The Eltav wireless sensor system revolutionizes industrial processing enabling real-time data sharing throughout a facility to increase industrial efficiency and productivity. Moreover, Eltavs WKVD IOM Page 4 Eltav Wireless Monitoring System wireless sensor technology offers reliable, autonomous process control to improve product quality, increase yield, and reduce costs. The Eltav Wireless Valve Monitoring System provides real-time information about the status of valves installed in process plants. The data is fed directly into the customers control system thereby reducing failure while increasing safety and yield. The Eltav System is based on the ZigBee Pro standard protocol and serves as an add-on layer, over traditional process management systems, providing enhanced monitoring capabilities, with considerably reduced complexity. The Eltav system includes support for a wide range of standard interfaces, physical and logical, that are common in the industry. This makes the Eltav system, from the perspective of connectivity, almost transparent for system designers and integrators, since they can easily integrate the Eltav system into any of the most widely-used system architectures in the process industry. The Eltav Wireless Valve Monitoring System has the following main functionalities:

Manual Valve Operation Monitoring: Many process valves are activated manually by field operators who receive instructions from the control room. Such manual processes are vulnerable to human error and can result in substantial damage and poor yield. The Eltav system provides the plant with an efficient, cost-effective solution to monitor installed devices. Actuated Valve Operation Monitoring: Although actuated process valves are activated remotely, many do not have any feedback on the operation and, in cases of actuation failure, a false perception of the valve position may be reported. The Eltav solution complements the actuated operation with a full monitoring feedback. Actuated Valve Maintenance: Wear and tear of actuated valves can result in a broken shaft (causing an excessively fast response), or in shaft deterioration that slows down the valve's movement. The dynamic profile of actuated valves during transactions must consistently remain within a pre-set range. Whenever these limits are breached, an alarm is generated. Partial Stroke Monitoring: Static valves that remain in the same position for long periods of time may lose their operational flexibility. To facilitate periodic instruction of such a valve to move, the Partial Stroke Test (PST) is initiated, either by the control system or manually. Valve positioning monitoring allows such a PST to be recorded and stored for audit and evidence. WKVD IOM Page 5 Eltav Wireless Monitoring System WestlocK Valve Device (WKVD) An Eltav Valve Device (WKVD) is bracket-mounted to any type of valve or actuator and using the standard wireless 802.15.4/ZigBee Pro, 2.4 GHz protocol wirelessly transmits and receives messages relevant to the position status of the valve in real time. The WKVD is powered by two half AA Lithium batteries. In nominal operation, the battery life of the WKVD is above 5 years. A battery pack can be replaced in the field. The WKVD includes a shaft that is fastened to the valves stem through a special cylinder. It transfers the angle position of the stem to the WKVD. An internal WKVD sensor measures the circular position of the WKVD shaft thus providing information about the angular position of the stem in degrees relative to the valve. The WKVD reports the valve position (angle) immediately when motion of the valve lever is sensed or every predefined period (configurable). The WKVD temperature, WKVD battery status, and other WKVD keep-alive information are broadcast with every WKVD message. Each WKVD message is transmitted with a real time stamp. In between transmissions the WKVD is in dormant status to save battery power. The WKVD also consists of a Low Frequency (LF) receiver for receiving setting commands from the Operator Device and to commission, decommission, calibrate, and setup the unit and to perform diagnostic procedures. WKVD IOM Page 6 Eltav Wireless Monitoring System Valve Device Router (R) Each WKVDR collects and routes data from nearby WKVDRs and up to 32 associated WKVDs, and transmits the information towards the control center by hops from WKVDR to WKVDR. The WKVDR acts as a relay that retransmits the messages received from a remote WKVDR, through the ZigBee wireless network, until they reach a TWKVDR (see below for details). Data transfer redundancy is assured by automatic routing of the wireless devices through a mesh topology and providing multiple TWKVDRs for each wireless network. Tunneling Valve Device Router (TVDR) The Tunneling Valve Device Router (TVDR) is the last-hop VDR that transfers collected data from VDRs to the Eltav Gateway. Several TVDRs can be connected, via TCP/IP, to the Eltav Gateway (thus ensuring full redundancy and avoiding a single point of failure). EMS Server The EMS Server is the central software server on the TCP/IP network. It maintains the wireless network, performs data logging, and publishes sensor information to clients and to the customers monitoring and control systems (PLC, SCADA, etc.) EMS Clients GUI Client: Provides a view of sensor data and network status and allows configuration of remote sensors and alarms. Connectivity Client: Forwards Valve Device data and status to the third party PLC, DCS and SCADA. Supported protocols are MODBUS RTU, MODBUS TCP/IP and OPC DA. PLC Adapter The PLC Adapter (PLCA) is a hardened connectivity device that supplies real-time data to PLCs/HMIs that reside on the plants dedicated network. The PLCA transfers relevant data from the Eltav Network and transfers it via MODBUS RTU and/or MODBUS TCP/IP in real time to PLCs/HMIs. The PLCA is seamlessly situated on the Eltav Network between the EMS and TVDRs and extracts the requested device information from the data stream. From this position in the Eltav Network the PLCA also acts as a redundant network manager keeping the Eltav Network alive in case of Gateway unavailability of any reasons. WKVD IOM Page 7 Eltav Wireless Monitoring System Operator Device The Operator Device (OD) is a hand-held device that enables the field operator to communicate with a selected field device (WKVD/VDR/TVDR) using low frequency and ZigBee. Such one-on-one communication provides the field operator a transportable and effective control panel to independently perform various operation and maintenance tasks. The OD delivers messages to operators, reports on performance, and is used to support installations, configuration, provisioning, and maintenance. Eltav Management System The Eltav Management System (EMS) processes collected data, monitors it, and delivers it to various typical clients at the process control management system. Such clients vary in various levels of the process control from the high level HMI and down to the line controllers (PLCs). The Eltav Management System supports such typical clients and data/indication and uses generic interface converters to provide the required interface accordingly.

