Arc ok and Torch swtich on the RAV card are stight passthrough to the 4 wide cable. They are simply a convinet place to connect them instead of running them all the way upto the ARC OK and TORCH Switch at the PWM . They are not connected to ANYTHING in the voltage divider circuit. If your 1000 has the rear CPC conenctor and you have the MIC-01 then you dont even need to connect the terminals down at the RAV card...you simply use the CPC connecot and cable into the same 4 wide connector on the PWMEric - Plasma wrote:So I unpluged the connector for arc ok and torch fire from the PWM. Fired the hand torch with it's switch and the VOLTAGE WORKS!
So next I tried a few things to check what resulted:
Switched The raw volts input to the RAV card back to the Hypertherm J15 +J16 connectors = Works
Connected the PWM back up and removed the input arc ok and torch switch wires into the RAV = Not Working
Reconnect everything then removed arc Ok wires from PWM side = Works
Jumpered arc Ok at PWM = Works
Jumpered arc Ok at RAV input = Not working
Ran new arc Ok wires from RAV to PWM = Not Working
Back to original then removed just arc ok wires into RAV = Broken
Back to original then removed just torch switch wires into RAV = Broken
So I thought the arc ok and torch switch signals were separate from the Voltage divider in the RAV card but seems they are not.
Finally getting somewhere thanks sphutley!
make sure the arc ok screw termnals on the RAV cage are connected one to one witht he ARC OK input pins (labeld) at the PWM
IMPORTANT. IF by chance this setup was ever used with a MUCH older Sensor card the ARC was modified and turn into a volage source instead of drycontacts. Find the User manual for the 1000 and tunr to apre 3-14. Make sure the black jumper is set to factory default and NOT for the drigning extgernal relay configuration. That puts 24VDC onthe ARC OK
If the Arc ok and torch switch wires got swapped the torch would not fire and you would get weird ARC OK action.
Its obvious that something is wired wrong beacuse the ARCOK at the RAV is the EXACT same two wires as the ARC OK on the PWM connector.
Shorting themat the RAV should be the same thing as shorting themat the PWM.
Once again the RAV connections are just a passthough so you have screw terminals inside to connect to the signals. They connect to nothing else on the RAV card
