7.4 Installing the slotted disc (rotational speed measuring
system only)
To prevent damage to the rotational speed measuring system’s slotted disc
during transportation, it is not mounted on the rotor. The customer must attach
it to the mounting ring before installing the rotor in the shaft train. The
mounting ring and the associated rotational speed sensor are already
mounted at the factory.
The requisite screws, a suitable screwdriver and the threadlocker are included
among the components supplied.
