Actuator loop feedback response directly determines dynamic governing stability, maintaining steady-state shaft positions within +\/-0.25 percent under load variations. High ambient operational capability up to +93 deg C relies on natural conduction through mounting points, demanding uniform thermal heat sink dissipation across the engine frame or skid mounting interface to prevent heat accumulation during maximum work output conditions (2.3 J).\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eQ: What sizing criteria apply to the power source supplying this actuator?\u003c\/li\u003e\n\u003cli\u003eA: The auxiliary battery charger or power unit must supply a continuous current of at least 5 A when energized, backed by a 10 A slow-blow fuse or dedicated circuit breaker installed on the non-grounded battery lead.\u003c\/li\u003e\n\u003cli\u003eQ: What is the signal threshold required from the magnetic pickup sensor?\u003c\/li\u003e\n\u003cli\u003eA: The system requires a minimum signal of 1.5 Vrms generated during engine cranking, typically occurring at a minimum frequency of 100 Hz, to establish a stable speed control feedback loop.\u003c\/li\u003e\n\u003cli\u003eQ: What input component modifies the idle speed setting?\u003c\/li\u003e\n\u003cli\u003eA: Idle speed adjustments between 25 percent and 100 percent of the rated operational speed are set using an externally connected 50 kohm potentiometer interface.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVerify that the physical mounting surface acts as an adequate thermal heat sink, ensuring operating temperatures remain below +93 deg C under full electrical load.\u003c\/li\u003e\n\u003cli\u003eInstall a 10 A slow-blow fuse or equivalent circuit protection device directly into the positive (non-grounded) DC supply line prior to energizing the actuator.\u003c\/li\u003e\n\u003cli\u003eEnsure output shaft linkage connects without mechanical binding or excessive radial slop to preserve transient governor response characteristics.\u003c\/li\u003e\n\u003cli\u003eGround all control wiring shielding at a single point to prevent ground loops from degrading magnetic pickup signal accuracy.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Woodward","offers":[{"title":"Default Title","offer_id":50738328633596,"sku":"8256-016","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/8256-016.jpg?v=1785376955","url":"https:\/\/www.electronicplc.com\/ar\/products\/woodward-8256-016-electrically-powered-governor-actuator","provider":"Electronic PLC","version":"1.0","type":"link"}
