Installation, Operation & Maintenance Manual
D-Series with HART Protocol Installation, Operation & Maintenance 502.969.8000
Installation on Actuator
Orientations, Normal and Reverse Acting
Normal acting is full CW when the process valve is closed and CCW when the process valve is open. Reverse acting
is full CW when the process valve is open and CCW when the process valve is closed.
90° indicator dome assemblies are design to accommodate any mounting arrangement and can be adjusted up to
9° off axis if needed. 45° indicator dome assemblies can only accommodate normal acting applications that are
mounted parallel ±9°. Consult your local distributor or factory representative for 45° reverse acting or mounted
perpendicular applications.
Illustration #1
The image to the left shows a Valvetop unit mounted
parallel to the process valve in the closed position.
The green arrow at the top shows the “normal acting”
direction of travel to open the valve. This is the standard
orientation and your unit unless otherwise specified will
be factory set to operate in this fashion.
Illustration #2
The image to the right shows a Valvetop mounted
perpendicular to the process valve in the closed
position. The green arrow at the top shows the
“normal acting” direction of travel to open the valve.
Notice that the indicator dome has been rotated 90°
compared to the unit above.

Mounting
TopWorx has numerous mounting bracket kits available to meet your specific application, whether rotary or linear.
Consult your local distributor or factory representative for ordering information. The illustration shows a direct Namur
mount on a quarter turn valve. Refer to your mounting kit documentation for specific mounting instructions.
Storage
Until conduit, conduit plugs, and any applicable spool valve port connections are properly installed, the ValveTop unit
will not support its IP/NEMA rating as the unit ships with temporary covers. Ensure that it is stored in a dry environ-
ment with a relative humidity range between 10%-95% and a temperature ranging from -40ºF (-40ºC) to 160ºF
(71ºC). Once properly installed, the temperature range listed on the nameplate will supersede this storage tempera-
ture range.

Installation Notes
1. Use caution not to allow undue axial (thrust) load on the shaft.
2. Cycle the valve a couple of times prior to final tightening of the
mounting kit hardware. This allows the shaft to self-center in the
pinion slot, or coupler. Refer to the dimensions and materials
section of this document for appropriate tightening torque.
3. Always use sound mechanical practices when torquing down
any hardware or making pneumatic connections. Refer to the
Integrated Pneumatic Control Valves section for detailed infor-
mation on pneumatic connections.
4. This product comes shipped with plastic plugs in the conduit en-
tries in an effort to protect the internal components from debris
during shipment and handling. It is the responsibility of the
receiving and/or installing personnel to provide
appropriate permanent sealing devices to prevent
the intrusion of debris, or moisture, when stored
outdoors or when installed.
5. It is the responsibility of the installer, or end user, to
install this product in accordance with the National
Electrical Code (NFPA 70) or any other national or
regional code defining proper practices.

Features and Specifications
4-20mA Position with HART Protocol
The 2-wire 4-20mA transmitter with HART will generate a nominal 4-20mA proportional to valve position output for full
-range actuation of the valve. The transmitter is capable of generating signals below 4mA and above 20mA if the po-
sition sensor indicates an out of range value. With the added HART digital communication capability, remote calibra-
tion and parameter configuration can be performed.
Features:
1) Single push button easy calibration eliminates zero/span calibration interaction in both clockwise and
counterclockwise actuator/valve rotation directions
2) Non-volatile memory of set points (set points remain after loss of power)
3) No internal backlash – direct shaft position feedback
4) No gear wear or mechanical binding
5) Position measurement range from 20 to 320 degrees. Factory set for 20 to 180 degrees operation in counter
clockwise rotation to open and 20 to 90 degrees operation in clockwise rotation to open applications
6) Advanced diagnostics includes detection of dead band, out of range indication
7) Transmitter PCB is potted and sealed from the environment
8) Selectable +/- 3% over and under travel capability or full linear
options set during calibration
HART Features:
1) Remote set point calibration
– Example: Using a handheld device for
calibration and monitoring
2) 4 to 20mA variable reading (PV)
3) Valve opening indication in percentage
4) Setting the range of the process variable
5) Monitoring and setting of alarms with advanced
diagnostics. Includes detection of deadband,
out of range indication
6) Selectable +/- 3% over and under travel
capability (rotary) or full linear options"

