4.5. XEV20D Hardware Overview
The XEV20D is a stepper valve actuator is intended for either
bipolar stepper valves or unipolar stepper valves. This device is
used in combination with the iPro Case Controller to drive the
electronic expansion valves and electric evaporator pressure
regulator in the refrigerated case or walk in box. Each XEV20D
drives two (2) valves and the iPro Case Controller system
supports a maximum of two (2) XEV20D per iPro. The XEV20D
communicates with the iPro Case Controller via the CAN Bus
port on both devices. When driving stepper valves with this
actuator, check the valve manufacturer technical specifications
for the current ratings and verify if the XEV20D can drive the
valve selected for the system.
The XEV20D driver has onboard LED lights that show device status and the valves being controlled. See
Table 4-5
below for LED
function descriptions.
