BE1-67 Functional Description 3-3Figure 3-2. Characteristic AngleTwo types of CHARACTERISTIC ANGLE controls are available and are specified by the style number. (Referto the option 3 column in Figure 1-9,Style Number Identification Chart.)1. A potentiometer provides continuous adjustment of the characteristic angle over the range of 0° to +90°.Options 3-1 and 3-3 have a control knob operated potentiometer. Options 3-5 and 3-6 have a screwdriveroperated, multi-turn potentiometer.2. A four position selector switch provides discrete settings of +300°, +45°, +60° and +75° (Options 3-2 and3-4.)When the phase relationship between the current(s) and voltage(s) do not meet the criteria of the directionalelement, an inhibit signal is output. This signal illuminates the appropriate PHASE INHIBIT LED on the relayfront panel and prevents the operation of the time overcurrent function in the relay. This signal also inhibitsthe operation of the optional directional instantaneous overcurrent element. The inhibit signals within the relayare provided for each sensed phase.Limited Region Of OperationThe directional element of the standard relay defines a region for which tripping is allowed. (This is shownas the gray area in Figure 3-2.) This region (angle $ as shown in Figure 3-3) may be reduced by the LIMITEDREGION of OPERATION control (a multi-turn potentiometer accessed through the front panel). The controlis continuously adjustable (with reference to I A in Figure 3-3) from ±5 degrees to ±90 degrees.
