5 Hello, There should be a 2 digit number that follows the "HL.P" error code. Please refer page 42 of the manual or read below. HLP 20: Indicates a failure of meter display module PC2, or the wiring between PC2 and main control module PC1. If this display is shown, have Factory Authorized Service Agent check PC1, PC2, and the wiring between PC1 and PC2. HLP 21: Indicates thermistor TH1 on the main rectifier heat sink has failed. If this display is shown, have Factory Authorized Service Agent check TH1, and the wiring between TH1 and PC1. HLP 22: Indicates the rectifier heat sink has overheated. If this display is shown, check generator cooling system and/or reduce duty cycle. Keep engine access door closed when running to maintain proper cooling air flow past rectifier. Allow unit to cool before restarting. If problem continues, have Factory Authorized Service Agent check unit. HLP 23: Indicates one of the rectifier output SCR’s has failed. If this display is shown, have Factory Authorized Service Agent check the rectifier SCR’s. HLP 24: Indicates weld open circuit voltage (OCV) is too high (above 41 volts dc). If this display is shown, have Factory Authorized Service Agent check main control module PC1. HLP 25: Indicates a remote device connected to Remote Receptacle RC14 may be faulty. Help 25 is also displayed whenever a remote device has been connected to RC14 and then disconnected. Clear fault by stopping and restarting the unit or by turning Process/Contactor switch to another position. If problem continues, have Factory Authorized Service Agent check the remote device, filter board PC6, and main control module PC1. If you have any other questions, please reply to this answer. Thank you. Best, James
