Self-Supervision – Warning Messages
Description Information Corrective Action
SW 1 SSV Idx Over󰅱ow There have been so many Self-
Supervision messages (more than
65535) that the running number
underwent an over󰅱ow.
You might want to check all the listed
messages for the potential reason of this
excessive number of messages.
SW 2 Run Mode The displayed “Value” speci󰊟es whether
the WIC1 is running in normal mode
(Value = 1, full functionality) or in
protection-only mode (Value = 2).
After two device-internal errors within
a short time, the WIC1 enters
a protection-only mode. In this
mode, all communication functionality
(including connections to Smart view) is
unavailable.
(See also the signaling via LEDs,
╚═▷ “The »System« LED(s) – “Ready”,
“Error””.)
You can try to leave the protection-only
mode (and re-enter normal mode) by a
cold restart of the WIC1.
SW 3 V Superv. A problem with the internal power
supply of the WIC1 has been
detected. This may a󰅯ect the
capability of the device to operate
a trip coil and outputs.
A further safe operation of the WIC1 can
be assumed only if you check the WIC1,
proceeding as follows:
WIC1‑4 with external power:
• 1. ▷ Make sure the supplied voltage•
(and power) is su󰊡cient.
•
2. ▷ Restart the WIC1‑4, executing
•
the Direct Command [Service /
General] »System . User Restart«.
• 3. ▷ Wait for 5 minutes.•
• 4. ▷ Check whether this warning•
message has been issued again,
and check that the Ready/System
LED is lit in green color.
Self-powered WIC1:
•
1. ▷ Verify that there is no phase
•
current 󰊠ow (nor any supply via
USB), so that the WIC1 is o󰊞.
• 2. ▷ Feed in a phase current•
> 0.5 In
min
in all 3 phases.
•
3. ▷ Wait for 5 minutes.
•
•
4. ▷ (Re-)connect a DiggiMEC.
•
Check whether this warning
message has been issued again,
and check that the Ready/System
LED is lit in green color.
In addition to the checks mentioned
above (i. e. re-issue of the warning
message, Ready/System LED), you
should also check the outputs: Is it
possible that the assigned signals rattle
(e. g. a ground overcurrent pickup with a
low pickup threshold)?
It is also advisable to check the
connection cable between WIC1 and
234 WIC1 WIC1-1.0-EN-MAN
