FUG1010 IP65 NEMA 4X Quick Start
Operating Instructions, 06/2014, A5E02951527-AC
Probable Cause
During the Initial Makeup the flow
meter decides that the level of the
receive signal is insufficient for proper
operation.
If it appears that the flow meter cannot
complete an Initial Makeup it means
that the pipe and/or gas conditions do
not permit a receive signal that meets
the flow detection standards. The
system will not operate.
Troubleshooting
5.1 Troubleshooting
Solution
Some reasons for low signal are:
Invoking [Install completed?] on a
•
pipe with insufficient pressure.
Coupling compound insufficient; not
•
applied or evaporated.
A disconnected or broken sensor
•
cable.
The pipe needs to be conditioned at
•
the mounting location.
Insure that line is sufficiently
•
pressurized.
The sensor cables are defective or
•
not connected to the correct
channel.
If you locate and correct the improper
condition immediately, press <ENTER>
to resume the installation procedure.
Otherwise, press the <Left Arrow> to
abort the installation and conduct a
thorough investigation.
Attempt to improve operating
conditions by reinstalling the sensors at
a different spacing offset, or even at a
different location on the pipe.
Switching from Reflect to Direct Mount
may solve the problem. However,
operation may not be possible if there
is insufficient line pressure or high CO
gas content.
