5 SECTION 1: INTRODUCTION 1.1 Description With the increase in demand for effective, interactive and non-intrusive systems, Net Safety has released its HART for Flame product providing HART communication with distinct flame detectors. This involves HART Communication with the Phoenix Triple IR, UV/IR and UV Flame Detectors along with the Hydrogen Flame Detection line of UV and UV/IR Flame Detectors. The introduction of HART Communication with flame detectors allows convenient access to the Flame Detector s features and provides easy on the spot monitoring. This is important for effective and reliable maintenance. Access to the HART menu structure and functions of the flame detector is gained by using the HART Communicator. This may also be done using and any other HART communication devices that are compatible with the enhanced device description language (EDDL) of Net Safety s Flame Detectors. Product components: This HART for Flame product has two component products; a flame detector with Analog /Analog- Digital output alongside a HART Communication Output interface. This HART Output circuitry is enclosed in Net Safety s Explosion Proof Multipurpose Junction Box and allows users to choose Analog- Hart or Analog-Hart with Relays outputs. The HART for Flame product is available in Aluminum and Stainless Steel. Choice of flame detector: The model flame detector used with the HART Output interface will depend on users choice and nature of the application. In specific cases users may want to detect hydrogen based fires in which case the UV/IRS-H2-A/AR or the UVS-H2-A/AR flame detector based HART for Flame product would be suitable. In other cases users may want to use either the IR3S-A/AD, UV/IRS-A/AR or the UVS-A/AR flame detector based HART for Flame product to detect Hydrocarbon based fires. Refer to available models offered below. Available Model HART for Flame Product (this includes HART Flame Junction Box interface): UV/IRS-AH/AHR, UVS-AH/AHR, UV/IRS-H2-AH/AHR, UVS-H2-AH/AHR ATEX models: UV/IRS-AH-X/AHR-X, UVS-AH-X/AHR-X, UV/IRS-H2-AH-X/AHR, UVS-H2-AH- X/AHR-X Both CSA/FM and ATEX models are available in Aluminum and Stainless Steel. Available Model HART Flame Junction Box interface: JB-MPHF-A (HART output, Aluminum version), JB-MPHF-S (HART output, Stainless Steel version), JB-MPHFR-A (HART & Relay output, Aluminum version), JB-MPHFR (HART & Relay output, Stainless Steel version). System configuration: After choosing the type of flame detector based on the HART for Flame product, the system should be configured. This is done via DIP Switch 2 (SW2) located on the HART Flame Junction Box PCB. See Table 1 when configuring the system. MAN-0119 Rev 1 HART for Flame Page 4 of 28

6 1.2 Unpack Carefully remove all components from the packaging. Check components against the enclosed packing list and inspect all components for obvious damage such as broken or loose parts. If you find any components missing or damaged, notify the representative or Net Safety Monitoring immediately. 1.3 Mounting The HART Flame Junction Box has three ¾ inch-14 NPT conduit entries. The flame detector will be connected to one of these entries. Connection of conduit and cable glands to remaining conduit entries should be done so by use of appropriate tools. A 6mm Hex Key is required for installing or removing conduit entry plugs. The junction box has mounting holes for installing directly on a wall or to a pole as desired. The junction box is supplied with one ATEX stopping plug. 1.4 Installation Considerations Point flame detector toward where the flame is expected. Ensure an unobstructed view of the area to be monitored. Employ more than one flame detector and HART Flame Junction Box to ensure the hazard is fully covered. Mount the flame detector and HART Flame Junction Box a few feet (about 1 metre) below the ceiling so the flame detector can respond before being blocked by smoke accumulation at the ceiling. If dense smoke is likely to accumulate prior to flame (as in an electrical fire), supplement flame detector(s) with other protection such as Net Safety Monitoring Airborne Particle Monitor. The flame detector should be accessible for cleaning the window and reflector surfaces. Tilt the flame detector downward a minimum of 10 to 20 to reduce dirt and dust accumulation which could obscure the detector s viewing window. Securely mount the flame detector and HART Flame Junction Box so as to reduce vibration as much as possible. When located outside, the flame detector s sensitivity can be reduced by heavy fog, rain and/or ice. Consider shortening the time delay settings when smoke is expected to accumulate before or during a fire. See relevant manual. Reduce sensitivity setting if false alarms, related to surrounding activities, occur. When installed near or on water (such as an off shore platform), be sure to take into account the low horizon level when tilting detector downward. For more on installation considerations on flame detectors refer to specific flame detector manual. 1.5 Wiring Warning Wiring must comply with all applicable regulations relating to the installation of electrical equipment in a hazardous area and is the responsibility of the installer. Proper shielding and grounding procedures, for the specific area must be followed. Consult local electrical code and /or qualified personnel before wiring. Warning Do not open the HART Flame Junction Box or flame detector in a classified area (Do not open when an explosive atmosphere may be present). The area should be de-classified prior to opening. MAN-0119 Rev 1 HART for Flame Page 5 of 28

