Millivolt signals are not counted by the PIM unless a suitable preamplifier is used to boost the signal to a level that can be detected by the PIM circuitry. l Current Pedestal signaling is not directly supported by PIM circuitry.

SP 1 SETPOINT 1—Represents the value of the setpoint in
units of PV for Loop 1.
PV 2 PROCESS VARIABLE 2—Represents the value of the
process variable for Loop 2.
DEV 2 DEVIATION 2 (PROCESS VARIABLE MINUS
SETPOINT)—Represents –100 to +100% of the
selected PV span for Loop 2.
See Example at DEV 1.
OUT 2 OUTPUT 2—Represents the displayed controller output
in percent (%) for Loop 2.
SP 2 SETPOINT 2—Represents the value of the setpoint in
units of PV for Loop 2.
4 mA 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 for all selections above
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 for: Input 1, Input 2,
Process Variable, Deviation,* and Setpoint.
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 output. Zero
deviation will produce a center scale (12 mA) output. A
negative deviation equal in magnitude to the Auxiliary
Output High Value will produce a low end (4 mA) output.
