EVDR-0201 A Controller

DIAGNOSTIC FEATURES:
  •   Any supply voltage below 8.5 Vdc
    causes the controller to default to
    the valve-off mode.
  •   The driver output drops and holds
    at the inactive stand-by condition.
    Any short or open circuit condition is automatically detected as an error.
  •   When the fault is corrected, the
    controller returns to standard
    operation.
MULTIPLE PERSONALITIES
The EVDR controller is available in multiple configurations (personalities) to suit the
needs of specialized applications.
Visit www.Hydraforce.com and choose the one that best fits your needs. All are configured
with HF-Impulse software.

EVDR-0201A - General Purpose
EFDR-0201A - Fan Drive Applications
DESCRIPTION
A compact plug-in style, microprocessor based, valve driver designed for use in hydraulic
proportional valve applications. Configurable to drive either one or two coils using SAE J1939 CAN
input or an independent signal. The EVDR-0201A proportionally controls one or two coils to a
user-defined metering profile. The profile provides either a straight-line or multi-sloped output that
you configure with HF-Impulse software: an easy to use, web-accessibile configuration tool available
as a free download at www.hydraforce.com/electronics. Two output LEDs are located on the front
- see Dimensions and Mounting.

OPERATION
The controller accepts inputs from commonly available analog or J1939 CAN operator interface
devices (joystick, potentiometer, sensors, etc.). The input signal drives the output current to the
user-defined ramp rate, enabling accurate and proportional metering of the hydraulic valve. As
the input changes, the output follows the defined metering profile, allowing optimum system
response. You can configure the unit for direct valve operation. Built-in diagnostics detect fault
conditions that automatically deactivate the outputs. The controller has two LED output indicators.
