Wiring
The wiring terminals for the SC468/SCL468 are compression
type. To open the wiring terminal, turn the screw for that
terminal counterclockwise. Slide the wire into the terminal
space. While holding the wire in place, turn the screw
clockwise to tighten. The wire should be held snugly in place.
Power for the SC468 is 85 to 265 Vdc/Vac 50 to 400 Hz.
Power for SCL468 is 12 to 28 Vdc/Vac 50 to 400 Hz.
Wire the input, output, and power as shown on the wiring
label. For AC current input, install a jumper wire be-
tween terminals 7 and 8.
Do not run Class 2 signal wires adjacent to or in the
same conduit as power wires.
Calibration
1.
Apply the appropriate input for the low end of the scale.
2.
Adjust the ZERO screw for the appropriate low end output.
3.
Apply the appropriate input for the high end of the scale.
4.
Adjust the SPAN screw for the appropriate high end output.
5.
Repeat as necessary.
