1INTRODUCTION
1.1 Introduction
The drivers of the EVDRIVE06 series are devices studied for the management of bipolar stepper electronic expansion
valves.
They are available in built-in and blind version (according to the model).
The user interface of the built-in versions consists of a LCD graphic display, of six buttons and guarantees an index of
protection IP40.
The blind versions must be used with a remote user interface.
They can be powered both in alternating and in direct current (24 VAC/DC).
The drivers can work with the most common temperature probes (NTC and Pt 1000) and with the most common
pressure transducers (0-20 mA, 4-20 mA, 0-5 V ratiometric and 0-10 V).
They have configurable digital inputs (enable the operation, change parameters set, backup module status, etc.) and a
5 res. A @ 250 VAC digital output (electromechanical relay) configurable as alarm output, solenoid valve or
resynchronization valve.
Through the USB port it is possible to make the upload and the download of the configuration parameters (using a
common USB flash drive); through this port (or the RS-485 one), it is also possible to connect the devices to the set-
up software system Parameters Manager (through a serial interface).
Through the CAN communication port (or the RS-485 one) it is possible to connect the devices to a controller or to a
remote user interface instead.
Through the backup module EPS4B it is finally possible to close the valve in case of lack of power supply of the drivers.
Installation is on DIN rail.
Among the several functions one highlights the possibility to work both in stand alone mode and under the supervision
of a controller, the management both of generic electronic expansion valves and of the most common valves Sporlan,
Alco, Danfoss, Sanhua, Castel and the management of the backup probes.
