5 Troubleshooting 

 
 

Osmetech OPTI™ System

 

 

 
The Osmetech OPTI™ 1 and Osmetech OPTI™ CCA analyzers are equipped 
with sensors and diagnostic software that control, monitor and detect analyzer 
system status.  Operator messages indicating system status are displayed to 
provide the operator with useful information to determine the cause of detected 
system errors or malfunctions.  System errors are also stored in memory and an 
error report can be printed that lists the last 50 status messages. 
 
 

 

Displayed Alarms 

 

There are four types of displayed system status messages: 
 

   SYSTEM 

STOP 

ALARMS 

 

These alarms indicate system conditions that must be resolved before system 
operation can be continued. 
 
SYSTEM ERROR ALARMS 
 
These errors occur during sample analysis and are specific to the current sample 
being analyzed.  Error alarms indicate the status of the current measurement or 
additional required operator entry. 
 
SYSTEM WARNING MESSAGES 
 
System warning messages notify the operator of conditions requiring operator 
intervention to complete the current measurement. 
 
SYSTEM INFORMATION MESSAGES 
 
These messages describe operator instructions or confirm completion of operator 
selections. 

 

The following section describes each displayed message and the causes and 
conditions that generate this message.  Further in the chapter probable causes and 
fault isolation are provided for each status message.
