Assembly and commissioning

2.1 Mandatory pre requirements
Network infrastructure is not included in the scope of delivery. Before installing the sensors, please ensure that an adequate and sufficiently robust network infrastructure is available and working properly, namely: the LoRaWAN backend and the associated management software are functional, the gateways are switched on and there is a stable Internet connection established between the gateways and the backend.
2.2 Installation requirements

Warning
Read carefully and keep the user manual for future reference. The Product, as referenced in this manual, comprises the complete hardware components for the Parking Lot Sensor, including the Cap, Screw, Core and Base.
Follow these instructions and all information.
⇒ The Customer must comply with all applicable laws and regulations for the installation and operation of the Product, and if necessary, obtain necessary approvals. The Customer must take appropriate measures to avoid injury of third parties, for example, by them tripping over the Product.
Therefore, the Product should only be installed in a clearly designated parking space and should not, for instance, be installed on the sidewalk.
Prior to starting the installation work, please ensure that all Product components (see Fig. 1 Parking Lot Sensor with TPS110 sensor core), as well as required tools and material, are readily available.

2.3 Installation of the sensor base
Precaution
To ensure safe installation:
⇒ Do not install the sensor core (black part) into the sensor base (grey part) before the final installation of the sensor base on the ground.
⇒ Do not screw the sensor base on the ground!
⇒ Do not drill holes in the base!
⇒ Do not bring a magnet near the PLS (this would power-on the device).
⇒ Avoid uninstalling and reinstalling the sensor core after the initial installation into the sensor base.
⇒ Do not open the sensor core!

The sensor base must be fixed to the ground (substrate such as concrete, asphalt) with a two-component adhesive from a leading supplier (e.g., DELO®, 3M®, …).
Customers have reported good experience with the following adhesive: DELO®-PUR 9692 (universal 2-component polyurethane adhesive available in 50 ml and 200 ml cartridges).
Required material for installing the parking lot sensor

1. Disposable gloves (protection against contact with adhesive)
2. Two-component adhesive
3. Adhesive press (these differ, depending on the cartridge size)
4. Mixing tube
5. Tape rule
6. Sensor base
7. Sensor core (sensor)
8. T20 screw
9. Sensor cap (sensor sealing cap)
10. Appropriate tool to clean ground surface (e.g., broom, air blower)

INFORMATION:
For the bonding procedure, please follow the instructions of the adhesive manufacturer (e.g., temperature, safety information and work instructions).
A prior cleaning of the relevant place of installation (parking slot) should be clarified in advance with the operator of the premises so that the treatment does not result in removal of existing coatings.
Preparation of the parking space
The parking space must be free of dirt, dust, oil, water and other contaminants.
It is recommended to clean the surface to remove contamination using a high- pressure cleaner and a burner. The PLS must be installed in the center of the parking space (intersection of the two diagonals, see Fig. 3) in order to ensure optimum sensor accuracy.

To provide the adhesive with a closed substrate, the ground surface must be free of any gaps or misalignment (see Figure 4 Available parking space for sensor installation). This is not only crucial for the contact surface and the adhesive effect of the product, but also to avoid structural issues when a car runs over it.

Do not install the product on an unstable or uneven ground surface, like interlocking paving stone or directly on the bare ground. These installations can harm the product!

The bottom of the base has been processed with a plasma treatment to improve the adhesion of the glue on the ground:

Take out the base of its protective wrap only just before putting down the adhesive there.
Do not touch the bottom side of the base with your hands or anything else.
Do not put the base on the ground before gluing, to avoid dust on the sensor base.
  Ensure that all parts of the PLS will be protected and will be kept clean until the installation has been completed, so that these parts will be used only within the described intended use.
Check that the adhesive is compatible with the ground and the base of the sensor.
  Ensure that sufficient adhesive is uniformly spread over the bottom side of the sensor base.

Prepare the adhesive following the manufacturer instruction.
Please note that, as soon as the two components are mixed, the adhesive cures within a few minutes.
Do not try to save adhesive by adding less adhesive per sensor base!
First, insufficient quantity of adhesive may subsequently lead the PLS to detach from the ground and the PLS may get lost.
Second, if the adhesive is not uniformly spread-over the base, it could lead to localized stresses and therefor to structural damages when a car runs over the product.

Once all precautions have been taken, you can proceed with the fixing of the sensor base to the ground (by applying light pressure on it. See Fig. 8 Sensor base attachment). Make sure that the sensor base is thoroughly and uniformly fixed flat against the ground, that the base is centered in the parking space and that the Bosch logo on the sensor base points towards the access road (see Figure 9 Sensor base installed). Subsequent twisting of the sensor base is not possible.

