4.2 Supplements to the individual items in the configuration menu
Configuring the switch points
Lock peak load mode
In order to use the popes exclusively in alternating mode, the switch-on point for peak load mode must be set
to zero. The display will show the message
"Peak load on is shut off" .
Lowest level configurations (on/off)
If a switch-on point is selected lower than 5 cm, then the software will automatically use 5 cm as the switch-on
point. If a switch-off point is selected lower than 3 cm, then the software will automatically use 3 cm as the
switch-off point. This also applies for starting overrun time, which will then start at 3 cm. This is necessary for
safe operation of the switchgear system.
Runtime change
A maximum runtime can be configured for the basic load pump. After that time has passed, there will be a
change to the other pump. This requires that both pumps be in automatic mode. After three changes without
interruption, the alarm is additionally triggered and the display will show the "
runtime alarm " report.
NEW!
Runtime monitoring
The menu can be used to access the item running time max. The default setting is for this value to be zero, i.e.
the function is deactivated. If a value of 1 - 60 minutes is set, then the pump will shut off after running longer
than the configured value without interruption. Moreover, an alarm will be triggered and a corresponding error
report will be shown on the display. The pump will not run again until the error has been confirmed. Runtime
monitoring applies to automatic and manual modes.
Runtime runtime monitoring
It makes sense to activate only one of the two functions. If a time is configured in the two functions, then only
the function with the lower time setting will be executed.
