    Default OSP 700L - where to find PLC output info?

    We have an Okuma Crown 762-SBB, with an OSP 700L control.

    The machine has an intermittent problem with the chuck clamp, generating Alarm 1725 LS-Sol mismatch.

    This occurs when the machine is supposed to clamp but doesn't.

    We are trying to diagnose the problem. We initially thought it was the cable, from the Multi-port to the Solonoid valve. Changed that and still have the problem. Now thinking multi-port, or maybe the solenoid??

    Rather than throw parts at it, I am trying to find the outputs within the control diagnostics to see if the control is actually telling the solenoid to fire. I can locate the inputs, to see that the pedal is being activated, and when the clamp/unclamp switches on the back of the solenoid are being made. However, I cannot find the pages showing the outputs.

    Can anyone tell me where/how to find the outputs in this control?
