Commissioning

The control unit performs the following additional func-
tions automatically:
Sleep mode (rest position)
If the control is in battery mode for longer than 2 hours it
switches to so-called sleep mode. This means that the flap
of the backwater valve is closed automatically. During sleep
mode (flap is closed) an optical and acoustic alarm is emitted
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 rest position. However,
the error message persists via the potential-free contact. If
the mains voltage has been restored the control returns to
normal operation immediately. This function prevents the
batteries from being fully discharged, which would prevent
them from functioning in the event of a power failure. For
example, if the control is installed during the construction
phase but a continuous mains supply is not yet available. In
this case, the battery would quickly become fully empty.
Checking the battery voltage
The control unit checks the battery voltage 2x daily and sig-
nals a battery error (potential-free contact "fault") if the volt-
age falls below a certain level. Optical and acoustic warning
signals appear on the control unit every 20 seconds.
SDS self-check
016-003
The control unit has an automatic self-check, which performs
a functional check of the connected movable components
automatically. Even if no backwater events occur, the sys-
tem's readiness is checked.
