8.1 Additional functions
Sleep-Modus
If the control unit has been working by battery for more than 2 hours, it goes into the so-called "Sleep mode".
This means that the operating valve flap is closed automatically. During sleep mode (flap closed), an optical
and acoustic alarm is given every 20 seconds until the battery is discharged. At the same time, the alarm is
displayed via the optional potential-free contact. In sleep mode, the control unit is in a "resting position". All
the displays are switched off. The fault message via the potential-free contact remains, however. Once mains
voltage is available again, the control unit returns to normal operation immediately. This function prevents the
battery from being discharged completely and then no longer being able to function in the event of a power
failure. This is particularly important during the construction phase, for example, when the control unit is
installed but not yet continuously supplied with mains current. In this case, the Pumpfix/Ecolift is ready for
operation thanks to battery operation, but the battery is not discharged complete
