Setting up an ECD
WARNING
To assure that removable radioactive contamination on the external parts
of the ECD remain at a safe level, the United States Nuclear Regulatory
Commission requires that:
• the ECD is Wipe Tested at least once every six months and
• a record of the results are maintained for NRC inspection.
Please refer to the Hardware Guide, Maintenance chapter, for the
Wipe Test procedure.
NOTE: THERMAL RUNAWAY PROTECTION: The Clarus GC software
shuts down the GC if any heated zone exceeds 470 °C. Should this
occur, the following error message is displayed:
INSTRUMENT SHUTDOWN
xxxxx THERM RUNAWAY
....where xxxxx is the heated zone.
Call your PerkinElmer Representative.
Instrument shutdown also occurs if there is a PRT (Platinum
Resistance Thermometer) or MPU (Micro Processor Unit) failure.
In these cases the following error message is displayed:
INSTRUMENT SHUTDOWN
xxxxx PRT ERROR
....where xxxxx is the failed zone.
Call your PerkinElmer Representative
NOTE: The detector gas modules have been set to OFF at the factory for both
manual and PPC pneumatics.
United States Government Regulations for ECDs
