Module Error Messages
Index Missing
Error ID: 2205, 2215, 2505
Index Missing: Pump channel A
B: Index Missing: Pump channel B
The encoder index position in the module was not found during
initialization.
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 not recognized
within a defined time, the error message is generated.
Stroke Length
Error ID: 2206, 2216
Stroke Length: Pump channel A
B: Stroke Length: Pump channel B
The distance between the lower piston position and the upper mechanical
stop is out of limits (pump).
During initialization, the module monitors the drive current. If the piston
reaches the upper mechanical stop position before expected, the motor
current increases as the module attempts to drive the piston beyond the
mechanical stop. This current increase causes the error message to be
generated.
