REMOTE SETPOINT SOURCE—This selection
determines what your remote setpoint source will be when
toggled by the SETPOINT SELECT
key or Digital Input.
Not available for Cascade PID Loop.
RSP, Cascade, and SP3 are mutually exclusive.
NONE—No remote setpoint.
INP 2—Remote Setpoint is Input 2.
IN AL1—Remote Setpoint using Input 1 algorithm.
IN AL2—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
AUTOBIAS is 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.
Only available if no tracking is selected.
ENABLE—Enables auto bias.
DISABLE—Disables auto bias.
SP TRACK
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.
RSP RSP—Local setpoint tracks remote setpoint when in
automatic. When the controller transfers out of remote
setpoint, the last value of the remote setpoint (RSP) is
inserted into the 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. It applies to both loops.
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.
A RSP AUTOMATIC MODE, LAST RSP—At power-up, the
controller will use automatic mode with the last remote
setpoint used before power down displayed.
