VERIFICATION OF INSTALLATION INSTRUCTIONS
When you switch on the unit the green LED (
Fig 8
Power indication
) should give out
continuous green light. If it does, your unit is powered on. If this is not the case,
check the connections again.
Fig. 8 Power indication
NOTE
Rapid, continuous blinking of the blue LED (
Fig. 10
Sensor calibration / Modbus
register reset / normal operation indication) indicates that the unit operates properly.
Check if the LEDs shown in
Fig. 9
Modbus communication indication
blink. If they do,
your unit has detected a Modbus network. If they do not blink, check the connections
again.

ATTENTION
The status of the LEDs can be checked only when the unit is energised. Take the
relevant safety measures!
