Lower/Display key until you see PID SET1
or PID SET2 or PID SET3 or PID SET4 then press
or to switch between the sets.
Configure the values for:
Gain, Rate, Reset, Cycle Time
Gain #2, Rate #2, Reset #2, Cycle #2 Time
Gain #3, Rate #3, Reset #3, Cycle #3 Time

4PV SW
FOUR SETS PV AUTOMATIC SWITCHOVER—
When the process variable is GREATER than the
value set at prompt SW VALUE (Switchover Value),
the controller will use Gain, Rate, Reset, and Cycle
Time. The active PID SET can be read in the lower
display.
When the process variable is LESS than the value
set at prompt SW VALUE, the controller will use
Gain #2, Rate #2, Reset #2, and Cycle #2 Time. The
active PID SET can be read in the lower display.
Similarly, the controller switches between the other
PID sets based upon the values configured for SW
VAL 2 and SW VAL 3.
ATTENTION Other prompts affected: SW VALUE,
SW VAL 2 and SW VAL 3.
4SP SW
FOUR SETS SP AUTOMATIC SWITCHOVER—
When the setpoint is GREATER than the value set at
prompt SW VALUE (Switchover Value), the
controller will use Gain, Rate, Reset, and Cycle.
When the setpoint is LESS than the value set at
prompt SW VALUE, the controller will use Gain #2,
Rate #2, Reset #2, and Cycle #2.
Similarly, the controller switches between the other
PID sets based upon the values configured for SW
VAL 2 and SW VAL 3.
ATTENTION Other prompts affected: SW VALUE,
