To obtain the proper signal, the sensor selection jumper must be set on the correct position
dependent on type of Current Sensor used:
1. If the control is connected with a Primary Current Transformer, the sensor selection
jumper should be put on the two pins on the right, as shown in Figure 8-1.
2. If the control is connected with a Secondary Rogowski Coil, the sensor selection jumper
should be put on the two pins on the left, as shown in Figure 8-2.
This hardware setup must be done when the control is initially installed, when a new different
type of Current Sensor is connected with the control or control board is exchanged.

These working modes are used to inform the control which Current Sensor has been connected
and which current setting will be used to input data. The control will then automatically adjust
the gain of the embedded amplifier and control the working current at the desired value.
Before CONSTANT CURRENT function is operational, the operator must inform the control
which working mode is selected by setting the proper EXTENDED FUNCTION parameters
