Product Introduction
Compressor panels are easy to misidentify. The part number looks close enough, the label is worn, and the system is down. That is where P3798102-00010 CN-UIM2 usually shows up — as a replacement request during an unplanned compressor outage.
The COOPER P3798102-00010 CN-UIM2 is an operator interface panel used in COOPER turbo compressor control systems. It provides a local interface for monitoring compressor operation and interacting with the control system. In the field, it typically sits on or near the compressor control cabinet and gives operators access to key process data such as pressure, temperature, flow, and machine status.
This is not a generic HMI. It belongs to a specific COOPER compressor control architecture, and compatibility depends on the compressor model, control cabinet revision, and internal board layout. Treat it as an application-specific spare. If the existing panel is labeled P3798102-00010 CN-UIM2, match the suffix exactly before swapping.
QA/QC Transparency SOP
- Intake & Origin Verification: Confirm the full part number P3798102-00010 and variant CN-UIM2. Check for physical damage, cracked displays, burnt connectors, or corrosion from cabinet humidity.
- Visual & Mechanical Inspection: Inspect ribbon cables, terminal blocks, display connectors, and mounting hardware. Reject units with swollen capacitors, cracked PCBs, or damaged display bezels.
- Power-Up Test: Apply the correct supply voltage per the OEM manual. Verify display illumination, keypad response, and boot sequence. Do not force power if the input rating is unclear.
- Communication & I/O Check: Verify communication with the compressor controller and confirm that process values read back correctly. Check for alarm flags, communication timeouts, or stuck analog channels.
- Final QC & Packaging: Record the test results, label the unit with part number and revision, and pack in anti-static material. Surplus panels should be sold with clear “tested / as-is” status unless full OEM calibration is available.
Field Engineer Gotchas
- Suffix mismatch risk: CN-UIM2 is not the same as other UIM variants. A panel that physically fits may still have different firmware, addressing, or I/O mapping. Verify the full label before installation.
- Compressor-specific configuration: This panel is tied to COOPER compressor control logic. Dropping in a spare without loading the correct configuration can produce wrong setpoints, false trips, or missing alarms.
- Display and keypad failures: Older compressor panels often fail at the display or membrane keypad first. If the controller is healthy but the panel is unresponsive, isolate the fault before replacing the entire cabinet card.
- Wiring identification errors: Compressor panels carry critical signals — surge control, pressure, temperature, and shutdown inputs. Mislabeling one pair during replacement can create a dangerous control mismatch.
- No public OEM datasheet: Do not assume voltage, protocol, or mounting dimensions from third-party listings. Pull the OEM manual or match the removed unit exactly.

Application Scenarios
- Turbo compressor surge control monitoring: Operators use the panel to watch discharge pressure, suction flow, and temperature trends during load changes.
- Process gas compressor packages: Used on COOPER/Cameron compressor trains in refinery, chemical, and gas processing services where local access is required during startup and shutdown.
- Legacy compressor maintenance: Replacement of failed operator panels on older compressor skids where the main controller is still serviceable.
- Case note: A chemical plant lost local visibility on a process gas compressor after the operator panel display failed. The controller remained online, but operators could not confirm setpoints locally. Replacing the failed interface with a verified P3798102-00010 CN- restored local access after the configuration was confirmed against the existing controller backup.
FAQ
No. It is an operator interface panel used within a COOPER turbo compressor control system, not a standalone PLC.
What compressor systems does it fit?
It is associated with COOPER turbo compressor control systems. Exact compatibility depends on the compressor model and control cabinet revision. Confirm against the existing nameplate.
Can I substitute another CN-UIM panel?
Not safely. UIM variants may differ in firmware, wiring, display type, or controller compatibility. Match the full part number and revision.
Does this panel include the compressor control program?
Usually not. The control logic typically resides in the main compressor controller. The panel provides the local interface. Configuration must be verified after replacement.
Is this part still available from COOPER?
Availability should be confirmed with COOPER, Cameron, or an authorized surplus supplier. Many listings are aftermarket or surplus stock.
What should I check before buying a surplus unit?
Verify the full part number, revision, display condition, connector integrity, and whether the seller has performed a power-up test. Request photos of the nameplate and internal board before payment.
