The terminals are normally marked, either by the terminals, or on the terminal cover. For instance if C to S reads .02 ohms and C to Run = .04 ohms, then C to R should be around .06 ohms. 2 Answers. If you measure between the run winding and the start winding, you should get the sum of the other two readings. C – R = 4 Ohms. I assumed the P must be a rubbed off R and V may be a rubbed off Y. With the system pressure lowered, it is now safer to remove the plug and test the compressor terminals directly. Recreational Supply Corporation? The Red wire from the 5-2-1® start kit is normally connected at the “C” or “=” terminal on the run capacitor, but … all electricity for it to work needs a path a load and a source. December 8, 2018. Step 5 Run the fan motor and compressor's wires to the electrical service box. This is different from a single phase compressor which will have 3 terminals listed as S, R, and C (Start, Run and Common). Wired. G or G1. Pump Down First, many scroll compressors won’t even allow you to pump them down into a vacuum. It is a red wire and comes from the transformer usually located in the air handler for split systems, but you may find the transformer in the condensing unit. The suction pressure at the compressor is 43 psig and the condensing pressure at the compressor is 260 psig. On a 3 phase compressor, you will see the terminals listed as T1, T2, and T3. But it still won’t start. There are three different terminals in most a/c compressors. Answer Save. Blue: Two blue low voltage wires to operate the contactor relay magnet. Locate the compressor's start relay and pull it off the terminals on the side of the compressor. C.S.R Compressor Wiring Diagram Single Phase With voltage Type Relay. Beri huruf [ tanda pada terminal ] misalnya A.B.C. is it common, start ... . Power from fan relay to fan motor will typically connect to the T2 terminal on the Contactor relay. If the compressor passes the above tests, take a multimeter set to R x 10,000 (10K) and check each winding to ground. I wonder if I could use the H terminal to run a wire to W on the furnace.

R goes to the other. * C.S.R adalah singkatan dari: C : Common S : Start R : Run. So compressor terminals. Example – C -S = 7 Ohms. Step 4 Examine the top of the capacitor. If you have resistance between Start+Run and have OL at the others, then you the compressor could be off on overload (check if compressor is hot with back of hand or better yet an infrared thermometer). Yes, L1 of the single phase supply is terminated under terminal L1 of the three phase contactor. C goes to one leg of power. im not so sure though. What is the problem with the motor? I have an old Lennox and it’s terminals are G, P C, H, V. I can’t get it to work so It may have problems. R – The R terminal is the power. Temp. While the thermostat supports 2-stage operation, it currently is configured for one-stage, as that's all the old furnace was. If you have a two-stage compressor, Y2 controls your compressor’s second stage, allowing for different levels of heating and cooling. Ukur tahanan masing-masing terminal dengan avometer pada sisi range ohm. Feeling Alive All Over Again!!!! See the picture for reference. Run, Start and Common.

The Compressor/Condenser unit is connected to B/C and Y only. With 208v or 240v circuits the L1 and L2 high voltage incoming lines make no difference which is which when you connect. Either they are equipped with a low pressure cut out or some sort of low pressure / low compression bypass like shown in this USPTO drawing. Lastly, if you have a package unit, then the transformer is in the package unit. G or G1 controls your HVAC fan. Vapor-compression uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere.

The letters stamped into the compressor's housing near the wire terminals identify each terminal function. A single-phase compressor has three slide-on terminals. This system dries and cools the interior of the SUV. In a few cases, the terminals might not be marked. Still have questions? Confusing. Thanks delack. Google Arts & Culture features content from over 2000 leading museums and archives who have partnered with the Google Cultural Institute to bring the world's treasures online. Compressor nominal capac- ity at rating conditions to two signi fi cant digits. Favorite Answer. Inside an air conditioner compressor is a motor with two windings: a high-current coil called Start, and a low-current coil called Run. Compressor Family Series Either a number or a letter established for each product model. Now we must apply this information to the curve sheet. Record resistance values for the following C-S, C-R, S-R. On an operational compressor you may see readings as follows C-S 3Ω, C-R 1Ω, S-R 4Ω.. Common- Start will always have a higher resistance value than Common - Run as the start windings are heavier to deal with the in rush current required to start the compressor.
