FA ROTEX Solaris RPS4 - 06/2015
7 x Faults and malfunctions
If the system cannot be filled (status "F"), even though the solar
operating pump P
S
is actuated by the controller, the following
faults can be the cause:
1. Air drawn down when the system was running idle is in the
solar operating pump P
S
.
Ɣ Check that the solar operating pump P
S
is running. The
automatic vent must always be working! Check the
sealing cap and loosen it if necessary (do not remove).
2. Check the installation for leaks.
Ɣ Check the installation for leaks and rectify if necessary.
Follow instructions in chapter 5 "Start-up and decommis-
sioning"".
3. The start run time "Time P2" (chap. 6.4).
4. Check the installation for blockages.In the event of frost, ice
plugs can be formed in poorly routed connection lines.
5. Check valve position on storage tank connection elbow.
If there is nothing showing on the display, and the main switch in
the illuminated "On" position:
Ɣ Replace the control system (electronic fault).
If the main switch is not illuminated in the "On" position, there is
no power supply to the control unit.
Ɣ Check the plug connection of the mains plug and the mains
connection (fuse, switch).
If water vapour is coming out of the solar storage tank when the
sun impinges on it, the flow rate is too low.
Ɣ In this case, the system settings must be checked.
Special notes on electric sensors
Ɣ Assess the display on the Solaris R4 controller.
Ɣ Unhook the Solaris R4 controller housing and unplug the
relevant sensor and remove terminal if necessary.
Ɣ Examine the contact positions of the affected sensors, and
measure the resistance (or the DC voltage for flow temper-
ature and flow rate sensors) on the sensor end.
When the fault has been rectified, the system automatically re-
sumes normal operation and is in the operating mode.
The resistance or DC voltage values of the sensors are listed in
fig. 9-1 and in fig. 9-2. Internal faults in the controller electronics
that can be diagnosed are displayed in the display in accordance
with tab. 7-1 (status "G"). They also cause a safety switch-off of
the pumps. "Switching OFF" and "Switching ON again" after
waiting for 2 mins. either rectifies the fault or the controller needs
to be replaced.
Only original ROTEX replacement parts may be used.
