  • Page 21: Installing

    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.

  • Page 22: Procedure For Mounting The Device

    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.

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 Operating Instructions, 07/2024, A5E02199611B-14...

  • 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: •...

  • Page 35: Lengthening And Shortening The Connecting Cable

    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.

  • Page 37: Adjustment And Initial Commissioning

    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.
