Connect the device that requires adjustment.
To make the upper/lower limit adjustment, connect
a six-dial resistance box to the Temperature Input
Terminal that is being adjusted.
Turn ON the power to the associated system

Note The only sensors that can be adjusted are ones that operate while the power
supply is ON. When adjusting for sensors that are not presently in use,
change the input type setting and perform the adjustment procedure from the
beginning of the flowchart.
The following paragraphs explain how to connect the devices that must be
connected to the DRT2-TS04T for user adjustment. Wire the following devices
properly when adjusting the DRT2-TS04T.
■ Six-dial Resistance Box and Precision Digital Multimeter
Used to make adjustments at the upper limit and lower limit.
Prepare device that can provide accurate resistance values for measurement.
Use a precision digital multimeter that can measure the resistance values and
indicate when the six-dial resistance box is not producing an accurate resis-
tance.
■ DeviceNet Configurator (Version 2.40 or Higher)
The actual adjustment operations are performed with the Configurator. Check
the version of the Configurator, because the DRT2-TS04P cannot be adjusted
with an old version.
Refer to the DeviceNet Configurator Operation Manual for details on the Con-
figurator.
