In the above table the shaded cells indicate flow rate recording whilst the white cells indicate detector and
alarm level recording.
At the slowest recording rate, one month of data can be recorded. The factory default setting is 8.
2.8.3 Separator
Condition
The value given at this function is the efficiency rating of the dust separator element in the detector as a
percentage of the efficiency of a clean separator. A new element will give a reading of 99 in this function.
When the efficiency has decreased to 80%, the Fault indicator LED will illuminate and the event log will
show “Separator renew”.
NOTE: Fitting a new element will reset this figure to 99
2.8.4
Separator Change Date
This function defaults to “--“, which means that a separator fault will only appear when the efficiency
decreases to 80% (see 2.8.3, “Separator Condition”). However, a date may be entered into this function
