The system was designed long ago, all the parts were specified and the installation is finally complete. You should measure about 12.5 VDC at the red and black wires of the sensor. I have a customer with many of the lights and the switches in his house use the RR7 relays and funny looking switches for the lights. Fortunately, relay problems can be fairly simple to diagnose, sometimes the bigger issue is finding a drop-in replacement for an obsolete relay in an environment where ever-changing technology and design can phase out, or completely eliminate various relay models and configurations from the available parts catalog annually. The relay should “click” and the Relay Indicator should change state. Apply power to the relays. The relay got very hot. As agreed, the previous owner kept one of the lights. Confirm the operation by measuring the continuity at the line-voltage terminations of each relay. Relays Troubleshooting. All measurements are made in reference to the blue wire of the sensor. RR7 Sensors: How Can I Troubleshoot GE RR7 Relays And Sensor Switch RR7 Occupancy Sensors? Product Description New GE RR7 maintained relay switch comes equipped with 3 low voltage leads and is the best replacement option for discontinued GE relays for standard unlighted switches. The only problem is that for higher currents, the internal resistance of the transistor decreases. Before we discuss troubleshooting relay-related wiring, let’s review. My son didn’t get a chance to see how the light was connected to the GE RR7 relay installed in the connection box. Remote Control Relay Switch, 277V, 20A, 24VAC Coil, 1P, 6 in. Terminal 85 grounds the […] Problem with GE RR7 low voltage relay. In any circuit with a DIN relay, without looking at a wiring diagram, you know that: Terminal 86 supplies power to the relay’s internal electromagnet. Being careful not to touch any line-voltage wiring, toggle each relay ON/OFF again and confirm that each relay controls the appropriate load. I have replace both switches and the relay, but have the same condition - the light stays on. This is the easiest and accurate way to check and troubleshoot an SSR (Solid State Relay). This is how the sensor is powered. When the relay is ‘off’, the output is open, and shows a very large voltage drop. To test a solid state relay, follow figure and steps given below. Our home has the GE remote lightning (RR7 Relays) I have a light operated by 2 switches that will not turn off. This is the common from the transformer. Last week we talked about the standard DIN numbers used on relays and the incredible utility they represent. Now the real fun begins. GE RR7PBP also replaces discontinued GE RR2, RR3 and RR5, RR7, RR7EZ and standard Bryant low volt solenoid relays; UL Listed 508G; Made in India for GE Lighting Solutions; Operation: Each relay employs a split low-voltage (24V) coil to move the line voltage contact armature to the ON (OFF) latched position. When turned ‘on’, the voltage drops significantly, but is still more than 0. Troubleshooting RIB® Relays. The relay got very hot. There is just one problem, something is not working as expected. The diode test function can still work on a variety of DC output solid-state relays. Body. Troubleshooting a large system with many devices takes a methodical approach, and it is often time consuming and frustrating. My son just moved into an older house that has a few low voltage ceiling light fixtures. 2.
