levels according to requirements.
Product Usage Instructions
- Single Coil EDC Control: Use a Double Pole, Double Throw (DPDT) switch for changing direction.
- Dual Coil EDC Control: Use a Single Pole, Double Throw (SPDT) switch for changing direction. One coil of a dual coil can be wired and switched accordingly.
- Multiple EDCs Control: When controlling two or three EDCs, wire the coils in series or EDCs in parallel as shown in the provided wiring diagram using a DPDT switch for changing flow direction.
Frequently Asked Questions (FAQ)
Q: What is the purpose of the trim pots on the amplifier?
A: The trim pots allow users to adjust the output levels based on the
position of the foot pedal for customized control.
Q: How can I control multiple EDCs using the amplifier?
A: Refer to the provided wiring diagrams for instructions on wiring
multiple EDCs and using a DPDT switch for changing flow direction.

GENERAL DESCRIPTION
This amplifier is designed to work with the Danfoss foot pedal (KEP). A typical application would be controlling a variable-volume piston pump that is fitted with an Electrical Displacement Control (EDC). Trim pots on the amplifier allow the output levels to be tailored with respect to foot pedal position. An enclosure protects the internal circuit board and provides a means of mounting. The control has (3) LEDs to indicate +12 V power, +8 V regulator and output current.

ADJUSTMENTS
TYPICAL WIRING CONNECTIONS
Controlling a Single Coil EDC Requires a Double Pole, Double Throw (DPDT) Switch for Changing Direction.
Controlling a Dual Coil EDC Requires a Single Pole, Double Throw (SPDT) Switch for Changing Direction. Also, Just One Coil of a Dual Coil can be Wired and Switched as in Above Diagram.
When Controlling Two or Three EDCs, They must be Wired Coils in Series/EDCs in Parallel as Shown in Diagram Below. A Double Pole, Double Throw (DPDT) Switch is Used for Changing Flow Direction of the PV.
