Do not remove the protective cap on the Vertex brand sensor snout tip until ready to install. If the cap is not in place, do not allow the tip to strike any object – the diaphragm may be dented inadvertently. Aluminum thread caps can be ordered from Dynisco for best protection of the diaphragm tip on spare sensors. (Part numbers can be found i n section 12). Check the port before mounting the sensor Before mounting the Vertex brand sensor, check the process connection carefully. The Vertex brand Sensor must only be mounted in process connections that satisfy the requirements below. A process connection that does not s atisfy these requirements can damage the sensor. Damage to the sensor is commonly caused by installing into an improperly machined hole. By forcing a snout into an undersized or eccentric hole, the sensor diaphragm may be damaged and as a result the sensor may not function as specified. Insure the process connection is clear of any debris and is machined to the proper dimensions. Dynisco offers a cleaning tool kit designed for use in removing excess plastic from standard mounting holes for pressure a nd temperature sensors. (See manual section 12). The abrasion from threading a sensor into a mounting hole with an incorrect thread size may damage the s ensor threads. This damage may prevent a proper seal, resulting in material leakage, and the instrument may not function as specified. The proper dimensions for the mounting hole must be used to avoid thread galling (welding via diffusion at point contacts over time at temperature and pressure). The threads are, an industry standard of ½ ‐ 20 UNF 2B. A mounting well gage plug should be used to verify that the mounting hole is correctly machined and cleaned. It is good practice to check the mounting hole before installing the sensor. One procedure is to coat a gauge p lug (Included in the cleaning kit, or available separately ‐ see section 12 for part numbers) with Dykem machine blue ...

After verifying the port, prepare the tip In applications such as plastics extrusion involving high temperature operation and/or repeated thermal cycling a good high quality anti‐seize compound should be applied to the threaded surfaces of the sensor and 45° seat before mounting. (High temperature anti‐seize compound prevents seizing, galling, and cold welding of the sensor.) Make sure that anti‐seize does not contaminate the wetted surfaces if it is not compatible with the process. Install the Sensor After applying the anti‐seize, install the sensor into the mounting hole. Allow time for the sensor snout temperature to equalize to the process temperature before tightening the sensor. This will help eliminate thread galling and ease removal later. There should be NO pressure applied at this time. After temperatures have equalized tighten the sensor into the mounting hole. Always use a torque wrench applied to the designated wrench flats while screwing the sensor in and out. Do not exceed the torque specification, in section 4.4 or apply the tool to the housing or housing/sensor connection. During installation, take care not to damage the electrical connector. This is probably the most vulnerable part of the Sensor, other than the sensing diaphragm itself. Denting the connector shell or bending a pin could put the sensor out of commission. When installing a sensor with a flex, use the mounting bracket provided to secure the electronics housing. Take care to align the housing so the zero and span adjustment access holes can be reached with a screwdriver. Make sure that the electronics is not secured while installing or removing the sensor from the mounting port though. The electronics must be free to rotate as the snout rotates. Avoid kinking or crushing the flexible stem. Do not violate the minimum flex bend radius as specified in section 4.4. P/N: 974155 Rev: 091316 | ECO: 46774 www.dynisco.com -26-...

