WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 4 06/16/2011 Safety Information Hazardous Environments The WESROC® RMS Cellular Tank Monitor (CTM) is designed for safe use in environments containing hazardous vapors. However, certain precautions need to be taken to ensure the safety of the person(s) working with the CTM, the tank, and any associated equipment. TO ENSURE SAFE OPERATION: Install the CTM according to the instructions contained in this WESROC RMS Cellular Tank Monitor Operation Manual. WARNING!!! Do NOT loosen or remove float gauge from a pressurized tank! Tank decompression can cause serious injury or property damage! WARNING!!! Do NOT connect the CTM to any apparatus or wiring from another manufacturer! Substitution of components may impair the intrinsic safety of the CTM! Clean only with a damp cloth to prevent the possibility of electrostatic discharge! Enclosure mounting bracket may contain aluminum – take care to avoid ignition hazards due to impact or friction! Battery Replacement The CTM uses a replaceable, intrinsically safe battery pack. Only replace with a model MT-9100BPK-02 battery pack from Independent Technologies, Inc. Use of any other power source will compromise the intrinsic safety of the CTM and will void the CTM warranty. Dispose of used battery pack properly. Radio Frequency Exposure To ensure that exposure to hazardous radio frequency radiation is prevented, the CTM must NOT be installed in a location where humans will be routinely within 20 centimeters of the CTM. To ensure that FCC requirements are met regarding radio frequency exposure, the CTM is NOT to be placed in operation where it will be co-located with another CTM. Co-location is considered to be where one operating CTM is within 20 centimeters of another operating CTM. Radio Frequency Interference This equipment (FCC ID number RWB-MT9100CTM and IC number 115A-MT9100CTM) has been tested and found to comply with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. Changes or modifications to this device not expressly approved by Independent Technologies, Inc. could void the user’s authority to operate this device.

WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 5 06/16/2011 Overview Device Characteristics The WESROC® RMS Cellular Tank Monitor (CTM) is used to remotely monitor the level of the contents of a tank. The tank level and additional event and status information are reported to the WESROC® RMS Host System (Host) at scheduled intervals. In addition, the CTM will report to the Host immediately to track tank events in real time. The CTM uses the GSM cellular network and the internet to transport this information. Communication with the Host is bi-directional which allows for remote configuration of the CTM should the tank monitoring requirements change or in the event that the CTM is moved to another site. The CTM also provides a local tank level display capability. The CTM can be configured to send short range radio data packets to a nearby WESROC® RMS Base Unit (Base Unit). Once initialized to the CTM, the Base Unit will provide the customer with a local display of tank level for up to eight tanks (depending on which Base Unit is used). Installation A basic CTM installation is easily performed in a few minutes by persons with a basic understanding of the tank equipment to be monitored and of the CTM device itself. Since the CTM is self-contained, the complete installation can be performed at the tank. No access to the customer’s residence or place of business is required. By default, the CTM is configured to monitor the most common type of tank, but may be re-configured to monitor a wide variety of tank configurations. The CTM may be remotely configured by the Host or may be configured on site by using the handheld WESROC® RMS Portable Diagnostic Unit. Power The CTM is battery powered, and due to its low power design will provide many years of remote monitoring before battery pack replacement is required. Battery pack replacement may be performed at the tank as the CTM and battery pack are both designed and certified to be intrinsically safe for use in hazardous environments.

WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 6 06/16/2011 Installation Mounting Location The WESROC® RMS Cellular Tank Monitor (CTM) is designed to be installed directly on the tank to be monitored. The CTM is connected to the tank gauge by the tank level sensor and sensor cable. The CTM itself may be attached to the tank by the supplied mounting magnets or by a mounting bracket. The CTM may also be located away from the tank if necessary to improve cellular reception. Versions of the CTM are available with a longer sensor cable to facilitate mounting the CTM further away from the tank. Tank Gauge The standard CTM is equipped with a hall-effect based tank level sensor. This sensor is designed to be snapped into a remote ready tank gauge dial. The sensor and dial are part of the R3D dial and sensor system manufactured by Rochester Gauges. R3D dials are available for a wide variety of tank and gauge types. The CTM is configurable to work correctly with all available types. In addition, a version of the CTM is available that has an in-line connector on the end of sensor cable. This enables the CTM to work on large bulk tanks with large remote ready dials using the standard sensor manufactured by Rochester Gauges, or the Precision Large Dial Sensor manufactured by Independent Technologies, Inc. Cellular Signal The CTM must be installed in a location served by GSM based cellular service. GSM is a very widely deployed type of digital cellular service – two of the largest service providers are AT&T and T-Mobile. The CTM is supported by both of those major carriers and by a number of other smaller regional cellular service providers. The CTM has a robust cellular sub-system, but there are limits to the capabilities of the cellular network in general. As with most wireless technologies, cellular signal reception can be affected by obstructions such trees, mountainous terrain, buildings, large vehicles parked nearby, etc. In addition, cellular signal reception will be directly affected by the distance between the CTM and the nearest cell tower with GSM service. The best signal reception will be achieved with a line of sight path between the CTM and the cell tower. Obviously, this is rarely the case in the real world, but it should be kept in mind when selecting a mounting location for the CTM. Elevation can also help; typically performance will increase as the CTM is raised higher above the ground. The orientation of the CTM itself will also affect performance. The CTM should be installed upright, and if possible, with the sensor cable exit from the CTM enclosure pointed AWAY from the nearest cell tower supporting GSM service.

WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 7 06/16/2011 Host Information The customer information, installation location, and tank configuration for the proposed installation site must be entered into the WESROC® RMS Host System (Host) BEFORE the CTM is installed on the tank. A WESROC® RMS Installation Information Worksheet outlining the required information fields is available from your host administrator or from Independent Technologies, Inc. Email or fax the completed worksheet to the host administrator before beginning the installation. Installation information can also be called in verbally provided your host administrator considers this an acceptable method. Installation Steps Performing the installation steps in the order shown will help ensure proper operation of the CTM. A large percentage of “trouble sites” are caused by improper installation. 1] If possible, perform a site visit to the location of the tank to be monitored. Determine the size of the tank and the type of gauge on the tank. This will help you select the right equipment to bring with at installation time. This is also a good time to try to determine if you have GSM cellular service available. Access to a GSM cell phone can help with checking for the presence of a usable GSM cellular signal. 2] Send a completed WESROC® RMS Installation Information Worksheet to your host administrator. Try to do this at least one day BEFORE you intend to perform the actual installation so that the host administrator has time to enter the information into the Host. 3] After receiving a Base ID from the host administrator, put the CTM into Configuration mode and enter the 12 digit Base ID into the CTM using the System Configuration screen on the PDU. The Base ID is a unique number that identifies this particular CTM and installation site in the Host. 4] If not already done, install the correct remote ready dial or large dial assembly on the tank gauge. This step is covered in more detail in the WESROC® RMS Dial Replacement Guide available from Independent Technologies, Inc. 5] Remove the CTM from the box and make sure it is the right type for your application. Make sure the small round programming magnet is secured in the OFF position on the CTM enclosure. This is important to ensure proper operation of the CTM when you are ready to perform the first report to the Host. 6] Mount the CTM directly on or near the tank to be monitored. The maximum distance from the tank will be determined by the length of the sensor cable on the particular type of CTM that you are using. The CTM may be mounted to the steel surface of the tank using the mounting magnets on the bottom of the CTM. Another option is to mount the CTM to a pole or another nearby structure using a right-angle mounting bracket. Mounting brackets can be obtained from Independent Technologies, Inc. Try not to place the CTM right next to a metal object such as a tank dome or hood. Metal objects tend to have a negative effect on cellular signal quality.

WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 8 06/16/2011 7] Connect the sensor at the end of the sensor cable to the remote ready dial. This is accomplished by sliding the sensor into the sensor slot on the top of the dial. Slide the sensor from the side towards the center of the dial until it is fully seated. You will hear or feel a small “snap” once it is fully seated. To remove the sensor from the dial, gently lift up on the end of the sensor before attempting to slide it out of the dial. Large dial installations use an in-line connector to attach the CTM to the dial. When attaching an in-line connector, make sure the connector is fully seated and that the locking ring has been turned to ensure a weather tight seal. 8] (Optional.) If you are going to be using a WESROC® RMS Base Unit (Base Unit) as a local display device, now is the time to initialize the CMT to the Base Unit. See section “Operation” of this document for details. The Local Display configuration parameter on the CTM must be enabled for this feature to work. 9] This step assumes that the installation site information has already been entered into the Host and that this particular installation does not require any unusual configuration of the CTM. Remove the programming magnet from the OFF position on the CTM enclosure and step away from the CTM. (Do not degrade the CTM cellular signal quality by leaning over it while it is attempting to report.) At this time, the CTM will attempt a configuration report to the Host. The report is typically completed in about 30 seconds, but can take up to 3 minutes to complete under adverse cellular signal conditions. The CTM does not provide any direct feedback regarding report success or failure; therefore it is highly recommended to make use of a handheld WESROC® RMS Portable Diagnostic Unit (PDU) when performing CTM installations. The PDU will provide the installer with a wealth of information regarding report status, tank level status, CTM system status, and cellular network performance. See section “Portable Diagnostic Unit” of this document, or the WESROC® RMS Portable Diagnostic Unit Operation Manual for more information on operating the PDU. Another option for checking report status is to have the Host send a text alert message to the installer’s cell phone once a successful report has completed. This of course requires that the host administrator enter the installer’s texting address into the Host before installation time. Once installation is completed, the installer will want to have their texting address taken off of the alert list for this site to prevent the Host from sending the installer future tank activity alerts. 10] Once a successful report has completed, secure the sensor cable using appropriate fasteners (cable ties, etc.). Route the sensor cable to make sure the cable will not be damaged by a moving object such as a tank dome or hood. Before leaving the installation site, make sure any programming magnets are removed from the CTM enclosure. Normal operating mode is with NO programming magnets installed.

WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 9 06/16/2011 Operation General After the WESROC® RMS Cellular Tank Monitor (CTM) has been installed on the tank to be monitored; it will periodically report tank level and activity data, and system status information to the WESROC® RMS Host System (Host). Reports can be triggered by expiration of a scheduled report interval timer, or by tank level events or conditions. Operating Modes The CTM has four basic operating modes, only one of which is used during normal operation. The three other modes are used for installation, configuration, or storage purposes. The four modes are selected by the installer using one or two small round programming magnets. The magnets are placed in the programming magnet recesses on the sides of the CTM enclosure when selecting different operating modes. One programming magnet is supplied with each CTM – it is recommended to keep a few extra magnets on hand for use when configuring a CTM. OFF Mode: (One programming magnet in OFF position.) Off mode is used for storage of the CTM. This is the mode the CTM will be in when shipped from the factory. When in Off mode, the CTM will wake up once per second and check the position of the programming magnets. If the installer has moved the programming magnet position(s) the CTM will switch to the newly selected mode. If not, the CTM will resume sleeping for another second. Always leave the CTM in the Off mode to minimize battery drain and to minimize cellular data charges when a CTM is not in use. NORMAL Mode: (No programming magnets.) Normal mode is used while the CTM is monitoring the level of the tank. This is the default operating mode of the CTM once it has been installed. While in this mode, the CTM will wake up once per minute and measure the level of the tank contents. The CTM will then go back to sleep or will take the appropriate action if the tank level has

WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 10 06/16/2011 changed since the last measurement. Actions may include starting or ending the qualification of a tank level event, reporting a tank level event to the Host, or reporting to the Host at a scheduled report time. While in Normal mode, the CTM is also constantly monitoring itself for any conditions that may require reporting to the Host. The CTM will also simulate a WESROC® RMS Tank Transmitter and will send data packets to a Base Unit while in this mode if the Local Display configuration parameter has been enabled. INITIALIZATION Mode: (One programming magnet in INIT position.) Initialization mode is used for initializing the CTM to a WESROC® RMS Base Unit (Base Unit) before using the Base Unit as a local tank level display device. Once the CTM has been put into Initialization mode, it will simulate a WESROC® RMS Tank Transmitter and will send an initialization data packet to the Base Unit once every 15 seconds (or sooner if the tank level changes.) The CTM will time out of Initialization mode and will revert to the Normal operating mode after 60 minutes. This is done to conserve battery life and to ensure that the CTM continues reporting to the Host once the installer has left the site. See the operating manual for the type of Base Unit that you are using for instructions on putting the Base Unit into Initialization mode. CONFIGURATION Mode: (One programming magnet in both OFF and INIT positions.) Configuration mode is used to change one or more of the internal CTM configuration parameters. When in this mode, system (CTM) or application (tank level) operating characteristics can be changed using a PDU. Changes made with a PDU are reported to the Host once the CTM is returned to Normal mode. If field configuration is enabled in the Host, the Host will store the changes to its configuration database, and will send the changes back to the CTM to confirm acceptance of the changes. If field configuration is not enabled in the Host, the Host will overrule the CTM and will send the previous configuration back to the CTM. The CTM will time out of Configuration mode and return to Normal mode if it has not received a configuration command from the PDU for 10 minutes. This is done to conserve battery life and to ensure that the CTM continues reporting to the Host once the installer has left the site. Reporting To Host The CTM reports to the Host on a schedule determined by the Host configuration. The reporting schedule can range from once per hour to once per month. The report interval will directly affect battery life as the cellular sub-system is the major consumer of power in the CTM. It is not recommended to leave the CTM configured with an hourly reporting schedule for more than 24 hours as it will shorten battery life and will lead to excessive cellular data charges. In addition to scheduled reporting, the CTM will contact the Host to report CTM configuration changes, tank level events, and high or low temperature conditions.

WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 11 06/16/2011 Tank Level Measurement The CTM wakes up and measures the level of the tank contents once per minute. This enables the CTM to be very responsive to changing tank level conditions and to more accurately qualify events such as tank fills or tank draws. The tank level is reported in a number ranging from 0 to 99, representing the tank level in percent full. This is the predominant measurement unit in the propane industry, and also serves well when monitoring low pressure fuels such as gasoline, diesel fuel, heating oil, etc. Tank Level Events and Conditions The CTM tracks and qualifies a number of different tank level events and conditions. Qualification of a tank level event or condition will cause the CTM to report to the Host ahead of its scheduled report time. A tank level event such as a tank fill is a one time event and will be reported and then cleared from the tank status. A tank level condition such as a low tank level will be reported, but will not be cleared from the tank status until the condition is no longer true. The following is a summary of the tank level events and conditions supported by the CTM. The configuration parameters referred to in this section can be referenced in the “Application Configuration” section of this document. Tank Fill Event: A tank fill event will be qualified by the CTM when the tank level increases by the configured amount. Tank Draw Event: A tank draw event will be qualified by the CTM when the tank level has decreased by the configured amount within one hour. A tank draw event will NOT be qualified if the tank level has dropped to 0% (bad or missing sensor). Tank Level Change Event: A tank level change event will be qualified by the CTM when the tank level has moved above or below the configured tank level change threshold since the last report to the Host. This threshold can be positive or negative, depending on if the user is looking to track a rising or falling tank level. Tank Critical High Condition: A tank critical high condition will be qualified by the CTM when the tank level has risen above the configured tank critical high threshold. Tank Warning High Condition: A tank warning high condition will be qualified by the CTM when the tank level has risen above the configured tank warning high threshold. Tank Warning Low Condition: A tank warning low condition will be qualified by the CTM when the tank level has dropped below the configured tank warning low threshold.

WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 12 06/16/2011 Tank Critical Low Condition: A tank critical low condition will be qualified by the CTM when the tank level has dropped below the configured tank critical low threshold. Missing Sensor Condition: A bad or missing sensor condition will be qualified by the CTM when the tank level has dropped to 0% for a pre-determined amount of time. The qualification of this condition is not configurable. Temperature Alarms The CTM contains an accurate temperature measurement device and can be used to track ambient temperature at the installation site. The CTM also has configurable high and low temperature alarms and can be used to report abnormal temperature conditions to the Host. The CTM will report a new high or low temperature alarm to the Host, and will also report to the Host once the high or low temperature condition no longer exists. Keep in mind that measured temperatures will be greatly affected by direct sunlight and somewhat affected by night time thermal radiation from the tank if installed on top of the tank. Low Battery Notification A low battery condition will not immediately trigger a report to the Host, but it will set a CTM system status flag that will be picked up by the Host at the next scheduled or event report.

WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 13 06/16/2011 Portable Diagnostic Unit General The handheld WESROC® RMS Portable Diagnostic Unit (PDU) is used to configure and monitor the status of the WESROC® RMS Cellular Tank Monitor (CTM). This valuable device should be considered an essential part of any installation tool kit. The following is a summary of the sections of the PDU interface that are designed for use with the CTM. A more detailed description of the operation of the PDU can be found in the WESROC® RMS Portable Diagnostic Unit Operation Manual. A configuration data packet is required to be transmitted by the CTM before the PDU can be used to configure the CTM or view detailed data from the CTM. The CTM will transmit a configuration data packet before and after each report to the Host, when the CTM is placed in Configuration mode, and each time a configuration command is received from the PDU. The CTM must be in Configuration mode to respond to configuration commands sent by the PDU. A configuration command is sent from the PDU to the CTM each time the user changes a configuration parameter value and leaves a configuration parameter editing screen.

WESROC® RMS Cellular Tank Monitor - Operation Manual - Independent Technologies, Inc. 72-70-164, Rev. P4 Page 21 06/16/2011 Battery Replacement The WESROC® RMS Cellular Tank Monitor (CTM) uses a field replaceable, intrinsically safe battery pack designed and supplied by Independent Technologies, Inc. The CTM has been designed to operate on a very small amount of power, but eventually the battery pack will need replacement. Because the battery pack is intrinsically safe, the battery pack can be replaced at the tank without needing to remove the CTM to a safe location. The following steps and photos illustrate how to replace the battery pack. 1] Remove the eight screws from around the perimeter of the battery pack. 2] Remove the battery pack from the bottom of the CTM enclosure and disconnect the battery pack connector. 3] Connect the new battery pack to the CTM and arrange the battery pack cable to clear internal obstructions. 4] Replace the battery pack into the bottom of the CTM enclosure and replace the eight screws. Do NOT over tighten the screws and strip the threads from the bottom of the CTM enclosure.
