NOTE
By default, the LED indication refers to temperature measurements. This can be
changed to relative humidity values via Modbus Holding Register 26 (see
Table
Holding registers
below
).
Ambient light sensor
It measures the ambient light levels in order to activate or deactivate
Input Register 6
.
There are two Holding Registers for setting Active or Standby light level in luxes.
■
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”, therefore it is advisable to set Active and
Standby levels in Holding Registers 34 and 35 according to the ambient lighting.
VERIFICATION OF INSTALLATION INSTRUCTIONS
After switching on the power supply one of the LEDs light up according to the status
of the measured variable. If this is not the case, check the connections.
