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.
If the test magnet is held against the marking for longer than 30 s, the red LED will flash: the
device returns automatically to the current switch status.
The test magnet is not included in the scope of delivery. It can optionally be ordered as
an accessory. See the "Accessories" -> "Additional accessories" section
