ONAN

I have a 2007 Itasca Impulse 24V with a 4 K Onan generator. It takes about 2 minutes before electric comes on. Is that normal. Do I have a transfer switch that has the delay built in?? TIA

A Progressive Industries EMS has a 136 second (2 min, 16 sec) delay between application of power to the input, and switching the outlet on. Do you have one of those in the system?

If you have an Power Control System (PCS) installed, it will also delay the use of generator power for about two minutes.

For what it’s worth, our little 2800W in the Travato takes every bit of 2 minutes before it allows load to go on it.

The transfer switch should have a delay built into it to allow the generator to warm up and stabilize before switching the load to it.


Without that it would be very common for a generator to read an over/under speed fault or voltage issue and shut itself down immediately upon start up due to having a load put on it before it was running in a stable manner.

Equally important to not add a load when starting the generator for a few minutes, is disconnecting any load before shutting it down...

These are pretty standard instructions for use of generators, whether they are in RV, home setups or industry. We don't treat our RV sets very well but still expect them to last. All the wiring should be given time to cool at the end of the run I but I don't know of anybody who consistently does it.

A lot of people don't consider that running a generator an hour is about the equivalent of riding a small air cooled motorcycle down the highway for an hour. Running a generator for an hour is about the same as driving 60 miles, 5 hours - 300 miles while 50 hours would equal 3,000 miles. You'd change the oil in an air cooled motorcycle every 3,000 miles yet how many run their RV generators more than 100 hours which is the equivalent of over 6,000 miles between oil changes?

Good point. I guess Oman’s suggested oil change interval is a worse case scenario...
