Adjusting the Upper and Lower Limit Values
1. Set the wiring for adjusting the upper and lower limits. If connecting the
precision digital multimeter (DMM), use a ferrule for two wires.
2. Check the sensor and input type being used.
When using an R, S, B, E, or W sensor, use a compensating conductor for a K
thermocouple. In addition, when using an R, S, or B sensor, set the input type
to K (0.0 to 500.0 ° C). When using an E or W sensor, set the input type to K
( − 200 to 1,300 ° C).
3. Connect the CX-Integrator to the CompoNet network and go online.
4. Upload settings to the CX-Integrator.
5. Turn ON the power supplies of all Units, including the Temperature Input
Unit to be adjusted. Wait approximately 30 minutes for the Temperature In-
put Unit's internal temperature to stabilize.
6. Double-click the icon of the Temperature Input Unit to be set in the Network
Configuration Window or right-click the icon and select Parameters - Edit.
The Configuration Window will be displayed.
7. Click the tab for the input that will be adjusted and click the Adjustment
Button.
