Pump Replacement with Drive Running

During drive operation, one of the pumps must be running. Two pumps run
alternately switching from one pump to another after a preset time. This
switching time is dependent on the Control Program setup. A pump may be
replaced during drive operation by following the instruction sheet

the inside of the pump cabinet door.
