Transducer Connection Side Leds; Overflow / Underflow Indication - HBM espressoDAQ DQ401 Bedienungsanleitung

Meaning of the LEDs

8.3.2 Transducer connection side LEDs

The module run-up phase begins after the supply voltage is connected.
This is indicated by all the LEDs on the transducer side of the module succes-
sively lighting up.
Sequence:
1. All the red LEDs light up
2. All the orange LEDs light up at one-second intervals
3 One second later: all the green LEDs light up
The LEDs then indicate the current status at the transducer connection.
