I have a VFD (AB Power Flex 70) operating a 5 hp motor controlling a progressive cavity pump pumping starch material. The system is set up to pump the material for a time then flush for a time after material is used from tank system cycles again to fill the storage tank. This system has been...
I have used several types of Sensors to detect Sheet Break on Paper Machines without problems, both reflex and diffuse relective, also thru beam. I am wanting to install a sheet break device near a Coater where coating that gets applied to the paper surface. The Coater currently has a...
I have a 40hp DC Motor on a Digital Drive and I would like alarm maybe with a flashing light, not shutdown if the Motor Blower is not operating. This Drive is stand alone not connected to PLC or DCS. The Motor Thermal Switch is going back to the Drive but I would like to catch the problem...
I have a Line Tamer CLT 5000 GTW Transformer with 120v in and 120 out feeding a Panel for several instrumentation devices. This unit is rated for 29 amps and is pulling 8 amps when measured, nothing on the load side has changed in over a year. It was noticed making a very loud humming noise...
Any thoughts or direction on this would be appreciated.
The plant where I work we have had a GE 228X275 on a Ground Fault Relay in a 2300v Full Voltage Induction Motor Starter trip when the motor stop switch was pushed, routine way it is stop. This has happen twice, I did not see it I was told...
I have read Armature Current with a Clamp On Amp Meter many times on AC and DC Motors. However on DC Motors I have generally read a lead to see if it looked normal. Recently I had a 7.5hp DC Motor that seemed hot when I shot it with a Pyro, 167 F. I then checked the Armature leads at the Drive...
I need to install a flow switch to detect Seal Water to interlock the starting of a 2300v motor. Does anyone know of a product that they may have used in a simliar application?

I am just starting to use VFD's, I have a learning curve. I have an application where I recently installed a small VFD and 1 HP Inverter Duty Motor on a pump. The pump we had in spares and is used to move liquid. The rate Operations needs it to flow came out to be about 1000cc but to get this...
This will be a simple question for you guys on here.
I have a vent fan that is controled by a GE 30HP 480 v Frame 286T motor using a magnetic starter. I was considering slowing the speed of the fan down because too much air is moving in the room. I have a unused Allen Bradley VFD that is rated...
AB Power Flex 70 VFD Digital In Parameter. 361-366 Parameters are set up for Digital In's with values of 0-46. I am using value 4 "Aux Fault" to sense a motor thermal overload and fault the drive. I have an empty parameter and would like to fault the drive from another device. Does anyone...
I am rebuilding a 2400vac Induction Motor Starter. It all seems to work except for the Watt Transducer. I am using 2 CT's and a PT. The Watt Transducer has negative output or low positive when moving CT and PT wires around trying to troubleshoot. The CT's are bar type and bought new without...
Where I am working they want to rebuild a Full Voltage non Reverse 2300v induction Motor Starter. I have not worked much with medium voltage starters and I am asking for assistance. We have several older 2300v Induction motor starters that have had the motors and equipment removed. I am going...
