The Sup Kc and Exh Kc items change the gain control
coefficient. When this item is entered, a value for Sup Kc
or Exh Kc is indicated on the display. If the controller is not
controlling correctly (hunting, oscillating, or controlling
slowly) the Sup Kc or Exh Kc control coefficient may need
adjusting. Decreasing Sup Kc or Exh Kc will slow the
control system down making it more stable.
The Sup Ti and Exh Ti items change the integral control
coefficient. When this item is entered, a value for Sup Ti or
Exh Ti is indicated on the display. If the controller is not
controlling correctly, the unit may have an inappropriate
Sup Ti or Exh Ti control coefficient. Increasing Sup Ti or
Exh Ti will slow the control system down making it more
stable.
Sup Kc = 0 to
10,000
Exh Kc = 0 to

Sup Ti = 0 to

The range of
values is very
large. Poor control
may occur if values
are more than twice
or less than 1/2 the
default value
Sup Kc = 75
Exh Kc =75
Sup Ti = 150
Exh Ti = 150
WARNING
The Sup Kc, Exh Kc, Sup Ti and Exh Ti items provide you
with the ability to manually change the PI control loop
variables. DO NOT CHANGE THESE VALUES UNLESS
YOU HAVE A THOROUGH UNDERSTANDING OF PID
CONTROL LOOPS. CONTACT TSI FOR ASSISTANCE
PRIOR TO CHANGING ANY VALUES. Incorrectly
changing a value will result in poor or non-existent control.
Suggestion: Before changing Sup Kc, Exh Kc, Sup Ti or
Exh Ti, change the Speed or adjust the Sensitivity to try
to eliminate the problem.
