Feedback Output Test
The feedback signal is automatically obtained in the positioner calibration process. It is
possible to measure this signal to check possible differences between the control and
feedback signals before putting the positioner into operation.
To test the signal, connect a 4 to 20 mA current generator to terminals 1 (+) and 3
(-). Connect a 24 Vdc voltage source in series with a multimeter on the current scale at
terminals 4 (+) and 5 ( - ).
Figure 8-35 Feedback Test Link
Set the current generator to 4 mA and gradually increase by checking the output signal
(feedback) on the multimeter. See the graph below for 4 to 20 mA current values.
The output signal must be the same as the current generator, if there is a difference,
perform the TRIM adjustment procedure indicated in the previous item.
