More Information

Overview Manuals Speed Input Actuator Output Droop Control Product Applications

Features:

  • Engine-governing role: The 701A controller regulates reciprocating-engine speed through a closed control loop.
  • Pickup-to-actuator path: Magnetic-pickup speed feedback is converted into an actuator command.
  • Operating flexibility: Isochronous, droop, and remote speed-reference functions support different governing tasks.
8280-192 is the Woodward 701A catalog configuration that links measured engine speed with an electronic actuator command. Its purpose is to keep the driven machine near the requested operating speed as load changes.

The controller sits between the rotating-speed pickup and the fuel or energy actuator. It interprets the speed signal, compares it with the selected reference, and adjusts the actuator through the governing loop.

Product selection must follow the actual engine-governor arrangement rather than the 701A family name alone. The pickup, actuator, power system, and intended control mode define the installation represented by this catalog.

Apter Power can help review official documentation for 8280-192, coordinate quotation, and support catalog-specific sourcing.

Description
8280-192 is the Woodward 701A configuration with magnetic-pickup speed input, low-voltage DC power, and a 0-200 mA actuator output. Official model-selection data identifies catalog 8280-192 for reciprocating-engine speed control duties.

8280-192 supports isochronous or droop operation and accepts a remote speed command. Commissioning should verify MPU frequency and signal level, actuator current direction and range, 18-40 V DC supply, speed set points, dynamics, overspeed protection, and the driven-machine procedure.

Technical notes
8280-192 must be configured for the installed engine, magnetic pickup, gear tooth count, and 0-200 mA actuator. Verify 18-40 V DC power, MPU frequency and amplitude, actuator polarity, remote-speed input, droop settings, dynamics, and independent overspeed protection. Perform commissioning under the engine manufacturer's approved start and load procedure.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can an engine using 8280-192 fail to reach stable speed during cranking?
The magnetic-pickup signal must be usable within the documented 60 to 15000 Hz input range. Check MPU gap, amplitude, polarity, and actual gear-tooth count before tuning the governor.
Can 8280-192 drive an actuator that requires more than 200 mA?
No. This catalog provides a 0-200 mA actuator output, so an actuator outside that current requirement needs a different approved control arrangement.
When should droop mode be selected instead of isochronous control on 8280-192?
Select droop only when the generator or mechanical-drive load-sharing design requires it. Prove the intended sharing behavior before connecting the unit to a common load.
How should the remote speed reference be checked while commissioning 8280-192?
Apply a known 4-20 mA command and verify the expected speed response with the engine unloaded or under the approved test condition. Stop if scaling or direction is incorrect.
Which protection must remain independent of 8280-192?
Maintain the engine's independent overspeed protection. Governor speed control is not a substitute for a separate shutdown path, so prove that protection before operational testing.
Before replacing 8280-192, what tuning information should be retained?
Keep the MPU gear data, actuator direction and current, supply arrangement, speed references, droop/isochronous choice, and proven dynamic settings. Recommission from that baseline rather than copying an unrelated engine setup.
