Product description
3.1
Structure
The Digital Data Interface is a communication module with integrated web server that
has been integrated in the motor. It is accessed and controlled in an Internet browser
using a graphical user interface. The user interface enables easy pump configuration,
control and monitoring. Different sensors may have been installed in the pump for this
purpose. External signal transmitters may also input additional system parameters in
the control. The Digital Data Interface is capable of the following, depending on the
system mode:
ƒ
Pump monitoring.
ƒ
Controlling the pump with a frequency converter.
ƒ
Controlling the complete system with up to four pumps.
3.2
System modes
The Digital Data Interface can be licensed for three different system modes:
ƒ
DDI system mode
System mode with no control function. Only temperature and vibration sensor val-
ues are recorded, evaluated and saved. The pump and the frequency converter (if
present) are controlled via the operator’s primary control.
ƒ
LPI system mode
System mode with control function for frequency converters and clogging detec-
tion. The pump/frequency converter pairing works as a unit: the frequency converter
is controlled through the pump. This allows clogging detection to be carried out and,
if necessary, a cleaning process to be started. Level-dependent control of the pump
takes place via the operator’s primary control.
ƒ
LSI system mode
System mode for complete control of the pumping station with up to four pumps. In
this process, one pump operates as the master and all other pumps are slaves. The
master pump controls all other pumps depending on the system-specific paramet-
ers.
Licence keys enable system mode. System modes with less comprehensive functional
scopes are included.
