Operator Manual
In the example, the message reports that the TOC level exceeded its specified alarm limit on
Channel #4. In the event of multiple excursions, the date and the time each alarm was detected
are displayed, as well as the total currently logged for the instrument.
Any additional (different) alarms for the Analyzer can be examined by pressing the Up and
Down Keys to scroll through its log. Once displayed, Codes are erased but still available on
the Analyzer’s internal log (see “Internal Log” on page 114 ). The alarm status of the other
Analyzers can be observed by pressing the Alarm Key repeatedly. If no fault conditions exist
for a particular instrument, “No Codes” is reported.
The Alarm Key also is used to acknowledge Anatel A643a Codes. When an Analyzer problem
is detected, it displays the following information:
Fig 7-17 : Acknowledged Sensor Alarm
Line 1 The affected instrument’s Channel ID and its userentered Name .
Line 2 The Code number representing the problem.
Line 3 A brief message describing the nature of the alarm.
