Control elements of the ScrubberGuard on the cabinet
The ScrubberGuard is controlled via four control elements located on the cabinet. These are
three buttons plus a control input for external actuation. Only one control element may be
active at any one time. Activation is confirmed by the respective button lighting up. If multi-
ple functions are activated, this leads to a fault that is signaled by the flashing buttons. To
rectify this problem, all functions must be deactivated.
In order to ensure correct operation, the AquaScat SG (A) must be connected and the com-
munication between the AquaScat SG (A) and cabinet must be established.
