A. The UCS Series relays do come with certain factory settings, however, these settings are not selected for any particular application. Each UCS sequencer undergoes a complete operational test at the factory before making its way to Kele's shelves. The "factory" trip points for the relays are actually the final settings used in the test procedure. If these settings fit your application, recalibration is not required.
