Wait Timeout
Error ID: 2053
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.
Probable cause Suggested actions
1
Purge valve open.
Ensure that purge valve is closed.
2
Leak at fittings, purge valve, active inlet
valve, outlet valve or piston seals.
• Ensure pump components are seated
correctly. If there are still signs of a leak,
exchange the appropriate seal (purge valve,
active inlet valve, outlet valve, piston seal).
• Exchange defective capillaries.
3
Flow changed after starting test.
Ensure correct operating condition for the
special application in use.
4
Defective pump drive assembly.
