TO Aout 
AUTOMATIC OUTPUT—Contact closure sends 
output to the value set at Control prompt AUTO OUT 
when the controller is in the Automatic mode. 
Reopening the contact returns the controller to the 
normal output. 
 ATTENTION  Does not apply to Three Position 
Step Control. 
 
TIMER 
TIMER—Contact closure starts timer, if enabled. 
Reopening the switch has no effect. 
 
AM STA 
TO AUTO/MANUAL STATION—Contact closure 
causes the control loop to perform as follows: 
  PV = Input 2 
  Action = Direct 
  Control algorithm = PD+MR 
  PID SET = 2 
  SP = LSP 2 
 
TO TUNE 
INITIATE LIMIT CYCLE TUNING—Contact closure 
starts the tuning process. The lower display shows 
TUNE ON. Opening the contact has no effect. 
 
SP Init 
SETPOINT INITIALIZATION—Contact closure 
forces the setpoint to the current PV value. Opening 
the contact has no effect. 
 
TRACK 
OUTPUT TRACKS INPUT 2—Contact closure 
allows Output to track Input 2. While the switch is 
open, the output is in accordance with its pre-
defined functionality. When the switch is closed, the 
output value (in percent) will track the Input 2 
percent of range value. When the switch is 
reopened, the output will start at this last output 
value and normal PID action will then take over 
control. The transfer is bumpless. 
 
TO RSP 
TO REMOTE SETPOINT—Contact closure selects 
the Remote setpoint. 
 
RST FB 
EXTERNAL RESET FEEDBACK—Contact closure 
allows Input 2 to override the internal reset value. 
 
To PURGE 
TO PURGE—Contact closure forces the loop to 
Manual mode with the output set to the Output High 
Limit configuration. MAN lights and the Output value 
is shown on the lower display. Opening the switch 
has no effect.  
 ATTENTION  Does not apply to Three Position 
Step Control.
