Description 3.2 Design and principle of operation Principle of operation The basic component in each case is a special type of spring body. The application of force elastically deforms the spring body. The ohmic resistance of the strain gauges changes as a result.

Installing Basic safety instructions Load cells are precision components and must therefore be handled carefully. Particular care must be taken during transport and installation. DANGER Danger to life from falling loads • Load cells are not machine components which have been constructed with the normal safety factors.
The mounting components normally allow so much room for movement that heat expansion will not result in lateral loading. • Protect the load cell against higher impact energy levels by using Siemens mounting accessories. NOTICE Destruction of load cells Proceed carefully with installation.
Installing 4.3 Dismantling Dismantling For dismantling the load cells, the same safety rules apply as for installation. 1. Disconnect all the supply voltages and auxiliary voltages. 2. Secure the load carrier against falling. 3. Use appropriate hoisting gear and tools. 4.
Connecting Basic safety instructions WARNING Insufficient isolation of intrinsically safe and non-intrinsically safe circuits Risk of explosion in hazardous areas. • When connecting intrinsically safe and non‑intrinsically safe circuits ensure that isolation is carried out properly in accordance with local regulations for example IEC 60079-14. •...
Connecting 5.2 Connecting principle Connecting principle Load cells can be equipped with connecting cables with four or six cores. WARNING Risk of explosion Please observe that in the case of shielded cables of intrinsically safe circuits in hazardous areas only one grounding is permissible. If grounding is to be on both sides an equipotential bonding conductor with at least 4 mm²...
Page 27
Connecting 5.2 Connecting principle Load cells with four-wire system Do not shorten or length connecting cables in the four-wire system, because the cable resistance is temperature compensated. When the length of the connecting cable is altered, the input and output resistances change. This change can be corrected by adjusting the scale, but temperature-dependent resistance changes are not compensated for the missing or additional length of cable.
Page 28
Connecting 5.2 Connecting principle Load cells with six-wire system For connecting cables in the six-wire system, the supply voltage is fed back to the weighing module as the reference voltage. Shortening or lengthening has no effect on the measuring result. Figure 5-2 Connecting principle for load cells with six-wire system SIWAREX WL200...

Commissioning 6.2 Application planning Parallel connection of load cells In weighing systems, one or more load cells are connected to a weighing module for evaluation of the measured signal. Several load cells of a scale are connected in parallel to a junction box to supply a joint output signal.
Commissioning 6.2 Application planning Grounding protection NOTICE Damaging of load cells Undesirable electrical currents can arise during welding or lightning. To protect the load cells against such currents, bridge the load cells using highly flexible grounding cables. 6.2.2 Transverse forces and overload protection Overloading of load cells NOTICE Risk of overloading...
Page 34
Commissioning 6.2 Application planning Dimensioning for overload When step changes in load cannot be excluded during measuring, for example, due to application of a load in free fall, you must take appropriate precautions to avoid damage to the load cell, e.g. by using elastomer bearings or load cells dimensioned for higher rated loads. When dimensioning load cells, include a safety margin to guard against overloading: •...
Commissioning 6.2 Application planning 6.2.3 Lengthening and shortening the connecting cable Load cells can be equipped with connecting cables with four or six cores. Note Measurement errors Connecting cables are only permitted to be extended using electro-magnetically compatible housings, such as the SIWAREX JB junction box. Single load cells If a scale is equipped with a single load cell, the scale can be directly connected to the weighing module if space permits.
Page 36
For connecting the junction box to the weighing module, to extend a load cell connecting cable or for cross-connection of two junction boxes, a shielded, six-core cable must be used, e.g. Li2Y2x0.75St+2x(2x0.34St)-CY Siemens Order No.: 7MH4 702‑8AG or, for intrinsically safe Ex applications, 7MH4 702‑8AF.
Commissioning 6.3 Adjustment and initial commissioning Adjustment and initial commissioning WARNING Missing type of protection and loss of approval If the load cell is not operated with an intrinsically safe power supply, the type of protection - intrinsically safe is no longer guaranteed and the intrinsically safe approval may be revoked. Permanently erase, therefore, the irrelevant types of protection on the rating plate before commissioning, so that erroneous deployment can be avoided.
Commissioning 6.3 Adjustment and initial commissioning 6.3.2 Initial commissioning 1. Align the load cell site horizontally and level over the complete area. 2. Clean the load cell site and load cell base until both are absolutely clean. 3. Grease the contact surfaces of the force transfer elements with bearing grease. 4.
Commissioning 6.3 Adjustment and initial commissioning The corner load errors can be electrically compensated. This is done by matching the individual measured values to the smallest measured value by connecting additional resistors. For details of how to do this see section Example for corner load adjustment (Page 39) The resistors are connected in series with the load cell measuring signal.
Page 40
Commissioning 6.3 Adjustment and initial commissioning Procedure 1. Measure the output resistances R of the load cells LC. Alternatively: Use the values from the corresponding data sheet. Example: Load cells Example values LC 1: 1004.52 Ω LC 2: 1003.64 Ω LC 3: 1010.70 Ω...

Calculate the compensating resistance: Use the following formula: Determined compensation resistance, to be connected in the signal cable SIG+ Output resistance of the load cells; can also be measured under load Weight error: Differential value from the lowest weight value Test load;...
Service and maintenance Basic safety instructions Servicing and maintenance of the load cells The load cells are in general maintenance free. Regular inspection and checking of the mechanisms for force transfer, oscillation limitation, lifting and overloading will however improve their reliability. The inspections should also be performed after serious environmental events such as storms, floods or earthquakes.
Service and maintenance 7.4 Disposal Required forms • Delivery note • Return document (http://www.siemens.com/processinstrumentation/returngoodsnote) with the following information: – Product (item description) – Number of returned devices/replacement parts – Reason for returning the item(s) • Decontamination declaration (http://www.siemens.com/sc/declarationofdecontamination) With this declaration you warrant "that the device/replacement part has been carefully cleaned and is free of residues.
Error messages and troubleshooting Repair Note Unnecessary costs for repairs Please only return faulty load cells to our repair center accompanied by an accurate description of the fault. This simplifies the diagnostics. Error messages Rated load exceeded If load cells are loaded beyond their rated load, this can result in an error message in the weighing module.
Error messages and troubleshooting 8.4 Checking the load cells Checking the load cells NOTICE Damaging of load cells Do not use an Ohmmeter to measure resistances that feeds a higher voltage into the load cell than is permitted in the specifications. Locate and check faulty load cells 1.
Error messages and troubleshooting 8.5 Measures in the event of overloaded load cells Measure the input and output resistance 1. Disconnect the load cell. 2. Measure the input voltage between EXC+ and EXC-. 3. Measure the output voltage between SIG+ and SIG-. The resistances must correspond to the values specified in the data sheet or in the specifications.
