Overcurrent Relay K114 Controls and Instruments (Continued) Figure 2-5, 3 Current Pickup Tap for phase C Provides for seven pickup settings which 4 are marked In CT secondary amperes. When a pin is pulled out, that phase switches to the maximum tap setting The pin may be moved with the relay. In service. Figure 2-5, 4 TRIP test pushbutton for INST This pushbutton, recessed to prevent function accidental operations, will produce a trip signal and operate the INST target (6, below). Figure 2-5, 5 INST dial Used to select instantaneous pickup set- 3 tings. The markings around the dial Indi- cate multiples of pickup tap setting For example, if the phase A tap is set to 6 amperes and the INST dial is set at 8, the INST setting is 6 amperes x 8 = 48 amperes and an instantaneous trip will occur at 48 amperes in phase A of the relay.
