Technical parameters
Power supply: Battery /USB 5V.
Appearance size: 86mm*86mm.
Appearance material: PC+ABS flame retardant.
Working environment: no condensation at -10-50 ℃ and 5-90%RH.
Operation
There is a button at the back of the RuntalAire® A1-EA sensor.
- Turn on the sensor: Press the button once.
- Turn off the sensor: Press the button for 6 seconds.
- On/off the indicator light: Press the button once as the sensor is running.
Connect to the Controller
Please refer to“L-4-EA Controller Manual” for details.
Before connection, please make sure the sensor is on. Set the controller to the sensor connection module. Press S3
+S4
for 3 seconds and the air quality icon (green leaf) in the middle of the controller screen will be blinking.
Press the button at the back of the sensors for 3 times until the indicator light is red and blinking. When the sensor is connected to the controller, the indicator light stops blinking and the air quality icon(green leaf) at the controller will be lighted all the time.
Charging
When the sensor is connected to the USB cable, if the battery power is less than 100%, the sensor will be charged automatically.
The indicator light will blink every 10 seconds and will stop blinking after charging.
Safety instructions
Commissioning and maintenance must be carried out by certified technicians.
During use, it should be kept away from heat sources, high pressure, and not in contact with water. To charge the sensor, please use a 5V charger. It is strictly forbidden to directly connect to high voltage, high current charging, which will flow through the battery and damage it or make the battery heat, smoke, deform or burn.
When not in use for a long time, please store the sensor well. Leave the battery in a half-charged state. During use, if the battery leakage sticks to the skin or clothes, please rinse with water to avoid skin discomfort. In case the electrolyte gets into the eyes, rinse with clean water as soon as possible, do not rub the eyes, and send it to the hospital immediately.
