Decimal 2
Select the decimal point location for process type input 2 data. This
prompt, in conjunction with the Range Low and Range High prompts,
allows you to format and limit units of measure for process 2.
• All prompts with units of measure related to input 2 will display in the
selected decimal format.
• This affects propbands, alarm set points, process set points, calibration
offsets, deadbands and ranges.
[dEC2] This prompt appears only if you have set input 2 [`In2] to a
process input, [Curr] or a thermocouple input set to [0-50] mV.

Range Low 2 and Range High 2
Select the low and high limits for input 2. These prompts limit the
adjustment range for the set points. The default values are the same as
the limits of the sensor you selected by setting the input 2 DIP switch and
selecting a value for Input 2 [`In2].
• Process inputs are scaled by these values. Range high is the value dis-
played when the maximum process signal is present at the input. Range
low is the value displayed when the minimum process signal is present
at the input.
Example: Set [`In2] to [4-20]mA.
Set [`rL2] to [`100].
Set [`rH2] to [`500].
A 4mA input will display [`100].
A 12mA input will display [`300].
A 20mA input will display [`500].
• The low and high values of each sensor type are listed on the specifica-
tions page of the Appendix.
• Choose between Fahrenheit and Celsius at the [`C_F] prompt in the
Global Menu.
[`rL2] [`rH2] These prompts appear only if the controller is equipped
with input 2 hardware and with Input 2 [`In2] not set to [``no] or
[`Ei2].
