Error Information
Pump Error Messages
When running certain tests in the diagnostics mode or other special
applications, the pump must wait for the pistons to reach a specific position,
or must wait for a certain pressure or flow to be reached. Each action or state
must be completed within the timeout period, otherwise the error message is
generated.
Possible Reasons for a Wait Timeout:
· Pressure not reached.
· Pump channel A did not reach the delivery phase.
· Pump channel B did not reach the delivery phase.
· Pump channel A did not reach the take-in phase.
· Pump channel B did not reach the take-in phase.
· Solvent volume not delivered within the specified time.
