B. TROUBLESHOOTING
All measurements other than the cord short circuit test are performed as
energized.
The relevant person shall wear insulating shoes and shall not contact
the circuits by hand. In case of contact, he shall cut off power, and re-
supply the required energy during measurement.
The faults in the product may be examined as follows: When the product is supplied with
power;
1. If no component is operating (motor, lamp, etc.)
> The product may not be receiving power. In such a case, check the power in the
circuit, too.
♦
Circuit power check;
> Fuse may be blown if there is no power in the circuit. Make sure that the fuse is on.
> Power cord may be damaged if the fuse is OK. In such a case, a cord short circuit
test shall be performed.
♦
Short Circuit Test for the Power Cord;
>
Switch may be faulty if there is power in the circuit. In such a case, a switch short
circuit test shall be performed.
♦
Short Circuit Test for the Switch Cord;
> The motor is faulty if there is no fault in the motor speed cords of the switch.
> There may be a fault in the receptacle cord if there is no fault in the lamp cord of the
switch.
♦ Short Circuit Test for the Receptacle Assembly
> The lamp is faulty if there is no fault in the receptacle cord.
2. Grounding cord may be damaged in case of electric shock when you contact the
product.
♦
Short Circuit Test for the Grounding Cord
3. If the circuit is 220V at the motor socket outlet but the motor is not running the
robustness of the windings can be checked by checking the motor windings.
