CV-LOG-35 MOUNTING

warning - 1 When mounting a CV-Log-35 with sensors other than those provided by CLA-VAL, be careful not to damage or deform the housing in any way (warranty will become void).

5.1 CELLULAR NETWORK QUALITY
Check the cellular network quality at the installation location prior to installing the product.
Network strength indication from a cell phone gives initial information about signal reception quality on a site. For more accurate information, use the CV-Log-35 configuration mode to get the exact reception quality of the product. Refer to chapter 9.11 « Checking the quality of the network » for more details.
The CV-Log-35 configuration mode will indicate (amongst other things), the network reception quality as seen by the CV-Log-35 in dBm units. Installation is not recommended for signal quality under -95 dBm. As the cellular network quality may fluctuate strongly across the site, it is recommended to test at different locations.
If network quality at the installed location is not sufficient, it may be necessary to relocate the CV-Log-35 or extend its antenna with adequate CLA-VAL extension cables.
The minimum signal strength is – 80 dBm for optimum data communication at the valve level.

5.1.1 NETWORK QUALITY BETWEEN -80 dBm and -95 dBm
If the signal quality at the valve level is between -80 dBm and -95 dBm, check if the CV-Log-35 can be installed closer to the well opening, while maintaining a maximum distance of 3 m to the pressure sensors. If this is not possible, an antenna extension with optional CLA-VAL antenna extension cables might be necessary.

5.1.2 NETWORK QUALITY LESS THAN -95 dBm
If the signal quality at the valve level is lower than -95 dBm, it is required to deport the antenna outside of the well.
Please contact CLA-VAL for more information.

5.2 ORIENTATION IN SPACE
CV-Log-35 should be mounted in an upright position (antenna side up, cable gland down) to guarantee good cellular connectivity.
CV-Log-35 may have difficulties transmitting when submerged (e.g. in a manhole after rainfall).
To guarantee reliable transmission it is recommended to install it as high as possible in the well.
