NOTICE!
The green “System/Ready” LED has the 󰊟xed (non-con󰊟gurable) meaning: “Ready to
Trip”.
This meaning is more strict than a simple “device is running”. Therefore it is possible (for
example if the WIC1 is solely supplied via DiggiMEC-USB) that the WIC1 is running, so
that you can con󰊟gure it and/or read out measuring values, but the “System/Ready” LED
is o󰈚 (e. g. because the 5 Volts of a USB interface are o.k. for the operation of the WIC1,
but do not su󰊡ce for the availability of a ~24 Volts trip pulse).
More details about the »System« LED(s) can be found in the table below, in ╚═▷ “6 Self-
Supervision” and in ╚═▷ “10 Troubleshooting”.

Device not ready (yet). This can also be the case if
the software has completely started, but the WIC1
has not (yet) collected enough electrical energy for a
trip pulse.
Or: The phase currents are not su󰊡cient for the WIC1
so that it is still switched o󰊞.
Or: The device has been restarted into the “Service
Mode” operating mode. In this mode, it is possible to
reset all settings to the factory defaults, or to install a
󰊟rmware update.

Green LED: as above i. e. the WIC1 has collected
enough electrical energy for a trip pulse.
Blinking red color: The WIC1 has done an automatic
restart (due to a device-internal error) and entered
a “Protection-Only” operating mode. In this mode,
only the protection and supervision functions have
been started. (This might hopefully reduce the risk of
another error.)

In particular, all communication functions are

inactive, including connections with DiggiMEC
and Smart view.
• The DiggiMEC 󰊠ag indicators / output relays,•
however, should be functional.
• Although the protection functionality is fully•
active it is recommended to check (and/or
replace) the WIC1.

A serious error has been detected, so that the WIC1
