NOTE

Green LED intensity can be adjusted between 0 and 100 % with step of 10 % 
according to the value set in Holding register 80.

Ambient light sensor

The measured light intensity in lux is available in Input Register 41. Additionally, 
an active and standby level can be defined in Holding registers 35 and 36. Input 
Register 42  indicates if the measured value is below standby level, above active 
level or in between both levels:

 

 Ambient light level < standby level: Input Register 42 indicates “Standby”.

 

 Ambient light level > active level:  Input Register 42 indicates “Active”. 

 

 Standby level < Ambient light level < Active level: Input Register 42 indicates “Low 
intensity”. 

VERIFICATION OF INSTALLATION INSTRUCTIONS

After switching on the power supply one of the LEDs lights up according to the 
status of the measured variable. If this is not the case, check the connections.

TRANSPORT AND STORAGE

Avoid shocks and extreme conditions; stock in original packing.
