Troubleshooting and Test Functions

Wait Timeout

 

Wait Timeout

 

When running certain tests in the diagnostics mode or other special

 

applications, the pump must wait for the plungers 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

Pressure not reached.

Wait Timeout

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 Causes

Purge valve still open.

 

Leak at fittings, purge valve, active inlet valve, outlet ball valve or plunger

 

seals.

 

Flow changed after starting test.

 

Defective pump drive assembly.

Suggested Actions

Ensure that purge valve is closed.

 

Exchange defective capillaries.

 

Ensure pump components are seated correctly. If there are still signs of a

 

leak, exchange the appropriate seal (purge valve, active inlet valve, outlet

 

ball valve, plunger seal).

 

Ensure correct operating condition for the special application in use.

 

Exchange the defective pump drive assembly.
