Audio Indication
The SEL-8310 is equipped with a piezospeaker that produces four distinct audible
tones to supplement LED indications. The tones are denoted as pitches P1, P2, P3, and
P4 in this manual and are annunciated for either a short (50 ms) or long (150 ms)
duration. The tones or sequence of tones are depicted in Figure 3.2–Figure 3.14 and in
Table 3.5.
There are four basic categories of audible annunciation: Process Status, FCI Status
Summary, FCI Details, and Button Press. Additionally, a user can select from four
audio modes: Silent, Summary, Row/Column, or Morse Code Mode. These audio
modes are described in DIP Switch Settings.
Process Status
Process Status events are annunciated to provide feedback of SEL-8310 status. Each
type of event is described below.
Power-Up
The Power-Up event is annunciated after a successful Power On Self-Test (POST) is
completed. It is a series of four tones, three short tones followed by one long tone,
increasing in pitch.
