Assembling Instructions - Linz electric SPE-E1E Serie Instrucciones Para El Uso Y El Mantenimiento

⇒ Normally, windings having resistance to earth ≥1 MW are considered sufficiently insulated.
If windings resistance is lower than 1 W , insulation will have to be restored by drying the winding (using,
for example, an oven at 60°-80°C temperature, or by making circulate through the wiring a proper value
of current obtained from an auxiliary source). It is also necessary to verify that the alternator's metallic
parts, and the mass of the entire set are connected to the earth circuit and that the latter satisfies any
applicable legal requirements.
Mistakes or oversights concerning earthing may have fatal effects.

3. ASSEMBLING INSTRUCTIONS

Assembling should be carried out by qualified personnel after reading the manual.
B3/B14 Construction Form (E1E)
The construction form B3/B14 requires the use of a flexible coupling between the drive motor and the
alternator.
The flexible coupling should not originate any axial or radial forces during operation, and will have to be
mounted rigidly on the alternator shaft end. Please follow the instructions below while assembling:
1) Apply the flexible coupling and the adaptor on the alternator as shown in Figure 1A.
When positioning the flexible coupling, remember that once coupling is over the rotor has to expand
itself axially towards the coupling located on the non-driving end. To make this possible it is necessary
that after assembling the shaft end is positioned according to the cover pattern, as illustrated in Figure,
and related table, 1B.
2) Place the relevant flexible coupling on the revolving part of the diesel engine, as shown in Figure 1C.
3) Mount the coupling's rubber blocks.
4) Couple the alternator to the drive motor by screwing, with suitable screws, the adaptor to the motor
(see Figure D).
5) Fix, using appropriate rubber anti-vibration dampers, the motor-alternator unit to the common bed-
plate. Special attention must be paid not to cause any stretching that may affect the natural alignment
of the two machines.
6) Make sure that the alternator's non-driving end bearing has the recommended expansion allowance
(min. 2 mm.) and that it is preloaded by a preload spring.
B3/B9 Construction Form
This type of mounting arrangement allows direct coupling of alternator and drive engine. Please follow the
instructions below when assembling:
1) Secure the cover "C" to the first mover as shown in Figure 2A.
2) Secure the alternator to its cover with the 4 bolts provided as shown in Figure 2B.
3) Apply the tie rod "13" for the axial securing of the rotor, inserting the washer "50", screwing the self-locking
nut "51" and pulling out the tie rod about 2mm, as shown in Figure 2C.
4) Axially lock the rotor by tightening the tie rod with a torque wrench (tightening torque of 21 Nm for M8 tie
rods, 48 Nm for M10 and 120 Nm for M14 tie rods) as shown in Figure 2D.
Check that the self-locking nut "51" has a threaded portion of the tie rod that enters the rotor
thus allowing a secure locking. Before assembly, check that the coupling conical seats (on the
alternator and engine) are regular and clean.
In the case where there is a threaded reduction sleeve, it must be screwed onto the engine shaft first and then
proceed as shown in sections 1-2-3-4.
B2 Construction Form (E1E11-E1E13).
This construction form too allows direct coupling of alternator and drive motor. Please follow the instructions
below when assembling:
1) Check that the rotor is positioned correctly, as illustrated in Figure 3A.
2) Remove rotor's locking components on the non-driving end.
3) Place the alternator next to the drive motor, as illustrated in Figure 3B
4) Centre and secure the stator to the drive motor's flange, using suitable screws, as shown in Figure 3C.
5) Centre and secure, using appropriate screws, the coupling to the drive motor's flywheel working through
the air outlet, as indicated in Figure 3D.
Turn the rotor as shown in Fig. 4A and 4B
FINAL CONTROLS To the term of all the overwrite couplings it is necessary to control the correct
axial positioning; it must be verified that:
1) Between the end of non-drive end side bearing and the surface of axial clamping exists a
space of:
2 mm for the alternators SPE-E1E10
3 mm for the alternators E1E11 ed E1E13
2) The brushes are centred on rings of the collector.
4. USAGE
Power cables connections should be carried out by qualified personnel when the machine
is completely still and the power cable is disconnected.
Voltage and output frequency
These alternators are designed to supply only the voltage and frequency specified in the rating plate.
