1010FMA-61 Errata
Error or Message Probable Cause Solution
•
Recouple sensors with fresh
couplant.
•
Install Sensors in Direct mount
mode.
•
Note: If problem persists call
Tech support.
- - -F - - -Fault Alarm •
Loss of signal signal strength
•
Change of Rx signal location (Beam
Blowing)
Re-space Index
The measured liquid sonic velocity
(Vs) is more than +/- 25 % of the av-
erage Vs range. •
Ensure proper pipe dimensions
and/or Liquid data entries are cor-
rect.
•
Properly enter correct Sensor
Size into meter [Install Sensor]
menu.
•
Confirm sensor spacing is cor-
rect by checking [Install Sensor]
menu spacing parameters.
This may be due to one of the fol-
lowing:
•
An out-of-range data entry.
•
An invalid condition; (e.g.,
overlapping sensors in Reflect
Mode). If selecting Direct Mode
does not resolve, review all site
setup and sensor installation
choices; particularly data en-
tered for the pipe and liquid.
•
In Reflect Mode, the flow
meter detects that the pipe wall
signal may impinge upon the
liquid signal. Use Direct Mode
instead.
Trigger <ENTER>, <UP Arrow>,
<DOWN Arrow>, or <LEFT Ar-
row> to abort install routine. Con-
tinue programming other site data
in anticipation of resolving the dif-
ficulty later. Call technical support
for help if necessary.
During the Initial Makeup, the system
detects invalid sensor spacing, erro-
neous liquid/pipe parameters, or
some other factor that prevents it
from completing the Initial Makeup. Invalid Setup (use Direct Mode)
