9. For the re-installation of the
ViscoSense
®
3
sensor in the sensor housing please follow the
instructions in chapter 6.
As it is important to install only one original o-ring, please verify that no parts of the old
o-ring are left behind in the housing. Using other o-rings than original VAF o-rings can
cause misreading of the sensor.
9. REPAIR OR REPLACEMENT
9.1 REPAIR
The
ViscoSense
®
3
sensor and interface box cannot be repaired on site.
They will be either exchanged for a spare unit or send back to VAF Instruments.
9.2 REPLACEMENT
When the sensor or interface box is replaced, we refer to chapter 5 and 6 for unpacking and
installation instructions.
If the sensor is replaced, this will require that the correct settings for this sensor are made in the
interface box. To make the correct settings, a spare sensor is supplied together with an micro SD
card, which can be connected into the interface box.
Please note that the power supply should be connected to the interface box, when
using the SD card.
Please take necessary precautions to avoid personal injury.
9.3 PROCEDURE FOR USING THE MICRO SD CARD
1. Disconnect power supply to the interface box
2. Open the interface box
3. Insert the micro SD card in the interface box into the SD Card slot. Please note that it is hinged,
and therefore it should be pulled back (white arrow) before it can be lifted upwards (fig. 14)

4. Connect power supply to the interface box
5. The settings of the new sensor are now uploaded to the pcb.
6. Close the interface box and the system is ready for use. The SD card is meant to be used for 1
specific sensor only, and can remain inside the interface box.
