The Dynisco PT46xDN is a full-featured, smart digital melt pressure transmitter, combining the reliability of this industry-standard Dynisco pressure transducer with the added flexibility of DeviceNet digital communications. The pressure sensing technology is the same as other Dynisco products, proven in such rugged applications such as Polymer Melt Processing applications. The rugged construction is ideal for harsh industrial environments.

The PT46xDN is easily integrated into any digital control system with a DeviceNet scanner. Continuous pressure data is available in real-time at a minimum digital resolution of 0.01% of full scale (14 bits). Monitoring and configuration of the PT46xDN is accomplished via the DeviceNet network using commerciallyavailable DeviceNet programming software.

The PT46xDN effectively combines the features of a melt pressure transducer, power regulator, alarm monitor, and DeviceNet digital signal conditioner into a single, cost-effective package. Wiring the PT46xDN transmitter is simple and fast by virtue of a standard DeviceNet 5 pin Micro-connector. The PT46xDN is powered directly by the DeviceNet bus eliminating the need for a separate power supply. Multiple DeviceNet Pressure Transmitters can be added to a network using a single DeviceNet Master scanner, making this

approach very attractive when an application calls for multiple pressure transmitters.

The mechanical system (filled assembly) consists of a lower diaphragm, a filled capillary tube, and an upper diaphragm with a strain gage. The filled assembly transmits pressure from the process to the strain gage diaphragm where it is converted to a digital signal. The filled assembly isolates the electronics from

5

GENERAL

the high process temperatures.

The lower diaphragm is the surface in contact with the media being measured. This diaphragm can be made from a choice of materials. The standard material is heat-treated 15-5 stainless steel with DyMaxTM coating. This has average corrosion and excellent abrasion resistance and is similar to 17-4 stainless steel. Other materials are also available such as Hastelloy C-276 which has excellent corrosion resistant properties (but is not good for abrasion). For other materials please consult the factory.

Behind the lower diaphragm is a capillary tube filled to the upper diaphragm. As the process pressure deflects the lower diaphragm, the fill is displaced through the capillary tube to deflect the upper diaphragm.

The upper diaphragm has a strain gage element in the configuration of a Wheatstone Bridge. The deflection of the upper diaphragm causes a change in the resistance of the strain gage and hence a change in the balance of the bridge. The amount of imbalance is directly proportional to the applied pressure. This completes the translation of pressure applied to the lower diaphragm into a usable electrical signal.

Functioning Principle of the Dynisco Filled AssemblyFunctioning Principle of the Dynisco Filled Assembly

Functioning Principle of the Dynisco Filled Assembly

The low level output signal from the bridge is amplified via an instrumentation amp circuit. The amplified signal then goes to the input of the analog-to-digital (A/D) converter.

The PT46xDN Transmitter supports Polled I/O Messaging to read “real-time” data. It does not support Cyclic I/O, Change of State (COS), or Bit-Strobe connections. The control system Master must be configured first 8-bit word (Byte 0) of the I/O Message Response as shown in Table 1. Note that the most significant 4 bits of the first byte are reserved for future use. The next 8-bit word (Byte 1) supplies transmitter status information, e.g. reading valid, electronics fault, etc. Further information on alarm and status bits is available in Section 7.4. The remaining 2 8-bit words (Bytes 2 & 3) represent the Pressure Value (PV).

When reading the PV, it is important to understand how the value is scaled by the Engineering Units parameter and the Unity Gain Reference (UGR) parameter.

The PV can be scaled to a variety of engineering units, e.g. counts, psi, bar, etc., by setting the Data Units parameter to the appropriate value as listed in Attribute #02 of Section 7.4.

When reporting the PV in any engineering unit other than counts, a decimal scale factor called the Unity Gain Reference (UGR) is used to convert PV to “real world” pressure. By employing the UGR, the I/O data is presented in a more efficient integer format rather than a floating point. The UGR is factory-set and cannot be changed.

To compute the actual pressure, the control system must simply divide the PV by the UGR (

Pressure = PV /

UGR

).

Do not remove the protective cap on the PT until ready to install.

Before mounting the PT, check mounting hole carefully. The PT must only be mounted in holes that satisfy the requirements below. A hole that does not satisfy these requirements can damage the Transmitter.

Insure the mounting hole is clear of any frozen polymer or debris and is machined to the proper dimensions.

For threaded PT transmitters coat the threads with a high temperature anti-seize grease or a suitable parting agent, this will help prevent the PT snout from sticking permanently in the mounting hole.

Install unit into the process connection. (Do NOT torque transmitter into the hole at this time!) Allow time for the transmitter snout temperature to equalize to the process temperature. This will help eliminate

thread galling and ease removal later. There should be NO pressure applied at this time.

Always use a torque wrench applied to the designated hexagon collar or mounting bolts while screwing the transmitter in and out. Do not apply the tool to the housing or housing/sensor connection.

