Endress+Hauser Gammapilot M FMG60 - Installation conditions for density and concentration measurement

Gammapilot M
18 Endress+Hauser
Proof-test
Proof-test Safety functions must be tested at appropriate intervals to ensure that they are functioning correctly and are
safe.
The time intervals must be defined by the operator.
Proof-testing of the Gammapilot M must be carried out in accordance with the following procedure.
If several detectors are used in MooN votings, the proof-test described here must be performed separately for
each detector.
In addition, checks must be carried out to ensure that all cover seals and cable entries are sealing correctly.
Testing of internal clock
The device must display the correct date. If the date is out by more than one day, it must be corrected to ensure
correct decay compensation.
Please see also the note in the Section "Behavior of device when switched on" → ä 10.
Testing of Gammapilot M to ensure its safe functioning
During safety testing of the Gammapilot M, the radiation path of the measuring point must be clear.
For testing, the source of radiation is switched off. As a result, the output current changes from 4 mA to
20 mA.
In a second step, the source is switched back on, and the current then changes from 20 mA to 4 mA. This must
be checked by measuring the current using a calibrated measuring device with a accuracy of
± 0.1 mA. If the average value of the current deviates by more than 0.2 mA from the set point, the measuring
point must be recalibrated and this test must be repeated.
"
Caution!
If recalibration and testing are not successful, the device must no longer be used as a safety device.
Please contact Endress+Hauser Service.
This test detects approx. 98 % of all possible dangerous undetected device failures.
!
Note!
Please see also the Section "Maintenance, recalibration" → ä 17.
Repair
Repair All repairs to the Gammapilot M must be carried out by Endress+Hauser.
In the event of failure of a SIL-labeled Endress+Hauser device, which has been operated in a safety function,
the "Declaration of Contamination and Cleaning" with the corresponding note "Used as SIL device in protection
system" must be enclosed when the defective device is returned
Please note the Operating Instructions BA00236F/00/EN, Section "Return" with regard to this.
If the Gammapilot M is equipped with new software, a reset must be carried out following download, and the
device must be tested to ensure that it is functioning correctly and also recalibrated.
