A
user-friendly interface box that maintains two-way communication with
the pump and monitors the operating conditions. Built-in diagnostics
indicate faults and dry-running, display operating status power
consumption and level switch input. The CU 200 control unit is a
combined status, control and communication unit especially developed for
the SQFlex system. The CU 200 incorporates cable entries for ...
power supply connection
pump connection
earth connection
level switch connection
Communication between the CU 200 and the pump
takes place via the pump power supply cable. This is called mains borne
signaling (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 by means of the on/off
button.
Inside the Box
The CU 200 control unit offers:
System monitoring
Alarm indication.
The following indications allow the operation
of the pump to be monitored:
Water reservoir is full (level switch)
Pump is running
Input power
The CU 200 offers the following alarm
indications:
Dry running
Service needed in case of:
- no contact to pump
- over voltage
- over temperature
- overload.
In addition, the CU 200 shows the symbols of the
energy supply options
Developed for the SQFlex water supply systems,
the CU 200 SQFlex control unit offers:
SQFlex Control Box. This controller and system monitor can be used
with solar alone or in combination with the IO101 (for manual generator
backup) and/or the IO102 ( for wind generator ). The CU200 will allow
you to add a float switch to shut off the pump when the storage tank is
full. The system monitor display on the CU200 shows the following: •
Pump operation • Full Tank • Input Power ( Watts ) • Alarm Indicator for
dry running, over voltage, overload and over temperature.
