UDC 3300 Controller Product Manual

You can use two sets of tuning constants for single output types and
2-loop or cascade control, and choose the way they are to be switched.
(Does not apply for Duplex control.)

The sets can be:

• keyboard selected,
• automatically switched when a predetermined process variable value

is reached,

• automatically switched when a predetermined setpoint value is

reached.

The following procedures show you how to:

• select two sets or gain scheduling,
• set the switch-over value,
• set tuning constant value for each set, and
• switch between two sets via the keyboard (without automatic

switchover)

The procedure in Table 5-16 tells you how to select two sets or gain
scheduling.
