Roll 1: StandardRoll (load cells A and B), SingleSideA or SingleSideB (load cell A or B)
Roll 2: StandardRoll (load cells C and D), SingleSideC or SingleSideD (load cell C or D)
When single side measurement is selected the measured signal is multiplied by two and
presented as web tension on display and analog output.Setting Object Types for Segmented Roll
Object type SegmentedRoll can be used for up to 12 load cells that are connected to one, two or
three Tension Electronics PFEA113.
Each PFEA113 must be set up for:
? one input (load cell connected to A)
? two inputs (load cells connected to A and B)
? three inputs (load cells connected to A, B and C) or
? four inputs (load cells connected to A, B, C and D)Segmented Roll Scale Factor (SRSF) is used to compensate the total measured tension and
present an estimate of total tension when not all rolls are supported by load cells in a segmented
roll application. For calculations of SRSF, refer to.Connecting Multiple Electronics (two or three PFEA113 connected together)
Analog inputs AI1 and AI2, see Figure 3-10, are used for connecting two or three PFEA113
electronics together. The configuration example below is based on Figure 3-10.
If N/m, kN/m, kg/m or pli is chosen as presentation unit, the total web width must be entered in
all three electronics.
The same wrap gain value must be entered in all three electronics.
If the scale factor SRSF is used, the SRSF must be calculated and set separately for each
electronic unit, see also Appendix A.3 Technical Data for Tension Electronics PFEA113.
1. Configuration rules for analog outputs(AO) on PFEA113 (1) and PFEA113 (2) to be
connected to AI1 and AI2 on PFEA113 (3):
– Choose voltage output, since AI1 and AI2 can only be connected to voltage signals.
– Use the ConnectSignals alternative that includes the load cell signals you want to connect to the output, see Section 3.12.7.
– Set the filter settings to 5 ms (the shortest selectable time).
– Set HighTension (N, kN, kg, lbs, N/m, kN/m, kg/m or pli) and HighOutput (V).