After temperatures have equalized, apply proper torque as described in Section 3.20 of the Manual and tighten transmitter into mounting hole.

After the correct torque has been applied units with flexible capillary require the electronics to be mounted away from the process heat using mounting hardware, P/N 200941.

Make sure that the medium is in molten condition during transmitter removal. Removing the transmitter while the medium is in solidified condition can damage the sensor diaphragm.

When removing the PT, carefully clean the diaphragm of the transmitter with a soft cloth while the medium is still malleable.

20

INSTALLATION

Always remove the PT prior to cleaning the machine with abrasives or steel wire brushes. Also, do not clean the PT with hard objects, such as a screwdriver, a wire brush, etc. this will possibly damage the transmitter.

Before reinstalling the PT, ensure that the mounting hole is free from hardened plastic. A mounting hole cleaning tool kit is available to aid in removing of the material. (Dynisco Part Number 200100 for ½-20, 200101 for M18 and 200102 for M10 ports.) A gauge plug to check the hole is included in this kit.

The most common causes of transducer damage are: installation in improperly machined or plugged mounting holes and cold starts. The tip of the transducer consists of a stainless steel diaphragm that must be protected from severe abrasives, dents and scores.

Burn Hazard!Burn Hazard!

Burn Hazard!

The PT must be removed with the melt in the molten condition. The PT can be very hot

when removed. WEAR PROTECTIVE GLOVES!

Careful attention should be paid to correctly machine the mounting port. Failure to use the recommended mounting port may result in erroneous pressure measurement, difficult transducer removal, premature sensor failure, process fluid leaks, and personnel hazard. In applications involving high temperature operation and/or repeated thermal cycling a good high quality anti-seize compound should be applied to the threaded surfaces.

Dynisco offers a set of mounting hole-machining tools with all the necessary drills, taps, and reamers for the Dynisco standard ½-20UNF-2A and M18 and M10 mounting holes used in high temperature and plastics processing applications (Dynisco Part Numbers 200925, 200105 and 901949 respectively). Detailed instructions are sent with the machining kits. Copies of the instructions are available from Dynisco upon request.

When machining the hole pay careful attention to the concentricity between the threads and the 0.312/

0.314 diameter. Since the pressure seal is on the 45° seating surface, this surface should be examined for good finish, free from burrs, etc.

It is general good practice to check the mounting hole before installing the transducer. One procedure is to coat a gauge plug (Dynisco Part Number 200908 for the 1/2 –20 standard port, 435901 for the short tip 1/2 –20 version, 200960 for the M18), with Dykem machine bluing on surfaces below the thread. Insert the gauge plug into the mounting hole and rotate until surface binding is encountered. Remove and inspect. Bluing should only be scraped off of the 45° sealing chamfer. If bluing has been removed from other surfaces, the mounting hole has not been machined properly.

The PT46XDN can be readily connected to the DeviceNet bus using the optional connector and cable assembly or a customer-supplied connector and cable. It is important to adhere to proper DeviceNet wiring practices. The DeviceNet Technical Overview available from the Open DeviceNet Vendors Association (www.odva.org) provides additional information on DeviceNet physical layer topologies including cable types, trunk and drop lengths, and terminating resistors.

It is recommended that all wiring be validated using a media checker to identify potential media problems, e.g. shorts, opens, excessive cable length, and crossed connections.

When the transmitter is connected to the DeviceNet bus, it will perform an initialization sequence to establish communications with the Master.

1. Initially, the Device Status LED will flash red one time, and then will change to a steady green. At this point the Transmitter has passed its internal health check.

2. Simultaneously, the Network Status LED will flash green one time, then after a few seconds will continue to flash green.

3. At this point, the duplicate MAC ID check is complete, and the transmitter is waiting to be allocated to a Master.

4. If the Network status LED stays solid red, remove the connector and then reconnect. If the LED is still solid red, continue to section 6.2 Setting the Node Address and Baud Rate

After the baud rate and node address have been established, the device parameters are ready to be configured. The following configurable parameters are available (see Section 7.4 for more information):

1. Data Units (Attribute #02 / Default is “counts”)

The Pressure Value (PV) can be scaled to a variety of engineering units by configuring the Data units to digital counts, PSI, bar, kg/cm^2, MPa or % full scale.

2. Alarm and Warn Status Enable (Attribute #06 and #07 / Default is “disabled”)

The respective parameters must be set (i.e. enabled) if the master will use the alarm or warning bits in the I/O message.

3. Alarm Trip Point High and Low (Attribute #13 and #14)

These values (and the Hysteresis) define under what conditions the Alarm High and Low status bits are set in the I/O message.

4. Alarm Trip Point Hysteresis (Attribute #15)

This value (and the Alarm Trip Point High and Low values) define under what conditions the Alarm High and Low status bits are set in the I/O message.

