CX-Integrator
Actual adjustments are made from the CX-Integrator.
Connect the six-dial resistance box to the input terminals.
Connect them to the input terminals for the required input from input 0 to 3.
CRT1-TS04P
(1) When connecting the six-dial resistance box, use a cable with the same
gauge as the one that will be used for operation.
(2) The personal computer (CX-Integrator) is connected through CompoNet
in the above diagram. If a CS1W-CRM21 or CJ1W-CRM21 Master Unit is
being used, it can be connected through the Master Unit using a periph-
eral bus connection to adjust the Temperature Input Unit.

Six-dial resistance box
Adjusting the Upper and Lower Limit Values
1. Set the resistance value on the six-dial resistance box equivalent to the
test value and properly wire the box to the input of the Temperature Input
Unit that is being adjusted.
2. If the correct resistance cannot be obtained, properly wire the digital mul-
timeter to the six-dial resistance box and measure the resistance.
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.
