Warning:
Do not work on the system unless the power is switched off or
isolated.
Caution:
Ensure that anti-static handling procedures are observed applied
when working on the system, i.e. Anti- Static Wrist Straps
Warning:
The Invalidate Guarantee label around the Detector Head is fitted
to ensure that the Detector head is not tampered with. Any attempt
to remove or disassemble the head will void the warrantee and may
affect the detector calibration settings requiring the Detector Head
to be replaced.
Prior to conducting maintenance on the OMD system it is recommended to isolate the
Slowdown/Shutdown Relays and the detectors being maintained. In addition, if the detector head is to
be removed from the base the detector cable should be detached from the detector.
Isolating the relays will ensure that an alarm condition, which may occur during maintenance, is not
transmitted to the AMS.
Isolating the detector will ensure that faults or alarm, which may occur during maintenance, are not
indicated on the Control Panel.
Disconnecting the detector cable from the detector will ensure that light entering the sample chamber
does not result in a backup alarm being initiated.
