A 200hp across the line on the same transformer is your brownout. Six times FLA for a second or two, the transformer sags, the DC bus on the drives dr...
120 ohm across the 1400 terminals, bias jumper on. Swapped + and minus on 4 and 5 after checking which side sat high with the meter. 4 and 5 read now....
Soft starter it is, 45kW with the bypass, pressure switch stays as it was. Started it this morning with a clamp on the motor lead, door open, gloves a...
Warmer copper, more loss. Or just day shift. Either way it's fixed.
Continuity isn't the test. A fuse can read zero ohms on a meter and still have half its element gone. High resistance under 90 A drops volts, and it's...
What's on the relay sockets? Any little module clipped across the coil terminals, a diode, an RC? And the coils are DC, not AC through a rectifier?
Did the kWh carry like Scott said, REAL sub total into a DINT kWh, and seeded the DINT from the meter's own register so the report doesn't start from ...
A to B idle at meter 6, 0.02 V. Nothing there. At the panel end it's 0.2 V. Meters 4 and 5 are a newer batch, terminals say + and minus instead of A a...
Pressure switch and the unload solenoid, that's the whole controller. There's nothing on it that could take a speed reference, and the compressor vend...
DINT, says so in the tag list. Historian has 2,147,480,112 at 05:58 and then -2,147,428,851 at 05:59. The meter's own kWh reads 2,148,900 since it was...
Meter it before you guess. Network power off, ohms between CAN_H and CAN_L at the scanner tap.
