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

the Remote setpoint.
RST FB
EXTERNAL RESET FEEDBACK —Contact closure
allows Input 2 to override the internal reset value.
To PURGE
