2 Mounting Guidelines

ERS Display Series Operating manual

Common mounting guidelines for ERS Display Series line of sensors: · Place the sensor in an open space on the wall, with an installation height of 1.6 meters.
· For best RF and measurement performance, make sure you mount the sensor with the ventilation openings vertically. See installation in chapter 3.
· Make sure that the sensor is not placed in direct sunlight, close to heating vents, near windows, air ventilation where it may measure values that is not representative for the rest of the room.

2.1 Motion PIR
The PIR can self-trigger if sensors are placed too close to each other. Keep this in mind when you mount or test the sensors.
2.2 Sound Level
Think carefully about the placement of the sound sensor. If the sensor is placed close to loud sources such as machines or ventilation, it will be reflected in the sensor readings due to sounds being louder close to the source.

ERS Display Series Operating manual

5.1 Display
The ERS Display series sensors have a 2.13" E-paper display, which keeps the onscreen information even if the sensor is unpowered.
The display will have four different modes depending on the current state of the sensor. Factory mode: If the sensor is not yet started. See figure 1. Join mode: When the sensor is trying to join the network. See figure 2. Standard mode: During normal operation, the layout and values presented on the screen will depend on the sensor model and configuration. See figure 3, 4 and 5. Low Battery mode: If the sensor detects that the battery voltage is getting close to the limit of operation, the sensor will set the screen to display information that the battery needs to be replaced. It will not recover from this mode until the batteries are replaced. See figure 6.

6 Sensor Behavior

ERS Display Series Operating manual

6.1 Sensor Startup
1. The display will be set to factory mode before the sensor is powered for the first time.
2. When the sensor starts, it loads configuration parameters stored in the NFC chip. The sensor will then write all configuration parameters back to the NFC chip.
3. When the configuration is done, the sensor tries to join the network if OTAA (Over the Air Activation) is enabled. Ensure that the sensor credentials (DevEUI, AppKey, JoinEUI) match the keys added to the server to activate the device. The join procedure starts at spreading factor 7 with a join request every ~15 seconds. The sensor will gradually increase the time and the Spreading Factor between the following join requests until the join is successful. An orange LED blink indicates every join request. The sensor starting the join procedure will be indicated on display with the join mode screen.
4. After a successful connection to a network, the sensor sends an uplink containing the sensor settings and enters sampling mode. The screen enters its default mode of showing sensor data.

6.2 Sampling mode / Periodic measurement
The sensor makes periodic measurements according to the user configuration

6.3 Scheduled Transmission
The sensor transmits the data according to the user configuration. However, the configured sending interval can be overridden by network limitations. Due to this, the spreading factor and sending interval settings might result in longer intervals than intended.

6.4 LED Indication
