Module Error Messages
Index Missing
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
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.
Probable cause Suggested actions
