6. Generator Testing
i
A limit switch is actuated when closing the protective cover
to guard the rotating parts for direct and V-belt drives of
generators.This ensures that a generator test can only be
carried out when the protective cover is closed.
i
Larger swivel-arm-mounted AC generators (28 V, 60 A) can,
in some cases, not be mounted for direct drive and should
therefore be mounted for belt drive (see section 6.1.3).
i
If the fan pulley of generator is too big, use for testing a
smaller normal fan pulley.

- Depending on the size of the generator, place a single or a
double clamping vee (4/7) in the centre of the height-adjustable
mounting table (4/6).
- Fit a coupling half with appropriate socket wrench (4/3) to the
drive pulley of the drive motor (4/2).
