    Assembly Assembling the torque limiter comprises the following steps: • Preparatory work (Page 21) • Assembling the torque limiter (Page 21) • Adjusting the torque (Page 22) WARNING Danger due to bursting of the torque limiter If you do not observe the information stipulated here regarding assembly, this can lead to the torque limiter bursting during operation.

  • Page 22: Adjusting The Torque

    Assembly 5.3 Adjusting the torque 6. Remove all parts one at a time up to and including the first friction lining (4, 6, 7, 8, 9, 10, 11). 7. Push the slip module (12) onto the race (5). 8. Reassemble all the previously removed parts (4, 6, 7, 8, 9, 10, 11) in their original order. Ensure that the cup springs are correctly aligned.

    Assembly 5.3 Adjusting the torque 6. Tighten the adjusting screws (10) according to the required torque limit from table Ad- justment tables for the limiting torque (Page 24). 7. Count every 1/6 turns as you do so. 8. Proceed one step at a time so that each screw is tightened no more than 4/6 turns at a time.

  • Page 27: Commissioning

    Commissioning In order to ensure safe commissioning, carry out various tests prior to commissioning. Testing before commissioning DANGER Danger Overload conditions can occur during the commissioning of the torque limiter. The torque limiter can burst and metal parts can be flung out. There is a risk of fatal injury from flying fragments.

  • Page 29: Operation

    Operation SECUREX torque limiters are components that absorb individual load peaks. This is how the torque limiters protect the system. Prevent continuous slippage, especially at high relative speeds. This leads to premature wear of the friction linings. NOTICE Prevent slippage from occurring with a duration of > 1 second so that the friction linings do not heat up excessively.

  • Page 30: Identifying The Fault Cause

    Operation 7.2 Faults - causes and rectification 7.2.2 Identifying the fault cause 7.2 Faults - causes and rectification Faults occur frequently due to application errors or they occur due to operational circum- stances such as wear of wearing parts or changes to the system. The faults and fault causes listed below only serve as an indication for troubleshooting.

  • Page 31: Possible Causes

    Operation 7.2 Faults - causes and rectification Fault Cause Rectification Sudden changes in the noise level and/ Incorrect maintenance of the torque lim- Please observe all the stipulations and or sudden occurrences of shocks iter. requirements given in chapter Servi- cing.

  • Page 32: Maintenance-Related Causes

    7.2 Faults - causes and rectification • Stipulated maintenance intervals not adhered to. • Replacement parts that were used were not original replacement parts from Flender. • Flender replacement parts that were used were old or damaged. • Leak in the area of the torque limiter not detected so that chemically aggressive sub- stances damage the torque limiter.

  • Page 33: Maintenance

    Maintenance Maintenance intervals 8.1 Maintenance intervals WARNING Danger due to torque limiter heating up If you do not observe the maintenance intervals stipulated here, this can lead to the torque limiter slipping continuously during operation. The friction energy that then occurs can cause the torque limiter to heat up.

  • Page 34: Maximum Permissible Wear

    Maintenance 8.2 Maximum permissible wear Maximum permissible wear 8.2 Maximum permissible wear Measure the friction lining strength. Check if there is still 50% of the original strength left. If this is not the case, replace the friction linings as described in section Replacing wearing parts (Page 34).
