upon receiving the start command. The user can troubleshoot the reason for the
malfunction by checking the error messages via serial communication and also
referring to the list of suggested actions. While a malfunction is detected, the
electronic unit enters in the FAIL status; once the reason for the fail has been
trouble shooted, the units needs to receive a new start command in order to reset
the FAIL status. As a consequence, if the reason for the malfunction has been
solved, upon the receiving of the new START command, the red led light status will
be immedi atelyturned off and the 305 IC will operate properly, showing the status
(on the serial comm. and by the green led indicatio ns) which is appropriate to the
current work condition (RAMP, NORMAL, etc.).
properlyupon receiving the start command. The user can troubleshoot the reason
for the warning by checking the error messages via serial communication and also
referring to the list of suggested actions. Upon the detection of a warning
condition, the unit continues to work with no interruptions and showing the status
(on the serial comm. and by the green led indications) which is approp riate to the
current work condition (RAMP, NORMAL, etc..).
This because, warnings are not related to any blocking conditions for th e pump
functionality. Once the reason for the warning has been solved, the yellow led
light will be immediatelyturned off, and in the majorityof the cases, the user do not
need to perfomr any further action on the 305 IC Only in a very few cases, in order
to properly reset the warning signal, the user has to power off the unit.
