EFDR-0201 A Controller

 

DIAGNOSTIC FEATURES:
  •   Any input below 8.5 Vdc causes the controller to default to safe mode of
    "valve off."
  •   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 on hydraulic proportional valves for fan drive applications. Configurable to drive two coils using SAE J1939 CAN input or an independent signal. The EFDR-0201A proportionally controls one coil to a user-defined metering profile and provides reverse sequence control with the second coil providing fan direction. The profile provides either a straight-line or multi-sloped output that you configure with HF-Impulse software: an easy to use, 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 sensors or SAE J1939 CAN input. The input signal drives the output current to the user-defined ramp rate, enabling accurate control of fan speed. Reverse sequence control is provided as well. The reverse sequence changes the direction of the fan to clear debris. A variety of methods can trigger the sequence (switch input, temperature sensor, J1939 message or periodic.) The timing sequence can control the fan speed as well as the fan direction to avoid abrupt reversals. Built-in diagnostics detect fault conditions that automatically deactivate the outputs. The controller has two LED output indicators.
