WARNING
L
Risk of injury!
‣
Ensure that no uncontrolled processes are activated in the system.
Carry out a function test while the device is in operation.
‣
Hold the test magnet against the marking on the housing for at least 2 seconds.
 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 seconds, the red LED will
flash: The device returns automatically to the current switch status.
