5.3.5 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 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.

5.3.6 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.

6 CONNECTION

The cable glands are designed for cables between 4 mm and 6 mm diameter. Water intrusion may occur if sensors

with cable diameters outside of this range are used.

6.1 PULSE COUNTING

Note:

Refer to the meter manufacturer’s product information for complete information about functionality and connectivity

information.

The counter contact ("Normally Open" or "Normally Closed") must be connected between Tx/Cnt and GND (refer to

CVLog3500 wiring diagram).

7 SIM CARD

7.1 PREPARING THE SIM CARD

A 3FF/Micro-SIM format SIM card is necessary for data communication compatible with LTE cat-M1, NB-IoT, or GPRS.

CLA-VAL can optionally provide SIM card. If another SIM card than the one supplied by CLA-VAL is used refer to chapter

9.7 « Custom SIM Card » for configuration.

7.2 INSERTING THE SIM CARD

Insert the SIM card with the golden contacts downwards into the card holder. Refer to Figure 2 - Chapter 2 « CV-Log-35

Characteristics » and the symbol printed on the CV-Log-35 for correct SIM card orientation. The SIM card must be

completely inserted into the card holder. If the card is overlapping the card holder after insertion, remove it and check the

card’s orientation.

8 STARTING OPERATION

If the CV-Log-35 model implements an internal battery, ensure it is connected to the battery connector on the electronic card

(Figure 2 - Chapter 2 «CV-Log-35 Characteristics»).
