Function test with test magnet

WARNING
L
Danger of injury!
‣
Ensure that no dangerous processes are triggered in the system.
Carry out a function test while the device is in operation.
‣
Hold the test magnet for at least 2 s against the marking on the housing.
 This inverts the current switch status, and the yellow LED changes state. When the
magnet is removed, the switching status valid at that time is adopted.
