Checking The Fans - SMA SUNNY MINI CENTRAL 6000TL Installation Manual

SMA Solar Technology AG
8.1.2 Checking the Fans
There are two ways to check that the fan is functional:
• Set the "Fan Test" parameter to "1" in the installer mode
(using Sunny Data, Sunny Data Control, the Sunny Boy Control data logger, or Sunny
WebBox), or
• place the jumper on the system control board (the jumper required to check the fans is included
in the Sunny Mini Central accessories kit).
Setting the Parameter
1. Request the installer password on the SMA Serviceline (contact: see Page 62).
2. Set the "Fan Test" parameter to "1" in the installer mode.
3. Check the fansair-flow.'
The Sunny Mini Central sucks air in from underneath and then blows it back out on the upper
sides. Listen for any unusual noise, which could indicate incorrect installation or that the fans are
faulty.
4. After checking the fans, set the "Fan Test" parameter back to "0".
Setting the Jumper
The Sunny Mini Central recognizes the jumper only after the system has been restarted (i.e. all LEDs
must have gone out before a restart).
1. Open the Sunny Mini Central as described in section 7.1 „Opening the Sunny Mini Central"
(46).
2. Plug the provided jumper in the slot on the system control board as shown below.
3. Close the Sunny Mini Central as described in section 7.2 „Closing the Sunny Mini Central"
(48).
