Is there a list of CL17 Chlorine Analyser alarms and warnings?
Summary
Alarms and warnings for the CL17 Chlorine analyser.
Answer

System Alarms

 
EE Error – indicates inability to write to the EEROM.  Displays “Error Exit to Restart”  Exit key will restart the analyser, however if the problem has not been resolved the instrument will likely fail again.
 
A2D Error – indicates Reference measurement = 0 A/D counts.  Displays “A/D Error Exit to Restart” and Alarm LED is lit.  Exit key will restart the analyser, however if the problem has not been resolved the instrument will likely fail again.
 
LED Failure – indicates Reference measurement less than 100 counts.  Displays “LED Error Exit to Restart” and Alarm LED is lit.  Exit key will restart the analyser, however if the problem has not been resolved the instrument will likely fail again.
 
Motor Failure – indicates home position flag not detected.  Displays “Motor Error Exit to Restart” and Alarm LED is lit.  Exit key will restart the analyser, however if the problem has not been resolved the instrument will likely fail again.
 
SCR Error – indicates the cycle (pump) motor does not turn off resulting in a short total cycle time.  Displays “SCR Error Exit to Restart” and Alarm LED is lit.  Exit key will restart the analyser, however if the problem has not been resolved the instrument will likely fail again.  If software version is V1.3 or earlier, main circuit board should be replaced.
 
When a System Alarm occurs, the normal functioning of the analyser is halted and the alarm message is displayed.

 

System Warnings

 
Power – indicates power failure has occurred.  The default setting for this warning is disabled. 
 
Low Signal – indicates Reference measurement is less than 5000 A/D counts.  A “Low Sig” message is momentarily displayed.  Normally indicates a need to clean the sample cell.
 
Marginal Gain – indicates a calibration resulted in a gain correction factor greater than 1.1 or less than 0.9.  A “Marg G” message is momentarily displayed.  If the gain is greater than 2 or less than 0.5 the calibration is not accepted. 
 
Marginal Zero – indicates a calibration resulted in an offset correction greater than 0.2 and less than 0.5.  “Marg Z” message is momentarily displayed.  If the offset correction is 0.5 or greater, it is not accepted.
 
System Warnings are indicated by a “Sensor Warning” message on the status line of the display.  To recall the warnings, use the Recall Warnings” function in the Alarm Menu.  Any active warning will be momentarily displayed. To clear the warnings, use the Clear Warnings function in the Alarm Menu.
