ATTENTION To cycle through the available local
setpoints and remote setpoint, press and hold in the
SP SP SP
Select Select Select
key. When the key is released, the
setpoint selection currently displayed will be the new
setpoint selection.
AUTO BIAS—Used for bumpless transfer when
transferring from local setpoint to remote setpoint.
Auto Bias calculates and adds a bias to remote
setpoint input each time a transfer is made. Available
for any analog input used as the RSP source and if
no tracking is selected.
ENABLE—Enables auto bias.
DISABLE—Disables auto bias.
SETPOINT TRACKING—The local setpoint can be
configured to track either PV or RSP as listed below.
Not configurable when Auto Bias is set.
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.
NO TRACKING—If local setpoint tracking is not
configured, the LSP will not be altered when transfer
from RSP to LSP is made.
PV—Local setpoint tracks the PV when in manual
mode.
RSP—Local setpoint tracks remote setpoint. When
the controller transfers out of remote setpoint, the
last value of the remote setpoint (RSP) is inserted
into the local setpoint.
POWER UP CONTROLLER MODE RECALL—This
selection determines which mode and setpoint the
controller will use for Loop 2 when the controller
restarts after a power loss.
MANUAL, LSP—At power-up, the controller will use
manual mode with the local setpoint displayed.
