  • Page 7: Description

    Each pulse is reflected as an echo from the material and sensed by the transducer. The device processes the echo using Siemens’ proven Sonic Intelligence techniques. Filtering is applied to help discriminate between the true echo from the material and the false echoes from acoustical and electrical noises and agitator blades in motion.

  • Page 10: Mounting Instructions

    Mounting instructions Note Ideally, mount the device so that the face of the transducer is at least 250 mm (9.84 inch) above the highest anticipated level. The device is available in three thread types: 2" NPT, 2" BSPT, or 2" G. Before inserting the device into its mounting connection, ensure that the threads are of the same type to avoid damaging them.

The certification of this equipment relies upon the following materials used in its construction: Aluminum alloy T356 T6 (main enclosure) and A356 T6 (lid) GE Lexan 943A polycarbonate Two-part epoxy encapsulant Silicon based coating Santoprene 111-55 gasket Master Bond Polysulphide EP21LPT or Dow Corning 3-4207 encapsulant (transducer) ETFE (transducer) Epoxy syntactic foam (transducer)

  • Page 12: Operating

    5 Operating Startup With the device correctly installed (or aimed at a wall 0.25 to 5 m away), apply power and view the startup sequence. It will light all possible LED values, show product revision number, product model number, and will enter run mode. Then, the display shows the measurement of the distance from the transducer face to the material level in the units indicated.

  • Page 13: Quick Start

    Operation status - run mode Echoes are valid and within range. Echoes are lost due to poor conditions or out of range. This may be typical in applications where there are deep vessels and the material level is normally out of range. Refer to Troubleshooting (Page 38).

    Operating adjustments 5.4.1 Operating adjustments To access the operating adjustments, simultaneously press both keys repeatedly until the desired adjustment is obtained. A viewing period of the adjustment value is initiated. During this time the value can be changed by pressing either the 'up' or 'down' key. After viewing or changing, operation automatically reverts to the run mode.

  • Page 19: Setpoints

    5.4.3 Setpoints The setpoints can be set where reference levels, either from the material in the vessel or from a target, cannot be provided. This meth- od can also be used to trim the output levels obtained by the Reference Method (Quick Start).

  • Page 20: Relay Deadband (Reset)

    5.4.5 Relay deadband (reset) Deadband (hysteresis) prevents relay chatter due to material level fluctuations at the set point. These fluctuations are often waves or turbulence on a fluid's surface caused by agitators in the tank. Once a relay is tripped, the detection level must move beyond the deadband value before it is reset.

  • Page 21: Blanking

    5.4.6 Blanking Blanking is used to ignore the zone in front of the transducer where false echoes are at a level that interfere with the processing of the true echo. It is measured outward from the sensor face. The minimum recommended blanking value is 0.25 m (0.82 ft) but can be increased in order to extend the blanking.

  • Page 23: Speed Of Response

    5.4.8 Speed of response The speed of response adjustment allows the user to collectively set a number of operating parameters. Measurement response Is the limit to which the device is able to keep up with rates of change. If the device measurement cannot keep up with the rate of level change, set the adjustment from 1 to 2.

  • Page 24: Fail-Safe Mode

    5.4.9 Fail-safe mode In the event that a loss of echo condition exceeds the fail-safe timer (speed of response variable), ? appears in the display; and if a relay is assigned to LOE (alarm function option), it is engaged. This function must be used with the Output function (Page 17). Function Fail-safe Mode...

  • Page 27: High Level Alarm Switch

    High level alarm switch Application: an alarm output, high and/or high-high alarm, when the process material rises to a high level. Application Notes: It is common to apply the switch on vessels where the material is normally below the unit's range. Under such a condition the device loses echo, and if prolonged, defaults to fail-safe operation.

  • Page 28: High/Low Level Alarm Switch

    High/low level alarm switch Application: high and low level alarms. Application Notes: If the material can fall below the unit's range, the device loses the echo, and if prolonged, defaults to fail-safe operation. The fail-safe default should be set to suit the application.

  • Page 29: Low Level Alarm Switch

    Low level alarm switch This application uses the device to provide one or two low level alarms. If the material can fall below the unit's range, the device loses the echo, and if prolonged, defaults to fail-safe operation. The fail-safe default should be set to suit the application. Fail-safe = 1, 2, or 3 Fail-safe = 2 or 3 ①...

  • Page 30: Dual Pump Control

    Dual pump control This application uses the device to provide a control output when the process material rises to a high level. Typically, wet wells are used to temporarily hold storm and/or waste water. When the water surface reaches a high level setpoint, the wet well is pumped down. The process material will be pumped down by the deadband value to another setpoint where the control will turn off.

  • Page 31: Pump Control With Level Alarm

    Pump control with level alarm This application uses the device to provide pump control and one level alarm. If the material reaches a control setpoint, the well is pumped down or up respectively. If the material reaches an alarm setpoint, the alarm will sound until the material moves beyond the deadband value.
