6. TROUBLESHOOTING
Simtronics shall do all service and repairs. Troubleshooting ashould be performed by the
used as described below.
The detector can also give fault messages if the mounting brackets are not sufficiently
stable over time, for example with temperature changes or passing trucks resulting in the
GD1 coming temporarily out of alignment. Before troubleshooting is commenced the
rigidity of the mounting structure should be checked.
The most common issues are the following:
•
Misinterpretation of ppm*m as ppm. Described in section 10.4.
•
Poor alignment. Please be aware that it is the absolute transmission that should be
optimized, not the relative transmission (section 3.3).
•
Interference from a second transmitter as described in section 6.3.
Troubleshooting should always start by inspecting the detector’s lens es for contamination
and/or defects. The following list may be helpful:
Issue
Possible source of
problem
Suggested correction
Clean optics
warning
(3 mA) Dirt on lens. Clean optics (see section 5.2).
Detector out of
alignment.
Realign detector (see chapter 0).
Beam block
(2 mA)
Dirt on lens. Clean optics (see section 5.2).
Detector out of
alignment.
Realign detector (see chapter 0).
Objects that block the
measuring path.
Remove objects that block.
Detector in alignment
or service mode
Reboot detector by Service Interface
(Ethernet), HART®, or by
cutting/reconnecting power.
Fault
(1 mA)
Check error code in
the Service interface
Status screen.
See section 0 for a description and
suggestion on how to solve the issue.
No Power
(0 mA) No power to the
detector.
Verify with multi meter in the Junction box
that detector has power.
Check both detector and system cable
wires on terminal 1 and 2 in the junction
box.
No wireless or
cable Ethernet
connection
Not connected to
