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