NOTE
By default, the LED indication refers to temperature measurements. This can be
changed to relative humidity or CO

values via Modbus Holding Register 79 (see
Table
Holding registers
below
).
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:
■
If the measured light level is below the Standby level, Input Register 42 indicates
“Standby”.
■
If the measured ambient light level is above the Active level, Input Register 42
indicates “Active”.
■
If the measured ambient light level is between the active and stand-by level, Input
Register 42 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.
