Looking at the data sheet on the input modules, looks like input voltage goes to pins 1 & 2 like the coil if you will, pin 3 gets +5vdc, pin 5 get...

The outputs are opposite. You need to give it 5vdc for coil voltage and run 120vac through the contact to your Indicator on the AC modules. Use 24 vdc...

It may be a poor design but it is the design of 90% of the hydros without softstarts we have on service.

I've never looked for AC ripple on a tach. Would this be from poor commutation or induced voltage from something else?

I would definitely rule out any mechanical binds first on that one. Bearings, safeties hung up, etc.

Ya I've never seen a socket for them exactly. You may have to cannibalize a PMI card, they used individual pin sockets set into the circuit board. Wit...

I have used a Streamlight Strion for 5 years now, I think it is perfect. I also bought the HL version but found it too be too bright and the battery w...

I had this happen once too from welded starter contacts. I can think of very few manufacturers that used a line contactor excluding Montgomery's P con...

Sorry, I didn't mean to advertise Thyssen's tester on your post. I'm sure it's rediculously overpriced anyway.What about PMI modules? Or the miniature...

The part # 9852109. And correction: It has alligator clips not Mini Grabbers. Relay Tester

No idea of the cost but you just grab P24 G24 with Mini-Grabbers from the controller. I'll post the part #.

Well in my laptop bag anyway.Thyssen does sell a little tester for the 24 volt relays only. It has one blue Finder base and one black Schrack base.
