Installation and electrical connection should be carried out in accordance with local regulations and only by qualified technicians! The protection level is guaranteed only if D35 has been installed by technicians instructed by CLA-VAL personnel and thereafter correctly maintained. During installation and maintenance, the inside of D35 must remain completely dry. Humidity may drastically shorten the life of the battery and electronics.
Installation is not recommended below a value of -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 D35 or deport its antenna with adequate CLA-VAL extension cables.
Communicating Valve Controller ORIENTATION IN SPACE The D35 should be mounted in an upright position (antenna side up, cable gland down) to guarantee a good cellular connectivity. D35 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.
5.3.4 STRANDARD INSTALLATION The standard installation of the D35 on the wall should be, as close as possible to the well opening, but not further than 1.5 m from the pressure sensor(s) connection(s) on the valve. The minimum signal strength is - 80 dBm for optimum data communication at the valve level.
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 D35 can be installed closer to the well opening, while maintaining a maximum distance of 1.5 m to the pressure sensors. If this is not possible, an antenna extension with optional CLA-VAL antenna extension cables might be necessary.
In "Standby" mode you can remove the SIM card or SD card, as well as connect or disconnect physical inputs. The "Acquisition" mode is the operating mode of the D35. In this mode, the device acquires the signals from the connected sensors and inputs and saves them to the internal memory.
CLA-VAL D35 Communicating Valve Controller INSTALLATION VALIDATION The simplest and fastest way to verify the successful start of the product is to use the D35 LED. The LED flashes green every 10 seconds when in "Acquisition" mode. ACTIVATING D35 Once the following actions are performed ...
Choose the transfer interval and the time from which the interval will start. This interval will determine the frequency of communications of the D35 and Link2Valves. Please note that a faster interval will have a negative impact on the battery life of the unit and generate potential additional costs.
Associate the D35 unit with your Link2Valves user account. First, enter the email address of your Link2Valves account. If you do not have one, please contact CLA-VAL to get one for free. Then click on "REGISTER NOW" and wait for the message "Success! ".
Periodic synchronization is recommended. This operation can only be performed if the D35 is connected to the cellular network (option). If not, go directly to step 8.
Communicating Valve Controller Click on "SYNCHRONIZE NOW" to update your unit's clock immediately. This operation can only be performed if the D35 is connected to the cellular network (option). If not, go directly to step 8. Check that the time displayed on the clock below the navigation menu is correct. If not, you can set the time manually in "Manually set date and time".
Click on the "UPLOAD FIRMWARE" button and wait a few minutes. Completely power off the D35 to apply the update. To do so, press the product button for 5 seconds to turn off the WiFi. Make sure the LED flashes green every 10 seconds, indicating that the product is in "Acquisition" mode Then press the main button for 10 seconds to completely switch off the D35 (a red flash appears after 10 seconds) ...
D35 will flash purple for a few minutes. Do not disconnect the power during this time! Note: Before upgrading firmware on a D35, please check on the CLA-VAL website (https://cla-val.ch) for the latest version of the software & firmware. 10 SUPPORT 10.1 MAINTENANCE AND RETROFIT...
