the last item of installing the TU 250
300 or 50 400 SC process turbine imager
consists of configuring the digital or
analog outputs for communication to a
programmable logic controller or other
type of digital control system while
this video will demonstrate the easy
steps necessary to configure the analog
outputs on the SC 200 the digital
settings such as Modbus or profibus
registers are available for easy
download at WWF can we start the process
by pressing the Menu key and scrolling
down to the SC 200 sete up menu the
output setup is 1 down and by default
every SC 200 includes 2 for 220 or
analog output devices an additional 3
outputs are available by purchasing an
optional card which can be loaded inside
the controller notice output 1 is
pre-configured by default to the serial
number of the tu 5300 in use output 2 is
currently not set to any source so
output 1 we will configure activation
select source set parameters set
function transfer and filter are all
different ways we configure the output
the source allows you to select which
device you want the output to monitor in
this case the serial number of the
turbine imager is appropriate the
parameter depends upon the sensor and
for the 5300 we have both the turbidity
value or the flow rate in this case
we'll use the turbidity value function
provides four different ways that the
analog output will monitor or reflect
the turbidity value most all cases will
use the linear control in which every
turbidity value will end up with a
proportional
in a linear fashion these other three
options are available and further
details can be obtained in the SE 200
and or set transfer provides the user
with an optional output during
maintenance and calibration items during
those times you can either hold outputs
you can keep the outputs live or you can
transfer the current to a preset value
determined here for example you can
always output two milliamps or perhaps
22 milliamps when the device is being
maintained or calibrated finally set
filter is a signal averaging or
smoothing function so in this case the
default is zero seconds but if you
wanted the four to twenty or analog
output to be signal averaged to smooth
its response you could input a filter
time in seconds in this particular
location if we scroll back up to
activation these are the most important
two settings the low value and the high
value so in this particular case the low
value represents the turbidity in NTU
that will be proportional or equivalent
to a four milliamp output curve the high
value is the turbidity and NTU that will
be equivalent to a 20 milliamp analog
output so we want to make sure these are
appropriately set so that they are
understood and communicate well with a
digital control system so the low value
by default is zero and to you this is
adjustable by the user but normally zero
NTU the bottom end of the
300 is appropriate so we'll leave that
alone scroll down to the high value and
this is typical by default the high
value is set to the full maximum
operating turbidity or value from the
sensor in this case a thousand and to
you if we used a thousand we would
probably have poor resolution in the
analog output so we'll change this to a
more appropriate value something like
one end to you the user could decide for
themselves what's appropriate to convey
possible turbidities while still
retaining good resolution so 1 and T you
will use and that's it we can go back to
the main menu or the home screen by
pressing the home and our turbidity
value now is being output as 6.1 6
milliamps which is appropriate for the
way it's been set up
