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
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.
