Checking The Fans - SMA SUNNY BOY 8000TL-US Installation Manual

Maintenance
9.2.1 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 jumpers on the system control board (the jumpers required to check the fans is
included in the Sunny Boy accessories kit).
Setting the parameter
1. Request the installer password on the SMA Serviceline (contact: see Page 71).
2. Set the "Fan Test" parameter to "1" in the installer mode.
3. Check the fans air-flow.
The Sunny Boy 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".
