Operation and Maintenance
6.3 Wiring Instructions
All detailed information about wiring is stated in the UFM Series 6 Wiring
Instructions, as well as UFM Series 6 Safety Instructions ( see Appendix I
– References). Please refer to these documents for correct wiring.
6.4 SPU Configuration
When the meter is installed and correctly wired, it is advisable to read out the
parameter settings of the meter. If the meter has been calibrated before, the
parameter set-up should be compared to the one of the calibration.
The parameter set-up can be read with the software package SonicExplorer.
Connection should be made through the Ethernet or VDSL communication,
more detailed information about this matter can be found in the manual of
the software packages. When discrepancies are detected; contact Elster or
your local representative immediately.
6.5 Cold Commissioning
During cold commissioning the meter is pressurized with a known gas
composition at a known temperature and pressure, because in the case of
atmospheric (low pressure) conditions, the UFM is not able to measure
correctly.
A thorough functional test is performed by means of a PC and diagnostic
software package (SonicExplorer). Diagnostics and status per measuring
path and the zero flow can be checked, assuming there is sufficient pressure
in the meter. A technician of Elster will, if this has been agreed, verify
measurements and check the system performance.
When opening the SPU (either main or rear compartment), obey
the rules and regulations that apply to hazardous area operations.
