Test mode without pumps:
To test the control system without the pumps, please note the following:
A) It is sufficient to connect PE, N and L1.
B) Terminal 32 / 33 and 39 / 40 must be bridged, otherwise the report
Therm. error 2 will appear.
C) In the configuration menu, the thermal errors for pump 1 and 2 must be turned off,
otherwise the error Therm. error 1 will appear on the display.
Options:
Operational 2nd pressure sensor:
Upon request, the PS2 system will come with an additional internal pressure sensor. This makes it possible to
have an affordable redundant monitoring system. A second dynamic pressure system is placed in the chamber
at a height not reached during normal operation. If the water level reaches transgress this cast socket and/or
the enclosed system by more than 8 cm, then an alarm is triggered and the pump is turned on. The system as
a fixed hysteresis of 3 cm. If an overrun time is activated, then the pump will additional run for the duration of
the overrun time configured. The additional pressure sensor is always active, irrespective of which system has
been selected for level detection (dynamic pressure, bubbler system, float switch or external 4 - 20 mA probe).
Float switch:
The inputs 11, 12 to 17, 18 can be configured for float switches. The display shows which switch is connected.
Closing contacts must always be used.
Terminals 11, 13, 15, 17 are internally connected such that it's also possible to work with one joint wire.
Attention !
In the configuration menu, set level - control = float switch.
Emergency control:
If the pumps are being run via a pneumatic system (internal sensor) or a 4 - 20 mA probe, then additional
emergency control will be possible via a float switch. The input for the high water alarm (23 / 24) is always
active, regardless of the system selected for level detection. If terminal 11 / 12 is closed, then it will trigger the
high water alarm and both pumps are turned on.
Attention!! In sewage applications, regulations regarding ex-zones must be met.
