We have installed a new ONAN genset 7.5kW MKDBJ. When trying to start it it keeps sending error 27: AC Voltage Sense Lost
Basically it runs for 2-3 seconds. When the Kubota engine
stabilizes in speed the genset shots down with this error code. The manual says: Contact Cummins - but I would still like to understand the root cause
Have any of you experienced this problem?
What is the solution?
