Danger to life due to electric voltage!

Immediate danger to life when touching live parts.

Switch off the machine before replacing the SE-board!

DANGER

7.5.3

Tests

Tests are used to check the communication between the LZE-V, the SE and
the sensing heads as well as the communication of the interface connections
between the SE and the machine section electronics.

When starting the test, each rotor of the chosen rotor range will go into a
forced lock one by one starting with the smallest rotor number.

At the same time, the rotor position will also switch to red if the interface
cable between the SE and the machine section electronic is connected the
right way.

7.6 Replacement of Sensing Head and SE-Board

Replacement of the sensing head and its cables is possible while the machine
is running. Just unplug the cables.
