    First start of a MEP-002, do's and don'ts?

    Get a good look at the motor mounts too. Sent from my SM-G973U using Tapatalk

    First start of a MEP-002, do's and don'ts?

    Biggest thing is never idle them, That is what kills the regulators

    Mep 002a battery charging

    Start by checking the fuse. If you look in the tm theres a procedure to test the battery charging alternator Sent from my SM-G973U using Tapatalk

    Making stationary engines more efficient when loads are reduced

    You're welcome, Once they are setup its pretty much pushbutton start. To be fair the same thing can be done with a vfd, it just takes some more setup. Sent from my SM-G973U using Tapatalk

    Making stationary engines more efficient when loads are reduced

    A vfd (variable frequency drive) takes ac inverts it to dc than through a set of transistors created a pulse width modulated synthetic ac output at a user specified frequency. This allows motors to be started slowly and run at different speeds. A soft start is basically a smaller dumber...

    Making stationary engines more efficient when loads are reduced

    The last time I had to look into it (approx 2 years ago) it was cheaper to soft start. But you never know you might get the deal of a lifetime. You also have to make sure the motor is rated to operate with a vfd, some of them dont work well with the carrier frequency (burnt windings is a smell...

    Making stationary engines more efficient when loads are reduced

    If you are not changing the electric motor speed you are better off using a soft start vs vfd. Sent from my SM-G973U using Tapatalk

    Generator Hook up 1 phase zig zag or double delta

    In the above example 1 is line 1 6/4 is neutral 2 is line 2. 3/5 is a winding interconnect. So 1 to 2 is 240 volt. 2 to 6/4 is 120 and 1 to 6/4 is 120. Keep in mind this is an oversimplified explanation of how the physics work. In practical application there is a bit more to it (since its a...

    genset loadbanks

    The one i built has run for 4+ hours at a time. There is enough air flow to prevent damage. I attached all 3 tubes to a steel plate then attached that to an airhandler blower. Ill try to get you some photos if you need them. Sent from my SM-G973U using Tapatalk

    genset loadbanks

    Depends on the fans they use. If the fans use a 3 phase motor it wont work. I used a fan and some dryer heater elements (got 3 for 120) they are 5500 watt each and can be wired into thirds (they are essentially wye tapped) Sent from my SM-G973U using Tapatalk

    Generator purchase advice

    I used a generac 200 amp service rated transfer switch. Generator side I have 2 relay boards one is outputs to the generator the other is inputs back to my plc. I figured out what the contacts on the switches are doing at each step of the starting process and paralleled them. I replaced the...

    Generator purchase advice

    I used an automatic transfer switch. I completely automated the generator and transfer switch. You can use a double throw safety switch and indicator light on the utility side fairly easily Sent from my SM-G973U using Tapatalk

    Generator purchase advice

    The 004 and 005 can be converted to single phase. Sent from my SM-G973U using Tapatalk

    Generator purchase advice

    If it helps with the single phase mod I can run my 004 at 72 amps. Sent from my SM-G973U using Tapatalk

    Weak air intake on an MEP-803A

    Disclaimer: I have never touched this model, nor do I claim expertise on it. That being said, my best guess stuck/improperly seated valve/improper lash. I cant imagine checking valves being that difficult. Sent from my SM-G973U using Tapatalk

    Consequences of Failed Interlock – When the Grid Feeds Your (out-of-sync) Generator

    Interlocks have a very special place with me, I have some friends that never went home because of them.

    Consequences of Failed Interlock – When the Grid Feeds Your (out-of-sync) Generator

    Definitely a thing to watch. We had one at a water plant (wasnt syncing utility was 2 paralleled sets) and the operator misread the syncroscope. Tldr one gen set jumped off its pad. Sent from my SM-G973U using Tapatalk

    All you really need is 24 volt momentarily on the field to start the process. I cant recall what the factory flash is. Sent from my SM-G973U using Tapatalk

    MEP-004a

    At a glance I question the rating of your regulator, its spec sheet indicates that it is for a field of 15 ohms minimum, your field is 2 to 4 ohms. It might be too small. I did something similar with a 005, and needed to parallel 2 regulators to keep the field up. Sent from my SM-G973U using...
