I use the Arduino with ethernet shield to log data, then send it along to a server on querying the embedded web server.

CEC provides for increasing the setting of an inverse time breaker for hard starts, but is silent on such an allowance for instantaneous breakers.

yes it is industry standards to monitor the aux contacts, and break your latch logic accordingly.

sounds like a possible solution is an embedded micro, depending on your I/O drive requirements

for hydraulic top drives we'd stack 6 pumps behind a 1200hp diesel. Watch your ability to dissipate the heat.

the fluid with the least energy gravitates down. Only when their energy levels increase would they rise.

looking at investing into a shrink sleeve portable printing system. Can anyone reflect on their experiences. Application is largely control / PLC wiring.

I reread and see it's DC running alongside. You should have no problem as the most basic filtering will likely suffice.

500' feet is a long parallel run. Your looking for trouble. However, your translation to output can be effectively filtered with many controllers. Mind code as cables within a conduit must not be from seperate sources.

Nice overview, thanks. would not all protocols improve in a TC/IP wrapper?

CNC, yes, manual, not likely. What normal?

Static rings need a complete coating to allow them to conform in thier glands. Dynamic rings as well, but in addition, lubricant throughout thier travel. This may mean a resivoir of some fashion. On the other side, excessive lubricant may be problematic. Condiser the operational requirements of...

absolutely. In that case it's multiple motors on a single O/C, each requiring O/L.

I'm digging deeper into this PLC thing and reading about various serial busses. DeviceNet, ControlNet, /IP. Which is leading the way and which has better performance under remote I/O connections. Anyone offer a generalization where one exceeds over the other.

what does your error history report?

the primary reason is distance from source, and the potential voltage drops induced. When you are the source, you have much less influence on voltage regulation, as your 'hands are on the controls' sort of speak. Local high drawing consumers can signal starts with part winding schemes, or co...

The CEC accepts O/L rated VFDs as full filling the requirement for overloads. They do not speak to VFDs as having any influence on overcurrent, and one handles it as either a motor, transformer, or demand load. Motors being 250% FLA max for breakers. VFDs are not considered acceptable for...

go with waross. An auto is much smaller than an isolation of the same kva rating.

with such inertia, you likely have an extended start. If, as suggested, your starting part winding with softstart in open Delta, you'll hammer the one winding until your up to speed, hence the absolute requirement for O/L on both windings. I'd be looking at shortening your start ramp as much as...
