Instructions for converting Daviteq Sigfox Exd-Pressure device to Daviteq LoraWAN Exd-Pressure device.

1. Prepare tools:

1 pc x Screwdriver

1 pc x 12” Wrench

1 tube x Thread Lock Glue

1 bottle x Cleaning alcohol

1 pc x Cleaning cloth

1 pc x Grinding tool

1 pc x Heat gun

Figure 1.1: Tool list

2. Disassemble the Daviteq Sigfox Exd Pressure device:

Step 1: Unscrew the antenna by turning the antenna counter-clockwise and open the device housing cover by turning the upper housing cover counter-clockwise as a below figure.

Figure 2.1: Unscrew the antenna and open the housing cover of Daviteq Sigfox Exd Pressure device.

Step 2: Grind the excess part inside the housing cover to fit with new LoraWAN main board by grinding tool.

Figure 2.2: Grind the excess part inside the housing cover.

Step 3: Remove the Sigfox mainboard by screwdriver. The position of 3 screws is marked as Figure 2.3.

Figure 2.3: Remove the Sigfox mainboard by screwdriver.

Step 4: Unscrew the antenna cable and cut out the 2 wires connecting the pressure sensor and Sigfox mainboard.

Figure 2.4: Unscrew the antenna cable and cut out the connecting the 2 wires.

Step 5: Heat up the connecting thread between the pressure sensor and housing by heat gun (recommended heat with temperature of 300 oC in 20-30 minutes) to melt the thread lock glue for easy disassembling. Then unscrew the sensor by turning counterclockwise using wrench.

Figure 2.5: Heat up the connecting thread.

Figure 2.6: Unscrew the sensor by turning counterclockwise using wrench.

Step 6: Peel off all labels on the housing of Sigfox device.

Step 7: Clean the housing and thread by alcohol and cloth.

3. Assemble the Daviteq LoraWAN Exd Pressure device:

Note: Only re-use housing, antenna for converting from Sigfox device to LoraWAN device. DON’T re-use the Sigfox mainboard and pressure sensor.

Step 1: Apply thread lock glue to the connection thread and screw the new pressure sensor to the housing by turn clockwise.

Warning: Do not use to too much glue as it will take too long to dry and leak to the mainboard. Recommend using 2-3 drops of glue.

Figure 3.1: Apply thread lock glue to the connection thread of sensor.

Step 2: Select correct LoraWAN mainboard for the sensor in the step 1:- 10 bar new sensor will be installed with LoraWAN mainboard having item code on the main board label of WSLRWEX-PPS-10-01- 100 bar new sensor will be installed with LoraWAN mainboard having item code on the main board label of WSLRWEX-PPS-100-01

Step 3: Note out the serial number on the selected LoraWAN mainboard label for later usage in labelling step.

Step 4: Screw the antenna cable on the LoraWAN mainboard to antenna and plug socket of sensor cable to the socket on the LoraWan mainboard.

Warning: Arrange the wires neatly to avoid the wires being stuck.

Figure 3.3: Screw the antenna cable and plug socket of sensor cable.

Step 5: Fix the LoraWan mainboard to the housing in the position as shown by screwdriver. The position of 2 screws is marked as Figure 3.4.

4. Stick labels on the housing of Daviteq LoraWAN Exd Pressure device:

There are 4 types of labels for the LoraWAN Exd Pressure device: 1 x LoraWAN label, 1 x Device information label1 x Magnet reed-switch label1 x Manual QRCode of Daviteq LoraWAN Exd Pressure firmware3 device label And 4 types of label and LoraWAN mainboard in the package.

Step 1: Screw the housing cover tighty then stick the LoraWAN label vertically. The direction of the label as Figure 4.1.

Figure 4.1: Position and direction of the LoraWAN label on the housing cover.

Step 2: Stick the device information label at the position at Figure 4.2.

Note: Make sure the serial number on the label is the same as one on the main board label. The serial number on the mainboard label is noted out in step 3 of section “3. Assemble the Daviteq LoraWAN Exd Pressure device”

The the device information label is next to sensor mounting semi-circular hole.

Step 3: Stick the magnet reed-switch label as position as Figure 4.3.

Figure 4.3: Position of the magnet reed-switch label on the housing

After completing labelling, the sensor will be as below figure 4.4.
