This measuring range corresponds to the transmission range of the poten-
tiometer which is given by the customer. The output of the instrument
transformer should be wired against GND with a resistor 2 to 10 kΩ to ena-
ble the initial value of 0 V to be set. However, the output load should be
dimensioned so that an output current of 15 mA won't be exceeded in the
end position (10 V).

Trim potentiometer Pe is used to adjust a voltage of 10 V to potentio-
meter values of 60 to 100 % of the total range.
Alignment of the instrument transformer (MWU)
1. Move axis to final position.
2. Turn potentiometer (Pe) until an output voltage of (10 V) is measured.
5.6 Magnetic absolute encoder (Profibus-DP; CANopen; serial
interfaces)
After correct mounting and wiring, the actuator can be activated by tur-
ning on the 24 V power supply. Green lighting of the two LED's signals that
no limit switches are active (see
). Now, the standard protocol ena-
bles customized parameterization of the actuator via the serial RS232 or
RS485 interface.
