| Alarm Code | Description | Probable Cause & Solution | | :--- | :--- | :--- | | | Hydraulic Motor Overload | The hydraulic pump motor drew too much current. • Check the hydraulic oil level (is it low?). • Check for clogged suction filters. • Check the thermal breaker in the electrical cabinet. | | E003 | Hydraulic Pressure Drop | System pressure dropped below the set threshold while the pump was running. • Check for leaks in the lines. • Check the pressure switch setting. • Pump may be worn out. | | E004 | Lubrication Oil Low | The way lube reservoir is empty. • Refill the way oil (typically Mobil Vactra #2). • Check the float switch if the tank is full but the alarm persists. | | E005 | Lubrication Cycle Error | The system did not detect a pressure rise during the lube cycle. • Check if the lubrication pump is working. • Check for blocked lines or a broken distributor block. |
