Pump Head Missing
Error ID: 2202, 2212
The pump-head end stop in the pump was not found.
When the pump restarts, the metering drive moves forward to the mechanical
end stop. Normally, the end stop is reached within 20 s, indicated by an
increase in motor current. If the end point is not found within 20 s, the error
message is generated.
Index Limit
Error ID: 2203, 2213
The time required by the piston to reach the encoder index position was too
short (pump).
During initialization, the first piston is moved to the mechanical stop. After
reaching the mechanical stop, the piston reverses direction until the encoder
index position is reached. If the index position is reached too fast, the error
message is generated.
Probable cause Suggested actions
1 Pump head not installed correctly (screws
not secured, or pump head not seated
correctly).
Install the pump head correctly. Ensure nothing
(e.g. capillary) is trapped between the pump
head and body.
2 Broken piston.
Exchange the piston.
Probable cause Suggested actions
1 Irregular or sticking drive movement.
Remove the pump head, and examine the seals,
pistons, and internal components for signs of
wear, contamination or damage. Exchange
components as required.
2 Defective pump drive assembly.
Please contact your Agilent service
representative.
