Operation

The system status panel operator is only capable of viewing the system operating status on the LCD
display. The following paragraphs provide a general overview of the system status panel features. Push-
button switches provided on the system status panel are assigned specific system control functions.

Push-Button Switch Summary

Each push-button switch function is assigned a specific function. The following describes the function(s)
of each switch on the front panel of the system status panel:

A

CK

/N

EXT

– the ack/next push button performs three unique functions, each of which is dependent upon

system status or conditions. The 1

st

function is an illuminated state which indicates unacknowledged

event(s) or condition(s) in the system. The 2

nd

function is an acknowledge function, which when

depressed is used to acknowledge an event, causing the switch lamp to extinguish (if there are no other
unacknowledged events). The 1

st

and 2

nd

functions are sequenced repeatedly as long as outstanding

events or conditions exist. The 3

rd

function (next) is available only when all events or conditions are

acknowledged. The next function is used in conjunction with the previous push-button to navigate
forwards and backwards, respectively, through the history buffer of messages.

P

REV

– is an abbreviation for previous and is used in conjunction with the next function (of the ack/next

push-button switch) to navigate forwards and backwards, respectively, through the history buffer of
messages.

F

AULT

/R

ESET

– the Fault/Reset push-button switch used to reset active alarms displayed on the LCD and

fault relay outputs at the ADVANCE System control cabinet, which are retained until the faulted
condition is corrected.
