Acknowledging Fault or Isolate Conditions

How the 4100ES
Indicates the
Presence of a Fault
or Isolate condition
What Acknowledge
Does
When a Fault or Isolate condition is present in the 4100ES, the operator interface does the
following:

The yellow "FAULT" or "ISOLATE" indicators flash.

The sounder (buzzer) sounds steady.

The display on the interface panel indicates the first Fault or Isolate condition, as shown
below, and the most recent condition as well, if there are several:

The first step in managing a fault or isolate condition is to acknowledge the condition.
Acknowledging a fault or isolate condition does two important things:

It records the time and date at which you observed the presence of the condition and
stores that information in the system's historical log.

When you press the <FAULT ACK> or <ISOLATE ACK> key, the system displays
specific data on the location of the condition. (In the case of Isolate it gives confirmation
on the LCD that you have isolated the correct zone).
