The problem I have with those neon lamps is they come on only when that (capacitor) stage is energized (the contactors pick up). There are instances when the electrician needs to know in advance if a fuse is blown rather than waiting for that stage to come on and then find out the fuse is blown.
I would say use ASDs. They will provide the comprehensive protection desired through out the operation.
Also wont the softstarters be bypassed into a run contactor to run the motor direct across line ?
Just my 2cents worth. Do you have some form of recording instrument that you can plug in to monitor the system? RPM and or Fluke 43b would be ideal. Leave it on for say a week and see what you get.
Thank you guys. All have provided excellent and insightful information. Now I am better equipped to provide the remote alarm that my motor starters need.
Now if I have to implement this for my capacitor banks where I only need fuse failure indication. Is there anyway to do this cheaper than...
Can anyone shed some light on how one can acheive a blown fuse detection, indication and remote notification for a three phase NEMA motor starter which has a fused disconnect as its overcurrent protection device ? I am also interested in using the same wiring for an inhouse old automatically...
