8.2 Testing the fans
You can verify the operation of the fans in two ways:
• Set the parameter „Fan Test“ to „1“ (with Sunny Data, Sunny Data Control or
with the data logger Sunny Mini Central Control).
• Use the jumper on the control board of the Sunny Mini Central (see figure below).
For setting the jumper for the fan test, proceed as follows. Stick to the order specified
below!
1. Open the Sunny Mini Central 5000/6000 as described in chapter 6.1 „Open-
ing the Sunny Mini Central” (page 35).
2. Put the jumper in the slot shown in the picture below. The jumper is included in
delivery
3. Close the Sunny Mini Central as described in chapter 6.2 „Closing the Sunny
Mini Central” (page 35) and switch it on again.
4. The Sunny Mini Central can not detect the jumper, until you deactivate and re-
activate it.
After setting the jumper, switch on the Sunny Mini Central. Check the air flow of the
fans. The Sunny Mini Central aspirates the air from the bottom side and blows it out
on the sides of the device. Pay attention to strange sounds, they might be a hint for
an incorrect installation or a defective fan.
When you finished testing the fans you have to reset the parameter „Fan-Test“ to „0“,
or you have to remove the jumper.
