Nexen SC100 964420 - Manual (Page 11)

11 FORM NO. L-21163-C-0808
Set for Individual or Summed outputs.
Individual Outputs:
Output 1 = Channel 1
Output 2 = Channel 2
Summed output:
Output 1 = Channel 1 + Channel 2
Output 2 = Channel 2

Both output channels are equipped with voltage or
current outputs. This is user selectable via CH1 OUT
and CH2 OUT switches accessed through the cover of
the SC100.
Setting output channels:
Using a screw driver or your fi nger, slide the switch to
‘I’ for 4-20 mA output or to ‘V” for 0-10 V output. (See
Figure 16).

The SC100 outputs can be set with both sensor
channels summed together or each sensor channel
separately.
Individual Outputs:
Channel 1 output is an amplifi cation of Channel
1 sensor input. Similarly, channel 2 output is an
amplifi cation of the channel 2 sensor input.
Individual Outputs are generally used for web guide
sensors, different sensor types using the same SC100,
or load cells measuring tension in different tension
zones.
Summed Output:
Channel 1 output is the summation of the amplifi cation
of Channel 1 and Channel 2 sensor inputs. Channel 2
output is the amplifi cation of channel 2 sensor input.
Summed Output is generally used for a pair of load cells
or strain gauges measuring tension in a single tension
zone (See Figure 17).

NOTE: When using the summed output, each channel
must be calibrated separately. This means when a total
maximum output of 10 V is needed, each channel must
be spanned to 5 V.
