1.2 Description of SmartCal Positioner.
The SmartCal Smart Valve Positioner is an electro-
pneumatic servo system that continuously controls
the position of a valve based on a 4 to 20 mA input
signal. The SmartCal is an instrument that derives its
power directly from a control systems current loop.
The instrument senses valve position via a non-
contact Hall Effect sensor and controls valve position
through a current to pressure transducer.
The SmartCal is available in two versions, HART®
and non-HART. The non-HART version allows
calibration of the instrument through an on board
keypad. The HART® version allows calibration and
access to on-line diagnostic information via
Rosemount 375/475 hand-held terminal or through
software.
The positioner has a local liquid crystal display which
indicates valve position and set-point in percentage
of full span. It also indicates whether the positioner
is in calibration mode.
The SmartCal has the capability to monitor operation. If a failure condition occurs,
an error message is displayed on the local liquid crystal display.
There are several accessories that can be integrally supplied with the SmartCal.
Among these are a 4 to 20 mA analog output, and a set of hermetically sealed non-
contact limit switches.

1.3 Principle of Operation
Unlike conventional positioners, the SmartCal Smart Positioner feeds back
valve position without the need for linkages, levers, or rotary and linear seals.
Position sensing is performed totally by non-contacting means, permitting use
of advanced control strategies where knowledge of valve position is used in
predictive and other algorithms. By the integration of multiple components into
a singular, cost efficient unit, microprocessor-based intelligence can now be
used to implement advanced functions such as early warning diagnostics.
The SmartCal positioner provides intelligence for the control valve through a
microprocessor-based diagnostic system utilizing HART®or Foundation
Fieldbus protocols. Accurate measurement of valve stem position, input signal,
actuator pressure and travel time can be recorded during normal operation,
thereby providing information for control valve signature generation.

1.4 Special Features
Non-Contact Position Feedback
To provide consistently accurate performance information, all linkages, levers
and connecting rods, from the positioner to the control valve have been
eliminated from the design. Valve position sensing is performed totally by non-
contact means based upon characterization of magnetic flux strength as a
function of position.

Remote Position Control
Since valve position feedback to the SmartCal positioner
is accomplished by non-contact means, the SmartCal has
the unique ability to be mounted remotely (up to a distance
of 50 feet, optionally 150 feet) from the device it is
controlling. The remote position sensor also has the ability
to work over a wider temperature range, from -40C to
125C (-40F to 257F). In the event the control valve is
located in a high vibration, high temperature or extremely
corrosive environment, the non-contact position feedback
feature allows for isolated placement of the positioner.
Local Graphic LCD
The SmartCal positioner is supplied with a digital
communication interface (FF, HART
®
) or a 3-button keypad interface. Both versions are furnished
with a graphic LCD, and allow for automated calibration of the
positioner. The local LCD provides a multitude of onsite diagnostic
information. The LCD shows input current, set-point and current
position. The values displayed range from 0.0% to 100.0%. Displayed
resolution is in 0.1% increments, however, internal calculations are
maintained at higher precision.
On-Board Sensors
The SmartCal positioner has the capability to monitor its operation. If an error or failure condition
occurs, it will be displayed on the local LCD, or if the positioner is supplied with a HART
®
interface,
the error codes will be displayed on a hand held terminal or a PC maintenance station. Note: Error
codes are denoted on a label affixed to the LCD flip-up protective cover.
Local Keypad
The positioner is provided with a ruggedized 3-button keypad. The keypad can be
used for zero and span adjustments, as well as valve characterization and gain
adjustments.
Intelligent Calibration (HART
®
Protocol)
The SmartCal positioner responds to HART
®
commands for seeking the “valve
closed” position and assigns an instrument signal of 4 mA to this position. The
counterpart of the operation for a full open state is implemented next by setting the span value.
Action reversal is also configured. Additionally, provisions are made for altering internal servo
loop tuning via the HART
®
link. In this manner, positioner performance may be optimized with a
wide combination of valves and actuators.
Negligible Bleed
Designed to consume the least possible amount of control air at steady state, the SmartCal
positioner can greatly reduce the air consumption of your process and reduce the demand on
instrument air compressors. To increase reliability, the SmartCal employs a patented lapped spool
and floating sleeve design. This balanced construction relies on an air bearing which eliminates
any metal to metal contact.

