The controller will return to manual mode at the
output value selected at Control prompt FAILSAFE.
TO AUTO
TO AUTO—AUTOMATIC MODE, LAST SP
The controller will return to the automatic mode and
the last setpoint used before shed.
SHED SP
SHED SETPOINT RECALL—The instrument will
control to the selected Setpoint following a Shed.
(controller switches from using CSP to LSP)
ATTENTION If SHEDENAB is configured for
DISABLE, then this prompt will not be configurable.
NOTE: if a RSP is the current setpoint, a CSP
override will not be used. CSP overrides local
setpoint only.
TO LSP
TO LSP—When a Shed occurs, the controller
switches from slave to monitor mode and uses the
last local setpoint prior to the slave mode. The CSP
value is disregarded on Shed.
TO CSP
TO CSP—When a SHED timeout occurs, the
controller switches from slave to monitor mode and
uses the local setpoint that is set equal to the CSP
value.
