CU 200 SQFlex control unit
The CU 200 is a combined status, control and
communication unit especially developed for the
SQFlex system. The CU 200 also enables connection
of a level switch.
The CU 200 incorporates cable entries for
• power supply connection (pos. 6)
• pump connection (pos. 7)
• earth connection (pos. 8)
• level switch connection (pos. 9).
(The position numbers in brackets refer to fig. 24.)
Communication between the CU 200 and the pump
takes place via the pump power supply cable. This is
called mains borne signalling (or Power Line
Communication), and this principle means that no
extra cables between the CU 200 and the pump are
required.
It is possible to start, stop and reset the pump with
the on/off button (pos. 1). The CU 200 offers
• system monitoring
• alarm indication.
The following indications allow the operation of
the pump to be monitored:
• water reservoir is full (level switch) (pos. 2)
• pump is running (pos. 3)
• input power (pos. 11).
The CU 200 offers the following alarm indications:
• Dry running (pos. 10)
• Service needed (pos. 5) in case of
– no contact to pump
– overvoltage
– overtemperature
– overload.
In addition, the CU 200 shows the symbols of
the energy supply options (pos. 4).
