COMMISSIONING AND TRANSMISSION TIME INTERVAL SETTING
To ensure that the measured values of the sensors are correctly evaluated at the receiver, it is necessary to teach the devices into the receiver.
This is done automatically using the "Learn" button on the sensor or manually by entering the 32bit sensor ID and a special "teach-in procedure"
between transmitter and receiver. Details are described in the respective software documentation of the receiver.
To access the Learn button, turn the sensor cover counterclockwise
and remove the cover.
The learn button is located on the bottom of the motion sensor. The
exact positioning is shown in the figure on the right.
Setting of transmission time
Before opening the device, disconnect it from the power supply!
Factory default: T_wake up: 100, T_intervall: 10
Transmission time = 100 seconds (T_wake up) x 10 (T_intervall)
= 1000 seconds = approx.16 minutes
Note fort he battery operated device:
The transmission frequency
also has a direct influence on the operating energy available in the
energy storage device and thus on the discharge time of the energy
storage device during operation.
