5.0Routine Maintenance

5.1Automatic operation and routine operational duties

Thesystemoperatescontinuouslywithoutadjustment. Undernormalcondi- tions,afteryouprogramthesystemforautomaticoperation,onlyroutinemaintenance procedures are necessary. The most common failure condition is a temporary interruptionofthepowerservingtheinstrument. Ifthepowerserviceisinterrupted,the sourcelampintheanalyzerwillrestartautomaticallyaslongasthereisnodefectinthe lamp circuit or its starter.

Whenthe alarm circuit is powered independently from the analyzer power source, the alarm circuitisfail-safeandwilldetectpowerfailure.

A message such as "Cell Fail check the detector signal"might be displayed if a 1amp off condition occurs

5.2System Visual Check and Response Procedure

1.Verifythatthesignalfailurealarmisnotinfailurecondition.

2.Verify that the zero and span control setting have not been disturbed.