Operation Installation Specifications Configuration Troubleshooting Maintenance 2.1 Valve Device Overview Figure 2: WKVD Module WKVD IOM Page 9 Eltav Wireless Monitoring System The Eltav Valve Device (WKVD) is the sensing component of the Eltav Wireless Monitoring System. It is installed on top of a valve or actuator and consists of a stem attached mechanically to the valve or actuator axle. The WKVD includes sensors that measure the angle which corresponds to the opening status of the valve (in degrees and opening percentage). The valve status is transmitted by an internal bi-directional transceiver that is based on the standard ZigBee Pro protocol. A dedicated Low Frequency (LF) receiver, in the WKVD, supports advanced maintenance, calibration, and provisioning procedures using the Operator Device

(OD). The WKVD provides real-time information about a valves status directly into the control system thereby reducing failure and risk while increasing safety and yield. 2.2 Valve Device LEDS and Indicators Table 1 and Error!

-40C<<Ta<<+80C Intrinsic safety Zone 1/21 2.4 Installation Case Material Operating Temperature Sealing FCC / IC ATEX The WKVD is a module which should be installed in a compatible box. The WKVD has an effective valve position (angle) measurement range of about 110. On the stem of the WKVD, an axle spline indicates the position of the stem (valve). On the bottom of each WKVD there are two etched marks indicting a range of 90. This is the effective motion zone of the WKVD's stem to measure the position of the quarter turn valves (Error! Reference source not found.). To avoid erroneous behavior, when installing the WKVD on a quarter turn valve or on an actuator verify that the axle spline is always positioned between the two etched lines (the motion zone). WKVD IOM Page 13 Eltav Wireless Monitoring System All WKVDs are factory calibrated such that the motion zone of the position measurement range is centered. Do not remove the lower PCB from its casing, or factory calibration might be damaged. 1. When installing the WKVD on a quarter turn valve or actuator, verify that the axle spline is always positioned in the range between the two etched marks indicating the motion zone. 2. Perform the calibration procedures as presented in Section 0 in order to ensure that the relative positions of the WKVD and the valve are correct. 3. After mounting the WKVD on a valve or an actuator, calibrate the WKVD to set the open and closed boundaries of the valve/actuator. Calibration is performed by the OD communicating with the WKVD (refer to Section 0). This process must be performed locally using the OD via LF. This ensures the accuracy of the configuration. If installation is performed on an active line, partial calibration can also be implemented. When either the OPEN or CLOSED angle is set, the WKVD will automatically suggest the corresponding other angle as 90 degrees away. To achieve partial calibration, reset previous calibration angles prior to setting the current angle (RESET CAL by OD). The WKVD can also report a custom valve angle which has been preset in the process line to facilitate a position report which is defined as CUSTOM. This third state provides the user with the ability to return to a predefined setting for a particular valve. For example, the user sets the valve to a capacity setting which will be reported upon by the WKVD to the OD and/or EMS when the WKVD is within the tolerance values of the Custom state. This angle is always measured from the 0 angle, regardless of valve angle notation (open or closed). The CUSTOM angle can be set either on the OD (CAL>Set Custom) or the EMS. WKVD must be powered on before calibration can take effect. 2.5 Powering Up and Shutting Down the WKVD The WKVD is delivered in a shutdown state. While in this state, the motion sensing capabilities and the wireless radio are shutdown, and the device is ready to receive the LF command to power up and join a wireless ZigBee network. 