Please follow the adhesive manufacturer’s recommendation regarding the cure time of the two-component adhesive.
To prevent damages to the sensor base, keep the parking space unused (no car or engine running over the PLS) until the sensor installation is finalized.
We recommend installing several sensor bases first and only then inserting the sensor cores.
2.4 Installing the sensor core

An improper installation could impact the seals and cause water to get into the sensor which will lead to damages. A smooth and continuous operation of the parking lot sensor is at risk if the PLS is not properly installed.

Do not install the PLS when it is raining or snowing.
Ensure that the inner side of the sensor base is completely dry and without impurity (i.e., dust, mud)
before installing the sensor core.
Make sure that the sealing rings on the cap and sensor are seated correctly.
Do not use damaged components and only use original replacement parts.
Do not open the sensor housing!
Risk of explosion: extreme heat can damage the battery and the sensor.
Do not expose the sensor to temperatures above 85 °C!
Do not expose the sensor to open flames!
When using a gas burner (for example, when removing weeds), keep a distance of at least 1.50 m between the flame and the sensor!
The sensor can be screwed into the base after the adhesive has cured. Before the insertion, use an air-blower to clean the base of any residual dust. To simplify insertion, the arrow on the bottom of the sensor points towards the Bosch logo (see Figure 10 Installing/screwing in the sensor). The sensor should be completely screwed in to ensure optimum teaching of the sensor. To tighten it, use the T20 screw and a T20 screwdriver and tightening torque of 1,8 to 2,2 Nm. Close the opening with the sensor sealing cap afterward.

Respecting the insertion process described above is necessary for an easy and smooth installation, and to ensure that the core is correctly placed into the base for a good watertightness.
Respecting the tightening torque is important to avoid damaging the screw pitch of the base.
Insert completely the sensor core into the base before screwing!
Do not install the core with your feet!
Do not use a blunt object (like a hammer) to insert the core into the base!

INFORMATION:
After the installation of the sensor, it will take approx. 2 minutes before the first measurements are carried out. During operation, a continuous automatic calibration of the parking lot sensor takes place through parking changes (i.e., “parking” and “exiting parking space” events), which happens in its vicinity.
The sensor is fully operational only after at least 10 parking events have been fulfilled with passenger cars or light commercial vehicles.
2.5 Replacing/removing the sensor
In case the sensor core has to be replaced at a later moment in time (for example in case of end-of-life of the battery), you have to remove the T core cap and loose the T20 screw; then remove the sensor core from the sensor base. Should the replacement be done due to physical damages to the PLS, please carefully inspect the sensor base for visible damages prior to installing the replacement sensor core. Replace the whole PLS where required.
The screwing path will show signs of wear after multiple screwings of the core into the base. Consequently, we strongly recommend to change the whole PLS after three replacement/removing actions.
INFORMATION:
The battery is not eligible to a stand-alone replacement. At battery end-of- life, the whole sensor core must be replaced.
To completely remove the PLS from the parking space, while not damaging the ground surface, it is necessary to use a hammer and chisel to destroy the adhesive effect by chiseling the sensor base parallel to the parking space surface.

If the sensor is not working as expected and investigation is needed to understand the issue, please contact the BOSCH customer support by email with these elements:
⇒ Device EUI
⇒ log file containing RSSI, SNR, Join requests, debug messages, spreading factor
If physical analysis of the sensor is required, the support team will send you the return procedure.
Do not attempt to open the sensor by yourself, as this device contains a LiSOCl2 battery. Also, this behavior makes the task harder for our expert team to analyse the problem and, therefore, make the warranty completely void for the opened sensor core. This implies that there would be no warranty replacement for the opened sensor under any circumstance.
2.6 Setup and operation of the parking lot sensor in the backend
In order to set up the sensor in the LoRaWAN backend, the following information is required, which will be provided to you:

• DevEUI (for example, FCD6BD0000190001)
• AppKey (for example, 00112233445566778899AABBCCDDEEFF)
  AppEUI/JoinEUI:

Table 1 AppEUI per sensor variant
Network Quality of Service is extremely dependent on product environment and usage. Customer or customer’s network operator is the best stakeholders to configure the LoRaWAN network.
The customer must verify that the network performances are good enough to operate the Parking Lot Sensors. After installation, the customer must monitor network performances in order to proceed to potential improvements.
At least, the following values should be monitored:
⇒ RSSI which should be higher than -120dBm.
⇒ SNR which should be higher than -7dB.
⇒ Number of SW resets from the device, that should be exceptions (method to get this value from the sensor is described in the PLS Communication Interface that could be communicated on request).
The number of gateways should be higher than two (to manage unexpected unavailability of one gateway). This number should also be proportionate to the number of installed sensors and to the maximum of expected simultaneous parking events. We recommend to install at least a minimum of two gateways for smaller projects to get the appropriate network coverage redundancy. For bigger projects with higher number of installed sensors, add the appropriate number of gateways.
