DIAGNOSTIC LEDS
It is possible to use two E-MI-AS drivers to operate one double solenoid proportional valve supplying the same analog signal to both CMD1 inputs referen-
ce. The enable input signal is used to select which driver/solenoid has to be active.
To operate double solenoid valves it is required to:
- parallel wire the two drivers (see following scheme).
- select opposite polarity (default and reverse) for the two enable signals (see 4.5)
- manage from PLC or machine unit: 1 analog reference signal corresponding to desired valve’s regulation and 1 ON/OFF signal to select the active
solenoid.
