1) Application:
The equipment was developed for testing alternators and dynamos, in the same conditions in a vehicle.
2) Connection to the power grid - Single phase Motor:
The bench test BT200 has a single phase motor that can run on 127V or 220 V, considering default setting 220V. If the supply
voltage is equal to 127V, it's necessary changed the configuration of the motor wires. The following wiring diagrams for each
configuration:
Factory setting (220V): The wires T1 (blue) and T5 (black) are connected in phase (L1), T4 wire
(yellow) is connected to the neutral (L2) and the wires T2 (white), T3 (orange) and T8 (red) are
interconnected and must subsequently be isolated.
127V setting: wires T1 (blue), T3 (orange) and T5 (black) should be connected in the phase (L1)
and the wires T2 (white), T4 (yellow) and T8 (red) should be connected in the neutral (L2).
Notes:
• Provide a direct line, exclusive and independent through the lectrical panelboard to supply the
power to the equipment.
• It is recommended that the change in voltage must be made by a qualified professional.
WARNING!
The equipment must be connected to electrical panelboard across circuit breaker 50A, to supply 127V, or 30A to supply voltage
220V. Use wire with a minimum thickness of 4 mm² if the supply voltage is 127V. If the supply voltage is 220V, use wire with a
minimum thickness of 2,5 mm².
3) Installing the batteries:
Batteries not included with the bench BT200 must be acquired separately. During the installation process should be taken proper
care, as specified by the battery manufacturer.
If the bench is used for testing only at 14V should only install a battery and insulate the cables which will be disconnected. If the
bench is used for testing in 14V ou 28V will be necessary to install two batteries connected in series.

5) Operation:
To perform tests with agility and safety, you must follow the following procedure:
a) Position on the alternator bracket and secure it by adjusting the vertical axis.
b) The pulley of the alternator and electric motor must be perfectly aligned, to avoid problems of mechanical vibration, damage or
heating belt. The pulley alignment is made by moving the clamp in the direction indicated by the arrow.
c) Put the belt on the pulley of the electric motor and in the alternator pulley. Rotate the horizontal axis to tension the belt.
Note: recommended the use of belts size from A37 to A39.
d) Select which system will be used for the test: to test the 12V, jumper must be in position "12V - Bat". If the test is in the 24V,
jumper must be in position "Bat - 24V";
e) Connect the cable from the bench B + (red) on the terminal of the alternator B +;
f) Connect the cable from the bench-B (black) on the terminal Balternator;
g) Connect the cable from the terminal D + of the bench on terminal D + of the alternator;
h) Connect the battery switch. At this point the pilot lamp should light and the Voltmeter will
indicate the voltage of the battery;
i) Turn the engine switch from the bench. The alternator will come into operation and the indicator
lamp will turn off;
j) To apply the consumption of electrical current should low slowly the lever to control resistive
load.
Jumper / Battery Switch
WARNING!
The consumption test load should be done within the limits set to avoid overheating problems of resistive load. See the information
on the label located on the panel of the bench.
If during testing the alternator is overflow issues, you should turn it off immediately to prevent damage to the batteries and the
electrical system of the bench.
