I have an old air compressor that I have replaced the motor magstart and pressure switch on the motor is a 220 / 240 volt 5 horsepower motor it also has a low pressure oil cutoff switch does anybody have a...


Control: L1-SS-P-O-OL-OL-M-L2 In series, L1 is line 1, SS is start/stop switch, P is pressure switch, O is oil switch, OL is overload contact, M is magnetic coil (solenoid), L2 is line 2.
The voltage of M must be rated for the control voltage, across the line voltage (240V) or of a control transformer voltage, e.g. 240v/24v. A control voltage would be wired across the line, to L1 and L2.
Power: L1-T1-OL-M1, L2-T2-OL-M2. Line one to Line 1 on contactor, T1 on contactor jumpered to OL (overload heater) and out the overload heater terminal M1 to the motor terminal 1. Same for line 2, Line 2 to L2 on contactor, T2 on contactor jumpered to OL (overload heater) and out the heater overload terminal to M2 motor terminal.
The heater overload relays needs to be chosen by the motor full load current, a chart is given with a motor starter on selecting heater size. If no chart is available, go 115% of the motor FLA (full load amps) to select a heater size. E.G. 25 FLA motor at 115% is 28.75a. Sorry, no schematic available now, draw your own from this info. If using 3 phase, add the third line as duplicating one other line1 or line 2

Wire a 220v heater to a transformer, contactor, and thermostat


one side of transformer secondary to one side of contactor coil. the other side of transformer secondary thru t stat to other side of contactor coil. line voltage 220v to l1, l2 of contactor . other side of contactor to load (220v heater. ) Make sure heater has some sort of overload /overheat safety either breaking line voltage or control voltage 24v.

Wiring Diagram


I think you would probably find what you are looking for by going to the manufacturer web site : www.yaskawa.com

There is no way that anyone here can find what you are looking for. Incremental encoders are used for anything from robotic assemblers to elevators - unless you provide a lot more information about what it is you are wanting a wiring diagram for, there is no way anyone is going to be able to help you.

My model ACD2234HRQ is approx 90 days out of


you need to replace the rtc overload contactor located on the compressor body,there is also a run capacitor on the contactor,replace this along with the rtc contactor,this is your problem,the contactor and overload give the compressor starting power and run power to the windings,if the capacitor is bad it doesnt have enough torque to overcome the power to turn the compressor initially

Ruud heat pump outside unit trips circuit breaker


Check your wiring between the contactor and compressor for a short to ground, or check the compressor windings for short to ground.
With the Tstat off, the contactor should be open so the only way for the compressor to be trying to do anything is if the 110 volts from the unbroken side are traveling through the compressor to ground. Since 110v is not enough to run it, the overload is kicking it out, cooling off, and repeating the cycle. When you kick on the Tstat, the contactor is supplying voltage directly to ground without going through the resistence of the compressor windings and kicking the breaker.
Post back and let me know what you find.
