Error types
The pump handles errors differently depending on the error type. There are
four error types, described below and listed in Table 5-13 (page 87).
Immediate errors
These include:
• Invalid command (error 2)
• Invalid operand (error 3)
• Invalid checksum (error 4)
• Plunger move not allowed (error 11)
• Device not initialized (error 7)
Any subsequent [Q] command will report the error. In certain cases, the
answer block immediately returns an error.
Note: There is no need to reinitialize the pump following this type of error.
Initialization errors
These include:
• Initialization error (error 1)
• Device not Initialized (error 7)
To ensure that the pump initialized successfully, send a [Q] command after
the initialization [Z], [Y] or [W] command.
• If an error occurs during initialization, an initialization error (error 1) will be
returned in response to the [Q] command. The pump must be reinitialized
until the [Q} command indicates successful initialization.
• If the response indicates both a successful initialization and that the pump is
ready, subsequent move commands can be sent.
• If initialization is not successful, or if any plunger move command is sent
prior to an initialization command, a device not initialized error (error 7) is
returned in response to the command.
Overload errors
These include:
• Plunger overload (error 9)
• Valve overload (error 10)
If the pump returns either of these errors, the pump must be reinitialized
before continuing.
If another plunger or valve movement command is sent without reinitializing
the pump, the initialization error (error 1) will be returned.
Command overflow error
This error (error 15) occurs when certain commands are sent to the pump
while it is busy executing another command string. The pump ignores the
new command and issues a command overflow error.
Any move, setting (except [V]), or valve commands that are sent while the
pump is busy will cause this error to be issued.