DEADBAND
INDICATION
Operation of the 4-20mA Current Position Transmitter
During run mode, the 4-20mA position transmitter will output 4-20mA for valve positions between and including the set points. In the rotary mode,
the module will provide an over or under travel correction if the valve position exceeds the high or low set point within +/-3% . In other words, the
output will be 4mA for +/-3% over and under travel on the low end and 20mA for +/-3% over and under travel on the high end. If the valve position
exceeds 3% of over travel, then values below 4mA or above 20mA will be output. In the linear mode, no under or over travel is compensated
for. The device can be set to either linear or rotary mode during calibration using the on board push button switch, or remotely using HART
communications.
Calibrating End Set Points Locally:
The 4-20 current transmitter can be used for any rotation range between 20 and 320 degrees**.
Option #1: +/- 3% Over and Under Travel at the Set End Points (Rotary):
1) As the shaft rotates, make sure the potentiometer is not rotating through its deadband area. The red dot located on the potentiometer should
not rotate past the area marked with red during the full rotation of the valve. If it does, reposition the shaft.
2) Apply power to unit (LED should be continuously on to indicate the unit has been calibrated or flashing the 4-1 code to indicate the unit has
not been calibrated)
3) Counter-clockwise calibration - Press the button greater than 0.5 seconds and less than 3 seconds if you are going to calibrate using a
counter-clockwise rotation from the 4mA position to the 20mA position. (LED will start flashing a 3-1 code indicating that calibration mode is
active and the unit is waiting to calibrate the 4ma position).
4) Clockwise calibration - Press the button greater than 3 seconds and less than 5.5 seconds if you are going to calibrate using a clockwise
rotation from the 4mA position to the 20mA position. (LED will start flashing a 3-2 code indicating that calibration mode is active and the unit
is waiting to calibrate the 4mA position).
5) Rotate valve to the desired position corresponding to 4mA. (This can be the open or closed position)
6) Press the button to capture the 4mA value (The LED will start flashing a 3-3 code indicating that the unit is waiting to calibrate the 20mA
position)
7) Rotate valve to the desired position corresponding to 20mA (This will be the position opposite of the position in step 3 or step 4)
8) Press the button to capture the 20mA value (The LED will turn on continuously)
Option #2: No Under and Over Travel at Set End Points (Full Linear):
1) As the shaft rotates, make sure the potentiometer is not rotating through its dead band area. The red dot located on the potentiometer should
not rotate past the area marked with red during the full rotation of the valve. If it does, reposition the shaft.
2) Apply power to unit (LED should be continuously on to indicate the unit has been calibrated or flashing the 4-1 code to indicate the unit has
not been calibrated)
3) Counter-clockwise calibration - Press the button greater than 5.5 seconds and less than 8 seconds if you are going to calibrate using a
counter-clockwise rotation from the 4mA position to the 20mA position. (LED will start flashing a 5-1 code indicating that calibration mode is
active and the unit is waiting to calibrate the 4mA position).
4) Clockwise calibration - Press the button greater than 8 seconds if you are going to calibrate using a clockwise rotation from the 4mA
position to the 20mA position. (LED will start flashing a 5-2 code indicating that calibration mode is active and the unit is waiting to calibrate
the 4mA position).
5) Rotate valve to the desired position corresponding to 4mA. (This can be the open or closed position)
6) Press the button to capture the 4mA value (The LED will start flashing a 3-3 code indicating that the unit is waiting to calibrate the 20mA
position)
7) Rotate valve to the desired position corresponding to 20mA (This will be the position opposite of the position in step 3 or step 4)
8) Press the button to capture the 20mA value (The LED will turn on continuously)
NOTE:**The potentiometer has been factory set for typical valve rotation ranges from 20 to 180 degrees in counter-clockwise rotation applications
from the 4mA position to the 20mA position and from valve rotation ranges from 20 to 90 degrees in clockwise rotation applications from the 4mA
position to the 20mA position. Please contact TopWorx for proper potentiometer set up for ranges greater than specified above.
