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.

The SITRANS LU01 is an ultrasonic long-range level monitoring system for liquids and solids. SITRANS LU01 level monitor uses one Siemens Milltronics ultrasonic transducers (ordered separately) to accurately monitor material levels without material contact.

The SITRANS LU01 transmits electronic pulses to each connected ultrasonic transducer. The transducer converts the electronic pulses to ultrasonic pulses which are emitted from the transducer face in a narrow beam. The SITRANS LU01 measures the time from the pulse emission, to reception of the reflection (echo) from the material. Using the time measured, the SITRANS LU01 calculates the distance from the transducer face to the material.

The distance calculation depends upon the sound velocity within the vessel. When an Echomax transducer is used, variable air temperatures are automatically compensated. For superior air temperature compensation, a Siemens Milltronics TS-3 temperature sensor may be used for each vessel. A simple calibration feature compensates for homogeneous atmospheres other than air.

The SITRANS LU01 uses Siemens Milltronics patented Sonic Intelligence®echo processing. Sonic Intelligence provides high measurement reliability, regardless of changing conditions within the vessel monitored. By using ultrasonic echo ranging principles with Sonic Intelligence and velocity compensation, the SITRANS LU01 provides outstanding measurement accuracy, usually within 0.25% of range.

Introduction

The distance calculation can be converted to space, material level, material volume, or remaining vessel capacity. The reading chosen (and operating data) for each vessel is displayed on the LCD (liquid crystal display).

The relays and mA outputs may be used as preset (or programmed as desired) to activate alarms and/or operate remote monitoring equipment and/or process control equipment.

RS-232 or 485 (local)

With the addition of a Siemens Milltronics Smartlinx ® protocol specific plug-in communications module, the SITRANS LU01 is compatible with popular industrial control

system standards. Supported protocol include PROFIBUS DP, Allen-Bradley®1 Remote I/O, Modbus® RTU, and DeviceNetTM.

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.

•Dolphin Plus allows programming either through the RJ-11 port or hardwired via the RS-232/485 communication port.

•This product is susceptable to electrostatic shock. Follow proper grounding procedures.

Transducer Mounting

Objects near the transducer face cannot be reliably detected. Mount the transducer above the highest material level (away from the nearest monitored object) by the following Nearest Distance.

Nearest Distance	Transducer Types
0.5 m (1.65 ft)1	ST-H, ST-25, XRS-5, XCT-8, XCT-12, XPS-10, XPS-15, ST-50

1.32m (4.33 ft)	LR-13, XLT-60, XLS-60

1. This is the recommended minimum distance. However, it can be reduced under certain circumstances. Please check the appropriate transducer manual for details.

Interconnection

Before interconnecting system components to the SITRANS LU01 terminals, verify all components have been installed in accordance with the associated product instruction manuals.

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.

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.

Synchronize the SITRANS LU01 with another SITRANS LU01

1.Mount the level monitors together in one cabinet.

2.Ensure the level monitors share a common power (mains) supply, and ground (earth).

3.Interconnect the SYNC terminals of the level monitors to be synchronized.

Note: To synchronize the SITRANS LU01 with other Siemens Milltronics ultrasonic level monitors, contact Siemens Milltronics or your local distributor.

Programming

Operator programmable features are identified by a Point Number and Parameter Number. The Index refers to the Relay Number as identified by the Index Type indicators. Parameter Numbers have a preset Parameter Value for each Index Number.

Program the SITRANS LU01 to obtain the desired RUN mode operation.

Display

In PROGRAM mode, the Index Type, Index Number, Parameter Number, and Parameter Value (as well as a variety of other programming information) may be viewed.

Note that many indicators are specific to certain programming conditions and therefore, all indicators are not displayed at any given time.

Program Mode Entry

Upon initial power application, the SITRANS LU01 displays OFF.

To enter PROGRAM mode

1.Secure the enclosure lid using the 6 captivated screws.

2.Place the infrared programmer in the enclosure lid recess.

3.Press PROGRAM and then press DISPLAY .

When PROGRAM mode is entered after RUN mode operation, all operating data is retained in memory. Relay status and mA output values are held at last known values (unless affected by a parameter alteration or transducer firing) until RUN mode is reentered. RUN mode is automatically re-entered if the SITRANS LU01 is left unattended in PROGRAM mode for an extended period.

Changing Parameters

Enter the new value, and press ENTER . The SITRANS LU01 interprets the value, either accepting or replacing it with a valid value.

1.Starting in RUN mode, press PROGRAM and then press DISPLAY to put the unit into PROGRAM mode.

2.Press DISPLAY to select the Parameter Number field.

3.Key in the desired Parameter Number, or press SCROLL or as required . After the third digit is entered, the parameter value is shown.

(By default, the SCROLL arrows show only the Quick Start Parameters and any that have been changed).

4.Press DISPLAY as required to underline the Index display field.

5.Key in the desired Index or press SCROLL or as required. To alter the Parameter Value for all Indices at once, select Index 00.

Enter the new value, and press ENTER . The SITRANS LU01 interprets the value, either accepting or replacing it with a valid value. .

Notes:

•Record each Parameter Value alteration on the appropriate Programming Chart for future reference, (especially should complete reprogramming be required).

•If Parameter Value alteration is not permitted, access the Lock parameter (P000) and enter the security code (See Programming Security).

Programming

Parameter Reset Features

On initial power up, all parameters are at default values. In many cases, when a Parameter Value is altered, associated Parameter Values are automatically altered accordingly. When a Parameter Number is accessed, if the preset Parameter Value displayed is acceptable, no entry is required.

To return an operator adjusted Parameter Value to the preset value, with the appropriate Index and Parameter Number displayed press CLEAR and ENTER .

To reset all parameters to preset values, use Master Reset (P999).

Note: Perform a Master Reset (P999) if the SITRANS LU01 was bench tested using arbitrary Parameter Values before system installation, following an EPROM replacement, or whenever complete reprogramming is required.

Parameters Types

View Only Parameters

Parameter values indicating status only. They cannot be altered.

Global Values

Parameter values common to all inputs and outputs on the SITRANS LU01.

When a global parameter is accessed, the index display automatically disappears. When a non-global parameter is accessed, the index display reappears showing the last index number.

Parameter Indexing

To set all indexed values for a parameter to the same value, use index 0.

Programming Security

All operator programming is retained in non-volatile memory, immune to power interruptions. When programming is complete, the programmer may be removed and locked away to prevent inadvertent programming alteration. Use the Lock (P000) parameter to secure the SITRANS LU01.
