REMOTE SETPOINT SOURCE—This selection
determines what your remote setpoint source will be when
toggled by the SETPOINT SELECT
or Digital Input.
NONE—No remote setpoint,
INPUT 2—Remote Setpoint is Input 2.
INPUT ALGORITHM 1—Remote Setpoint using Input 1
algorithm.
INPUT ALGORITHM 2—Remote Setpoint using Input 2
algorithm.
INP 3—Remote Setpoint is Input 3.
ATTENTION
To cycle through the available local
setpoints and remote setpoint, press and hold in the
[SETPOINT SELECT] key. When the key is released, the
setpoint selection currently displayed will be the new
setpoint selection.
AUTOBIAS
ENABLE
DISABL
AUTO BIAS is used for bumpless transfer when
transferring from local setpoint to remote setpoint. Auto
Bias calculates and adds a bias to the remote setpoint
input each time a transfer is made. Available for any
analog input RSP source and if no tracking is selected.
ENABLE—Enables auto bias.
DISABLE—Disables auto bias.
SPTRACK
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.
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 mode.
RSP 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.
SP HiLIM
0 to 100 % of span input in
engineering units with
decimal place
SETPOINT HIGH LIMIT*—This selection prevents the
local and remote setpoints from going above the value
selected here. The setting must be equal or less than the
upper range of the inputs.
SP LoLIM
0 to 100 % of span input in
engineering units with
decimal place
SETPOINT LOW LIMIT*—This selection prevents the
local and remote setpoints from going below the value
selected here. The setting must be equal or greater than
the lower range of the inputs.
ACTION
CONTROL OUTPUT DIRECTION—Select direct or
reverse acting control.
DIRECT DIRECT ACTING CONTROL—The controller's output
increases as the process variable increases.
