M10 tie rods 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.
Furthermore, before assembling, check that the conical coupling seats (on the alternator and motor) are regular and well
cleaned. If a threaded reduction bush is provided, it must be screwed onto the crankshaft before proceeding with steps 1-2-3-4.
B2 CONSTRUCTION STRUCTURE (SAE flange with elastic disks)
This manufacture shape foresees the direct coupling between the first motor and the alternator. It is advisable to proceed with
the assembly as follows:
1) Check the correct positioning of the rotor with the help of the table shown in Figure 3A for PHASE 9 ES-EM and Figure 6A
for PHASE 9 SM-PS-PM
2) Remove any rotor locking devices located on the coupling side.
3) Approach the alternator to the prime mover as shown in Figure 3B for PHASE 9 ES-EM and Figure 6B for PHASE 9 SM-PS-
PM
4) Center and secure the stator to the flange of the first motor with the appropriate screws as shown in Figure 3C for PHASE
9 ES-EM and Figure 6C for PHASE 9 SM-PS-PM
5) Center and secure the rotor joint to the flywheel of the prime mover with the appropriate screws, acting through the ap-
propriate openings, as shown in Figure 3D for PHASE 9 ES-EM and Figure 6D for PHASE 9 SM-PS-PM. Rotate the rotor as
shown in Figures 4A and 4B for PHASE 9 ES-EM and Figures 7A and 7B for PHASE 9 SM-PS-PM
FINAL CHECKS
At the end of all the described coupling operations it is necessary to check the correct axial positioning; it must be verified that
the end of non-drive end side bearing has an expansion space of 3 mm.
Do not lift the group of assembled alternator-motor from the eye bolt of the alternator, this one should
be used only and exclusively to lift the alternator (Figure 8).
4. START UP PROCEDURES
⇒ Before starting the machine, it is necessary to check that all the terminals of the terminal blocks are tightened regularly
and that there is no impediment to the rotation of the rotor. If the alternator has not been used for a long time, before
putting it back into service, check the insulation resistance to ground of the windings, bearing in mind that each part to
be checked must be isolated from the others.
Before checking the insulation resistance to ground of the windings with a megger or other high voltage
devices, completely disconnect the electronic regulator from the alternator; the high voltages of the devi-
ce can damage the components of the regulator.
⇒ Normally, windings having resistance to earth ≥1 MΩ - 500V are considered sufficiently insulated. If windings resistance
is lower, 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 neces-
sary to verify that the alternator/welder'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. Power cables connections should be
carried out by qualified personnel when the machine is completely stopped and disconnected from the
load.
Nameplate values: These alternators are designed to supply only the voltage and frequency specified in the rating plate.
The PHASE 9 series can be used both with an external BMS (Battery Management System) for managing the
battery charging process or with a constant voltage system.
4.1 CONSTANT VOLTAGE SYSTEM
To supply a constant voltage without the external control of a BMS, PHASE 9 alternator must be equipped with the HVR11-CV
regulator.
With this configuration, the machine will supply a constant voltage both in no-load and with load and the charging current
will depend on the state of charge of the batteries. For the protection and duration of the batteries, the supplied current must
be limited in value and in time. If the system is not equipped with an external control device, it is necessary to use the current
limiter (CL) available on request.
Start-up procedures for PHASE 9 with constant voltage system:
4.1.1 Start the unit up to the nominal speed shown on the alternator data plate. In this case, the reference voltage of the
electronic regulator is factory-set and corresponds to the output voltage on the terminals of the machine. The reference voltage
can be modified by acting on the VG trimmer of the electronic regulator.
4.1.2 At rated speed, the machine can supply up to the maximum current shown on the data plate, and the output voltage will
remain constant regardless of the applied load.
N.B. In a constant voltage system, it must be considered that the current value must be limited in time to pre-
serve the useful life of the battery.
4.2 SYSTEM WITH EXTERNAL CONTROL (BMS).
For optimal battery charge management, the system can be integrated with an external battery management control com-
monly known as Battery Management System (BMS). In this configuration, the PHASE 9 is equipped with the HVR11-BMS
electronic regulator that allows the alternator to communicate with the BMS.
The machine can be controlled by the BMS on which it is possible to set the parameters necessary for managing the most
suitable charging process for each type of battery.
The electronic regulator has a reference voltage of 0 - 5 Vdc where 0 corresponds to the maximum and 5 to the minimum
output of PHASE 9.
Start-up procedures for PHASE 9 with external BMS control:
4.2.1 Start the unit up to the nominal speed shown on the generator plate. The BMS control output is connected to the M6-M8
terminals of the electronic regulator; make sure that the BMS is supplying either a voltage of 5VDC that corresponds to the
minimum supply value of the machine or that it does not supply any voltage. Pay attention to the polarity: M6(-) and M8(+).
4.2.2 At this point, the set is working and the PHASE 9 at the minimum supply level is controlled by the BMS, therefore, the
voltage on the M6-M8 regulator terminals will be proportional to the Current/Voltage variables that the BMS must control in
the different battery charging stages.
5. VOLTAGE CALIBRATION
Voltage calibration. The calibration of voltage should be carried out by qualified personnel only because
of electrocution hazard
Output voltage regulation should be carried out at nominal revolving speed. The alternators are calibrated to deliver the no-
minal voltage. To correct the output voltage of the alternator it is necessary to act on the VG potentiometer on the regulator.
Voltage increases with a clockwise rotation of the potentiometer.
Protections
The electronic regulator acts also as protection against overloads on exciting windings of the alternator when functioning at
a speed lower than the nominal one or in case of overload. A first protection (Hz) checks the frequency of the output voltage
and de-excites the alternator when it is lower than 10% of the rated value. A second protection (OL) checks the voltage at the
ends of the exciter stator and de-excites the alternator when this voltage is higher than the intervention level set with the OL
potentiometer. The intervention level can be increased with a clockwise rotation of the potentiometer.
