5.3 Input Jumper Settings Must Match Input Type
Depending on the type of input, you might also have to change jumper settings. In 1ZC,
16C, 18C, and 25C controllers, the input jumpers must be set according to the type of
input jumper category.
• input jumper category 1 – temperature input (RTD or thermocouple) or low
voltage input (≤100 mV)
• input jumper category 2 – high voltage input (>100 mV)
• input jumper category 3 – current (milliamp) input
If you switch within a category, you do not have to change the jumper. For example, if
you change from RTD to thermocouple input, you do not have to change the jumper.
However, if you change from one category to another, you must set the input jumpers
accordingly. For example, if you change from RTD to current input, you must change the
jumper settings.
The input jumpers are set at the factory to match the type of input calibration
specified when the controller was ordered.

If the “calibrate all” option was
ordered, the input jumpers will be set for a temperature input. If you plan to use
the controller with an input that does not match the factory settings, you must set
the input jumpers correctly before any configuration parameters are configured.
The location of the 16C, 18C, and 25C input jumpers JMP01 and JMP 02 on the
processor board (board on the left when facing controller) is shown below.

To determine the type of input for which the controller in hand was calibrated (and for which the input
jumpers were set) at the factory, check the model number on the label on the controller. The meaning of
each character in the model number is in the installation manual supplied with the controller.