From lab to production, providing a window into the process Attempt to minimize exposure to high temperatures The Vertex brand sensor can be used in media temperatures up to +400⁰C (based on configuration). As stated in the temperature specifications section (section 4.5) of this manual, the maximum allowed operating temperature for the electronics housing is +85⁰C and the maximum allowed operating temperature of the transition housing is +150⁰C. Approximations of the operating temperatures of the housings can be obtained by measuring the bottom surfaces of the housings closest to the process connection. Exceeding these maximum operating temperature values can result in PT malfunction and damage. Do not install the PT in places where these temperatures are exceeded. The operating temperature of the transition housing can be strongly influenced by the exposed process c onnection length. Exposed process connection length is defined as the length from the end of the transition electronics enclosure (closest to the process connection) to the point where the snout enters the process equipment or i nsulation covering the process equipment. For rigid configuration PTs (no flex) the operating temperature of the electronics housing can also be strongly influenced by the exposed process connection length, because the electronics housing is directly connected to t he transition housing in this configuration. For PTs with a flex, the electronics and transition housings are separated by the flex and therefore the operating temperature of the electronics housing is more strongly influenced by t he ambient temperature. The installation orientation of the rigid snout with respect to the barrel also has an influence on transition housing operating temperature. The temperature rise in the electronics and transition housings due to electrical self heating is minimal (depending on configuration, approx 5‐6⁰C max in the electronics housing and approx 2‐3⁰C ...
If a transducer is positioned too far back in the mounting hole, a stagnant pool of melted plastic will build up between the transducer tip and the screw flights. Over time this plastic will degrade to carbon, which will prevent t he transmission of an accurate pressure signal. On the other hand, if the transducer extends too far into the barrel the screw flights can shear off the unit’s sensor tip. After removing the sensor, the port can be plugged with a hole plug, if necessary. See the accessories in section 12. Always remove the sensor prior to cleaning the machine with abrasives or steel wire brushes. Also, do not clean the sensor with hard objects, such as a screwdriver, a wire brush, etc. This could possibly damage the s ensor. Protect the tip after removal After removing the sensor, immediately protect the tip by installing the protective cap. Aluminum thread caps can be ordered from Dynisco for best protection of the diaphragm tip. (See section 1 2) P/N: 974155 Rev: 091316 | ECO: 46774 www.dynisco.com -28-...

UTILIZING THE ZERO AND SPAN ACTUATORS When the sensor output needs to be corrected due to mounting location and temperature shift, the zero actuator can be used. Please wait until the process has been brought to operating temperature before zeroing. The zero procedure is only recommended after the process temperature has stabilized, the snout has been tightened to t he specified torque, and the sensor electronics housing has been permanently installed. Normally a Rezero is all that is required after installation since the sensor span has been calibrated at the factory. In the event the full scale output is not correct when checked against a calibrated pressure source or dead weight tester, the sensor span can be adjusted via the Span actuator. Span adjustments can only be performed when applying a known calibrated full scale pressure to the sensor. The span actuator should never be used without zeroing the sensor with the zero actuator f irst. Do not adjust the Span potentiometer while Rcal is engaged! ZERO AND SPAN PROCEDURE Connect Power Supply and readout electronics to Vertex sensor. If commissioning on the bench with a dead weight tester or calibrated pressure source, ensure pressure connection is free of leaks. Apply power to the Vertex sensor and observe output with zero pressure applied. The output should indicate zero pressure. If not, proceed to step 4. Perform Zero Function mV/V units can only be zeroed when this feature is available on your indicator/controller. No local zero capability. Voltage units can be zeroed using on board zero potentiometer. Remove seal screw and adjust potentiometer until desired output is achieved. Replace seal screw when complete.

mA units have a variety of on board Zero Adjustments types (based on configuration), i.e. potentiometer, pushbuttons, and HALL Effect Switches. o For units with potentiometers, remove seal screw and adjust potentiometer until d esired output is achieved. Replace seal screw when complete. o For units with pushbuttons, remove seal screw, using a 2mm or smaller Allen Key, depress pushbutton for ½ sec, release pushbutton for ½ sec, depress pushbutton for ½ sec and release. Replace seal screw when complete. o For units with HALL Effect Switches, unthread zero screw from endplate, depress screw, release screw, depress screw, release screw and return screw in endplate (failure to return the screw on units with HALL Effects Switches will cause the unit to go into failsafe). 5. Steps past this point are not part of a normal bench setup and should only be performed by qualified individuals. The Vertex sensor has been factory calibrated with highly accurate pressure generators. Span adjustment should only be performed on a calibrated pressure generator at 100%FS. 6. Apply Full Scale pressure and verify output. If output indication is incorrect, adjust the span potentiometer. AVOID COLD STARTS! In plastics, both the sensor and extruder can be damaged if the extruder is not brought up to operating temperature before the machinery begins operating. A sufficient “soak time” must be provided for the plastic to go from its solid to molten state before the extruder drive is started. THE OPTIONAL TEMPERATURE OUTPUT The sensor can also detect the temperature of the tip. J and K thermocouple outputs are available as an option. The thermocouple is an integral part of the sensor/flex assembly and must be ...

