  • Page 7: Introduction

    The transducer converts the electronic pulses to ultrasonic pulses which are emitted from the transducer face in a narrow beam. The AiRanger DPL Plus measures the time from the pulse emission, to reception of the reflection (echo) from the material.
  • Page 8 ® With the addition of a Siemens Milltronics Smartlinx protocol specific plug-in communications module, the AiRanger DPL Plus is compatible with popular industrial control system standards. Supported protocol include PROFIBUS DP , Allen-Bradley® Remote I/O, Modbus® RTU, and DeviceNet Programming can be done locally using the portable programmer keypad, or remotely through optional Dolphin Plus software or SmartLinx.

    The following procedure applies to all AiRanger DPL Plus level monitor installations. See Application Examples on page 96 for additional installation requirements. Also, refer to the instruction manuals of all other equipment connected to the AiRanger DPL Plus for additional installation instructions.

  • Page 16: Mounting

    Mounting Inspect all cartons and packaging for possible damage during shipment, before removing the AiRanger DPL Plus and associated equipment. Loosen the 6 enclosure lid (captivated) screws and swing the lid open. Remove the 4 Board B mounting screws (outer corners) and remove the circuit board assembly.

  • Page 17: Interconnection

    Interconnection Before interconnecting system components to the AiRanger DPL Plus terminals, verify all components have been installed in accordance with the associated product instruction manuals. Connect all associated equipment cable shields to the AiRanger DPL Plus shield connections. To avoid differential ground potentials, do not connect cable shields to ground (earth) elsewhere.

  • Page 22: Communication

    Refer to the appropriate SmartLinx manual for installation and wiring. Level System Synchronization Avoid mounting the AiRanger DPL Plus near another ultrasonic level monitor. Likewise, when more than one monitor is installed within a single plant/facility, ensure the transducer cables of each system are run in separate grounded metal conduits. If this system separation is impractical, or if measurement difficulties are encountered, system synchronization may be required.

  • Page 23: Power

    • Never operate the AiRanger DPL Plus with the enclosure lid open, or with the ground (earth) wire disconnected. • Ensure that any associated alarm or control equipment is disconnected until satisfactory operation is verified.

    Technical Reference Transmit Pulse The AiRanger DPL Plus transmit pulse consists of one or more electrical shot pulses, which are supplied to the scanning relay. The scanning relay is activated as required, to supply the transmit pulse to the Transducer(s) connected to the AiRanger DPL Plus terminals.

    Volume Calculation The AiRanger DPL Plus provides a variety of volume calculation features (P050 to P055). If the vessel to be monitored does not match any of the 8 preset Tank Shape calculations, a Universal Volume calculation may be used. Use the level/volume graph or chart provided by the vessel fabricator (or create one based on the vessel dimensions).

  • Page 120: Measurement Difficulties

    If a measurement difficulty occurs for greater than the Failsafe Timer (P070) setting, LOE is flashed alternately with the Reading display. Under certain conditions, a measurement difficulty may cause the AiRanger DPL Plus to lock on to a false echo and report a fixed or wrong reading.

  • Page 121: Fixed Reading

    Sometimes, material simply cannot be detected during vessel filling. In these cases, set up failsafe operation so the AiRanger DPL Plus anticipates the rate of material level increase and adjusts the reported Reading accordingly. This operation is reliable, as long as when the dust (or foam) settles a valid echo can be received.
