FOR OTHER OPERATIONAL ASPECTS

Abnormal operation | Temperature rise | Controls Abnormal operation In order to find out how well a JMG machine would stand the risk of fire or mechanical damage, the motor of each brand was stalled by locking its moving parts. Safety devices like OLP, fuses, thermal cutouts, or any other motor-protection device must operate and the temperature of the windings should not go beyond the specified limit.

During the tests, appliances shall not emit flames or molten metal; enclosures shall not deform to such an extent as would impair compliance with this specification. After the tests, the appliance shall withstand electric strength test.
