1. SAFETY PRECAUTIONS
Before using the generating set it is necessary to read the «Use and Maintenance Manual» for the generating
set and the alternato/welder and to follow the recommendations below:
⇒ A safe and efficient working can be achieved only if the machines are used correctly, in compliance
with the instructions provided by the relevant operational and maintenance handbooks and safety
regulations.
⇒ An electric shock can cause serious personal injuries and even death.
⇒ Do not remove the terminal board cover and the alternator's protection grid before the alternator has
come to a complete stop, and before deactivating the starting system of the generating set.
⇒ Only competent and qualified personnel should carry out the maintenance of the generating set.
⇒ Do not wear loose garments when working near the generating set.
⇒ All persons operating, handling or servicing the genset must always wear protective gloves and safety
footwear. In the event that the alternator, or the whole generating set needs to be lifted from ground,
the operators must also wear a safety helmet.
Safety notices used in this manual have the following meaning:
IMPORTANT! refers to dangerous or risky operations that may cause damage to the product.
CAUTION! refers to dangerous or risky operations that may damage the product or cause personal
injury.
WARNING! refers to dangerous or risky operations that may cause serious personal injury or even
death.
DANGER! refers to an immediate risk that may cause serious personal injury or death.
The person responsible for the installation of the generating set must make sure that all the
necessary safety arrangements are in place in order to make the whole plant compliant with
current local safety regulations (earthen, contact protection, explosion and fire safety measures,
emergency stop, etc....)
2. ALTERNATOR DESCRIPTION
The E1W13 DC welders/alternators are two or four-pole three-phase brushless machines with exciter. Either welder or alterna-
tor functions are governed by an electronic regulator.
They are manufactured in compliance with EN 60034-1, EN 60204-1, EN 55014-1, EN 55011 specifi cations, as well as with
the directives no 2006/42/CE, 2014/35/UE, 2014/30/UE.
Ventilation: Axial with air inlet from non-drive end side.
Protection: Standard IP 21. IP 23 on request.
Direction of rotation: Both directions are allowed.
Electrical features: Insulation components are made with class H material, for both stator and rotor. Windings are
tropicalized.
Power values: They refer to the following conditions: ambient temperature up to 40°C, altitude up to 1000 m. above
sea-level.
ENGLISH
OVERLOADS: A 10% overload for one every six hours is normally accepted.
Mechanical features: Casing and covers are made of aluminium alloy which holds out against vibrations. The shaft is
made of high-tensile steel.
The rotor is particularly sturdy to hold out against the runaway speed of the drive motors.
It is equipped with a damping cage which allows satisfactory operation even with single-phase, distorted loads. Bearings
have lifelong lubrication.
Operation in particular settings:
If the alternator is going to be used at more than 1000 m above sea-level, a 4% derating per each 500 m increase will
need to be operated. If ambient temperature exceeds 40°C a 4% derating per each 5°C increase will need to be operated.
INSTALLATION AND START UP
The following start up and control operations should be carried ou only by qualified personnel.
The alternator/welder must be installed in a well ventilated room. Ambient temperature should not exceed standard
⇒
recommended values.
Particular attention must be paid to ensure that air inlets and outlets are never obstructed. While installing the alternator
⇒
it is important to avoid direct suction of warm air coming from the alternator's outlet and/or from the prime motor.
Before starting up it is advisable to check (visually and manually) that rotation of the rotor is not blocked in any way. If
the alternator has not been used for a long time, before starting it up it is recommended to test the windings insulation
resistance to earth, keeping into account that every single part has to be insulated from the others.
As a first step disconnect the main rectifier and the connector of the electronic regulator.This particular checkup must be
⇒
carried out using a "Megger" instrument at 500 V. c.c..
⇒
Normally, windings having resistance to earth ≥1 MΩ at 500 c.c. 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 necessary 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.
3. ASSEMBLIG INSTRUCTIONS
Assembling should be carried out by qualified personnel after reading the manual.
B3/B14 CONSTRUCTION FORM
B3/B14 construction form requires the use of a flexible coupling joint between the drive motor and the alternator/welder.
The flexible coupling should not originate any axial or radial forces during operation, and need to be mounted rigidly on
the alternator shaft end. Please follow the instructions below while assembling:
We recommend assembly by following the following steps:
1) Apply the flexible coupling and the adaptor on the alternator/welder 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 bearing located
on the non-drive end side. To make this possible it is necessary that, after assembling, the shaft end is positioned
according to the cover, as illustrated in Figure 1B.
2) Place the flexible coupling on the revolving part of the engine, as shown in Figure 1C.
3) Mount the coupling's rubber blocks.
4) Couple the alternator/welder to the drive motor by screwing, with suitable screws, the adaptor to the motor (see Figure 1D).
5) Fix, using appropriate rubber anti-vibration dampers, the motor-alternator/welder unit to the common bed-plate.