3.3 Mounting Positioner on a Linear Actuator
Step 1. Mount the magnet assembly to the stem of the actuator. A coupler block normally
is needed to extend the magnet assembly outside the yoke area and into the sensing
range of the magnetic pick-up unit.
Step 2. Fasten the mounting bracket to the actuator.
Step 3. Mount the positioner to the mounting bracket. The positioner should be mounted
so the magnetic pick-up unit of the positioner is centered between the limits of the
magnetic assembly’s stroke. After mounting the positioner, the magnet assembly should
be within 1/8” [3.2 mm] from the back of the positioner (1/16” [1.6 mm] is ideal), (See
Figure 3-5)
Figure 3-5
Note: For Fisher actuators model 657 & 667 sizes 34 thru 70, a slotted mounting kit
design can be supplied. This will allow the user to easily center the positioner sensor
between the limits of the magnet assembly’s stroke. Other mounting kits are available
upon request.

3.5 Pneumatic Connection
Single Acting Actuator (Spring Return):
For single acting actuators Outlet Port 2 is to be plugged. Outlet Port 1 is to be piped to
the actuator inlet port that acts against the spring. (increasing set-point signal causes
pressure to increase in Outlet Port 1 of the positioner).
Double Acting Actuator (Double Return):
For double acting actuators Outlet Port 2 is piped to drive the actuator towards the fail
position. Outlet Port 1 is piped to drive the actuator away from the fail position. (increasing
set-point signal causes pressure to increase in Outlet Port 1 of the positioner and pressure
to decrease in Outlet Port 2 of the positioner).
Note: Air supply to the positioner must be clean, dry, oil free instrument air per ISA-S7.3.
Maximum supply pressure is 120 psi. All pneumatic connections are 1/4” NPT or 1/4 BSP.
1. Single Acting/Spring Return (Plug Outlet Port 2) increasing signal causes pressure to
increase in Outlet Port 1.
2. Double Acting/Double Return (Pipe Outlet Port 2 to drive actuator towards the
desired failure direction) increasing signal causes pressure to decrease in Outlet Port
2 and pressure to increase in Outlet Port 1.
Notes:
1. On loss of electrical power Outlet Port 1 has zero pressure and Outlet Port 2 has full
pressure.

3.6 Electrical Connection
A) The certification applies to equipment without cable glands. When mounting the
enclosure in the hazardous areas, only suitably certified cable glands and blanking
elements must be used to maintain ingress protection of IP66.
B) All unused cable entries must be plugged with suitably certified plugs that can
maintain an ingress protection level of IP66.
C) The positioner, switches, sensors and coils shall be electrically connected suitable
to the rated data via a certified isolating interface/zener barrier placed outside the
hazardous areas.
D) For ambient temperatures below -10~C and above +60~C, use field wiring suitable
for both minimum and maximum ambient temperatures.
E) Electromagnetic compatibility (emissions and susceptibility) is guaranteed only if
the unit and all cables are shielded and grounded as illustrated in Appendix F.
1. Remove positioner cover.
2. Locate terminal strip and carefully disconnect (slide
off).
3. Connect the 4 to 20 mA loop signal to terminal points
marked (+) and (-). See figure 3-10 for a wiring
schematic.
4. If the positioner was ordered with an analog output,
connect output wiring to terminal points 5 & 6,
(polarities shown on figure 3-10). The 4-20mA analog
output is of the current sink type therefore it requires
a suitable external DC power supply (24VDC
nominal).
5. If the positioner was ordered with switches, connect to the switches at terminal points
1 thru 4, as shown in Figure 3-10.
6. After all connections have been made reconnect the terminal strip and replace
positioner cover.
