How does a fault indicator work on a power line?
Some fault indicators can block inrush current. Advanced fault indicators should monitor the live line to distinguish fault currents from usual current surges. They operate only after making sure of the feeding circuit breaker/fuse has cut the power flow and the line is de-energized.
When do line mounted fault indicators need high sensitivity?
Systems with earthing through high resistance have low phase-to-ground fault currents so require high sensitivity of FI. When there are high load currents and low earth fault levels the line mounted fault indicators should look at the differential increase of the current (di/dt) instead of the absolute value.
Are there any problems with the slide out?
Most slide out problems are not that difficult to trace and then solve. There will be those that require the help of a professional technician to repair. The key would be to get to know your system and learn when the task is beyond your abilities to handle .
How are fault indicators used in isolated ground systems?
Ground fault indicators for isolated ground systems sense the vector sum of the current and look for an imbalance indicating a fault on one or more of the three phases. Systems with earthing through high resistance have low phase-to-ground fault currents so require high sensitivity of FI.
Is there an electrical problem with the slide out?
Finding an apparent electrical button, the control panel was removed and the wires for the stuck slide were placed on another slide “in/out” button. Again, there was no power to the stuck slide when the “In” was pushed. The two young mobile repair techs were now perplexed and did not have the skill to trouble-shoot the electrical issue.
How to troubleshoot the Lippert electric slideout system?
TROUBLESHOOTING The Lippert Electric Slideout Systemis only one of four interrelated slideout room system components. These four components are: chassis, room, coach, and Lippert Electric Slideout System. Each one needs to function correctly with the others or misalignment problems will occur.
Why is my slide out motor not working?
RV Slide Motor not Working. The bad news is that one of your slide out motors may have died. The good news is that the failure is due to a faulty wire or connection which caused a short and tripped a breaker. The latter may not be the case if you have 2 motors on your slide out and one is still working.
What kind of wires are in a slide out motor?
All that I saw were the green and yellow wires coming out of the wire bundle that connected to the motor’s black and red wires (see the motor photo above).
