diagram shown on the display removable graphic LCD, multi-language interface with online help for the parameters and SI or imperial units of measure user management with password to access different configuration levels copy parameter values to different EVD devices from the display LEDs for monitoring the main parameters use of low-power ratiometric pressure transducers with 4 to 20 mA output these can be shared between several drivers second digital input for defrost management possibility to use backup probes Combined with CAREL ExV series electronic expansion valves, the EVD Evolution drivers make up an integrated control system that optimises evaporator operation and obtains high energy savings.