The purpose of Rcal is to make it possible to match the sensor to the Pressure Indicator/Controller with a “two point calibration.” (Two points define a line.) Setting up the instrument in this fashion is much more a ccurate through a single point offset adjustment. When the sensor is fully installed and the machine is at operating temperature and at zero pressure, the indicator may be “zeroed” using whatever mechanism nulls it. Afterward, the Rcal pins on the sensor may be shorted to simulate a pressure of 80% full scale to complete the calibration and allow the indicator span to be adjusted. Caution ‐ Do not adjust Span with Rcal activated. The Rcal signal of Vertex is a fixed voltage added to the Zero Output. It is not influenced by Span potentiometer adjustments!

DEFINITION OF “RESTORE FACTORY DEFAULTS” ................ 4 5 HART COMMUNICATOR FAST KEY SEQUENCES ................ 4 5 The zero procedure is only recommended after the process temperature has stabilized and the electronics housing has been permanently installed. When the zero trim function is selected (HART Quick key 1,2,5,1,3,1) the output will be corrected to reflect zero pressure. This is done by the transmitter electronics automatically by adjusting digital PV to zero and analog output will be 4 mA. Normally a Zero Trim is all that is required after installation since the Transmitter span has been calibrated at the factory. In the event the Full Scale output is not correct when checked against a calibrated pressure source or dead weight tester, the Transmitter span can be adjusted by performing the Sensor Trim function. This is p erformed by first applying Zero Pressure and selecting Lower Sensor Trim (HART Quick Key 1, 2, 5, 1, 3, 2) and following the prompts on the HART Communicator. When complete, apply a known calibrated full scale pressure to the Transmitter and selecting Upper Sensor Trim (HART Quick Key 1, 2, 5, 1, 3, 3) and follow the prompts on the HART Communicator. When complete, the transmitter electronics will have adjusted the digital PV to correct to full scale output. ATTENTION Never perform upper sensor trim without performing lower sensor trim first.

HART Communicator to function properly. ATTENTION A minimum of 250 Ohms resistance must be present in the loop. The HART Communicator does not measure loop current directly. The HART Communicator can interface with the device anywhere along the 4‐20 mA cable as shown in the following figure. 6.3.3 PROCEDURE 1. Connect Power Supply and HART Communicator per the above diagram. 2. If commissioning on the bench with a dead weight tester or calibrated pressure source, insure pressure connection is free of leaks. 3.

9. Next, using calibrated pressure source, apply pressure equal to value set in URV in step 6. Output should equal 20 mA. If output does not equal 20 mA proceed to step 10. 10. To calibrate full scale output, first apply pressure equal to full scale pressure of unit. Next perform Upper Sensor Trim (Fast Key 1,2,5,1,3,2). Output should now equal full scale pressure. 11. If Transmitter Output Damping is required, set PV Damping (Fast Key 1,3,5) to the appropriate value. 12. Press the left arrow key until the HART Communicator is off‐line then turn the power o ff. The pressure transmitter is now ready to be installed in the process. P/N: 974155 Rev: 091316 | ECO: 46774 www.dynisco.com -37-...

Using the HART communicator, the specific condition that triggered the fail‐safe mode alarm can be read for diagnostic purposes. (See Status in the HART menu tree.) In a fail‐safe condition the PV is not affected and can still be read using the handheld HART communicator. For process related fail‐safe conditions, the transmitter will remain in the alarm state until the source of error disappears. If certain electronics errors are detected, the fail‐safe condition will latch until a reset is performed by either cycling the power or through a software command. NAMUR Compliant Saturation and Alarm Values 4 ‐ 20 mA Saturation 4 ‐ 20 mA Alarm Low 3.8 mA 3.6 mA High 20.5 mA >21 mA You can alter the actual transmitter mA output values by performing an analog output trim using the HART Communicator.

Reranging The device allows for the 4 mA and 20 mA points (LRV and URV respectively) to be adjusted so that output resolution can be improved. A Re‐range or “Turndown” ratio of 6:1 is possible. Accuracy specifications remain dependent upon the Full Sensor Range without any turndown applied. Three methods of Re‐ ranging the transmitter are o utlined below. Note: If pressure applied to the transmitter is not in the range of the 6:1 turndown ratio, the transmitter will reject the Span attempt. This will be indicated by the output not adjusting to 20 mA after a few attempts using the Span Actuator. Reranging TV (MPT option only) On a device with the MPT option, there is a second 4‐20mA output that is proportional to the snout temperature. By default the TV LRV and TV URV are set to 0 and 400C respectively. The secondary 4‐20mA output can be reranged by changing TV LRV and TV URV. Reranging via Zero/Span Actuators When HART Communication is not used, LRV and URV values are entered by applying zero pressure to the device and “Rezeroing” by: For units with Pushbuttons Do not remove seal screw when the circuit is live in a hazardous area. Remove zero pushbutton seal screw. iii. Using a 2mm or smaller Allen key, depress the pushbutton for a ½ second. Release pushbutton for a ½ second. Depress the pushbutton again for a ½ second and release. P/N: 974155 Rev: 091316 | ECO: 46774 www.dynisco.com -40-...

