Kipp&Zonen SOLYS 2 Sun Tracker - Manual (Page 22)

indicates an error of the heater fan. The heater is built-in but only operates on AC power.
The Status LED gives information about the tracker operation. RED indicates starting up or hardware errors;
Orange shows the GPS information not present or lost. Green is the normal operating mode with GPS status.
The tables below show this information including combinations and blinking of the LED’s.

Table 5.1 Status LED
Normal start-up procedure after power on:
- Status LED blinking red during initialisation (time depends on tracker position)
- Status LED changing Red / Orange / Green until the 1 minute home position & full rotation lap is complete.
- Status LED changing Red / Orange / Green, three times to indicate initialisation complete
- Status LED Orange to indicate tracking without GPS (using previous GPS information)
- Status LED Green /Orange to indicate GPS position found but no time not (yet) stable
- Status LED Green to indicate GPS information complete (location, height, time and date)

Table 5.2 Power / Temperature LED
Input voltage can be 24 VDC or 90 – 264 VAC, if both are present AC power will be used. When running on
AC power and the internal temperature is below - 20ºC the tracker will not operate until - 20ºC is reached.
(Indicated by Power / Temp. LED) when running on DC power alone the tracker will try to start even under
-20ºC. When operating on DC power (heater not active) the interior will remain above - 20ºC for a long time,
even when environmental temperature gets lower. The internal dissipation extends therefore the
temperature range below - 20ºC.
Important: -Receiving GPS information can take up to 12 minutes.
-If all goes well, both the status- and power LED should be green.
