Adjustment Device Connection Diagram
Connect the six-dial resistance box to the input terminals. In the following
examples, the devices are connected to input 1, but connect to the corre-
sponding terminals when adjusting inputs 2 to 4.
Note 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 (Configurator) is connected through DeviceNet in
the diagram above. If a CS1W-DRM21 or CJ1W-DRM21 Master Unit is be-
ing used, the Configurator can also be connected through the Master Unit
using a peripheral bus connection. Refer to the Configurator Operation
Manual for details.

Adjusting the DRT2-TS04P's 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
Terminal 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 Configurator to the DeviceNet network and go online.
4. Upload settings to the Configurator.
5. Turn ON the power supplies of all Units, including the Temperature Input
Terminal to be adjusted. Wait approximately 30 minutes for the Tempera-
ture Input Terminal's internal temperature to stabilize.
6. Double-click the icon of the Temperature Input Terminal to be set in the
Main Window and open the Edit Device Parameters Window. (From the
Maintenance Mode Window, click the right mouse button over the Slave
icon and select Parameters and Edit.)
