9.2 Controller Accuracies, and Tolerances

Refer to the Centurion Configurable Controller Specification Sheet for a detailed breakdown of specifications.

9.3 Restrictions on Numeric Values in Gage and PID Monitor Screens

Due to a combination of the limited space and the spirit of the design objectives, there are certain restrictions imposed upon the formatted size of numbers in C3-3 Display screens.

●Positive numbers with no decimals can be displayed with up to four digits.

●Negative numbers are limited to three digits.

●Numbers of either sign with a decimal place are limited to three digits.

●Numbers with more than two decimal places will not be displayed at all, but will be replaced with dashes.

If a number with decimals is larger than the imposed limits, the display algorithm will attempt to adjust the precision so as to display as many of the most significant digits as possible.

9.4 Set Up Sheet

Refer to The Centurion Configuration Worksheet for a detailed workbook to document field changes to configuration parameters.
