1. Displays and push-buttons
(fig. 26)
The control is equipped with a display consisting of four light-emit-
ting diodes, an operation unit (two push-buttons) as well as an audi-
ble signal transmitter. The function of the light-emitting diodes and
push-buttons is explained in the following:
1.1 Green light-emitting diode:
Power status
The light-emitting diode indicates respective power status. In the
case of mains operation, the diode lights constantly. This is the nor-
mal condition. In the case of lapse of mains voltage, the control
automatically switches over to battery operation. This is signalled
by flashing of the diode.
1.2 Red upper light-emitting diode:
Backflow detection
Continuous lighting of the light-emitting diode signals backflow. If
there is no backflow, the light-emitting diode is off.
1.3 Yellow light-emitting diode:
Valve status
The light-emitting diode signals the valve status. If the diode lights
continuously, the valve is closed. A flashing light indicates that valve
is moving. Normally, however, this light-emitting diode is off.
1.4 Red lower light-emitting diode:
Fault diagnosis
If the ACO QUATRIX-K anti-flood protection system has a motor
fault, the diode indicates this condition by lighting continuously. In
case of battery fault, the diode is flashing.

1.5 System reset button
By pressing the push-button once, the audio alarm is cancelled in
case of a fault. By pressing the push-button twice, the system is
reset (the vave is opened and moves to initial position).
1.6 Test button
By pressing the push-button once, the valve is closed. Pressing
twice re-opens the valve.
1.7 Audible signal transmitter
The control is equipped with an audible signal transmitter. If the
valve is closed, an audible signal sounds (continuous tone). In the
case of faults (motor/battery), an intermittent tone sounds. By
pressing the system reset button once, the audible signal is swit-
ched off.
