Seg WIC1 User Manual

System-(ERROR-)LED is Lit Constantly Red
Description Information Corrective Action
The WIC1 “Error” LED is constantly
red.
The (hardware-based) backup
protection is up and running,
but the WIC1 could not start as
normal due to a serious software
or hardware error.
The backup protection has become
active automatically, so that there
is at least some basic protection.
Nevertheless, the WIC1 needs to be
checked as soon as possible. Try a
restart, and/or contact SEG Support.
The DiggiMEC System LED is
constantly red. The DiggiMEC display
shows: “Level 0 – No communication
to WIC1”
This is only possible if the
DiggiMEC is supplied with
electricity via the USB interface
from a connected PC, but there is
no connection to the WIC1.
Check the connection between DiggiMEC
and WIC1.
Check whether the WIC1 is running in
the “Backup Protection” mode, see ╚═▷
⇱. (For information about the “Backup
Protection”, see ╚═▷ “4.13 Integrated
Backup Phase Overcurrent Protection”.)
Check whether the WIC1 is defective.
If everything turns out to be o.k. contact
the SEG Support.

Hardware
Description Information Corrective Action
Supply via Powerbank is not possible. The so-called powerbanks are
constructed with respect to
charging batteries, and many
of them cannot be used as a
permanent power supply.
It is possible to supply the WIC1 with
connected DiggiMEC by a PC, via the
USB interface. This way it is possible
to make settings without the supply via
the CTs. (But keep in mind that the USB
voltage of 5 Volt is not su󰊡cient for the
trip coil output or the 󰊠ag indicators /
output relays.)
But this kind of supply via USB is not
possible, if a powerbank is connected,
instead of a PC. This is due to the design
of a powerbank and cannot be solved by
any means related to the DiggiMEC or
WIC1!
There are powerbank models with a
key for power-on/wake-up/testing; these
models output the USB voltage only
after the key has been pressed.
Independent of this, many powerbank
models feature a device-internal
automatic switch-o󰊞. As soon as the
current 󰊠ow drops below a particular
value (typical 100 mA) the powerbank
switches the voltage o󰊞. The reason is
that the risk of overcharging a battery
shall be minimized. But since DiggiMEC
and WIC1 are designed for very low
power consumption they use much less
than 100 mA, and this fact makes such
types of powerbanks unusable as a
power supply of DiggiMEC und WIC1.
Wrong measuring and tripping
values.
Wrong wiring Verify that the wiring of the contacts
S1, S2 and of the test windings C, D is
