System Mode Selection
The control system comprises three different system modes: "DDI", "LPI" and "LSI". Po-
tentially available system modes are enabled using the licence key. System modes are
downward-compatible.
ƒ
System Mode Selection
Factory setting: depends on licence
Input: DDI, LPI, LSI
Description of the individual 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.
6.5.5.4
LPI Control Settings
Basic settings for "LPI" system mode.
ƒ
Control Source
Setpoint specification from the primary control.
Factory setting: Analog
Input: Analog, Bus, Fix frequency
–
Analog
Primary control values are transmitted to the frequency converter or an I/O mod-
ule as analogue signals.
NOTICE! Configure an analogue input using the "Set-
point" value!
–
Bus
Primary control values are sent to the pump using the Ethernet network. Mod-
Bus TCP or OPC UA are used as communication protocols.
–
Fix frequency
The pump runs at a fixed frequency.
ƒ
Fix Frequency Value
In the "Control Source" setting, select the "Fix frequency" value enter the corre-
sponding frequency.
Factory setting: 0 Hz
Input: 25 Hz to max. frequency (f
op
) according to the rating plate