7 1.6 Sealing Warning To fully avoid any environmental exposure (water ingress), the use of seals is recommended, especially for installations that use high-pressure or steam cleaning devices in proximity to the HART Flame Junction Box and flame detector. It is recommended that explosion-proof drains and conduit breathers be used. Changes in temperature and barometric pressure can cause 'breathing' which allows moist air to enter conduit. Joints are seldom enough to prevent 'breathing'. Consult qualified personnel on sealing requirements relating to equipment, application and local regulations. 1.7 HART for Flame Dimensional Drawing The drawing below shows the dimensions of the Aluminum (AL) and Stainless Steel (SS) models of the flame detector with HART Flame Junction Box enclosure. Figure 1: Dimensional Drawing (Measurements are in Inches and Millimeters) Note: CSA/FM model shown ATEX model has an ATEX locking collar * M20 & ½ NPT threads also available SECTION 2: Operation The model flame detector will determine the model HART for flame unit being used. Specific combinations of SW2 positions (DIP Switch 2 positions) have been assigned for each available type of flame detector. Selecting DIP Switch 2 positions correctly will determine the operation of the unit. See Table 1 and Figure 2 or Figure 3. Once the system has been powered up, confirm operation by referencing the specific Flame Detector manual. Meter Test Jacks are available on the HART Flame Junction box PCB to check and monitor the current output (4-20mA). If the HART / Relay model junction box is being used, note that the relays are dry contacts and are Form C SPDT rated 5 Amperes at 30 VDC/250AC. MAN-0119 Rev 1 HART for Flame Page 6 of 28

8 If the HART Communicator is to be placed in the current loop, ensure that the HART Jumper (J5) is in the factory default position (pins jumpered), then place a 250 Ohm resistor in the current loop and connect the communicator across the resistor. Refer to Figure 2 or Figure 3 along with Current Loop power block diagrams and / or Typical Field wiring diagrams. If the HART Communicator is to be used with the HART Port connector for direct or remote communication, see Section Current Loop power configurations The two current loop power configurations available are the Non Isolated power configuration and the Isolated power configuration. When using the Non-Isolated power configuration (Non-Isolated current loop), the Non ISO / ISO select jumper (JP1) located on the HART Flame Junction box PCB should remain in its default position. ISO on the power terminal side is not used in this configuration. For the Isolated power configuration (Isolated current loop), JP1 should be placed over pin 1 and pin 2 and a separate power supply used to supply +24VDC to ISO on the power terminal side. See figure 2 or figure 3 for JP1 s location. Also refer to Current Loop power block diagrams and / or Typical Field wiring diagrams. Note: By factory default JP1 (Non ISO / ISO select jumper) is connected across pin 2 and pin 3 (Non- Isolated power configuration). Also by factory default the HART Jumper (J5) is connected (pins are jumpered). MAN-0119 Rev 1 HART for Flame Page 7 of 28

9 SECTION 3: Configuring the system When using the specific model flame detectors (IR3S-AD, UV/IRS-A, UV/IRS-H2-A, UVS-A, UVS-H2- A, IR3S-A), corresponding SW2 (detector configuration DIP Switch located on HART Flame Jbox PCB) positions have to be set. The correct combinations of position 1 and position 2 have to be made in order to have proper operation of the flame detector and HART or HART/Relay model Junction Box. See Table 1 and Figure 2 or Figure 3.

11 SECTION 4: HART Connection and Communication 4.1 HART Communicator connection The HART Communicator may be connected to the HART Flame Junction Box via the HART Port connector. Refer to Figure 4. For remote HART communication, the HART Communicator is connected to the Junction box interface via a HART Port connector and separation board (JB-MPH-A/S). See Figure 5. Refer to the HART Port connector manual (MAN-0083) and the Net Safety Multi-purpose Junction Box manual (MAN-0081) during installation. The HART Communicator may also be placed in the current loop wiring. Refer to Section 4. Place a 250 Ohm load resistor in the 4-20 ma current loop and connect the HART Communicator probes across the resistor. Do not install a resistor within the HART interface junction box. The total current loop resistance should be a maximum of 600 Ohms in order to have proper communication with the HART Communicator. Figure 4: Direct HART Communication This drawing is a general representation in connecting the system. Junction Box with HART interface Flame Detector HART Port connector (HPT-001) The HART Port connector ground wire should be connected to intrinsically safe ground. HART Communicator Probes/wires HART Communicator Warning Built within the HART Port connector are intrinsically safe barrier circuits, which are a grounded type barrier. The port requires this safe ground to divert the excess energy. The grounding of the HART Port must meet local safety guidelines. MAN-0119 Rev 1 HART for Flame Page 10 of 28

