FAQs
Does it support AMF (Automatic Mains Failure)?
Not by itself. It is typically paired with a Master Synchronizer (e.g., MSLC) for full AMF functionality.
How is configuration performed?
Via Woodward handheld programmer or PC-based service software.
Are 5 A CTs required?
Yes. A 5 A CT secondary is required; interposing transformers are needed if using 1 A CTs.
Can it replace a 2301A system?
It provides advanced digital functionality but requires different wiring and LonWorks communication, so it is not a direct replacement.
Is this unit new?
Yes. It is 100% brand new original Woodward equipment.
