FA ROTEX Solaris RPS4 - 06/2015
6 x Control
6.3.1 Display during start-up
After switching on, the Solaris R4 controller performs a self-test
where the display elements are actuated in a targeted manner
and the setting parameters of the user level are displayed. The
following testing steps are carried out, and the results displayed
for about 2 seconds (fig. 6-5):
– Immediately after switching on, the start display appears
which shows the installed software version and the serial
number of the device.
– During initial commissioning, the desired display language is
queried.
– After this, the current parameter settings which the user can
change are displayed.
– When the operating display appears, the self test is complete.
– The functions of the solar operating pump P
S
and their oper-
ating status lights can only be tested manually, for safety rea-
sons (see section 6.2.6).
