Application-Specific FAQ
Q: Is the WOODWARD 9907-164 compatible with my existing EG-3P actuator?
A: Yes. The 9907-164 is designed to drive WOODWARD EG-series proportional actuators. Verify the actuator coil resistance and current range against the governor’s output specification in the datasheet.
Q: Can this governor be used for parallel generator operation?
A: Yes, with the appropriate load sharing accessory. The 9907-164 supports droop mode and can be configured for isochronous load sharing when connected via WOODWARD’s load sharing lines.
Q: What is the difference between the 9907-164 and the 9907-165?
A: The suffix variants typically differ in input voltage range or output current rating. Always confirm the exact part number against your system’s power supply and actuator specifications before ordering.
Q: Do you provide technical support for commissioning?
A: Konmask provides pre-sales technical consultation to help confirm compatibility. For on-site commissioning support, we recommend engaging a certified WOODWARD service partner.
