    Chapter 1 Start Here… Congratulations on your purchase of a Pulsar Ultra Twin. This quality system has been developed over many years and represents the latest in high technology ultrasonic level measurement and control. It has been designed to give you years of trouble free performance, and a few minutes spent reading this operating manual will ensure that your installation is as simple as possible.

  • Page 10: About The Ultra Twin

    Ultra Twin sends a transmit pulse to the transducer(s), which emits an ultrasonic pulse perpendicular to the transducer face, and the returned echo is sent back to the Ultra Twin. The time taken to receive the echo is measured and the distance from the transducer face to the surface being monitored is calculated.
  • Page 11 PLC, to monitor level space, distance, volume, OCM head or flow (dependant on the application chosen), independently from that shown on the display. There is an RS232 port, so that the Ultra Twin can be operated remotely by a PC or other equipment.

  • Page 15: Chapter 2 Installation

    Power Supply Requirements Power Supply Requirements The Ultra Twin can operate from AC supply or from a DC battery. The AC is either 85-120V 50/60Hz or 170-240V 50/60Hz, depending on the position of the selector switch. The DC is 18-36V. In all cases the Ultra Twin will typically consume 6W of power, with a maximum of 10W.

  • Page 16: Dimensions

    When choosing a location to mount the enclosure, bear in mind the following: • Ensure that the Ultra Twin 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 17 The Ultra Twin should be mounted by drilling three holes suitable for size 8 screws (length to suit your application), and fixing the top screw in place. Hang the unit on this and fix the two remaining screws by removing the terminals access cover to access the pre drilled holes.

  • Page 18: Fascia Mount

    Cable Entry There are 6 cable gland knockouts on the base of the Ultra Twin (4 x PG11, 1 x PG9, 1 x PG13.5) and 5 on the rear (5 x PG11). Select which ones you wish to take out, and remove them by using a circular cutter, such as a tank cutter.

  • Page 21 Terminal Connections Power The Ultra Twin can operate from mains AC and automatically from DC or battery backup in the event of power failure, or can be operated permanently from DC or batteries. Transducer The transducer should be installed, and connected, in accordance with the installation instructions contained in the Transducer User Guide.
  • Page 22 Digital Inputs Where the Ultra Twin is required to provide power for a Device Input the appropriate Digital Input should be wired between the 24VDC supply terminal and the IN terminal. (TOTAL maximum current available, for all digital inputs, four on Wall Mount model and seven on Fascia Mount model, from the 24VDC supply is 24mA).
  • Page 23 Temperature Input The external temperature sensor allows more localised compensation of the measured distance due to changes in temperature. There are two models, Type A and Type B as follows: Type A -25ºC to 50ºC Type B -25ºC to 125ºC The temperature sensor should be placed close to the point of measurement.

  • Page 25 Please note that all units are supplied set to 230 volts AC for safety reasons. Never operate the Ultra Twin with terminal access exposed. An external switch or circuit breaker should be installed near to the Ultra Twin to allow the supply to be removed during installation and maintenance.

  • Page 26: Preparation For Operation

    Maintenance Maintenance Maintenance There are no user serviceable parts inside your Ultra Twin, except the mains fuse. If you experience any problems with the unit, then please contact Pulsar Process Measurement for advice. To clean the equipment, wipe with a damp cloth. Do not use any solvents on the enclosure.

  • Page 29: Run Mode

    All modes are now described. Run Mode This mode is used once the Ultra Twin 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.

  • Page 30: How To Access Program Mode

    There is a time-out period of 15 minutes when in program mode, after which time run mode will be resumed if you do not press any keys. Once you have entered the program mode the Ultra Twin will automatically access point 1 menu system, and the top display will show “Program Mode”...
  • Page 31 Run Mode. Pressing the hot key once will display the first parameter, then repeated pressing will display the others, then the Ultra Twin reverts to Run Mode. In program mode, they have different functions, the functions are shown below.
  • Page 32 1) Used to confirm each action (for example select a menu option) or when entering a parameter number or value. 2) Used to confirm questions asked by your Ultra Twin such as before restoring factory defaults. Used to navigate up a level in the menu system, and back to run mode.
  • Page 33 The main or top menu is common to both points of measurement and when you first access the program mode your Ultra Twin will display the menu system for point 1. To change form one point to point 2 menu system press hot key, whilst in any Main Menu heading, e.g.
  • Page 34 When you have finished, press CANCEL to go back to the previous level. When you have reached the top level, then the Ultra Twin will ask for confirmation before allowing you to go back into run mode. This is done by pressing ENTER at the display prompt.

  • Page 35: Test Mode

    When you are at a parameter, the text line rotates automatically displaying the parameter name, number, the applicable units and the maximum and minimum figure you can enter. The top line shows the value you are setting. Once you have accessed a parameter, you can either just look at it, or change Once a parameter has been changed, press ENTER and you will see the message “Saved!”.

  • Page 36: Parameter Defaults

    Factory Defaults P*930, as described in the relevant unit type parameter guide. When you first switch the Ultra Twin on, it will be reading the distance from the face of the transducer to the surface. It will be indicating in metres, as shown on the display.
  • Page 37 Once you are satisfied with the installation, and the Ultra Twin is reading what you would expect in terms of distance from the face of the transducer to the material level, then you can proceed with programming, for the intended application. It is sensible to program all of the required parameters at the same time.

    Important Information When mA Output 1is to be representative of the average or sum of two points of measurement, then both points must be set to the same units of measurement. In the case of flow P1-100 and P2-100 are set for 4 (OCM Head) or 5 (OCM Flow), then P1-706, P2-706 (Volume Units) &...

    Temperature P1 or P2 P1-852, P2-825 Temperature Source This parameter determines the source of the temperature measurement. By default it is set to automatic (P1-852, P2-852=1), which will automatically detect if a temperature sensor is available from the transducer. If for any reason, no temperature input is received, then the Fixed Temp value is used, as set by P854.

    Test Parameters Test Parameters Test Parameters Test Parameters Simulation P1 or P2 P1-980, P2-980 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 181: Test Setup

    Test Setup P1 and P2 P*981Increment By default, simulation mode will move by 0.10m steps in manual simulation and by 0.25m/min in automatic simulation. Altering the increment can change this value. P*982 Rate In automatic mode, the rate at which the level will move up and down, is determined by distance, P*981 Increment and the time, P*982 Rate which by default is set to 1min and can be changed as required.
  • Page 182 P*991 Hard Test When this parameter is selected, the unit will test the following in turn. • LED’s. Watch them change colour as shown on the display, and press, ENTER, if they operated as shown. • Relays. 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.
