Figure 3-10. Three PFEA113 Connected to Segmented Roll with 12 (max.) Load Cells
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).
2. Configuration rules for the AI1 and AI2 on PFEA113 (3)
–Set HighTension (N, kN, kg, lbs, N/m, kN/m, kg/m or pli) of AI1 = HighTension of
PFEA113 (1).
–Set HighInput (V) of AI1 = HighOutput (V) of PFEA113 (1).
–Set HighTension (N, kN, kg, lbs, N/m, kN/m, kg/m or pli) of AI2 = HighTension of
PFEA113 (2).
–Set HighInput (V) of AI2 = HighOutput (V) of PFEA113 (2).
3. Configuration rules for the output (used for summation) on PFEA113 (3)
– Choose voltage output or current output.
–Use the ConnectSignals alternative that includes all signals you want to connect to
the summation output, see Section 3.12.7.
– Set the desired filter settings.
Note! If the Step Response time is set to 5 ms and analog inputs (AI1 and/or AI2) are
included in the summation output the filter settings will increase to 6 ms.
