Step 4

: Power up the unit and press the [Off] button. In

this state, the motor should not rotate. Press [Off] to stop
the motor at any time. Note that the LED on the [OFF] but-
ton should be lit. If alarms or warnings are flashing, please
see chapter 7 for more information.

Figure 4.46:

Step 5

: By pressing the [Hand on] button, the LED above

the button should be lit and the motor may rotate.

Figure 4.47:

Step 6:

 The speed of the motor can be seen in the LCP. It

can be adjusted by pushing the up
