 Basic unit is started and runs through the startup phase. Then, the unit runs
through the respective program phases in accordance with the program sequence
and the numbers appear blinking
 The unit proceeds to the end of the prepurge phase (P30), goes to the start load
position and then displays P0 (ignition load sped). In the process, the display
shows alternately P0 (blinking) and the speed
 By pressing
A
(display changes to 0A and the speed appears blinking) and
pressing
or the speed can be changed in step sizes of 10 rpm within the
limits predefined by the OEM (P0max, P0min)
