Definition
LOW VAL
Low Scale Value
within the range of
the selected
variable to
represent the
minimun output (0
or 4 mA)
AUXILIARY OUTPUT LOW SCALING FACTOR— This is a value
in engineering units used to represent all AUX OUT parameters
except Output.
For Output, this is a value in percent and can be any value
between –5 % and +105 %. However, keep in mind that relay
output types can only be scaled 0 % to 100 %.
HIGH VAL
High Scale Value
within the range of
the selected
variable to
represent the
maximum output
(20 mA)
AUXILIARY OUTPUT HIGH SCALING FACTOR— This is a value
in engineering units used to represent all AUX OUT parameters
except Output.
For Output, this is a value in percent and can be any value
between –5 % and +105 %. However, keep in mind that relay
output types can only be scaled 0 % to 100 %.
DIG INP1 DIGITAL INPUT 1 SELECTIONS—All selections are available for
Input 1. The controller returns to its original state when contact
opens, except when overruled by the keyboard.
NONE
NO DIGITAL INPUT SELECTIONS
TO MAN
TO MANUAL—Contact closure puts the affected loop into manual
mode. Contact open returns controller to former mode.
TO LSP
TO LOCAL SETPOINT—When a remote setpoint is configured,
contact closure puts the controller into local setpoint 1. When
contact opens, the controller returns to former operation—local or
remote setpoint—unless SP Select key is pressed while digital
input is active. If this happens, the controller will stay in the local
setpoint mode when contact opens.
TO 2SP
TO LOCAL SETPOINT TWO—Contact closure puts the controller
into local setpoint 2.
TO 3SP
TO LOCAL SETPOINT THREE—Contact closure puts the
controller into local setpoint 3.
TO DIR
TO DIRECT ACTION—Contact closure selects direct controller
action.
TO HOLD
TO HOLD—Contact closure suspends Setpoint Program or
Setpoint Ramp. When contact reopens, the controller starts from
the Hold point of the Ramp/Program unless the Ramp/Program
was not previously started via the

This selection applies to either loop.
TO PID2
TO PID2—Contact closure selects PID Set 2.
PV 2IN
PV=INPUT 2—Contact closure selects PV = Input 2.
RERUN
RERUN--Allows the Setpoint Programmer to be reset to the initial
segment of its current cycle, unit stays in previous mode.
