    SITRANS LUT400 comes with extensive control and alarm functions described below. General introduction Three relays are provided on the SITRANS LUT400. Each relay may be independently assigned to one function (one or more functions for alarms), and has a corresponding status icon on the LCD.

    HART, contact your Siemens representative. Discrete Inputs SITRANS LUT400 has two discrete inputs to trigger or alter the way SITRANS LUT400 controls devices. A Backup Level Override, Pump Interlock, or a Switch (DI) Alarm can be configured using discrete inputs, and discrete input logic can be reversed if necessary for the application.
  • Page 78: Level Override Conditions

    Pump Interlocks Discrete inputs can be used to supply pump information to the SITRANS LUT400 to set actions that will occur when a pump is determined to be in a failed state. Pump Control Interlocks For an example of how to configure a pump interlock, see page 87.
  • Page 79: Discrete Input Logic

    Discrete Input Logic Discrete input logic affects the reaction of the discrete input. Normal state is standard operation, with the SITRANS LUT400 sensing the material level and controlling the pumps. The contacts of the signalling device connected to the discrete inputs may be normally- open or normally closed.

    If the preceding remedies have not fixed the problem, the false echo has to be ignored. If the Echo is Close to the Transducer If there is a static, incorrect, high level reading from the SITRANS LUT400 there is probably something reflecting a strong echo back to the transducer.

Therefore, even if the echo drops below the tvt curve, it can be identified with near certainty for approximately 30 seconds.

    Distance Measurement Range Near Range Near Range (2.2.4.) programs SITRANS LUT400 to ignore the area in front of the transducer. The default blanking distance is 27.8 cm (0.91 ft) from the sensor reference point. Near Range allows you to increase the blanking value from its factory default. But Shaper Mode (2.12.3.4.) is generally recommended in preference to extending the blanking...

    The sound velocity of the transmission medium is affected by the type, temperature, and vapor pressure of the gas or vapor present. As preset, the SITRANS LUT400 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).