Important note and Instructions Note: Refer to The Net Safety Multipurpose Junction Box manual (MAN-0081) and HART Port connector manual (MAN-0083) when wiring for remote communication. Instructions: For remote HART communication, connect the HART Jumper (J5) located on the HART Flame Junction Box terminal board, across the pins (jumper pins). See Figure 2 or Figure 3 for location of the Jumper. MAN-0119 Rev 1 HART for Flame Page 11 of 28

13 4.2 HART Communication Protocol The HART protocol incorporates an Enhanced Device Description Language, (EDDL) that enables HART instrument manufacturers to define and document their product in a consistent format. This format is readable by handheld communicators, PC s and other process interface devices that support EDDL. For the Flame Detector- Junction Box Hart interface, handheld HART communicators, PC s and other process interface devices must support the latest 16 bits manufacture ID and 16 bits device type. For the 375 model HART Communicator the software version must be at least version 2.0. Establishing HART Communication with the flame detector and HART Flame Junction Box. 1. Ensure system is wired properly, then power up the unit and ensure no faults are indicated. 2. If the HART Port connector connected to the junction box as an interface, unscrew the HART Port connector s protective cap. 3. Connect the HART Communicator non-polarized probes to the 2 non polarized HART Port connector terminals. 4. If the HART Port connector is not used, ensuring the HART current loop jumper inside the junction box is in place. Then put the HART communicator probes across a resistor (min. 250 Ohms) within the 4-20 ma loop wiring. The maximum loop resistance of the wiring should be 600 Ohms. 5. Turn on the HART Communicator and proceed to initiate communication. If not familiar with the communicator, consult the specific HART Communicator manual for operating instructions. Important Notes: Proper analog signal output termination and minimum loop resistance must be completed in all cases to enable HART communication. Failure to provide proper analog signal output loop resistance will preclude all HART communication. If the HART Communication is not programmed with specific DD or does not support 16 bits IDs, the JB-MPFH can still connect to the communicator but in the Generic HART communication mode. In this mode, HART communication with the system will be established, but the Communicator will not recognize the system (unit). Generic HART communication will not provide access to the JB-MPHF EDDL menu and important set-up, diagnostics or operation functions. If you cannot find Net-Safety or JB-MPHF under Net-Safety on your Communicator, the specific EDDL is not programmed into communicator. Your HART Communicator will require an EDDL upgrade in order to access all the JB-MPHF functions. The HART Communication Foundation, ( manages the HCF Approved EDDL Library and programming sites for HCF Approved field communicators. A complete listing of the DD Library is available for download and provides manufacturer and device type file identification. See HART Menu Tree (Structure) on next page.

22 Appendix A: Electrostatic Sensitive Device (ESD) Definition: Electrostatic discharge (ESD) is the transfer, between bodies, of an electrostatic charge caused by direct contact or induced by an electrostatic field. The most common cause of ESD is physical contact. Touching an object can cause a discharge of electrostatic energy ESD! If the charge is sufficient and occurs near electronic components, it can damage or destroy those components. In some cases, damage is instantaneous and an immediate malfunction occurs. However, symptoms are not always immediate performance may be marginal or seemingly normal for an indefinite period of time, followed by a sudden failure. To eliminate potential ESD damage, review the following guidelines: Handle boards by metal shields taking care not to touch electronic components. Wear grounded wrist or foot straps, ESD shoes or heel grounders to dissipate unwanted static energy. Prior to handling boards, dispel any charge in your body or equipment. Ensure all components are transported and stored in static safe packaging When returning boards, carefully package in the original carton and static protective wrapping Ensure ALL personnel are educated and trained in ESD Control Procedures In general, exercise accepted and proven precautions normally observed when handling electrostatic sensitive devices. A warning label is placed on the packaging, identifying product using electrostatic sensitive semiconductor devices. MAN-0119 Rev 1 HART for Flame Page 21 of 28
