Definition

SHED CONTROLLER MODE AND OUTPUT LEVEL— Determines the mode of local control you want when the controller is shed from the communications link.

Note: If COMSTATE = MODBUS or MB3K and if SHEDENAB=DISABLE, this prompt will not be configurable.

LAST— SAME MODE AND OUTPUT— The controller will return to the same mode (manual or automatic) at the same output level that it had before shed.

ToAUTO— AUTOMATIC MODE, LAST SP— The controller will return to the automatic mode and the last setpoint used before shed.

FSAFE— MANUAL MODE, FAILSAFE OUTPUT— The controller will return to manual mode at the output value selected at Control prompt FAILSAFE.

TO MAN— MANUAL MODE, SAME OUTPUT— The controller will return to manual mode at the same output level that it had before shed.

SHED SETPOINT RECALL

Note: If COMSTATE = MODBUS or MOD3K and if SHEDENAB=DISABLE, this prompt will not be configurable.

TO LSP— Controller will use last local or remote setpoint used.

TO CSP— When in “slave” mode, the controller will store the last host computer setpoint and use it at the Local setpoint. When in “monitor” mode, the controller will shed to the last UDC Local or Remote setpoint used, and the LSP is unchanged.

COMMUNICATION UNITS— This selection determines how the controller values are expressed (on both loops) during communications.
