Tank LED
The reserve tank has the task of storing the demineralized water necessary to
keep the generator running for a period of at least 3 days. The level of the liquid
inside this tank can be seen through the vertical window on the front of the ge-
nerator, a green backlighting LED enables distinguishing the level in the tank and
provides information on its status:
The LED is on steady when the tank has sufficient water to allow the generator
to operate;
the LED blinks when the water reaches the minimum level in the tank and you
need to fill it (
par. 4. Demineralized water and par. 11. Troubleshooting
)
;
the LED is off when the resistivity sensor is not connected.
