![]() ![]() This should determine if the sensor is responding to noise generated by the fan assembly. Proceed to test the fan and sensor for normal operation and see of the interfering symptom still exists. If you do not have a long one with a length of 50 to 100 feet (up to 30 meters) you may have to borrow one or purchase one.Ĭonnect the extension cord to the pigtail and route the extension cord off into the house and plug into another power outlet that is known to be on a separate circuit. The next step is to utilize a long extension cord. Possibly a slightly longer screw will be required). (Note it may require some finesse to route the core correctly so the sensor can be re-mounted without pinching the cord. Not replace the sensor back on its normal mounting but let the pigtail cord hang out of the electrical box and down the wall. Use care to make sure that the pigtail cord and the sensor power are NOT connected to any part of the existing in wall wiring. This pig tail would be a part of cheap extension cord that had been cut in half and use the end that has the male plug remaining. ![]() Then wire the sensor to a short pig tail piece of cord that is one to two feet in length (0.5 meter). Then temporarily disconnect the sensor from the supply wires in the box and cap off those wires. You could run an experiment by opening the electrical box for the motion sensor. Here is some guidance to help you isolate whether the problem is electrical in nature. It just has to do that well enough so that the motion sensor isn't falsely triggered. The cap will "take the edge off" the spike, so to speak. But a voltage spike looks like high frequency content which passes through the cap. The small capacitance of the surge cap appears to be nearly an open circuit to 60 Hz power line AC (a very high impedance). Peter worked with Deadpool actor Ed Skrein, X-Men: Apocalypse actress Sophie Turner. beyond the line voltage) so it can take the spike. Peter Dinklage portrayed Bolivar Trask in X-Men: Days of Future Past. 0nnn microfarads), but the capacitor should have a decent voltage rating, of at least a few hundred volts (i.e. The capacitance doesn't have to be very large (I'm guessing, on the order of. Without schematics for the fan and its control circuitry, it's impossible to give a specific recommendation such as "get such and such type of diode and solder it across such and such points".Ī suitable film capacitor connected across the power terminals of the fan maybe able to contain the spike, and would make for a very cheap fix. Perhaps the fan has no snubber mechanism in place to mitigate inductive kicks when the motor is switched off. Containing the surge at or near the fan, or preventing its entry into the motion detector. The problem can be attacked at either end. The voltage levels in the device are disturbed, reversing some voltage comparison so that the light is activated. The motion sensor's circuits are probably being confused by a voltage spike caused by an inductive kick from the fan. ![]()
