  • Page 23: Transducer (Sensor)

    Transducer (Sensor) Locating the Sludge Transducer  Position the transducer at an elevation in the tank such that it is fully submerged at all times that measurements are required, typically the face of the transducer should be 150mm below the normal water level. The temperature compensation will only function correctly if the transducer is submerged at this level or below.

  • Page 24: Wall Mount Unit

    Avoid locating the processor near variable frequency drives or other high voltage equipment or cables.  Ensure that the Sludge Finder 2 controller is installed in a “Safe”, non- hazardous, area.  For a clear view of the LCD display it is recommended that it is mounted at eye level.

  • Page 26: Preparation For Operation

    The correct PPE should be worn to ensure you do not come into direct contact with the wetted parts of the Sludge Finder 2 system, if in doubt contact your site Health and Safety Officer.
  • Page 27 The transducer can then be safely inspected for damage or material fouling and can be carefully cleaned with a damp cloth to remove any foreign debris. Care should be taken not to move the wiper by hand as any movement not under the power of the motor may damage the unit.
  • Page 28 The wiper arm will move twice every 20 mins as a default setting, if the face of the transducer is dirty and you are unsure as to whether or not the wiper is cleaning then place the transducer such that the wiper movement will not foul on anything and use the appropriate function key ( ) to force a wipe (see note below).

  • Page 34: Transceiver Mounting

    Transceiver Mounting The Sludge Finder 2 transceiver is mounted in an IP65 rated enclosure. These enclosures are often situated out in the open on the walkways or bridges of settlement tanks and are therefore very exposed to the elements. With this in mind we offer a metal enclosure similar to the one below to ensure that, if required, the unit is not mounted in direct sunlight and is sheltered from any potential exposure to water ingress via precipitation or the application itself.

  • Page 35: Cabinet Mounting

    Cabinet Mounting. If the Sludge Finder 2 transceiver is mounted into the steel cabinet, Pulsar can offer the necessary metalwork to affix the cabinet to a bridge or walkway as seen below. This includes 2 x slotted galvanised steel rails and 4 x U-bolt fittings (customer specified diameter).

    (auto/manual hard/soft) will also be shown at the bottom of the screen. There are two main operating modes for your Sludge Finder 2, Run Mode and Program Mode. There is also a Test Mode, used for checking the set-up. All modes are now described.

  • Page 56: Run Mode

    Run Mode This mode is used once the Sludge Finder 2 has been set up in program mode. It is also the default mode that the unit reverts to when it resumes operation after a power failure. When Sludge Finder 2 is switched on for the first time, it will display, in metres, a level measurement relating to the default tank dimensions.

  • Page 58 Relays The relays screen indicates the current state of all relay outputs and gives a visual representation of the current interface level and the on and off setpoints of the individual relays. The level icons, e.g. “ ” (point 1), represent the level reading of the transducer that the corresponding relay is assigned to (see table below).

  • Page 59: Program Mode

    Program Mode This mode is used to set up the Sludge Finder 2 or change information already set. You must use the built-in keypad to access program mode. Alternatively the unit can be set up with a PC via the RS 232 Serial Interface.

  • Page 64: Using The Menu System

    There are two means of editing parameters, directly or using the menu system. Each is now described. Using the Menu System The menu system has been designed to make the changing of parameters very simple. There are two levels of menu: Main Menu and Sub Menu. At the top of the display there is a line of text that displays the main menu items.
  • Page 65 Once you have reached the relevant section, scroll down the parameter list to highlight the parameter you wish to edit and press ENTER to access the parameter options. When you are at parameter level, the options for that parameter will be displayed on the screen.

  • Page 66: Test Mode

    Test Mode Test mode is used to simulate the application and confirm that all parameters and relay setpoints have been entered as expected. During simulation, there is a choice of whether the relays will change state (hard simulation) or not (soft simulation), but the LED’s will always change colour as programmed, and the mA outputs will change in accordance with the chosen mode of operation.

  • Page 67: Using The Rs232 Serial Interface

    To use the device remotely, you need to log on to start, and log off when finished. When logged on, Sludge Finder 2 will show “Remote” on the display in place of the clock. When logged off, the display will return to normal (clock will be displayed).
  • Page 68 To read a parameter value, send the command /Pxxx where xxx is the parameter you wish to read, and the Sludge Finder 2 will respond with the parameter value. To set a parameter, send the command /Pxxx:yy where xxx is the parameter number, and yy is the value you wish to set it to.

Option Description 0= Off mA output disabled. 1= 0 to 20 mA mA output directly proportional to the mA mode (P831/P891), so if the reading is 0% the output is 0 mA.

  • Page 114: Setpoints

    Setpoints By default the mA Output will represent the empty (0 or 4mA dependant on (P830/P890) mA Range) and 100% of the operational span (20mA), but you may wish to have the output represent a section of the operational span. For example, the application has an operational span of 6 metres but output is to represent empty (0 or 4mA dependant on (P830/P890) mA Range) to a level of 5 metres (20mA).

  • Page 128: Test Parameters

    Test Parameters Simulation P980 Simulate Test mode is used to simulate the application and confirm that all parameters and relay setpoints have been entered as expected. During simulation, there is a choice of whether the relays will change state (hard simulation) or not (soft simulation), but the LED’s will always change colour as programmed, and the current output will change.

  • Page 129: Hardware

    P983 Start Level When using automatic simulation this parameter can be used to pre-determine the point at which the simulated level will start at and return to. This can be used to simulate the lowest point to which the level would normally operate. Hardware P990 Self Test If you enter 1 for this parameter, then the unit will perform a self-test.
  • Page 130 P997 Keys Test You should press each key, to confirm it works, with a counter showing how many more keys you have to press. Press the CANCEL key last, as this will confirm if all keys were pressed or not. If they were not, then an error message is displayed. P998 Relays Test Press a numeric key corresponding to the number of the relay you wish to test, and the relay will change state each time the key is pressed.
