Pump Head Missing
Error ID: 2202, 2212
Pump Head Missing: Pump channel A
B: Pump Head Missing: Pump channel B
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.
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.
