The regulator is fully open in dry weather. If the water level exceeds a certain height in rainy weather, the regulator is activated. The electric drive is actuated and closes the regulator until the slide plate position belonging to the accumulation height has been reached. The electronic controller constantly compares the measured stowage height with the setpoint. The control process continues until the backflow in the containment room has been removed and the backwater height is below the set limit. If this is the case, the control slide opens automatically so that the full drainage cross-section is available.
If a blockage occurs during the control process, this inevitably reduces the flow rate. This in turn leads to an automatic raising of the slide plate – if necessary – until the control slide is fully opened. After the throttle cross-section is flushed out and the flow rate increases spontaneously, the control slide moves back into its control position. In the case of backwater from underwater, the water level difference is recalculated and the target discharge volume is adjusted.
