Seakeeper 35 / 30HD Operation Manual (90269-7)
230 VAC Fluctuation, Spike, or Momentary Failure
If the AC voltage to the Motor Drive Box is outside Seakeeper’s specified range (208 – 230 VAC), the Motor Drive Box will briefly shut down for protection. The Motor Drive Box will continue operation when the voltage returns to the specified range.
A brief fluctuation can happen when the generator is unable to regulate its output voltage, particularly when a large AC load is switched on or off. A momentary AC failure also happens during transition from shore power to ship’s power.
