Register 6 indicates if the measured value is below standby level, above active level
or in between both levels:
■If the measured light level is below the Standby level, Input Register 6 indicates
“Standby”.
■If the measured ambient light level is above the Active level, Input Register 6
indicates “Active”.
■If the measured ambient light level is between the active and stand-by level, Input
Register 6 indicates “Low intensity”. When this feature is used, it is advisable to
adjust the active and standby levels in Holding Registers 34 and 35 according to
the actual ambient light conditions around the sensor.
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.
