To test relay K102, connectrelay as shown in test setup figure 5-7.(a)Connect a variable 0 to 160VAC source and variablefrequency (50 to 60 Hz) sourceto! terminals 1 and 2 with switchS1 in series.(b)Connect lamps DS1 and DS2,switch S2, and a 24V DC supplyas shown in figure 5-7.(c)Close S1 and S2. Set voltageto 120 volts on terminals 1 and2 and vary the frequency from50 to 60 Hz. DS1 shall stay litand DS2 shall remainextinguished.(d)Slowly increase the voltage to140 volts. Vary the frequencyfrom 50 to 60 Hz. DS1 shallstay lit and DS2 shall remainextinguished.(e)Slowly increase the voltage to154 volts. Vary the frequencyfrom 50 to 60 Hz. DS1 shallstay lit and DS2 shall remainextinguished.(f)After each light transfer,remove AC power to clear theFigure 5-5. Transformer T103, Schematic5-8
