There are 2 possible methods for restoring
the above minimum values.
a) Dry out the machine for 24 hours in a
drying oven at a temperature of 110 °C
(without the regulator).
b) Blow hot air into the air intake, having
made sure that the machine is rotating with
the exciter field disconnected.
Note :
Prolonged standstill: In order to avoid
these problems, we recommend the use of
space heaters, as well as turning over the
machine from time to time. Space heaters
are only really effective if they are working
continuously while the machine is stopped.
Ensure that the alternator has the
degree of protection matching the
defined environmental conditions
.
3.2.2 - Mechanical checks
Before starting the machine for the first time,
check that:
- all fixing bolts and screws are tight.
- the cooling air is drawn in freely.
- the protective grilles and housing are cor-
rectly in place.

In case of reconnection, ensure that AVR voltage detection is correct !
Winding 9 : R 450 voltage det transformer (See specific diagram AREP or SHUNT)
The factory can supply a set of flexible shunts and special connection links as an option for making these connections. (*).
- the standard direction of rotation is clock-
wise as seen from the shaft end (phase
rotation in order 1 - 2 - 3).
For anti-clockwise rotation, swap 2 and 3.
- the winding connection corresponds to the
site operating voltage (see section 3.3).
3.3 - Terminal connection diagrams
To modify the connection, change the
position of the stator cables on the terminals.
The winding code is specified on the
nameplate.
3.3.1 - Terminal connection: 12 wire
The connection accessories are detailed in
section 5.3.3.
Any intervention on the alternator
terminals during reconnection or checks
should be performed with the machine
stopped.
