Comparator Span % can now be
changed using the RIGHT
ARROW button.
Comparator Span %:
This x represents the maximum
percent of solids readings
difference that is allowable. If the
difference in solids readings
between the MPR E-Scan units
exceeds this limit, a Monitor
error will be activated.
The comparator span is adjustable between 1% and 2%.
Trend Limit:
This is a time frame in minutes that is used for a divert prediction indicator. If a divert is
predicted within the trend limit time frame, a Monitor warning will be activated. The trend limit
is adjustable between 10 and 99 minutes.
Temp. Low:
If the process temperature reading from an MPR E-Scan unit falls below this limit, a unit specific
error is activated and the offending unit is taken offline. An error message will appear in the unit
status window in normal mode and the unit error relay will be turned on.
Temp. High:
If the process temperature reading from an MPR E-Scan unit exceeds this limit, a unit specific
error is activated and the offending unit is taken offline. An error message will appear in the unit
status window in normal mode and the unit error relay will be turned on.
