6 Application of uL 60730-1 to Controls used to Provide Overtemperature Protection for Motors
6.1 With reference to 2.1,all performance testing required by the Standard for Automatic ElectricalControls - Part 1: General Requirements, uL 60730-1, on the control is to be pertormed with the controlconnected as intended to the motor.
6.2 Any test conducted on the control that does not result in an obvious inability of the motor to operateas intended,characterized by a cessation of rotation,shall not result in a temperature of the 'motorwindings in excess of the values specified in Table 32.1 of UL 1004-1.Cessation of rotation is consideredto be independent of an inability to start.
6.3 Any test conducted on the control that results in an obvious inability of the motor to operate asintended, characterized by a cessation of rotation, shall not result in a temperature of the motor windingsin excess of the values specified in Table 8.1 of UL 1004-3.Cessation of rotation is considered to beindependent of an inability to start.
Exception: Any test conducted on the control used within a motor intended for field installation shall notresult in a temperature of the motor windings in excess of the values specified in Table 32.1 of UL 1004-1.
6.4 Any abnormal test conducted on the electronic protection circuit that terminates as a result of acomponent failure,that failure mode shall be evaluated in a manner consistent with the requirements ofuL 60730-1 to ensure that the result is reliable and consistent.
6.5 Controls evaluated to provide required motor overtemperature protection shall provide the followingrequired safety functions when evaluated to the requirements of UL 60730-1.
