Up-to-date address information is available on our website. smarIntroduction III INTRODUCTION LD301 is a smart pressure transmitter for differential, absolute, gauge, level and flow measurements. It is based on a field-proven capacitive sensor that provides reliable operation and high performance. The digital technology used in LD301 enables the choice of several types of transfer functions, an easy interface between the field and the control room and several interesting features that considerably reduce installation, operation and maintenance costs. Besides all the functions offered by other smart transmitters, LD301offers the following functions: 3)(P - used for trapezoidal weirs in open channel flow measurement.

2 5)(P - used for V-notch weirs in open channel flow measurement. TABLE - the pressure signal is linearly customized according to a 16-point table, enabling, , level-to-volume conversion of a horizontal cylindrical tank. CONTROLLER - the Process Variable is compared to a set point. The deviation acts on the output signal according to an optional PID algorithm. PID OUTPUT CHARACTERIZATION - the PID output signal (MV) follows a curve that is determined by 16 points, which can be freely configured BIDIRECTIONAL FLOW FUNCTION - used to measure the flow in the piping in both directions. LOCAL ADJUSTMENT - not Only for Lower and Upper value, but input/output function, operation mode, indication, set point, PID parameters (optional) as well. PASSWORD - three levels for different functions. OPERATION COUNTER - shows the number of changes in each function. TOTALIZATION - flow totalization in volume or mass.

3 USER-UNIT - indication in engineering unit of the property actually measured, , level, flow or volume. WRITE-PROTECT - via hardware Get the best results of the LD301 by carefully reading these instructions. Smar pressure transmitters are protected by patents 6,433,791 and 6,621,443. LD301 Operation and Maintenance Instruction Manual IV NOTEThis manual is compatible with VERSION , where 6 notes software VERSION and XX software release. The indication means that this manual is compatible with any release of VERSION 6 software WARNING To ensure that our products are safe and without risk to health, the manual must be read carefully before proceeding and warning labels on packages must be observed. Installation, operation, maintenance and servicing must only be carried out by suitably trained personnel and in accordance with the Operation and Maintenance Instruction Manual.

4 Waiver of responsibility The contents of this manual abides by the hardware and software used on the current equipmentversion. Eventually there may occur divergencies between this manual and the equipment. Theinformation from this document are periodically reviewed and the necessary or identified correctionswill be included in the following editions. Suggestions for their improvement are welcome. Warning For more objectivity and clarity, this manual does not contain all the detailed information on theproduct and, in addition, it does not cover every possible mounting, operation or maintenancecases. Before installing and utilizing the equipment, check if the model of the acquired equipment complieswith the technical requirements for the application. This checking is the user s responsibility. If the user needs more information, or on the event of specific problems not specified or treated inthis manual, the information should be sought from Smar.

5 Furthermore, the user recognizes that thecontents of this manual by no means modify past or present agreements, confirmation or judicialrelationship, in whole or in part. All of Smar s obligation result from the purchasing agreement signed between the parties, whichincludes the complete and sole valid warranty term. Contractual clauses related to the warranty arenot limited nor extended by virtue of the technical information contained in this manual. Only qualified personnel are allowed to participate in the activities of mounting, electrical connection,startup and maintenance of the equipment. Qualified personnel are understood to be the personsfamiliar with the mounting, electrical connection, startup and operation of the equipment or othersimilar apparatus that are technically fit for their work. Smar provides specific training to instruct andqualify such professionals.

6 However, each country must comply with the local safety procedures,legal provisions and regulations for the mounting and operation of electrical installations, as well aswith the laws and regulations on classified areas, such as intrinsic safety, explosion proof, increasedsafety and instrumented safety systems, among others. The user is responsible for the incorrect or inadequate handling of equipments run with pneumaticor hydraulic pressure or, still, subject to corrosive, aggressive or combustible products, since theirutilization may cause severe bodily harm and/or material damages. The field equipment referred to in this manual, when acquired for classified or hazardous areas, hasits certification void when having its parts replaced or interchanged without functional and approvaltests by Smar or any of Smar authorized dealers, which are the competent companies for certifyingthat the equipment in its entirety meets the applicable standards and regulations.

7 The same is truewhen converting the equipment of a communication protocol to another. In this case, it is necessarysending the equipment to Smar or any of its authorized dealer. Moreover, the certificates aredifferent and the user is responsible for their correct use. Always respect the instructions provided in the Manual. Smar is not responsible for any lossesand/or damages resulting from the inadequate use of its equipments. It is the user s responsibility toknow and apply the safety practices in his country.
