SITRANS SL - Exchange of the ATEX cables
Only qualified service technicians who are experienced with the requirements for Ex d and Ex e
and who are able to evaluate the result are allowed to exchange the ATEX cables!




Follow also the safety notes in the Operating Instruction A5E01132948-04
and in the Certificate PTB 08 ATEX 1008X

Required Tools:
Allen key 2.5mm, small screw driver, flat spanners with wrench sizes 22, 24, 27, 30 and 36mm

Dismounting of the existing cables

     ·    Switch off the SITRANS SL in the Ex zone and wait for 2 minutes
     ·    Switch off the sensor purging and dismount it from the sensor
     ·    Dismount the sensor connection cable between the junction boxes and transport the sensor heads to a clean
          area
     ·    There may be some white powder in the junction boxes: this is talcum powder and should be removed
     ·    The window flanges stay on the process and also the process purging stays switched on: the process keeps
          closed and the windows keep clean, also the alignment is not affected

In clean area:

     ·    Open the safety screws on the lids and open the sensor heads
     ·    Dismount carefully the transmitter and receiver loop cables and main connection cable from the NPT thread
          in the sensor housings and the junction boxes. In case of connection cable analog, the reducing adapter
          must not be removed.

     Note: Check that the NPT threads of the sensor housings are complete and undamaged

Mounting and Connection of the Receiver Connection Cable (PROFIBUS)

          According ATEX and FM standard at least 5 threads have to be screwed in.

  · Screw the ATEX cable gland of the Profibus Connection cable with 2 windings Teflon tape into the receiver
    housing as shown below


                        Wrap the wire ends with isolating tape to a strand to make it easier to insert the
                                   cable and to avoid to damage the isolation of the wires.

                       Release the two nuts (1) and (2) a bit to screw in the cable gland without turning
                                                     the complete cable.

                                   Screw the cable gland into the receiver housing with 5 threads.

                                              After mounting the cable gland tighten the nuts.
