CBX
-
Set the track to “profile” (settings/CBX setup/track)
The analogue 4-‐20mA assign to the following channels when using “profile”
Channel 1
High of sludge blanket, signal updated every time a new
measurement is done. Scale is the same as (scale/alarms/Max
depth).
Channel 2
High of fluff blanket, signal updated every time a new
measurement is done (scale/alarms/Max depth).
Channel 3
Concentration on-‐line during a sample otherwise 0. Scale is
locked to 0-‐30000 mg/l.
Channel 4
Depth of sensor on-‐line during sampling otherwise 20mA.
Scale is same as (scale/alarms/Max depth)
See graph below how a typical profile can look like when you
have about 1ft of sludge and 3ft fluff on top of the sludge.
See
fig 4
on next page for detailed information how this can be displayed.
