Attention
Unlock codes, for the different user levels, are managed by Danfoss technical support team and can only be aquired by
directly contacting the Danfoss technical support team!
Danfoss has developed a service tool (PLUS+1 SERVICE TOOL), and recommend the tool for:
• Changing parameters in the EEPROM
• Download of Software and bootloader
• Enable/disable diagnostic messages (status messages 1 - 7) on the CANbus
• Execute auto-calibration functionalities for WAS and Spool
• Controlling the spool manually for diagnostic purposes
• Extracting diagnostic data from the PVED-CLS (error history, temperature histograms etc.)
