I am powering this off a motion sensor and it has a lot of buzzing/clicking when on. I remove the motion sensor, it works fine. What am i doing wrong?

I,m not sure but I expect there is an incompatibility between the electronics of the motion sensor and the relay coil. If the relay works properly using an on/off switch, it is likely that the motion sensor not the relay is at fault.

It sounds like low voltage coming out of motion sensor, or the coil amps are higher than the ampacity of the motion sensor contacts. If neither is true, then the motion sensor could have bad contacts. Is the motion sensor rated for 120VAC on the contacts?

If I understand correctly: If you are using the motion sensor to control this relay, the motion sensor itself may not be giving the necessary voltage or output to operate it correctly. All I can add is to make sure you have the power leg and switch leg on properly. A multi-meter (reading volts) could help find your issue. Hope this helps.

Several things could be the problem. Ensure that the motion sensor puts out AC rather than DC. Also, that it is connected as the only power source for the the coil. That is the side connectors. One side Hot the other Nuetral/Ground. The Volt also need to be 120-110 If you have a voltage drop through the sensor that could also cause the malfunction. properly working it will have a loud cluck sound when it turns on and off but otherwise it not make any unusual sound.

I don't believe you are doing anything wrong. However, the motion sensor may be defective or doesn't have the amperage capacity to keep the coil engaged. My application was with a light sensor that didn't have capacity to service the load but could handle the coil load requirement of the contactor.

Andy - I connected my contactor to a Variac and measured the coil current. I measured the following: Pull-in current 145mA to 155mA. Sustaining current 60mA. Drop out current about 30 mA. The solenoid buzzed really badly if the available current was LESS than 145 mA at pull-in, which leads me to believe that your problem is the output driver on the motion sensor can't provide enough current to pull the contactor in. You can measure the sensor output current to the contactor coil by CAREFULLY connecting a multimeter, set to the 10 amps AC scale, in series with your coil drive circuit, and monitor the amount of current it's putting out while the contactor buzzes. Be careful, 120 volts. If your driver can't provide the current to drive the contactor, one way around this would be to use a second, smaller relay to pull in the bigger contactor. Typical "ice-cube" 120v coil relays just require ~ 10-20 mA to pull in. Then this small relay's contacts could activate the coil of the larger contactor. If your motion sensor is providing the proper current then the problem may be related to noise, but I'd check your driver circuit's current capability first. Greg Walz greenlite350@aol.com

this type of contactors usually does not work well with motion sensors,...try using instead electronic contactors with switching current that matches the output current of the motion sensor...hope this helps...

Use fresh batteries. It will provide a good shock if your batteries are new. You will also hear it humming louder at the control box.

Hard to say without seeing it. Double check your wiring and your settings. It could be a loose wire, for example, or maybe the sensitivity is turned up too high. I set up the sensitivity on mine to come on right as you walk through the door. Also, if you have the time turned all the way down (test position), it will stay on for like 30 seconds and then shut off. That's the shortest setting. If it's coming on and off in shorter intervals than that, there is likely an issue with how it was connected.

The buzzing is only present when the backlight is less than 10. I believe its the flourescent bulb buzzing similar to when typical flourescent bulbs are used with a dimmer. I haven't found the sound to be any louder than the fan/hard drive in my Tivo so I'm not worried about it.

Mine just started buzzing. I have cfl's in my ceiling fan. I turn them off and the buzzing stopped. I just don't know why it just started to do this at this time because I've had this setup for almost a year now. Oh well, thanks to everyone who contributed.

Make sure the arrows on power adapter connector and the light strip are lined up. Also hit some other buttons on the remote. Could be a damaged sensor.

I have the same problem too. I just bought this LED 55 in for 2 months and it is making horrible buzzing sound. With the backlight setting to 10, the sound is very obvious, and it will get louder as I watch TV longer, like more than 1 hour.I bought service warranty with Frys, the technician came in and tried to replace the power supply because he thought it was the problem. Turn out the problem was not caused by the power supply but the TV itself he said.I just opened a ticket against Samsung, the Engineer will come over next week to take a look.

Mine is definitely silent. It only buzzes/clicks when there is a power fluctuation, which is very rare. I'd suggest to check your line voltage at the outlet before condemning the unit. If that's ok, then yes, your unit may be faulty.

That's strange, try to make some noise, it has a sensor. Mine is working as plug n play.

Mine does not hum, I use it as an automatic transfer switch in the living room, it's been on 24 hrs a day for a month with zero noise. I would return it and try another one.

Try unplugging the AC power plug, spin the plug 180 degrees, and plug it back in. Occasionally a buzz can be created when the power is "out of phase" with something else plugged into the AC circuit.

Below is a list of checks you can go through to see if the problem is the remote, sensor or something else.*are the batteries on the remote blocked by a plastic strip?*is the sensor plugged into the power supply (not provided with this kit)?*is the LED strip plugged into the sensor (not provided with this kit)?*did you point the remote at the sensor, aiming at the black colored receiver on the sensor, and press the power button on the remote in the top right hand corner?*If you have done all of these try mixing and matching the remote to the sensor and see if any combination work. It is weird to have 3 sets that don't work.Sorry if any of these things seem basic.

I am getting the same thing. It is a buzzing/loud humming noise. Anybody know if this is a defect or if something else can be creating this?

As said below. Read 7.14 of the booklet at the bottom of page 10 and the top of page 11, you just have to set the motion sensor to "off"

I couldn't get it to work properly. I decided to go with this from ebay. Woks perfectly. http://www.ebay.com/itm/New-Automatic-Infrared-PIR-Motion-Sensor-Switch-DC-12V-24V-8A-Detector-Practical-/261479825604?pt=LH_DefaultDomain_2&hash;=item3ce16980c4

I haven't noticed any buzzing at all. It's in a lamp beside couch. I think would notice if it was an issue.

I'm not sure. I'm still having intermittent problems, sometimes i'm unable to turn off the light. I'm thinking of disabling the light and installing a motion sensor light in the garage. Hope this is of some help,,,,,
