Woodward 9907-838 Load Sharing Module

FAQ

Q1: What is the primary function of the load sharing module?
A1: It allows multiple generator sets to share load while operating in parallel, in either isochronous or droop mode.

Q2: What supply voltage is required?
A2: DC supply of 18–32 V.

Q3: What input signals are required from the generator?
A3: 3-phase PT inputs rated 95–130 V AC and CT inputs for load sensing.

Q4: What is the output signal to the speed control?
A4: +0.5 to +4.5 V DC analog signal for adjusting engine speed for load sharing.

Q5: In what environmental conditions can this module operate?
A5: Operating temperature –40 °C to +70 °C, shock resistance 40 g, 11 ms sawtooth.

Q6: What are the module’s dimensions and weight?
A6: Dimensions 273.6 × 59.2 × 214.1 mm, weight 1.36 kg.

Q7: What is the difference between isochronous and droop modes?
A7:

• Isochronous mode: All generators share load while maintaining constant speed/frequency.

• Droop mode: Generator speed drops as load increases, used for parallel operation without a master speed reference.

Q8: What precautions are required during installation?
A8: Ensure correct CT/PT phasing, proper grounding of shielded cables, cable lengths ≤ 30 m, and do not disconnect CTs while energized.
