Definition

RUN—Contact closure starts a stopped SP Ramp or Program. Upper left character blinks “R”. Reopening the contact puts controller in HOLD mode.

This selection applies to either loop.

EXTERNAL SP PROGRAM RESET—Contact closure resets SP Program back to the beginning of the first segment in the program and places the program in the HOLD mode. Program cycle number is not affected. Reopening switch has no effect.

This selection applies to either loop.

ATTENTION Once the last segment of the setpoint program has timed out, the controller enters the mode of action specified in the configuration data and the program cannot be reset to the beginning of the first segment by digital input closure.

INHIBIT INTEGRAL (RESET)—Contact closure disables PID Integral (Reset) action.

MANUAL FAILSAFE OUTPUT—Controller goes to Manual mode, output goes to the Failsafe value.

ATTENTION This will cause a bump in the output when switching from Automatic to Manual. The switch back from Manual to Automatic is bumpless. When the switch is closed, the output can be adjusted from the keyboard.

KEYBOARD LOCKOUT—Contact closure disables all keys. Lower display shows LOCKED if a key is pressed.

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—Contact closure starts timer, if enabled. Reopening the switch has no effect.

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

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