7 Anatel A643a Alarms
7.1
General Information
An Analyzer’s TOC level can be monitored for fluctuations, any excursion triggering an alarm
condition. The alarm limit can be independently defined for each instrument.
The user is alerted to any TOC limit excursions on the C80 Controller by flashing its entire LCD
display, as well as the affected instrument’s Channel LED. When enabled, an audible beeper
also sounds to provide additional warning. A hardcopy printout of the excursion is generated
automatically and the Analyzer’s
Digital Output #1 port may be used to transmit its alarm
status to a compatible device (see “Digital Outputs” on page 142 ).
The Anatel A643a alarm reporting facility also is used to report any detected Analyzer problems
such as a defective UV lamp or an excessively low sample temperature (see
“Alarm Codes” on
page 175 ). Summary data on any limit excursion or Analyzer alarms are displayed on the
Controller by pressing the Alarm Key ; detailed information is available on the printout.
7.2
Software Setup
There are two alarm variables which can be defined by the user. The Analyzer’s Alarm Setup
parameter specifies the level of the limit excursion that triggers an alarm condition. Beeper
Setup enables and disables the Controller’s audible alarm.
7.2.1 Alarm Setup
Note:
Default: TOC Alarm/500 ppb
The Alarm Setup parameter enables the alarm limits for the Anatel A643a and, in the case of
a TOC alarm, defines the limit at which the indication is triggered.
