*I No signal detected No signal detected:
- sensor far from the pipe or
not so coupling
- wrong sensors mounting
- too many oxide or dump
inside the pipe
- new linearity - check the acoustic contact with the
pipe’s surface.
- use another coupling grease
- check initial settings
-
try to reduce the pipe’s internal
dumps or change the sensors
position
- wait for stable linearity.
*H Low strength signal Low signal strength SEE ABOVE
*H Poor quality signal Poor signal quality SEE ABOVE
*Q Freq output power Output frequency bigger than
120%, very high flow rate or
wrong settings. Check again the settings in M66 and
in M69 or simply confirm that the
flow rate should be so big.
*E Over current loop Output current bigger than
100%, very high flow rate or
wrong settings. Check again the settings in M66 or
simply confirm that the flow rate
should be so big.
*F Ref. to table 1 Please find the problem during
initial test. Switch off and then switch on or
contact B.M. Tecnologie Industriali.
