300/316 Bosch Rexroth AG | Tightening Technology 10 Working with the System10.4 Results storage and statisticsFigure 10–62: Results index card with open Options fieldIf Delete all filters is selected, all filters that have a checkmark next to them in the column selection willbe reset to the standard value (see “Results index card” on page 301 for additional filter settings).The additional information necessary to store tightening results in the Q-DAS ASCII transfer format is enteredin the Q-DAS field names group field.UpdateIf this button has been selected (Fig. 10–62 on page 300) the most recent result will always be read outof the results storage and inserted in the results in the BS350.NoteBS350 collects the results in the working memory. Results that are overwritten in the controller’s ringmemory also remain there.Load all resultsCharacteristics withintervention limitsIf this button has been selected (Fig. 10–62 on page 300) all of the data located in the results storagewill be read out and displayed. The time needed for the data transfer is dependent on the data quantity,as well as the selected connection between the tightening cell and the BS350 (Ethernet or USB).Intervention limits are used to signal deviations of the set value towards the upper or lower monitoring limitearly on. At this point, the user should already intervene to correct the tightening sequence. In accordancewith this, in the Lower: and Upper: fields, the respective intervention limits for the characteristic must beentered. The intervention limits must be lower than the monitoring limits, as the tightening case is evaluatedas NOK when the monitoring limit is reached and even cancelled. Further information on the monitoringfunctions and limits can be found in chapter “Tightening Processes” from page 201.Monitoring limits may not be used as intervention limits, as the tightening is already faulty at this point.This should be avoided. Suitable intervention limits are at:– 95% of the upper monitoring limit (upper intervention limit)– 105% of the lower monitoring limit (lower intervention limit, see example below).However, intervention limits do not have to be stipulated.In the list fields 1: and 2: (Fig. 10–62 on page 300) the characteristic whose data should be statisticallyevaluated is selected in each field. Identical characteristics in 1: and 2: are not permitted. The followingcharacteristics may be selected, depending on the configuration of the results storage (see page 295):– Torque– Angle– Gradient– All monitoring functions.System 350 | 3 608 878 040/05.2008
