3.5.2.7 Major Fault
The major fault menu contains the controls for the HiVol restart. When the
flow from a HiVol is insufficient for sampling purposes, resulting in an error
(“Filter Blocked” or “Motor Drive Error or Major Blockage”) the instrument
will stop sampling, then after a delay attempt to restart. This resetting is
controlled by the following fields:
Retry Delay
The number of minutes before the HiVol attempts a restart
Max Retries
The maximum number of times to attempt retrying before giving up. When
Max retries has been reached the operator must then visit instrument and
repair the fault/change filter and hit the exit key.
No. Retries
Displays the number of retries that have occurred since everything was
running fine. Once this number reaches that placed in the “Max Retries” field
(above) the instrument will stop. When the instrument reaches the desired flow
continuously for 5 minutes the “No. Retries” field will be reset to 0.
