The driller's console is where handwheel setpoints, assignment switches, and indication all come together. PC1 is the card carrying that interface into the SCR system. Faults here look like control problems rather than power problems: a handwheel that does nothing, indication that disagrees with what the equipment is doing, or an assignment that will not take.
Most people arrive at this page from a symptom, not a part number. These are the failure signatures associated with this item. They are starting points for diagnosis, not a substitute for it.
| What you are seeing | What it usually indicates |
|---|---|
| Handwheel produces no response at the motor | Setpoint not reaching the drive |
| Console indication disagrees with actual equipment state | Interface or indication path degraded |
| Assignment will not take or drops out | Assignment logic path |
| Intermittent control that worsens with vibration | Connector or card-edge issue — inspect before replacing |
Revisions differ across the production life of this equipment, and on some Ross Hill items the dash suffix carries a calibration rather than a revision level. We verify the exact dash number and revision against the physical unit before quoting, and we will send photos of the plate on the unit we are offering.
Send a photo of your nameplate, or type out what it reads, and we will match the revision rather than guess at it.
Supplied as new-surplus (unused, from the secondary market), used-tested, or reconditioned, with condition disclosed before sale and photos on request. Availability on legacy Ross Hill and NOV items changes constantly — send the number and we will tell you what we can actually find rather than quote something we cannot deliver.
