Status indicators
Three LEDs which indicate the status of the device are
installed outside the terminal box and observable by the
external side (Fig.2/D).
Green LED (pulsating):
Yellow LED (pulsating): Regenerating tank ON
Red LED (pulsating):
The display inside the box (Fig.2/A) shows information
about the time between 2 regeneration process.
To set this time is necessary to push the button (Fig. 2/B)
for 5 seconds until the number start to blink, after that,
pushing the button is possible to increase the number of
day (1 days steps, minimum value 1 days and maximum
value 50 days)
After 5 second where the button is not pushed, the
condition pass to idle.
The time between 2 regenerations cycles could be set in
accordance with the table in appendix A (as default it is fixed at 20
days for eSDB-14C / 30 days for eSDB-10C/12C)
What is detected
- Failure of the power supply
- Failure of the electronic circuit
- Failure of the heating element
- Failure of Solenoid Valve
