Description:

   of the charging station (binary value).

and is stored in the EEPROM; reasonably usable up to 150. 

 

The answer TCH-OK confirms only the receiving of the command and not the cor-
rectness of the value. 

 

Values between 2 and 9 are not answered (reserved functions). Invalid values (e.g. 
letters) are leading to a deactivation of the relay. 

 

The correct reception can be verified using the proper report. 

 

 

Note 

The controllability is only available if the default function of the output is not activated via the DIP-
switch DSW1.2.
