UDC3500 Universal Digital Controller Product Manual
Parameter
Definition
TO MAN—MANUAL MODE, SAME OUTPUT
The controller will return to manual mode at the
same output level that it had before shed.
FSAFE—MANUAL MODE, FAILSAFE OUTPUT
The controller will return to manual mode at the
output value selected at Control prompt FAILSAFE.
TO AUTO—AUTOMATIC MODE, LAST SP
The controller will return to the automatic mode and
the last setpoint used before shed.
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—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—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.
