The HiVol’s data logger collects data even when the blower motor is not
running. The data are collected at regular intervals, called the averaging
period. The averaging period is set in the Logger Setup menu. The data that
are logged are the average data value during the averaging period, with the
data being written to memory at the end of that period.
Data from up to 150 averaging periods may be stored in the HiVol. Once the
data logger memory is full, the HiVol stops collecting data. The HiVol begins
collecting data when the logger accumulator is cleared. When setting the
averaging period, keep this in mind. If you want to collect one day of data, it
will be necessary to set the Logger Setup Averaging period to at least 10
minutes. If the averaging period is set to one hour, up to 150 hourly averages
of data will be collected. This equates to over 6 days of logged data.
The actual number of data points can vary depending on the number of
characters being stored, which can change according to the values being
stored.
Note: Data are also collected when
the HiVol is in Manual mode.
Setup Major Faults menu
When the flow from a HiVol drops considerably, an error occurs and the
instrument stops sampling, then after a delay, it attempts to restart.
“Filter Blocked” error is displayed when a drop in flow occurs and indicates
that the filter is full/saturated with particulates.
“Motor Drive Error or Major Blockage” error is displayed when the drop in
flow is large and is caused by:
• The blower motor not working properly (motor breaking down)
• Either a high or low supply voltage to instrument
• Large blockage within the instruments flow path
When sampling with a Size Selective Inlet the instrument must remain at a
specific flow for the SSI to take representative samples. When the blower
motor is unable to reach the required flow rate for 2 minutes a filter blocked
message is displayed and the unit stops sampling.
The instrument will attempt to reset itself a number of times (user definable)
and if unsuccessful the instrument will shut down until an operator visits the
instrument and repairs the fault/changes the filter and hits the exit key (see
section 3.5.2.7 for more details).
