EVDRIVE is a stand-alone driver for Alco electronic expansion valves series EXM-246, EXL-246, EX4, EX5, EX6, EX7, EX8 and
EX9. The device looks in case 4 DIN modules; the user interface is made of a 4 digits custom display (with function icons) and 4 buttons (set, up, down and escape). The instrument has a TTL serial port for the parameters up-load and down-load with EVKEY. The TTL serial port (with the optional RS 485 Modbus serial interface) allows to connect the driver to the EVCO’s RICS monitoring system or to a PC for the parameter configuration with the EVCO’s software Parameter Manager. EVDRIVE 01 has also a second serial output available for the connection with other EVCo controllers. As accessory, on request it is available the battery loading module EVC99P00X7XXX00 (instrument backup function: it allows to close the EEV for blackout).
