Troubleshooting
The analyzer incorporates extended diagnostic and reporting to inform the user about the nature of a
problem.
Alarm codes, with user-initiated diagnostic tests, serve to isolate the source of the problem. The
analyzer constantly monitors its operation and measurement values for alarm conditions.
Alarm conditions include error alarms, critical error alarms, warning alarms and measurement
alarms.
Alarms
Alarm indication
The analyzer has two basic operational modes: online and bottle. The online TOC and conductivity
are the two primary online modes. In online TOC and conductivity modes, the measurement screen
shows an animation that identifies the general state of water flow through the analyzer.
In online TOC, conductivity, or manual TOC modes, the animation area is also an alarm condition
indicator. When an alarm occurs in an online mode:
• The animation area flashes red.
• The value of the variable that has caused the alarm becomes red.
• The alarm sound
**
is heard if enabled.
• The alarm condition is recorded to the data log and audit trail.
• The alarm icon is enabled.
• Error, critical error or warning: The digital output that represents the error state identifies an error
condition. Refer to Configure the digital output alarms on page 31.
• Error or critical error: The three analog outputs identify an error condition (2 mA or 22 mA). Refer
to Configure the analog outputs on page 33.
**
Each type of alarm (stop, warning, alarm) has a different sound. If multiple alarms occur, only the
highest-level alarm is heard.
