FAQ
FAQ
Q1: What is the Woodward 8290-189 used for?
A: The 8290-189 is an EPG electrically powered governor used for isochronous speed control of diesel engines. It regulates engine speed by controlling a compatible electric actuator.
Q2: What power supply does the 8290-189 require?
A: The 8290-189 is designed for a 24 VDC battery system. Woodward’s product documentation identifies it specifically as the 24 V diesel version.
Q3: What is the required speed input frequency?
A: The specified speed range for the 8290-189 is 3,000 to 6,000 Hz. The speed signal is normally provided by a magnetic pickup monitoring the prime mover.
Q4: Does the 8290-189 have a start fuel limit?
A: No. The 8290-189 is the 24 V diesel version without a start fuel limit. Woodward lists it separately from the 8290-184, which is the corresponding diesel version with a start fuel limit.
Q5: Which actuators are compatible with the 8290-189?
A: The EPG system can be paired with Woodward 524 or 1724 series actuators. The actuator provides the mechanical movement required for fuel-control positioning.
Q6: Is the 8290-189 suitable for generator applications?
A: Yes. The EPG system can control prime movers driving generator loads. For generator sets operating in parallel, additional switchgear and appropriate load-sharing equipment may be required.
Q7: Is the Woodward 8290-189 still in production?
A: The 8290-189 is generally treated as a legacy/discontinued Woodward model. Replacement, surplus and repair-market availability can still be found. QCC’s current product information continues to list 8290-189 as an EPG controller part number.
Q8: What are the dimensions and weight of the Woodward 8290-189?
A: Available supplier information lists the unit at approximately 150 × 100 × 50 mm and 0.86 kg (1.90 lb). Because published dimensional information varies between suppliers, the actual unit and nameplate should be checked when exact packing or cabinet-space calculations are required.
