Application-Specific FAQ
Q: Which ATOS proportional valves is the E-ME-AC-01F compatible with?
A: The E-ME-AC-01F is designed for ATOS proportional directional control valves and proportional pressure/flow valves that require an external amplifier card. Always verify coil resistance and current rating against the amplifier output specification before installation.
Q: Can this amplifier be controlled by a standard PLC analog output?
A: Yes. The unit accepts a ±10 V DC command signal, which is standard on most Siemens, Allen-Bradley, Mitsubishi, and Omron PLC analog output modules.
Q: Is the dither frequency factory-set or field-adjustable?
A: The dither frequency and amplitude are field-adjustable via onboard potentiometers, allowing optimization for the specific valve and hydraulic fluid viscosity in your application.
Q: What happens if the enable signal is removed?
A: The amplifier output current drops to zero, de-energizing the valve solenoid and returning the valve to its spring-centered or fail-safe position — compatible with standard PLC E-stop and safety relay circuits.
Q: Do you provide technical support for commissioning?
A: Yes. Konmask.com provides pre-sales application support and commissioning guidance. Contact our team with your system schematic for tailored advice.
