7.3.4. Screen 4: Aux Inputs
The Aux Inputs screen is used to set the
characteristics of certain input types that may be
required by the MultiFlex CUB.
Specifically, if you are using power trans-
ducers, you must enter information in this screen
that helps the CUB translate the KW transducer
signal into a KW value.
Also, if you are using a linear sensor type
that is not supported by the CUB, you can assign
it to one of the three spare Linear sensor types.
You must enter the voltage and output ranges for
each Linear sensor type if you wish to do this.
KWH Per Pulse
If you are using a pulse accumulation type
KW transducer, you must enter the number of
KWH per pulse for this transducer in this field.
Otherwise, leave this field set to
NONE
.
KW Analog Min and Max / KW Min Volts and Max
Volts
If you are using an analog KW transducer,
you must enter the voltage range of the input and
the range of KW values the voltage corresponds
to. This information is different for each KW
Transducer and depends on the line voltage and
current transducer (CT) rating. Refer to your
KW transducer’s installation instructions.
Linear 1 and Linear 2 Fields
If you wish to use a sensor type not directly
supported by the CUB, and the sensor type has
an output voltage between 0 and 5 volts DC, you
may assign this sensor one of the two Linear
sensor types (Linear 1 and Linear 2). You may
then connect the sensor to a point on the CUB
and designate the point as sensor type Linear 1
or Linear 2 (see
Section 7.3.3., Screen 3:
Inputs
).
To configure one of the Linear sensor types,
you must enter values for each of the four fields:
•
Minimum Out
-
The smallest possible value of the
sensor’s input value. Enter this number in the engi-
neering units you will be using for this input.
•
Maximum Out -
The largest possible value of the
sensor’s input value. Enter this number in the engi-
neering units you will be using for this input.
•
Minimum Volts -
The raw voltage value of the sen-
sor that corresponds to the value you entered in the
Min Out
field.
•
Maximum Volts -
The raw voltage value of the sen-
sor that corresponds to the value you entered in the
Max Out
field.
7.3.5. Screen 5: CUB Inputs
The CUB Inputs screen is where you specify
the type and functions of all the sensors, trans-
ducers, and contact closures connected to the
MultiFlex CUB.
