9.6.Putting into service
To put the weather station into service the following steps must be taken. A connection overview is
shown in the Figure on page 21.
•
Cabling between ALMEMO
®
connector and the sensor
•
Feeding the necessary supply for heating and fan via external mains unit
(via mains unit plug or WAGO terminal strip)
•
Installation of overvoltage arrester (optional)
•
Completing the wiring and then plugging the ALMEMO
®
connector into
the measuring instrument
•
Checking the signal LEDs in the adapter
•
These LEDs and their respective meanings are listed in the following table.
LED
Description
POWER
Signals the status of the external supply voltage
LED active : External supply present
LED inactive : External supply absent or defective
ALMEMO
Signals the status of the ALMEMO
®
supply voltage from the instrument
LED active : ALMEMO
®
supply voltage active
LED inactive : ALMEMO
®
supply defective
FMD760
Signals the status of the sensor supply
LED active : Sensor supplied with 12 or 24 V
LED inactive : Sensor not supplied
Possible reasons : Defect in measuring instrument, mains unit, or sensor
Circuit-breaker in adapter is opened
