FAQ

What is the "EPC" in EPC Amplifier?

EPC stands for Electronic Proportional Control. This amplifier is designed to provide a precise, variable current output to control proportional hydraulic valves, allowing for fine control over flow or pressure.

The label indicates a "Factory Setup", suggesting that key parameters are pre-configured. While some adjustments might be possible via the COM port (likely RS232 or similar), extensive reconfiguration may require specialized software from Oilgear. Always consult the technical manual before making changes.

The 'Run/Fault' LED provides the general operational status of the amplifier; green for normal operation and red for an internal or external fault. The 'Valve' LED typically indicates the status of the output to the valve coil, confirming that a signal is being sent.
