  • Page 7: Introduction

    Introduction SITRANS LU01 Note: • The SITRANS LU01 is to be used only in the manner outlined in this instruction manual. • This product is intended for use in industrial areas. Operation of this equipment in a residential area may cause interference to several frequency based communications.
  • Page 8 Programming can be done locally using the portable programmer keypad, or remotely through optional Dolphin Plus software or SmartLinx. • The programmer transmits the keypad entries via infrared link to the SITRANS LU01, and can be removed when not in use. •...

  • Page 9: Sitrans Lu01 Features

    SmartLinx provides protocol specific hardware and software for interface with popular industrial communication systems. The SITRANS LU01 is typically used to monitor material level in open or closed vessels but can be used in almost any process which requires a distance measurement (within the system range).

    The following procedure applies to all SITRANS LU01 level monitor installations. See Application Examples on page 89 for additional installation requirements. Also, refer to the instruction manuals of all other equipment connected to the SITRANS LU01 for additional installation instructions.

  • Page 16: Mounting

    Mounting Inspect all cartons and packaging for possible damage during shipment, before removing the SITRANS LU01 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

    Connect all associated equipment cable shields to the SITRANS LU01 shield connections. To avoid differential ground potentials, do not connect cable shields to ground (earth) elsewhere. Insulate or tape cable shields at all shield junctions to prevent ground loops.

  • Page 22: Communication

    Refer to the appropriate SmartLinx manual for installation and wiring. Level System Synchronization Avoid mounting the SITRANS LU01 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 SITRANS LU01 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.

  • Page 91: Technical Reference

    Technical Reference Transmit Pulse The SITRANS LU01 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 SITRANS LU01 terminals.

    The sound velocity of the transmission medium is affected by the type, temperature, and vapour pressure of the gas or vapour present. As preset, the SITRANS LU01 assumes the vessel atmosphere is air at 20°C (68°F). Unless altered, the sound velocity used for the distance calculation is 344.1 m/s (1129 ft/s).

    Velocity (P653) may be entered directly. Volume Calculation The SITRANS LU01 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).

The mode of communication is established by the configuration of the connection made at the SITRANS LU01, either RS-232, RS-485 or bipolar current loop. simplex convention The SITRANS LU01 uses communication protocol. Data messages are continuously transmitted at regular intervals (no poll is required) at 4800 baud. All data is transmitted in structured messages of ASCII characters consisting of 8 data bits, no parity, and 1 stop bit.

    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 SITRANS LU01 to lock on to a false echo and report a fixed or wrong reading.

  • Page 107: Fixed Reading

    Sometimes, material simply cannot be detected during vessel filling. In these cases, set up failsafe operation so the SITRANS LU01 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.
