4.7.2 Procedure for teach-in without constant light control

The TeachIn process at presence detectors without constant light control is for correcting the
measured value.
The process is as described below:
1. Adjust the para eter Tea hI
The best way doing the Teach-In process is to darken the room and switch the artificial lights
on. Now the brightness must be measured via a luxmeter and the measured value must be
set for the parameter Tea hI
2. Adjust the Para eter Use Tea hI
values to hold TeachIn values .de ge ü s hte Wert.
3. Co e t the o je t 1 -Cali ratio start
activated via the ETS (Group monitor) or with a push button.
4. Download the application.
5. Activate the Teach-In function by sending a logical 1 to the object 18.
6. Now the presence detector has adopted the adjusted value as new measurand and corrects
its measurement from now according to the TeachIn value.