URV or Full Scale Turndown is performed by applying any pressure, within the 6:1 ratio of the transmitter that you want to be the 20 mA point. When the pressure is held steady: For units with Pushbuttons Do not remove seal screw when the circuit is live in a hazardous area. Remove span pushbutton seal screw. iii.

This is the temperature at which the transmitter will output 20 mA on the secondary mA output as entered directly by the user. Rerange LRV By Applying Pressure (1,2,5,1,1,1,1) This is done by applying a known pressure and initiating the procedure so that the transmitter adopts the pressure as the 4 mA point. Note: This should only be performed with a Calibrated Pressure Source. Rerange URV By Applying Pressure (1,2,5,1,1,1,2) This is done by applying a known pressure and initiating the procedure so that the transmitter adopts the pressure as the 20 mA point. Note: This should only be performed with a Calibrated Pressure Source. Recall Factory Trim (1,2,5,3) This is used to restore the Zero, Lower, and Upper Trim to the Values as set from the Factory. R‐Cal Set % (1,2,5,1,4,1) This is used on versions with a Rcal. By activating R‐Cal, the output will be set to the percentage of span set by this function. Default is 80%. Setting Rcal to 0%, disables the Rcal function. Damping (1,3,5) The damping time constant affects the speed with which the primary output signal reacts to changes in pressure as shown in the figure on the following page. Damping is off by default but values between 0 and 30 seconds can be set using the handheld communicator. The damping value must be entered in integers. If non‐integers are entered, the system rounds to the next integer. P/N: 974155 Rev: 091316 | ECO: 46774 www.dynisco.com -42-...

Reads Device Status from device. PV Unit (1,3,2) The pressure unit defines the unit of measure that the pressure‐specific parameters are transmitted in. The device can be configured in the engineering units of psi, Bar, MPa, and kgf/cm² or as a percentage of Full Scale (FS). After selecting a new pressure unit, all entries for pressure are recalculated to the new unit, using the following c onversion rules: 1 psi = 0.068947 Bar = 0.0068947 MPa = 0.070309 kgf/cm² Tag (1,3,1) An inventory “Tag” identification number may be stored in transmitter memory (8 characters maximum). Software tag is a single question mark by default. Descriptor (1,3,4,2) A 16 character text can be entered for further description of transmitter e.g. location, function, position, etc. Message (1,3,4,3) A 20 character message can be set and displayed on the HART Communicator. SV Electronics Temperature (1,1,7) Temperature measured on the Electronics Assembly is used for reference and factory diagnostics only. TV Snout Temperature (1,1,4) Temperature measured at the snout tip (MPT option only). P/N: 974155 Rev: 091316 | ECO: 46774 www.dynisco.com -43-...
RESETTING TO FACTORY DEFAULT SETTINGS The factory settings for the sensor (including zero and span) can be restored if they are changed inadvertently using the Zero/Span Actuators or the HART communicator. The list of parameters restored is shown b elow. Make sure Control System is in Manual mode. Temporary loss of Loop Output during Electronics Re‐boot may occur. To reset the sensor using the actuators, use the following procedure: For units with Pushbuttons Do not remove seal screw when the circuit is live in a hazardous area. Remove zero and span pushbutton seal screws. iii. Using a 2mm or smaller Allen key, depress the pushbuttons for a ½ second. Release pushbuttons for a ½ second. Depress the pushbuttons again for a ½ second and release. For units with HALL Switches Unthread Zero and Span screws from endplate Depress screws iii. Release screws Depress screws Release screws Restore screws in endplate Note: The screws must be threaded into the endplate for normal operation. Failing to do so will cause the device to go into failsafe. At this point, the LRV and URV will be set to factory defaults. P/N: 974155 Rev: 091316 | ECO: 46774 www.dynisco.com -44-...
