Terminal Arrangement and Wiring
GRT1-TS2P/TS2PK When using a 2-wire sensor, short-circuit the SHT terminals for that input.
Note If a 2-wire sensor is wired as shown below, the error in the accuracy will be
much greater when compared to the wiring method in the above figure. Wire
according to the above figure whenever possible.
GRT1-TS2T
Note If an input is not being used, an input error will occur and an over range error
and off-wire condition will be detected. Proceed in one of the following ways.
• Wire to unused terminals.
• Set a parameter with the Setting Tool so that input errors will not be
detected. (Refer to Disabling Input Error Detection on page 207.)

Cold Junction Compensator
Never touch or remove the cold
unction compensator. Doing so
may cause the temperature data to
be displayed incorrectly.
