About this task

When you configure the HMS1655 to use any of the secondary analog outputs in PID mode, the constants that determine the performance and characteristics of the closed-loop control scheme are specified with the corresponding option on the PID Loop Setup menu.

Procedure

  1. To specify the proportional, integral, and derivative constants used by the closed-loop control scheme for the corresponding analog output, click one of the secondary PID loops from the PID Loop Setup menu to open the PID Loop x Settings configuration popup menu.
  2. You can adjust the three dimensionless PID constants from 0 to 100 with the three sliders on the configuration screen.
  3. See the Alarms Setup menu and the configuration of the alarm resources on the HMS1655 for more information.
