Default 300-2373 overvoltage undervoltage module

A new guy, looking to draw on experience here.

I'm looking for someone that knows this control & the equipment this is installed.
My guess is a transfer switch. My intention is to use it to protect my service from a Kohler 30r with known over voltage issues. The wiring diagram of the equipment this is installed would tell me all I need to know.


Thanks Jim

That is out of an OT II control box. Onan transfer switch. I have a print but I don't think it would do any good. A few more items go with it.

What is wrong with the Kohler. They are pretty reliable units.

Its a voltage sense module for an OT II transfer switch. Not meant to be a stand-alone component.

PM me with an email address and I'll see what I can get you.

There are better options on the market, made to be wired directly to that would serve your purpose. These cards are going the way of the dinosaur and getting harder to find.

I figured it was used to control a relay or 2.

Photo transistor board shorted & put full power to SCR pack, 377 volt output
with no overvolt protection, has overspeed & low volt. Tore it down ohmed & meged OK, ordered board kit.

I picked it up cheep, after the owner tried to use it last month & blew up all kinds of stuff. He did not run it for a year or so. You can't leave equipment sit down here, leave it sit turns to s***!

For the record M# 30ROZJ01 S# 354567 no spec # on tag, engine has 1994 on valve cover. Enough hours on it to breakin engine.

Depending on which controller your generator has Kohler offered an overvoltage shutdown module. Or a better alternative in a stand alone module for overvoltage only might be a TimeMark AC160B or similar (maybe a B269 if wired 3 phase), these can often be found used on ebay for $20-30.

Jim biggest problem I have seen with that model Kohler. Over here in Texas. Is mice love the wire insulation. I used to get 4-5 a year with chewed up wires. Must have sugar in the wires.

Saw some farmer's twine (small rope) with metal wire wrapped arround it ( electric fence). I handled it felt and smelled funny. Had something bitter in it. Farm store might have some of that chemical to put on gens to stop mice chewing wires.
