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.

Installation on Actuator (continued)

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

environment 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

temperature range.

Illustration #3: Mounting Assembly

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 information on

pneumatic connections.

4. This product comes shipped with conduit covers in the conduit

entries 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.

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.

Pneumatic Hookup Procedures

Prior to connecting the supply air to the spool valve, flush the system to remove any debris or contaminates. Galva-

nized pipe can easily flake and contaminate the system and therefore is not recommended. A 40 micron point of use

filter at every device is recommended.

4-Way Spool Valves

The TopWorx spool valve is a 5 port, 4-way valve driven by an internally mounted pilot. The spool valve supply port

and work ports are marked as follows:

***Never Plug, Block or Restrict Port 5***

Always install vents

or speed controls Supply

Always install vents

or speed controls

Highly Recommended

TopWorx highly recommends Locktite 567 brand thread

sealant. Do not use a hard setting pipe compound. If Teflon

thread seal tape is used, start the wrap on the second

thread from the leading thread of the fitting. This will pre-

vent tape shreds from contaminating the spool valve seals.

Breathers (AL-M31) should be installed in the exhaust

ports to keep debris from falling into the spool valve and

damaging the seals. This must be addressed prior to instal-

lation, or storage.

A flow control may be used in Port 3, but should NEVER

BE USED in Port 5. Any blockage or restriction may cause

an internal pressure build-up inside the enclosure and pose

a safety issue.

Electrical / FF Connections

The FOUNDATION Fieldbus Sensor Communications Module (SCM-FF) combines integral switch relays for position

sensing with FOUNDATION Fieldbus communications and pilot valve output drivers.

Pilot Valve Wiring

Single Pilot Valve

· The Orange (or Red) lead is terminated on V1+. (+ = Orange)

· The Black lead is terminated on V1-. (- = Black)

Dual Pilot Valve

· The open valve wiring to the V1 terminal (+ = Orange)

· The close valve wiring to the V2 terminal (- = Black)

FOUNDATION Fieldbus Wiring

The Fieldbus Segment Wiring is connected to the FF Terminals on the SCM. These terminals are NOT polarity

sensitive.

It is strongly recommended that FF wiring leads are not daisy-chained together and each drop provides

short-circuit protection.

Calibration of Target / Feedback

Calibration of the FOUNDATION Fieldbus SCM-FF

Never perform calibration procedure unless area is known to be safe.

· For Intrinsically Safe models, unit must be wired in accordance with Control Drawing S-K088A, or I.S.

components may be damaged.

· For standard explosion-proof models: The OPEN and CLOSED limit switches encapsulated within the

SCM-FF may be calibrated using a DC power supply set between 9-32V, or calibrated once connected

to the Fieldbus network.

Step 1

Connect the power supply, or Fieldbus wires, to the FF terminals. The terminals are not polarity sensitive.

With power applied to the FF terminals, the valve may be manually stroked using the Calibration Switch on

the SCM-FF.

Step 2

Place calibration switch to the CLOSE position. Valve should move to CLOSE position. If it does not, consult

troubleshooting section of page 11.

Step 3

Disengage the bottom Cam from the splined hub and rotate the bottom Cam clockwise until the Red LED

lights. Release the Cam to re-engage the splined hub.

Step 4

Slide the calibration switch to the OPEN position. Valve should move to OPEN position. If it does not,

consult troubleshooting section on page 11.

Step 5

Disengage the top Cam from the splined hub and rotate the top Cam counter-clockwise until the Green

LED lights. Release the Cam to re-engage the splined hub.

Step 6

Cycle the valve CLOSED and OPEN a few times using the calibration switch to verify both limit switches are

maintaining their set points.

Step 7

Place calibration switch in the FF position. If using a power supply to calibrate, disconnect leads to the

supply, and connect the Fieldbus loop when ready to put into service.

Step 8

Manipulate the transducer parameters via the control system as necessary for desired mode of operation.

NOTE: If using a reverse acting actuator, re-calibrate switches using Steps 3-6, but rotate counter-clockwise

for close and clockwise for open. Reverse Action must be set in the Transducer Block (see “Transducer

Block Initialization, Single-Dual Action”).

Section 2: Operation

This section of the manual provides operational information for configuring the SCM-FF device on the

FOUNDATION Fieldbus Host Control System. This section includes both required Control Configuration and

optional Monitoring Configuration information.

Control Configuration (Required)

The TopWorx FOUNDATION Fieldbus products should be configured for operation using a single Discrete

Output (DO) Function Block with Channel Parameter assignment of 5. This module configuration will

provide a multi-value DO Block that will fully control a single or a dual output device. The Readback_D

parameter will provide actual valve position based on the Open / Closed Limit Switches in the device.

Discrete Input (DI) Blocks are neither required nor desired for feedback function.

The values of these parameters are as follows:

Figure 4

NOTE: TopWorx has pre-configured modules and faceplates available for DeltaV control systems.

Contact the TopWorx factory or www.topworx.com for more information.

The Transducer Block is shipped from the factory in the OOS (Out of Service) Mode to allow field

installation/testing using the SCM calibration switch. Once the installation and the configuration above

are complete, The Transducer Block must be placed in the AUTO (Automatic) Mode for device

operation.

Alarm Configuration (Optional)

Discrete Input (DI) Block may be configured for monitoring internal Device Alarms within the Control Strategy

of the Host System.

The Internal Device Alarms can be monitored using a Discrete Input (DI) Block with the Channel Parameter

assignment of 13. All alarms that are activated (checked in the Transducer Block) can be read by this single

DI block in a masked fashion. See Appendix C for Transducer Block parameter settings.

Multiple active alarms are depicted by a HEX value representing the sum of all active alarms OUT_D Val-

ues. For example, a device with a Cycle Count Alarm and a Time to Close Alarm both active would have an

OUT_D Value of 0x05.
