3. Installation<br />
Note: Be<strong>for</strong>e actioning any installation observe the 'Safety in<strong>for</strong>mation' in Section 1.<br />
To meet its specified accuracy and per<strong>for</strong>mance it is essential that the following installation<br />
guidelines are followed carefully. For steam applications sound steam engineering practices<br />
should be followed, including the use of separators. The installation must con<strong>for</strong>m to all<br />
relevant construction and electrical codes.<br />
There are three parts to the installation of the <strong>TVA</strong> flowmeter <strong>with</strong> WirelessHART TM :<br />
3.1 WirelessHART TM commissioning (Device based).<br />
3.2 HART TM gateway installation - Page 14.<br />
3.3 Mechanical installation - Page 18.<br />
It is advised that the device based HART TM configuration is carried out on a workbench<br />
be<strong>for</strong>e the flowmeter is installed into a pipeline (mechanical installation).<br />
3.1 Device based WirelessHART TM commissioning<br />
Quick start commissioning guide<br />
For commissioning, the device can be powered by the TEG10 or a standard dc supply, wired<br />
to the internal green power connector (located inside the enclosure).<br />
The device’s parameters are modified using a HART TM user configuration tool connected<br />
to the maintenance port located inside the enclosure. When communications have been<br />
established the device automatically enters the commissioning mode.<br />
During commission mode:<br />
- MODBUS communication to the flowmeter will stop.<br />
- The device will not update the wireless gateway <strong>with</strong> the current steam flow data.<br />
- If power is being supplied via the internal green power connector, the flowmeter will<br />
remain switched off (i.e. the front panel display will not illuminate).<br />
- If power is being supplied via the TEG10, the flowmeter will power up and will continue to<br />
update the total flow internally. It will not transmit the current total flow wirelessly.<br />
The device will automatically enter the run mode, 60 seconds after the configuration tool has<br />
been disconnected or has been exited. The gateway will be updated <strong>with</strong> the current flow<br />
data and parameters.<br />
Equipment required:<br />
- HART TM configuration tool: Communicator or PC / PDA / Smart phone, DD based host and<br />
a HART TM modem (drivers to be installed).<br />
