6 Service and Maintenance
6.1 Maintenance
The sensors of the TCM series as well as the electronics of the TCE8000 series do not require regular
maintenance.
In case of abrasive or sedimenting media however it is recommended to return the measuring system
to KEM after 8,000 hours of operation for re-calibration and pressure test. This interval may be shorter
when the medium is extremely abrasive or sedimenting.
For best performance we recommend checking the calibration every 5 years, in harsh environments
even more frequent.
If for the specific application an obligatory calibration is required, refer to the corresponding national
regulations for the necessary calibration intervals.
6.2 Trouble shooting
In case the Tricor does not work properly, first check the following items:
No display, no LED lighting
All cables properly connected?
 Connect the missing cables
Power supply switched on?
 Switch on the power supply
Display positioned properly (compact and wall mount only)?
 Remove the display and reset it properly
Internal fuse of the TCE blown?
 For checking and changing the fuses refer to chapter 6.3.
Output frequency too high or unstable
Most probably EMC problems
Shield and ground properly connected?
 Connect shield properly. If necessary, try additional means of grounding and shielding
Unstable flow reading with (theoretically) stable flow
Gas bubbles or solid particles in the medium?
 Mount the meter with the correct orientation
Strong external vibrations?
 Decouple the meter from the vibration source
Flow or pressure slugs in the medium?
 Decouple the meter hydraulically
No frequency or current output with operating display
Output correctly wired?
 Correct the wiring
Output correctly configured?
 Correct the configuration
Wrong flow direction (Flow in the display is negative)?
 Change flow direction
