various sensors for level measurement can be used: floating switches, dynamic pressure, air bubble
level measurement systems, external 4- 20mA- sensors. The respective sensors to be employed can
be selected via the control program. Then two pumps are directly activated by motor contactors.
The pump changeover can be effected via time-control or level-control.
Furthermore, the following devices for error messages are available: acoustic signaler, 4 relay
alarm contacts potential-free (programmable for: high-water, combined fault, pump on, malfunction
pump, unit okay), safety circuits in the form of a turn-on- and a turn-off-delay, motor current
monitoring systems, motor temperature monitoring systems and flood control sensors guarantee a
safe operation of the pump station.
The control system is operated via 9 short travel key switches, the program settings are displayed
on an LCD display. All settings are saved so that they are available when the control system is
restarted. The display language can be changed.
Besides the actual operational parameters, the control system also saves the controlling process
and the occurring malfunctions in a record which can be displayed on the LCD display.
