Boge Compressor Fault Codes -
Comprehensive Guide to Boge Compressor Fault Codes Boge compressor fault codes are diagnostic signals generated by internal control systems, such as the Boge FOCUS or Base Control units, to identify operational anomalies. Understanding these codes is essential for minimizing downtime and preventing mechanical damage. Boge systems distinguish between Warning Messages , where the compressor continues to run while alerting the operator, and Fault Messages , which trigger an immediate safety shutdown. Common Boge FOCUS Controller Fault Messages The FOCUS controller is widely used across Boge screw compressor lines. Below are common codes typically displayed on these units. Typical Causes 1 Final compression temperature too high Choked cooler, low oil level, or faulty temperature module 2 Motor temperature too high Electrical overload, poor ventilation, or motor bearing wear 3 Fan motor fault Tripped fan motor overload or failed fan motor 5 System pressure too high Closed outlet valve, clogged oil separator, or faulty solenoid valve 6 Suction filter differential pressure high Clogged intake air filter 7 Oil filter differential pressure high Clogged oil filter requiring replacement 8 Oil separator differential pressure high Oil separator element is saturated or blocked 12 System pressure decrease too slow Leak in the system or faulty non-return valve 14 Temperature too low ( 16 Net pressure transmitter fault Broken wire or defective pressure sensor General Diagnostic & Operational Codes For various Boge series (S, C, or P series), the system may use alphanumeric codes to categorize the nature of the issue.

Boge air compressors use advanced control systems like Focus , Ratio , and Base Control to monitor performance. When a malfunction occurs, the unit will often shut down and display a specific fault code on the Boge Control Panel . Common Boge Fault Codes & Meanings Fault codes are typically categorized by electrical issues, pressure limits, or temperature sensor failures. Error 5: System Pressure Too High Meaning: The compressor's internal system pressure has exceeded the safety threshold. Potential Causes: A closed outlet valve, a blocked oil separator, or a faulty Minimum Pressure Valve (MPV) . Error 9: No Output/Communication Meaning: Often indicates a failure in the solenoid valve or mechanical drive components. Action: Inspect the drive belts, solenoid valve, and suction regulator. Error 14: Sensor/Controller Malfunction Meaning: A generic sensor error often related to temperature or pressure monitoring. Error 16: Sensor or Controller Fault Meaning: Specifically linked to a faulty sensor or a failure within the Focus Controller itself. Error 48: State Fault Meaning: Often related to the "ready" or "startup" status of the compressor failing to transition. Electrical & Power Faults Electrical codes often start with F or E on newer digital displays: F01: Power supply voltage is too high or too low. F02: Phase imbalance or a complete phase loss. E01: Communication error or sensor malfunction. E02: Control circuit fault.

The Ultimate Guide to Boge Compressor Fault Codes: Troubleshooting, Errors, and Solutions In the world of industrial compressed air, few names command as much respect as Boge. Known for their German engineering, reliability, and efficiency, Boge compressors are the workhorses of countless manufacturing plants and facilities. However, like all complex machinery featuring variable speed drives, sophisticated controllers, and mechanical components, issues can arise. When your Boge compressor stops running or triggers an alarm, the first line of defense is the control panel. This is where Boge compressor fault codes appear. To an untrained eye, these alphanumeric codes can look like gibberish. To a trained technician, they are a roadmap to a quick repair. This guide serves as an extensive resource for understanding, diagnosing, and resolving the most common fault codes found on Boge screw compressors, including the C, S, and D series.
Understanding the Boge Control System Before diving into specific codes, it is essential to understand the interface. Most modern Boge compressors utilize advanced controller systems, most commonly the Boge Touch or the older Focus Control . These controllers monitor critical parameters in real-time, including: Boge Compressor Fault Codes
Discharge temperature Air-end temperature Pressure levels Drive motor amperage Fan operation
When a parameter falls outside of the pre-set "safe" range, the controller triggers an alarm. There are generally two types of notifications you will see:
Warnings (Pre-alarms): These indicate a parameter is approaching a critical limit (e.g., service due or high temperature warning). The compressor usually keeps running, but immediate attention is required. Faults (Cut-outs): These are critical errors that force the compressor to shut down immediately to prevent damage. These require a manual reset before the machine can restart. Comprehensive Guide to Boge Compressor Fault Codes Boge
Top 10 Most Common Boge Compressor Fault Codes While Boge manuals contain lists of specific hexadecimal or numeric codes depending on the controller version, most operators encounter recurring issues related to heat, pressure, and sensors. Below are the most frequent fault categories and codes you will encounter. 1. High Air-End Temperature (Shutdown) Likely Code Display: Temp. Air-end High or specific temperature limits exceeded. This is arguably the most common critical fault on a screw compressor. It means the compression element (the screw block) is overheating.
The Cause: The air-end temperature has exceeded the safety threshold (usually around 110°C–120°C, depending on the model). Potential Reasons:
Low Oil Level: The most common culprit. Without sufficient coolant/lubricant, heat is not removed from the compression chamber. Clogged Oil Filter: A blocked filter restricts oil flow to the air-end. Thermostatic Valve Failure: The valve that regulates oil flow to the cooler may be stuck closed, preventing the oil from being cooled. Dirty Oil Cooler: If the radiator/cooling fins are clogged with dust, the oil cannot dissipate heat. Common Boge FOCUS Controller Fault Messages The FOCUS
Solution: Check oil level immediately. Clean the cooler. Inspect oil filters and the thermostatic valve.
2. Main Motor Overload Likely Code Display: Motor Protection or Overload Main Motor . This fault indicates that the electric motor driving the compressor screw is drawing more current than its rated capacity.
