In this mode, the sequence order is calculated from the actual run time of each load. The load with the least run time hours will be the first in the sequence order. The load with the highest run time hours will be the last in the sequence order. The actual run time values are displayed by the parameters RUNT-01...RUNT-12.
The moment of recalculating the new sequence order is defined by parameter CYC-02 (type of runtime rotation)
Table 5. Type of changeover selection
CYC-02 |
Type of runtime rotation |
0 |
Recalculate the new sequence order at a predefined day/ time (defined by parameter CYC-03, CYC-04 and CYC-05) |
1 |
Recalculate the new sequence order at a predefined day/time (defined by parameter CYC-03, CYC-04 and CYC-05, see table 6.) and the difference in runtimes exceeds the value of CYC-06. CYC-01 has to be set to 3 - runtime rotation. |
2 |
Recalculate the new sequence order when the difference in runtimes exceeds the value of CYC-06 |

* The week day can be selected with CYC-04. The start of the week depends on the used controller hardware.
The example (Fig. 7) shows 3 loads that will be rotated based on the actual run time values. The result after recalculation is shown in Fig. 8.
