Display Error Codes - Graco TruMix XT 2003102 Operation Instructions And Parts Manual

Display Error Codes

If any error codes are active, the lowest numbered error code will scroll across the display until the error is cleared.
NOTE: Errors can be cleared by placing the dispense switch in the OFF position (errors will only clear if the error
condition is resolved).
NOTE: The system will not operate while any errors are present. A prime is required after all error conditions are
resolved before the system will be allowed to dispense on ratio again.
