If after the ACCEPTANCE TESTS the relay is held in storage before shipment to the job site, it is reconnended that the vi sua1 and mechani ca1 inspection described under the section on ACCEPTANCE TESTS be repeated before installation.
Check that the adjustable cam lobes are set in the proper positions to provide breaker reclosing impulses at the desired times. The fixed lobe in the zero (0) position will provide an irrmediate reclosing impulse when the NLR relay is in the RESET position and the breaker trips. A second lobe in position 3 wi 11 provide a second rec]osing impulse 3 times the step-time interval (or 15 seconds) after the first breaker trip when the NLR is set for the standard step time. Likewise, a third lobe in position 9 will provide a reclosing impulse 9 x 5 (or step time) or
45 seconds after the first breaker trip. The final lobe in position 21 wi 11
provide a reclosing impulse 105 seconds after the first breaker trip.
Set the Reset Link in the position that will provide the desired time delay before rapid reset.
