Definition

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.

INITIATE LIMIT CYCLE TUNING— Contact closure starts the tuning process. The lower display shows TUNE ON. Opening the contact has no effect.

SETPOINT INITIALIZATION— Contact closure forces the setpoint to the current PV value. Opening the contact has no effect.

OUTPUT 1 TRACKS INPUT 2*— Contact closure allows Output 1 to track Input 2. (NOTE 1)

OUTPUT 2 TRACKS INPUT 2*— Contact closure allows Output 2 to track Input 2.

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 REMOTE SETPOINT— Contact closure selects the Remote setpoint.

EXTERNAL RESET FEEDBACK— Contact closure allows Input 2 to override the internal reset value.

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)

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)

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.

RESET TOTALIZER— Contact closure transition resets the accumulated totalizer value. Opening the switch has no effect.
