Application and function
The display unit DU-3 for the electronic remote indicator (EWLI-3) is for the remote display of the fill level measured by the EWLI-3.
The DU-3 receives its data via the CAN bus (system) via which the 24V supply (when using up to 3 DU-3s) is also possible.
The DU-3 displays the system status via 3 system LEDs. Further LEDs display the status of the probes.
Each probe of the recording module is displayed green or red in the LED illuminated display depending on status (water/steam). The number of the top currently submerged probe is displayed as fill level information in the 2x7 segment.
This also enables correct operation (fill level) to be identified at a greater distance.
Moreover error states can be rapidly and reliably diagnosed with the aid of the 2x7-segment display and 3 status LEDs.
As output there is a 4mA .. 20 mA signal for loads up to 500 Ohm available.
