Parameter Definition
BIAS
–9999 to 9999
(engineering units)
BIAS — used when input 2 operates as a remote
setpoint (prompt "REMOTE").
 Bias, together with ratio, establishes the correct
relationship between the remote setpoint and the
input 2 signal applied according to the formula:
REMOTE SETPOINT = IN2 VALUE (RATIO) + BIAS
NOTE: IN2 VALUE = Actual (engineering units)
 All values must be within configured setpoint high and
low limits.
 Input 2 must be enabled.
SP TRACK
SETPOINT TRACKING — the local setpoint can be
configured to track the remote setpoint as listed below:
NONE
 NO TRACKING — if local setpoint tracking is not
configured, the LSP will not be altered when transfer
from RSP to LSP is made.
RSP
 LSP (LOCAL SETPOINT) TRACKS RSP (REMOTE
SETPOINT) IN AUTO — if configured, when the
recorder transfers out of remote setpoint, the last
value of the remote setpoint (RSP) is inserted into the
local setpoint.
POWER UP
POWER UP CONTROLLER MODE RECALL — this
selection determines which mode and setpoint the
recorder will use when the it restarts after a power loss.
Select one from below:
MANUAL
 MANUAL, LSP — at power-up, the recorder will use
manual mode with the output value displayed.
A LSP
 AUTOMATIC, LOCAL SETPOINT — at power-up,
the recorder will return to the automatic mode and will
use the local setpoint for control.
A RSP
 AUTOMATIC, REMOTE SETPOINT — at power-up,
the recorder will return to the automatic mode and will
use the remote setpoint for control.
AM SP
 LAST MODE, LAST SETPOINT used before power
down.
AM LSP
 LAST MODE, LAST LOCAL SETPOINT on power
down.
SP HILIM
–999.0 to 9999.
input units
SETPOINT HIGH LIMIT* — this selection prevents the
local and remote setpoints from going above the value
selected here. The setting must be equal to or less than
the upper range of input 1 and input 2. Input 2, when
configured for remote setpoint, will be restricted to this
upper limit.
