You Can Measure the Benefits… Training Course MonoScan Setup & Configuration

You Can Measure the Benefits… MonoScan supplied with preprogrammed default settings, making it ready for immediate use.  Main setting-up steps 0 – 5  Pr 00 – Flow measurement (MonoScan O) This program enables you to select preset weir/flumes. Note: this function will be available only for Open Channel unit. Setup MonoScan 2 wires

You Can Measure the Benefits…  Pr 01 – Reset reset the unit (keeps the last parameters), same as on/off  Pr 02 – Tank height enter the correct height (from sensor to bottom) MonoScan 2 wires Setup

You Can Measure the Benefits…  Pr 03 – Defining interfering signals (Scan Distance process) “ Static interference ” is a well known phenomenon in ultrasound technology. Use Scan Distance function to “ map ” your tank from these obstacles and to memorize the interfering signals. MonoScan 2 wires Setup

You Can Measure the Benefits…  MonoScan can locate and store up to 7 obstructions.  After storing 7 interference signals the memory act as FIFO (first in first out), the 7th signal will erase the first signal and so on. Note:  Each obstruction will extend the calculation time.  Defining interfering signals is done while the tank is empty. MonoScan 2 wires Setup

You Can Measure the Benefits…  Clear stored interferences  When entering Pr.03, you can either select Search to locate acoustic interferences, or Clear to delete stored interferences. MonoScan 2 wires Setup

You Can Measure the Benefits…  Pr mA  Pr mA The 4mA can be defined for Level, Distance or Flow measurements. This definition will be applicable for 20mA values, in Pr.05. MonoScan 2 wires Setup

You Can Measure the Benefits…  When setting 4mA and 20mA for Level measurements, Pr.04 and Pr.05 will be configured for level values.  When setting 4mA and 20mA for Distance or Flow the values will be in Distance or Flow). MonoScan 2 wires Setup

You Can Measure the Benefits… MonoScan 2 wires  Extra Features  Pr 06 Low / High dynamic Define whether high or low reading speed : SE cm/minute (low dynamic) SE m/minute (high dynamic) SE 2 – rapid changes (fast dynamic 2m/min) Note: Pro 06 is available in models L/O, while S uses low dynamic as default. Setup

You Can Measure the Benefits…  Pr 08 To select whether to display distance (from surface) or the level (of the surface)  d000 represents distance reading  L000 represents level reading MonoScan 2 wires Setup

You Can Measure the Benefits… MonoScan 2 wires Setup  Pr.09 – Gas Compensation.  This program enables you to compensate for sound velocity in different types of gasses, provided the sound velocity is fixed.  You can enter the appropriate factor for each type of gas listed on the ‘Gas Table’ in the User Manual.  For example the sound velocity in air is m/sec and for Ethanol (C2H3OH) m/sec, therefore a factor of /331.6= Note: Since there are several gases in the tank, air density must be calculated

You Can Measure the Benefits… MonoScan 2 wires Setup  Gas Compensation – Volume calculation  This program enables the user to calculate volume in a linear tank (cylindrical etc). PR09 factor is multiplied with the measurement value giving a volume up to 1500 (maximum displayed value).  For example tank height = 1.5m  Volume factor = 3  Maximum volume = max T.H. X Volume factor = 1.5 X 3 = 4500  Maximum Gas factor = 10  Volume is calculated linear.

You Can Measure the Benefits…  22mA Error Signal Indications  “ F.F.F.F ” - Whenever the level reaches up to 10cm inside dead zone or overflow occurred, “ F.F.F.F ” will appear on the MonoScan ’ s display.  “ E.E.E.E ” - Whenever the echo is not received by the transducer because of empty tank or when the measured distance is greater than permitted, “ E.E.E.E ” will appear on the MonoScan ’ s display. MonoScan 2 wires Setup

You Can Measure the Benefits…  Enable/Disable 22mA error signal indications, such as: Near Zone (F.F.F.F) and Lost Echo or empty (E.E.E.E).  Default value is disable.  In order to enable it, Enter 0016 in Pr.02. MonoScan 2 wires Setup

You Can Measure the Benefits… Device ’ s version.  Enter 0017 in Pr 02.  After entering this code, the screen Addr (Version) will be displayed.  Enter 0013 in Pr 02.  After entering this code, the screen Addr (sub Version) will be displayed. MonoScan 2 wires Setup

You Can Measure the Benefits…  Shift Blocking Distance (SBD)  This function enables you to enlarge the Dead Zone and is applicable for installations requiring extension pipes or nuzzles positioned above the application level.  SBD is limited to 1.5m/4.9ft.  In order to access this function, enter 0001 in Pr 02. MonoScan 2 wires Setup

You Can Measure the Benefits…  Pr 00 – Flow measurement (MonoScan O) Includes 17 types of Flume/Weirs, each of them is offered at several Sizes. The measured units can be displayed as either GPM or M 3 Per hour. The methodology used when setting up open channel: X – Particular flume/weir type E/U – European/American standard YY- Specific flume/weir dimensions Setup MonoScan 2 wires

You Can Measure the Benefits…  EC11 – Noise  5544 – Sensor disconnected Contact manufacturer for further instructions  E555 – Power supply problem Make sure your power supply corresponds to Solid specification. If problem persists, replace the power supply MonoScan 2 wires Troubleshooting

You Can Measure the Benefits…  A combination of three 8 and one 1 may occurred either due to shortage or when two pads pushed simultaneously.  8188 Back  8818 Next  8881 Enter  1888 Escape Check for any visual damage on Pads. MonoScan 2 wires Troubleshooting

You Can Measure the Benefits…  8888 will appear for a few seconds after restart. If it last more than a few seconds it may be due to the following reasons:  Power supply ’ s voltage is too low  “ Load Resistor ” resistance is too high or not necessary at all  Random Impulse which cause automatically self restart MonoScan 2 wires Troubleshooting
