Behaviour after power recovery

Behaviour after power recovery
After the device has been inserted to a socket or after
power recovery the pluggable switch and meter performs
a self-test/restart (approx. 2 seconds). The device LED
flashes orange and green briefly (LED test display). The
LED will flash if an error is detected during this test (see „8.4
Error codes and flashing sequences" on page 38). This is
repeated continuously and the device does not perform its
function. If the test is completed without errors, the plug-
gable switch and meter transmits a wireless telegram con-
taining its status information.

Troubleshooting
8.1
Command not confirmed
If at least one receiver does not confirm a command, the
device LED lights up red at the end of the failed trans-
mission process. The failed transmission may be caused
by radio interference (see „11 General information about
radio operation" on page 41). This may be caused be
the following:
•
Receiver cannot be reached
•
Receiver is unable to execute the command (load
failure, mechanical blockade, etc.)
•
Receiver is defective
