Advanced Relay configuration: an option to configure relays operation to level, distance or flow modes (currently available in SmartScan50 only). __________________________________________________________________ AN00 SM Rev: - 1.00 Page 5 of 15 ã Copyright Solid Applied Technologies Ltd. 3.1 PART I – NEW SW FEATURES FOR SW VERSIONS 2.05 AND 5.04 OF SMARTSCAN 25 AND 50 (RESPECTIVALY) 3.1.1 4-20MA SIGNAL ERROR MESSAGES General: In previous SmartScan versions, errors were alerted only by displaying an error message according to the list of errors presented in the SmartScan user manual. The new SmartScan version enables the user to use current signaling to present an error on the 4-20mA and on the SmartScan display. Such option is highly popular in applications where the user wants to view errors from a remote station (depending on the capability of the remote station to support this current signaling). Implementation: New configuration program, , added under the . Under the user can set one of the following legal values: 0 – Enables 22mA error current signaling. 1 – Enables 3.7mA error current signaling. 2 – Disables error current signaling. Error messages will appear on screen in the following cases: Near Zone – 'FFFFF' message will be displayed on the SmartScan screen indicating that the measured level is below the defined dead zone. Lost Echo – 'EEEEE' message will be displayed on the SmartScan screen, indicating that the level is below the configured 4mA value or that the echo is lost. Tank Empty – 'EEEEE' will appear on screen indicating that the measured distance is higher than the configured tank height (this is typically to tank with conical ending). Noises/Interferences – 'AUTO' followed by inaccurate reading will appear on screen, indicating that there are noises or other interferences in the unit surroundings that are causing disturbances to the measurement procedure. __________________________________________________________________ AN00 SM Rev: - 1.00 Page 6 of 15 ã Copyright Solid Applied Technologies Ltd. 3.1.2 OPEN CHANNEL STANDARDS General: There are more than few differences between American and European open channel standards. These differences happen as a result of: 1. Different popularity of flumes/weirs types. 2. Different measurement system (meter/feet; M3/GPM). Solid AT implemented this option to enable the user to set the unit to either American or European standard. This option provides approximately 17 different predefined types of flumes/weirs already implemented in the SmartScan memory, which shortens installation time and setup procedure. Once the user selects the desired standard, the parsh.flum coding of flume/weir type and dimensions will be according to the standard he has chosen. Implementation: Consult your local provider to modify the open channel standard from the one currently defined in your SmartScan unit. i Note The user on screen indication symbol will be: · Predefined open channel, American standard: XU.YY. · Predefined open channel, European standard: XE.YY. ‘X’ stands for the flume/weir type and ‘YY’ stands for the flume/weir dimensions, as described in the user manual. __________________________________________________________________ AN00 SM Rev: - 1.00 Page 7 of 15 ã Copyright Solid Applied Technologies Ltd. 3.1.3 NEW FLOW TOTALIZATION FEATURES General: Enabling the totalization mode in SmartScan allows the user to view the actual amount of flow in real time updated every 30 seconds. In the previous SmartScan version the totalization value was not stored in memory and could have been lost in case of power failure. In the new SmartScan version the total accumulative totalization value is stored in memory from the point of activating this mode, and can be retrieved in case of power failure. Implementation: This feature has been implemented under , in the . Until now, setting the totalization mode in SmartScan models was done by selecting . In the new SmartScan SW version, the following options are definable under : 0 – Reset totalization. 1 – Activate totalization. 2 – Deactivate totalization. Totalization values are shown in two separate screens for high and low numbers. High (large) numbers are indicated by H followed by the first five digits of the value; low (small) numbers are indicated by L followed by the last four digits of the value. Toggling between these screens using or buttons allowa the user to view the different totalization values. For example, if the total flow is 147,521 gallons, the user will see 'H00001' in the high numbers screen and 'L47521' in the low numbers screen. __________________________________________________________________ AN00 SM Rev: - 1.00 Page 8 of 15 ã Copyright Solid Applied Technologies Ltd. 3.2 PART II – NEW SW FEATURES AVAILABLE ONLY FOR SMARTSCAN 50 5.06V 3.2.1 DISPLAY INDICATION OPTIONS General: In the past, when setting the SmartScan unit for a certain indication mode, the user could view measurement results only in the selected indication mode. This new SW version enables the user to view obtained measurement results in various types of indication modes. For example, if the user sets the SmartScan unit for distance, he will be able to obtain measurement results in either distance or level. The table below describes the optional indication modes available: Indication Indication Toggle Option Distance/Level Distance/Level Flow Flow/Level/Distance Totalization Totalization(High)/Totalization (Low)/Distance/Flow Volume Volume/Level/Distance Implementation: In the main menu move to select the desired indication and exit the main menu. On the SmartScan default screen, use button to toggle between indication modes. For example, if the user sets the SmartScan unit for volume, the default screen will display the current volume value. By pressing button once, he will be able to view measurement results in Level values, pressing once again will display measurement results in Distance values. i Note The display will return to the default indication mode after 30 seconds. __________________________________________________________________ AN00 SM Rev: - 1.00 Page 9 of 15 ã Copyright Solid Applied Technologies Ltd. 3.2.2 ADVANCED RELAYS CONFIGURATION General: In the new SmartScan50 SW version user can configure relays operation to level, distance, flow, volume and totalization values. Default operation mode for relay configuration is always level, but the user can change it to work with other modes as described above. Here are the optional relays set-up modes: Non Flow Application Flow Application Indication Mode Dist. Level Vol. Flow Totalization Relay Mode Dist., Level Vol. Flow, Dist., Level Flow, Total. For example, when the indication mode is configured for distance or level, the user will be able to configure relay operation values for either distance or level units. When the indication mode is configured for flow values, the user will be able to configure relay operation values for flow, distance or level values. In addition, relay 4 and 5 can be configured to perform other tasks in addition to the normal relay settings. · Relay 4 can be configured to activate an alarm in case the unit produces inaccurate measurement results due to an electrical failure or acoustic problem. · Relay 5 can be configured for flow totalization pulse indication. This option enables the user to receive a pulse indication from the relay per X m³/gallons of flow. Implementation: Option to enter parameters in each of the modes: Level/Distance/Flow. If flow indication mode was selected, relays can be configured to Level/Distance/Flow values. After selecting the relays mode (Level/Distance/Flow) the user will be able to configure Open/Close relays modes. Optionally, the user can configure relay 4 to report errors. The relay will be closed and 'EEEEE' message will appear on screen in case of lost echo or if measurement results are higher than tank height. 'FFFFF' message will be appear on screen in case of near dead zone. In addition, the can configure relay 5 for flow totalization pulse indication. The flow value can be selected from a list of optional values from 1 to 100,000. An electrical pulse will be generated whenever the relay total value will be greater than the value selected from the list. The user can also define a pulse width between 20 to 2000ms with a resolution of 10ms. __________________________________________________________________ AN00 SM Rev: - 1.00 Page 10 of 15 ã Copyright Solid Applied Technologies Ltd. For example, a pulse with duration of 1000ms will be generated each time the value of flow will reach 10,000m³ (if the value that was selected from the optional values list is, 10,000). i Note For safety reasons, relays operational values will reset when the following occurs: · Change of 'tank height'. · Change of measuring mode from Level/Distance to Flow and vice versa. · Change of Relays mode: Level/Distance/Flow. · Change of flume type in Flow mode · Change from solid to liquid mode · Change of measurement units __________________________________________________________________ AN00 SM Rev: - 1.00 Page 11 of 15 ã Copyright Solid Applied Technologies Ltd. 4.
