Setting the switch points
Emergency impoundment volume
Switch volume 2
Switch volume 1
Residual volume
Blocking peak load operation
In order to use the pumps exclusively in alternating operation, the switching point for the peak load operation is
set to zero. The message "On peak load is disabled" appears in the display.
Negligible level settings (on/off)
If a switching point below 5 cm is selected, the software automatically uses 5 cm as the switching point. If a
tripping point below 3 cm is selected, the software automatically uses 3 cm as the tripping point. The same
applies to the start of the overrun time, which then starts from 3 cm. This is necessary for safe operation of the
switchgear.
Runtime change
A maximum runtime for the basic load pump can be set. At the end of the runtime, the system changes to the
other pump. The requirement for this is that both pumps are in automatic mode. After the third change with no
interruption, the alarm is also triggered and the message "Runtime alarm" appears in the display.
Runtime monitoring
NEW!
The Maximum Runtime item can be called up from the menu. The value is set to zero on delivery, i.e. the
function is disabled. If a value of 1 – 60 minutes is set, the pump is switched off if the pump runs uninterrupted
for longer than the set value. An alarm is also triggered and a corresponding error message is shown in the
display.
The pump does not start running again until the fault has been acknowledged. The runtime monitoring covers
automatic and manual mode.
Runtime change + runtime monitoring
It is advisable to only activate one of the two functions. If a time is set for both functions, only the function with
the shorter time setting is executed.
