| 203 | Voltage matching: For Decs 100 and 200the ratio of the sensingVTs for generator and busbar voltage can be different. The customer must ensure the heat transfer out of the machinery room. Alternator is designed for inclinations of: 5°/7,5° Fore-and-Aft & 15°/22,5° Athwartships (stat./dyn.). The altenatorshaft will be installed in parallel to the ships centerline. Please contact the factory if alternator shouldbe installed in athwarts direction. Cross Current Compensation (CCC): It must be ensured thatCCC is de-activated when the mode of regulation is changed from"AVR-mode" into "PF/VAR-mode". | ||||
