AM STA TO AUTO/MANUAL STATION—Contact closure causes
the loop to perform as follows:
PV = Input 2
Action = Direct
Control algorithm = PD+MR
PID SET = 2
SP = LSP 2
This selection is only available on Loop 1.
ToTUNE INITIATE LIMIT CYCLE TUNING—Contact closure starts
the tuning process. The lower display shows TUNE ON.
Opening the contact has no effect.
SPinit SETPOINT INITIALIZATION—Contact closure forces the
setpoint to the current PV value. Opening the contact has
no effect.
TRACK1 OUTPUT 1 TRACKS INPUT 2*—Contact closure allows
Output 1 to track Input 2. (NOTE 1)
TRACK2 OUTPUT 2 TRACKS INPUT 2*—Contact closure allows
Output 2 to track Input 2.
ToOUT2 OUTPUT 2 OVERRIDES OUTPUT 1—Contact closure
allows physical Output 1 to be a copy of Output 2. When
contact is released, Loop 1 output will switch back to
normal PID controller action starting with the last output
value. (NOTE 1)
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.
ToPURG 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.
(NOTE 1)
LoFIRE LOW FIRE—Contact closure forces the loop to Manual
mode with the output set to the Output Low Limit
configuration. MAN lights and the Output value is shown
on the lower display. Opening the switch has no effect.
(NOTE 1)
MAN LT MANUAL LATCHING—Contact closure transition forces
the loop to Manual mode. Opening the switch has no
effect. If the MANUAL/AUTO
key is pressed while the
switch is closed, the loop will return to Automatic mode.
REStot RESET TOTALIZER—Contact closure transition resets
the accumulated totalizer value. Opening the switch has
no effect.
