    Minimum Field resistance.

    Thanks again Mike, yes this applies to the previous post. It is a CAT generator. Being this is a standby I don't think I am too worried about PF bouncing around for the short time it'll be in service, so maybe I wont bother adding resistance. The DECS 125-15 is what we are using on all 12...

    CAT SR4B PMG Voltage?

    Bill, thanks for your input, we have discussed running it up to find the PMG voltage but this wont be possible until the engine is up and running (which may take some time). MikeL, this all sounds pretty groovy. The old generator had the 4 wire PMG with it connected in series. The new one...

    Minimum Field resistance.

    Alright lady's and gents. I've got a DECS 125-15 (automatic voltage regulator) that is looking for a minimum field resistance of 8.3 ohms. My field resistance is at 4 ohms. Anyone know if I can add a power resistor into the mix to bring up my resistance to make the DECS happy or do I have to...

    CAT SR4B PMG Voltage?

    Hello all, I've got a CAT SR4B-HV generator to install and cant find the PMG voltage anywhere. Pretty sure I need this to select the proper DECS (automatic voltage regulator) model. There are three models with three nominal inputs (60V, 120V 240V). The existing generator was an SR4 using the...
