FA ROTEX Solaris - 08/2007
If steam escapes continuously from the Solaris Sanicube during solar radiation, the flow is too low.
• In this case, the system settings must be checked.
Special notes on electric sensors
• Evaluate the display of the Solaris R3 control unit.
• Open the housing of the Solaris control unit and disconnect the affected sensor.
• Examine the contact positions of the affected sensor and measure the resistance (or the DC signals for feed temperature and
flowrate) on the sensor end.
When the fault has been rectified, the system automatically resumes normal operation and is in the operating mode.
The resistance and voltage values of the sensors are shown in Fig. 8-1. Internal faults of the controller electronics that can be
diagnosed, are shown in the display according to Table 6-1 (Status G). They also cause a safety switch-off of the pumps.
Switching the system off and then on again after 2 minutes might remedy the internal fault; if not, the control unit must be
replaced.
WARNING!
An electric shock can cause severe burns and fatal injuries. Therefore, before opening the control unit housing,
the mains supply must be disconnected and secured against restart.
