ATTENTION To cycle through the available local
setpoints and remote setpoint, press and hold in the
SP/Select key. When the key is released, the
setpoint selection currently displayed will be the new
setpoint selection.
AUTOBIAS
AUTOBIAS—Used for bumpless transfer when
transferring from any local setpoint to remote
setpoint. This makes the RSP equal to the CSP by
adding, to the input used as the RSP source, a Bias
value. It is changed each time a transfer is made.
Available for any analog input used as the RSP
source.
DISABLE
ENABLE
DISABLE—Disables auto bias.
ENABLE—Enables auto bias.
SP TRACK
SETPOINT TRACKING—The local setpoint can be
configured to track either PV or RSP as listed below.
ATTENTION For selections other than NONE,
LSP is stored in nonvolatile memory only when there
is a mode change; i.e., when switching from RSP to
LSP or from Manual to Automatic. If power is lost,
then the current LSP value is also lost.
NONE
NO TRACKING—If local setpoint tracking is not
configured, the LSP will not be altered when transfer
from RSP to LSP is made.
PV
PV—Local setpoint tracks the PV when in manual.
RSP
RSP—Local setpoint is set equal to the remote
setpoint when a change is made from using remote
setpoint to any local setpoint.
PWR MODE
POWER UP CONTROLLER MODE RECALL—This
selection determines which mode and setpoint the
controller will use when the controller restarts after a
power loss.
MANUAL
MANUAL, LSP—At power-up, the controller will use
manual mode with the local setpoint displayed.
A LSP
AUTOMATIC MODE, LAST LSP—At power-up, the
controller will use automatic mode with the last local
setpoint used before power down displayed.
