The running time can be pre-selected with the lid open or closed.
To activate the setting of the running time press the key „time“ (6).
In the display „time“ (A-3) flashes the indication „m : s“ or „h : m“, depending on the previous
setting.
To set the desired value use the adjusting knob (1). After exceeding of 59 min 50 sec the indication
changes automatically into „h : m“. After exceeding of 99 hours 59 min the word „cont” appears in
the display „time” (A-3). That continuous run can only be interrupted by pressing the key „stop” (10).

2.3.3 Preselection of brake intensity and acceleration
Through the key „accel/decel“ (5) this function is activated.
By pressing the key once the word „accel“ (M7) flashes in the display „accel/decel“ (A-2). The
desired acceleration can be pre-selected by the adjusting knob (1). The value 0 is equivalent to the
lowest and the value 9 to the highest acceleration.
By pressing the key „accel/decel“ (5) twice, in the display „accel/decel“ (A-2) indicates the word
„decel“ (M8). Now the desired brake intensity can be pre-selected by the adjusting knob (1). The
value 9 is equivalent to the shortest and the value 0 to longest possible brake time.
All with number marked passages refer to figure 19
See „table 4: acceleration and deceleration times“ (APPENDIX P. VIII). There are shown the
acceleration and deceleration times for the acceleration and deceleration stages 0 to 9 for
permissible rotors.
