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.
Index Missing
Error ID: 2205, 2215, 2505
The encoder index position in the module was not found during initialization.
During initialization, the first piston is moved to the mechanical stop. After
