AUX OUT
(continued)
CB OUT2 CONTROL BLOCK OUTPUT2—Represents the
uncharacterized use of automatic control valve which
allows the characterizer to characterize the output on
Analog Output 1 and the Auxiliary Output to use the
uncharacterized output value as Output 2.
4mA VAL*
Low Scale Value within the
range of the selected
variable to represent 4 mA
AUXILIARY OUTPUT LOW SCALING FACTOR—Use a
value in engineering units to represent all AUX OUT
parameters except output.
Use value in percent (%) for output. (Output can be
between –5 % and +105 %.)
20mA VAL*
High Scale Value within the
range of the selected
variable to represent 20 mA
AUXILIARY OUTPUT HIGH SCALING FACTOR—Use a
value in engineering units to represent all AUX OUT
parameters except output.
Use a value in percent (%) for Output. (Output can be
between –5 % and +105 %.)
*When Deviation is selected, only one operating parameter will be entered. This value represents the deviation level
that will produce 20 mA (100 %) output. Zero deviation will produce a center scale (12 mA or 50 %) output. A
negative deviation equal in magnitude to the auxiliary output high value will produce a low end (4 mA or 0 %) output.
DIG IN 1
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.
ATTENTION
When the controller is configured for either
Cascade or Two-Loop control, then digital input #1
operates only on Loop 1 and digital input #2 operates only
on Loop 2.
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
SETPOINT 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.