1. To power up and join the device to a wireless network, use the OD and send the JOIN (or JOIN ALL) command to the WKVD. When the WKVD powers-up, a distinct flashing sequence of the LEDs is visible. The operation normally takes a few seconds. During this sequence, the WKVD validates that the battery has sufficient power for the initial process. If this is not the case, the power-up sequence might take longer (during which the LEDs are still flashing), until the power levels are high and stable. WKVD IOM Page 14 Eltav Wireless Monitoring System If this sequence takes longer than 4 minutes, replace the battery. If power up does not complete, contact your local distributor. Once powered up, the WKVD will automatically join the network that the OD is joined to. If the network does not exist (or the OD is not joined to a network) the WKVD will look for any other ZigBee Pro network that conforms to the set of configuration (passed by the OD). If no such network exists, the WKVD will keep trying to join the same network at slower intervals until the network is found / formed or until the WKVD is shutdown. Starting from firmware version 2.26, the WKVD will indicate the sequence of joining to the network with blinking the ONLINE LED twice every 7 seconds. 2. To shut down the WKVD, use the OD and send the LEAVE (or LEAVE ALL) command. Once the WKVD receives the LEAVE command, it will flash its LEDs send an acknowledgement to the OD and shutdown. The shutdown sequence normally takes a few seconds. However, if the WKVD has messages to send, it will keep sending these messages until completed or until 60 seconds have passed. Then a second sequence of LED flashing will occur and the WKVD will leave the network and shutdown. When shutdown, movement of the WKVD stem is not sensed by the WKVD and the LEDs do not blink as a consequence to the movement. The EMS and PLCA are aware of these events and reflect the change in the WKVD state. When the WKVD powers up and joins the network, it also appears in the EMS tabular display (if not already present) and becomes ONLINE. When shutdown, the WKVD informs the EMS (and PLCA) of this event prior to shutting down, and the EMS presents the WKVD as offline and SHUTDOWN. 2.6 Configuration Introduction As part of the installation process, the Valve Devices are configured using either the EMS

(remotely) or the OD (locally). The following information is stored inside the WKVD:

Extended ID information Thresholds Setting operational parameters Calibration WKVD IOM Page 15 Eltav Wireless Monitoring System Extended ID information A Network Name (an alias of eight alphanumeric characters) is set via the OD. The WKVD and T/WKVDR remember this name and this prevents a device from accidentally joining another network in the vicinity. Each WKVD has a unique factory set ID (the MAC address) allowing the management system to uniquely identify it and manage its data stream. In addition to that, user friendly IDs more easily remembered and understood by technicians such as the valve Tag and serial number can be used. To manually select a specific device, for a one-on-one session with the OD, perform the following options:

1. On the back side of a WKVD locate the label with its unique 6-characters ZigBee MAC address. 2. On the OD, in the Default mode, key in the MAC address by using the Up/Down keys to select the character and the Tab key to select the character location. 3. When done, press Enter. The selected device will open a one-on-one communication session with the OD. This is also discussed in Section Error! Reference source not found.. Thresholds The WKVD continuously measures various status parameters such as the dynamic movement of the valve, ambient temperature and battery voltage. These measurable parameters are normally limited to a threshold or range. Exceeding a threshold generates an alarm in the WKVD which is delivered with the normal status message to the EMS (and from there to the HMI/PLC). These thresholds and/or ranges are configurable as part of the system configuration. This is discussed in Section Error!