5. Warning Trip Point High and Low (Attribute #17 and #18)

These values (and the Hysteresis) define under what conditions the Warn High and Low status bits are set in the I/O message.

6. Warning Trip Point Hysteresis (Attribute #19)

This value (and the Warn Trip Point High and Low values) define under what conditions the Warn High and Low status bits are set in the I/O message.

7. Set Zero Service (for zeroing effects of temperatures and mounting position)

Execute this service to zero the PV output. Refer to Section 7.3 for more information.

There is one manufacturer-specific service to start “SetZero” functionality. The service acts as a “tare” function by offsetting the current pressure value by the pressure value at the time the service is invoked. This is typically used to eliminate a zero shift which may occur at elevated temperature. The service code is 100

Installation and Removal Instructions

• DO NOT REMOVE PROTECTIVE CAP UNTIL READY TO INSTALL.

• PRIOR TO INITIAL INSTALLATION, VERIFY CORRECT MACHINING OF MOUNTING HOLE.

• WHEN REINSTALLING, MAKE SURE MOUNTING HOLE IS CLEAR OF DEBRIS OR HARDENED

PLASTIC.

• THE MEDIUM MUST BE IN MOLTEN CONDITION DURING TRANSDUCER REMOVAL. (Removing the transducer with the medium in a solidified condition can damage the sensor diaphragm.)

• ALWAYS REMOVE THE PT BEFORE CLEANING THE MACHINE WITH ABRASIVES OR STEEL WIRE BRUSHES, ETC.

• DO NOT CLEAN THE “SCREWED-IN” SECTION OF THE PT WITH HARD OBJECTS – THIS WILL DAMAGE THE PT.

• ALWAYS USE A TORQUE WRENCH APPLIED TO THE DESIGNATED HEXAGONAL COLLAR WHEN SCREWING THE PT IN AND OUT. DO NOT APPLY THE TOOL TO THE HOUSING OR HOUSING/ SENSOR CONNECTION.

• ELECTROSTATIC DISCHARGE MAY DAMAGE THE PT – TAKE ESD PRECAUTIONS.

Output Not at Zero 1) Preform Set Zero Service

Output is Negative at Zero Pressure 1) Process temperature has cooled down since last Set

Zero. Wait for process to fully heat up to operating temperature.

2) Transducer has lost its fill due to diaphragm damage or rupture.

Large Zero Shift when screwing 1) Check mounting hole for frozen polymer. in to mounting hole 2) Check transdcuer tip for damage

3) Check mounting hole for concentricity by using gauge plug in transducer cleaning tool kit (p/n 200100) to check for side loading of the transducer tip. Dykem bluing should only be rubbed off at the 45° sealing surface and threads. Rework hole to proper specifications.

4) Check mounting torque is within specifications.

No response to changes in 1) Check Port/Piping for blockage or solidified polymer applied pressure 2) Check Transducer tip for diaphragm damage, rupture or

missing

3) Check Flexible Capillary for visible damage like pinched, Crushed, over-extended armor on the capillary

Output not linear 1) Check for dented diaphragm

2) Check for frozen polymer on tip

Erroneous Pressure Reading 1) Check Data Units/Engineering units for correct setting

2) Was Transmitter zeroed at process operating temperature with no pressure applied

3) Check mounting hole for proper depth dimension. Transmitter tip may be recessed too far from polymer flow and pressure sensing may be deadened from polymer

buildup in from of tip

4) Check mounting hole for concentricity by using Gauge Plug in transducer cleaning tool kit (P/N 200100) to check for side loading of transducer tip. Dykem bluing should only be rubbed off at the 45° sealing surface and threads

5) Remove and check Transmitter tip for damage. Tip face should be free of dents or tears in the diaphragm material. It should be completely flat and free of frozen polymer

TROUBLESHOOTING

6) Always insure that mounting hole is clear of frozen polymer or any other obstruction before mounting the transmitter

7) Check Flexible Capillary for any visible damage like pinched, crushed, over-extended armor on the capillary

No Communications 1) Check wiring, particularly continuity and polarity of the

CAN-H and CAN-L connections to the Scanner. If these are reversed it will not communicate

2)Make sure 24 volts is present on V+ and V+ and that the power supply for the bus is of sufficient ampere rating for the amount of devices on the network

3) Using a DeviceNet configuration tool, check to see if all devices on the network are set to the same baud rate including the Scanner card

4) Using a DeviceNet configuration tool, check to see if there are any duplicate Node Addresses (MAC-ID) on the network, if so assign a new address to one of the conflicting devices

5) Ensure that the network is configured correctly and the Scanlist has downloaded correctly to the DeviceNet Scanner

6) Verify that the EDS file in use is correct and or the latest version (Available on the Dynisco website

www.dynisco.com)

7) Verify that the maximum line length for the baud rate selected is not exceeded (See chart below)
