4) Position 1
Low compensation that allows natural free swing of
the arm while walking.
Position 2
Compensation increases progressively with flexion
of the arm and decreases automatically during
extension.
Position 3
Compensation remains constant. If set correctly,
the weight of the forearm is balanced by the com­
pensation and the forearm "floats".
Position 4
Low compensation until flexion stop.
► The upper arm rotation joint has bilateral stops (±
80 degrees) to block extreme movements. The fric­
tion of the humeral rotation feature at the upper arm
connection is easily adjusted by turning the external
adjustment screw.
1) The MyoRotronic cannot be combined with the
elbow joint. The MyoRotronic would be destroyed
when operating the elbow joint.
2) There are numbers for the plug contacts on the
plastic housing of the electric wrist rotator. These
numbers serve as orientation for connecting the
cables.
3) Attach the motor cable to one of the two contacts.
Connect two-pole receptacle to contact no. 3.
4) Connect three-pole receptacle to contact no. 2.
One of the three-pole connectors is marked with a
coloured dot.
5) If the two three-pole connectors are interchanged
when connecting them to the two contacts, no func­
tion of the System Electric Hand or System Electric
Greifer is possible.