Reference source not found.. Setting Operational Parameters Operational parameters define the behavior of the WKVD. For example:

How often the WKVD should send a keep-alive signal. How often the WKVD should poll for pending messages (from the EMS). How often the WKVD should cause the LEDs to blink. How fast the WKVD stem should be sampled. This is discussed in Section Error! Reference source not found.. Changing operational parameters can affect the battery life of the WKVD and/or the sensing capabilities of the motion sensor. WKVD IOM Page 16 Eltav Wireless Monitoring System Calibration After mounting the WKVD on a valve or an actuator, the WKVD should be calibrated to set the open and closed boundaries of the valve/actuator. This process must be performed locally using the OD via LF. This ensures the accuracy of the configuration. Calibration, from the OD point of view, is discussed in Section Error! Reference source not found.. In order to achieve a successful calibration of the WKVD on the installed valve/actuator, follow these simple steps:

1. Verify that the WKVD is powered and joined to the same network of the OD. 2. Open an LF session between the WKVD and the OD 3. Navigate to the CAL menu in the OD and key in the following commands. Make sure that each command is acknowledged before moving to the next one. o Remove previous calibration using RESET CAL. o Where applicable make sure the valve is completely open and set the open angle using SET OPEN. o Where applicable make sure the valve is completely closed and set the closed angle using SET CLOSE. o If required set the custom angle using SET CUSTOM. o Apply the new settings using APPLY. The order of calibration SET OPEN before SET CLOSED or vice versa is not important. Perform the above steps at your convenience. The WKVD can also be run from default values or partial calibration. This is pertinent when an installation is performed on a hot line. A complete calibration process can be completed at a later time (after the valve has changed its state). Partial calibration only one state (OPEN or CLOSED) has been calibrated. The WKVD will assume that the remaining state is 90 degrees away. Complete calibration both OPEN and CLOSED states have been calibrated using the OD. When completing a partial calibration, do not send RESET CAL, otherwise the previous calibrated angle will be erased. WKVD IOM Page 17 Eltav Wireless Monitoring System 2.7 Troubleshooting Device Does not Power Up 1. Verify that the device has an installed battery pack. 2. Using the OD, send a Join/Join All command to the WKVD(s) from a distance of 10 to 70 cm (refer to Section Error! Reference source not found.). Sending a signal when the OD is too close to the WKVD (a few centimeters distance) will saturate the WKVD receivers and the transaction will be aborted. 3. When a successful transaction occurs, the LEDS flash in sequence for a few seconds (refer to Section 2.2). Device Is not Presented in the EMS 1. Verify that the EMS is active. 2. Verify that at least one TWKVDR is online (refer to Section Error! Reference source not found.). 3. Verify that the TWKVDR is connected to a wireless network (refer to SectionError!

Reference source not found.). 4. Verify that the WKVD and TWKVDR are in the same network. 5. If the NET LED does not flash during valve movement or LED flashing intervals:

o Verify that the OD is in the same wireless network as the TWKVDR and then shut down the WKVD and join it again to the active wireless network (refer to Section Error!

Reference source not found.). o The WKVD has not completed handshake with the TWKVDR. Wait 2 minutes for the action to be completed or reset the TWKVDR (refer to Section Error! Reference source not found.). o The WKVD is not in the same Connectivity Group as the TWKVDR and therefore cannot perform a handshake with the TWKVDR. Using the OD, open a session and set the Connectivity Group of the WKVD to 0. Alternatively, using the OD, open a session, read the Connectivity Group on the WKVD, and set it to the same Connectivity Group as that of the TWKVDR (or the opposite). Starting from firmware version 2.26, the WKVD will clearly indicate the following states:

WKVD is not joined to the wireless network the ONLINE LED blinks twice every 7 seconds. WKVD IOM Page 18 Eltav Wireless Monitoring System WKVD performs handshake the OPEN LED blinks once followed by the CLOSE and ONLINE LEDs. The sequence repeats every 7 seconds. Device Presents Invalid Angle Readings If valve angle readings are erratic or non-continuous (from 0 to -10 and then 110 to 50 (refer to Section 2.4). If the valve has not been properly installed, the stem might be outside the valid range of the motion zone indications resulting in this inconsistent angle report. Device Performs Continuous Resets (LEDs Constantly Flashing in Sequence) 1. The WKVD battery pack usage may be momentarily overextended. Allow it to refresh for up to 4 minutes before continuing. 2. The fuse on the battery pack is blown. Verify and replace the battery pack. The WKVD LEDs continue to flash even if the fuse is blown. 3. The WKVD battery may be run down. In such a case, replace the battery. 4. The WKVD configuration may be corrupted. In such a case, replace the WKVD and return the faulty unit to your local representative. OD/WKVD Communication Is Temporarily Suspended If communications are suspended and acknowledgements are not received by the OD, or the WKVD does not react (LEDs flashing), reopen the session between the WKVD and the OD (refer to Section Error! Reference source not found.). Representation on the WKVD Is Unusually Slow This is usually caused by a temporary impediment to the wireless signal caused by an obstacle blocking the signal (e.g. a parked vehicle). If the obstacle cannot be identified or moved, add another WKVDR. The TX LED of the WKVD flashes more frequently than usual in such cases. WKVD Reacts but Does not Return an Acknowledgement to OD 1. Verify that the OD is in ONLINE as presented in Section Error! Reference source not found. and in the same network. WKVD IOM Page 19 Eltav Wireless Monitoring System 2. Verify that the ZigBee network is properly functioning as presented in Section Error!

Reference source not found.. Without ZigBee network support, the OD can use only one way communications on the Low Frequency (LF) channel (from OD to WKVD). Thus no acknowledgement from the valve device can be received. Only an OD operating in the same wireless network as the WKVD can receive acknowledgements from the designated WKVD. The WKVD Tag or Setting Is not Displayed on the EMS If a WKVD has migrated to the current network from a shutdown or out-of-reach network, the WKVD will only send its settings and will not update its Tag. In order to update the Tag of the WKVD in the EMS (or PLCA), perform the following steps:

1. If the EMS was restarted on a new computer or the EMS database was erased or corrupted, send a Group Report from the EMS to request all WKVDs and T/WKVDRs to report their configurations (refer to Section Error! Reference source not found.). 2. If the previous step was unsuccessful or not applicable, power down (LEAVE) the WKVD and power it up again (JOIN). WKVD Does not Answer to IDENT Signal from OD Refer to Section 0. Valve Dynamics are not Shown in the EMS 1. In the EMS Settings tab, verify that WKVD configuration is as follows:

o Valve Type is ACTUATED o Operation Mode is set to DYNAMICS. 2. If the reported configuration is different, change to the above, and click SEND on the EMS. 3. Verify that the valve has changed its configuration by moving it a few times and click REFRESH. 4. After performing the above, move the valve again and the dynamics should be displayed on the EMS Services tab. WKVD Returns to EMS after Deletion from Table 1. Deleting the WKVD from the table only clears it from the EMS database but does not turn the device off. 2. To turn off the WKVD, open a session between the WKVD and OD, then press LEAVE on the OD. WKVD IOM Page 20 Eltav Wireless Monitoring System Faulty WKVD Calibration Results If, during a Calibration session on the OD, steps are not performed in sequence, or a WKVD does not receive some of the commands, the resulting calibration may be faulty. 1. In general, if an Acknowledge is not received for a desired command and the + is not displayed, resend the same command again. 2. To perform partial calibration (only open or only closed), send a Reset Cal command prior to sending the Set Open or Set Close commands. Calibration will be applied only after sending the Apply command. In any step of the process, failure to receive the +

acknowledgement might indicate that the WKVD has not received the desired command, in which case the command should be resent. 3. If a partial calibration was performed and you wish to complete it, do not send Reset Cal, otherwise the previous stored angle settings will be erased. Refer to Section 0. There is no harm in sending the same command twice as long as the WKVD does not move. WKVD Information is not Presented in HMI/PLC Refer to the Chapter Error! Reference source not found. for a detailed explanation about system connectivity. Following are a few common instances in which WKVD information does not reach the HMI/PLC. 2.7.1.1 EMS Connectivity 1. If using EMS for connectivity (rather than PLCA), verify that connectivity is enabled

(File>Connect). 2. Perform a reconnection by choosing File > Disconnect and then File > Connect. 3. On the WKVD Services tab, press Refresh Connectivity (refer to section Error! Reference source not found.). 2.7.1.2 In All Connectivity Cases 1. Verify that Valve Tag in the System tab in the EMS is correct (case sensitive). 2. Verify that the HMI/PLC is physically connected and/or properly configured, by checking the WATCHDOG signal. The WATCHDOG signal is a signal from the application side of the EMS/PLCA to the HMI/PLC. When this signal stops changing, the communication state is offline (refer to Section Error!
