6.2.2 Programme 2: AutoControl - LowInput
Proportional control with 2 electrodes or a switch.
The speed is increased proportionally depending on how fast the opening signal on the electrode
rises. When a switch is used, opening is at a constant speed. Closing is at the maximum speed of
200 mm/s. The gripping force increases proportionally to the time. The longer the signal on the
"CLOSE" electrode is applied, the higher the gripping force.

6.2.3 Programme 3: VarioControl
Proportional control with 1 electrode or 1 linear control element.
The terminal device is opened or closed depending on how fast and with what intensity the signal
rises or falls. By dropping the signal very slowly (very slow muscle relaxation), the terminal device
stops in the open position.
Control with one electrode: for patients with one strong electrode signal or co-contraction
•
Control with one linear control element: for patients with an electrode signal that is too
•
weak, or no electrode signal

6.2.4 Programme 4: VarioDual
Proportional control with 2 electrodes for patients with two strong electrode signals.
The terminal device is opened or closed depending on how fast and with what intensity the signal
on the first electrode rises or falls. The gripping force is determined by the subsequent or simul­
taneous electrode signal on the second electrode.

6.2.5 Programme 5: Digital Control
Proportional control with 2 electrodes or a switch.
The terminal device opens and closes at the fastest speed. The gripping force increases propor­
tionally to the duration of gripping.
2 electrodes or switch, proportional
Constant speed with application of the signal on the "CLOSE"
electrode or activation of the switch
Proportional to the signal strength on the "OPEN" electrode
Constant speed with activation of the switch
Proportional to the signal duration on the "CLOSE" electrode
For patients with two weak electrode signals
1 electrode or linear control element, proportional
Proportional to the increase in the strength and speed of the signal
Proportional to the decrease in the strength and speed of the sig­

Proportional to the decrease in the strength and speed of the sig­

2 electrodes, proportional
Proportional to the decrease in the strength and speed of the sig­

Proportional to the increase in the strength and speed of the signal
on electrode 1.
Proportional to the signal strength on electrode 2.
