TM 9-6115-658-13&P 5-16REMOVALTag and disconnect leads (5, Figure 5-8). Remove four screws (4), lock washers (3), flat washers (2), and permissive paralleling relay (1). TEST1. Perform removal procedure above and position permissive paralleling relay (1) on work surface. Connect a variable AC voltage, 50-420 Hz, power oscillator across terminals 1 and 2. 2. Connect multimeter across terminals 5 and 6 and check for continuity. If continuity exists, leave multimeter connected for remainder of test. If no continuity exists, replace relay. 3. Connect a variable AC voltage, 50-420 Hz power oscillator, across terminals 1 and 2. 4. Apply 120 volts AC across terminals 3 and 4. 5. Adjust the oscillator output for 60 Hz. 6. Increase the oscillator output to a value of 20 volts. Multimeter should indicate no continuity. Slowly decrease the oscillator output until continuity is observed. Oscillator output voltage should be 8}1VAC. 7. Increase the oscillator output until multimeter shows no continuity. Oscillator voltage should be no more than 1 volt above previous voltage reading. 8. Perform steps 6 and 7 with multimeter connected across terminals 7 and 8. 9. Perform installation procedure using new relay if it fails to meet the requirements of steps 6 through 8. 10. If relay meets the requirements of steps 6. through 8., perform installation procedures. INSTALLATIONPosition permissive paralleling relay (1) in switch box and install flat washer (2), lock washer (3), and screw (4). Connect leads (5).
