Frequently Asked Questions (FAQ)

1. What type of signal does the 8290-180 output?
   It outputs a 0–5 VDC analog signal proportional to the real-time generator load.

2. Can this sensor be used in multi-generator systems?
   Yes, it is specifically designed for load sharing and parallel operation systems.

3. Is galvanic isolation included?
   Yes, input and output circuits are fully isolated for safety and signal integrity.

4. What kind of input connections are required?
   The unit accepts voltage from potential transformers (PTs) and current from current transformers (CTs).

5. Is it suitable for marine environments?
   Yes, provided it’s installed in a protected, dry cabinet with controlled ventilation.

6. How is the sensor mounted?
   It can be mounted on a panel or DIN rail, depending on the system layout.

7. Does it require regular calibration?
   Minimal calibration is required after installation; periodic checks are recommended for critical applications.

8. Is it compatible with non-Woodward controllers?
   Yes, as long as the controller accepts 0–5 VDC analog input, it can be used.

9. What protections are built-in?
   It includes internal fusing, isolation, and overload protections for both voltage and current inputs.

10. Can it be used in solar-diesel hybrid systems?
    Absolutely. It provides essential load feedback for hybrid energy management systems.
