Start sequence
To enable the machine at start-up on stepping operation 2 different start
sequences can be chosen:
1.) The required number of interruptions of the LC must be completed
and then the start button must be pressed.
2.) The start button is pressed first, and after that the required number
of interruptions must be completed.
The request to start the operation (e.g. 2 steps according to the diagrams
below) is signalled by a flashing lamp (terminal 48). The request to press
the start button is signalled by continuous light on a lamp (terminal 58).
After finishing the starting sequence correctly the lamps go off and the
contact K1 and K2 close.
