BOGE Compressor Error Codes - Quick Reference
BOGE rotary screw compressors (S, C, and BLUEKAT series) use the BOGE Control and BOGE Select electronic controllers. Alarms display as text or numeric codes depending on controller generation.
| Code / Alarm | Meaning | Quick Fix |
|---|---|---|
| High Final Pressure Temp | Discharge temp too high | Clean cooler, check oil |
| Low Oil Pressure | Lube circuit fault | Check oil level and filter |
| Motor Overload (OL) | Motor overcurrent | Check amps and phase balance |
| E-Stop | Emergency stop active | Reset and inspect |
| Service Interval | PM due | Perform service, reset counter |
| Air Filter Diff. High | Air filter blocked | Replace air filter element |
| Oil Separator DP | Oil separator restricted | Replace separator element |
| Pressure Regulator Fault | Regulator not maintaining set point | Check regulator and solenoid |
| Phase Monitoring | Phase loss or reversal | Check supply wiring |
| Temperature Sensor | Sensor out of range | Check sensor wiring |
Most Common Faults
High Final Pressure Temperature
BOGE screw compressors are sensitive to oil cooler cleanliness. The cooler fins on BOGE units pack densely and require cleaning from the inside out with compressed air or a fin brush. Verify the cooling fan capacitor - a slow fan is a common cause that’s easy to overlook.
Air Filter Differential High
Some BOGE models have a differential pressure switch across the air filter. A clogged filter reduces airflow, increases velocity through the airend, and causes temperature rise. Replace the filter element before it triggers this shutdown.
Oil Separator DP
The separator element is a scheduled service part - typically 3,000–4,000 hours. In dusty environments or with degraded oil, it can plug much sooner. A high differential pressure across the separator increases power consumption noticeably before triggering the alarm.
Parts Often Needed
| Part | Notes |
|---|---|
| Oil separator element | Amazon | Primary PM item |
| Air filter element | Amazon | Replace per service schedule |
| Oil filter | Amazon | Replace with separator |
| Cooling fan capacitor | Amazon | Common on single-phase fan motors |
| Discharge temperature sensor | Amazon | Thermocouple or NTC type |
When to Call a Pro
BOGE compressors require factory-specific oil types and torque specs on separator housing reassembly. If repeated temperature shutdowns occur after service, contact a BOGE authorized service provider.
