Diode of the transducer work state:
- the state diode lights in green – normal
work,
- the state diode lights in red – improper work
parameters; one must configure the trans-
ducer again,
- the state diode pulsates in red – lack of
calibration or the non-volatile memory is
damaged; one must return the transducer to
the manufacturer.
Confirmation of the separator’s communication with PD14 programmer
is indicated by the status diode which turns off for short period of time.
