Pump Status
The Pump Status indicates the operating status of the pump.
The possible Status are the following:
Stop = the pump is waiting for a START command
Ramp = the pump has been started and is increasing the
rotational frequency in order to reach the target set point
Normal Operation = the pump is running at the target frequency
Fail = the pump is not running because has been detected an
error condition. The error condition can be discovered reading
the W206 value throug serial communication interface
Autotuning = the pump rotational speed is not able to reach (or
maintain) the target value due to a too high gas load.
The Pump Status can be detected by looking at the STATUS LED or
reading the W205 value throug serial communication interface.
