CBX
Analog
Set the analog output channels for sludge blanket depth
(distance D in fig 4) as primary and (optional) second
analog for fluff (distance G in fig 4) if used.. 1, 2, 3, 4, 1&2,
3&4, all or none. Standard is
all
Second
This shows the height of the fluff layer from the bottom
Blanket
Concentration
Set the consistency that will define the blanket. This can
be done by entering a blanket concentration.
Fluff Cons
(optional)
Set the concentration that will define the fluff layer. This
can be done by entering a fluff concentration.
CBX setup
Sub Program for initial CBX set-‐up
Mains
freq
The frequency of the power, i.e. 50HZ in Europe and
60Hz in the USA.
Trig
Number of trig closures before lowering the sensor
CBX Setup
Max depth
The maximum travel distance from home position
(A)
. The
sensor will stop at this depth if no blanket or sludge is detected
(Distance C)
. This travel distance will be shortened if a raker
offset exists
(distance F)
Blind zone Distance B
. Distance to where sensor must travel before it starts
to measure solids. Sludge or foam detected in this zone during
lowering is not registered. Unwanted false blanket depth is
prevented by setting this zone to be approximately 25cm (1 ft)
below liquid surface.
Rake
height
Distanse F
. This denotes the safe height from the bottom (
Max
depth
) to a point where the sensor always must stop and then
turn back to home position to alleviate hitting the bottom rake.
Rake int
The rake switch starts a measuring cycle. When the rake has
activated the rake switch so the CBX will execute a sampling
cycle. It is possible to configure the number of pulses from the
rake switch that is needs for a measuring cycle to start.
Track
Profile
/
Level
. You can set if the CBX shall measure sludge profile
or only sludge and fluff levels. If the CBX is set to
Level
the sensor
will stop when it detects the sludge level and return home.
