Additions to individual bullets of the settings menu
Adjustment of control settings
Start Delay
The pre-set start delay will only be active after a power outage. For all further activations the pumps
will start up right away once activated by the level.
Minimal level settings (On/Off)
If the start level is chosen to be smaller than 5 cm, the software will automatically use 5 cm as start
level. If a stop level is chosen to be smaller than 3 cm, the software will automatically use 3 cm as
stop level.. In addition, the start of the stop delay time will then begin at 3 cm. This is necessary in
order to safely operate the control unit.
Stop delay
Stop delay will make it possible to pump out below the level sensor (for example for impact
pressure systems)

Monitoring of operating time
The bullet “Operation limit” can be chosen in the menu. In the condition supplied at delivery, the
value is set to zero. This means the function is deactivated. If the value is set between 1 – 60
minutes the pump will be deactivated once it ran for longer than the pre-set time without
interruption. Additionally, an alarm will be triggered and an according fault report will appear on the
display. The pump will only proceed once the fault has been confirmed. The operation time
monitoring concerns the automatic mode and the manual mode.
Current limit (max. current)
The nominal current of the according pumps can be adjusted directly. The software of the control
unit will add a certain percentage to a set value in order to adjust tolerances.The activation will occur
according to a I² / t function and therefore considers the high starting current of the pump.For
pumps where the temperature control consists of a single bimetallic contact, the malfunction
“thermal fault 1” can be deactivated in the menu. “Thermal fault 2” cannot be deactivated in the
menu.
