correct. Check the phase sequence and
phase angle.
Test winding short-circuited. Make sure that the secondary side of a
test winding is always – except when the
relays is tested – operated openly.
Grounding of a winding terminal of
the measuring winding.
No winding terminal of the measuring
winding must be grounded! Grounding
is done internally and connected
with terminal “PE”, see ╚═▷ “3.3.1
Grounding”.
Low-energy tripping coil does not
trip.
The coil polarized with permanent
magnet has been connected to
TC+ und TC− with the wrong
polarity.
Check the wiring.
Failure of a binary output (DiggiMEC). The physical status does not
match the reported state, as it is
being shown via Smart view.
Check the following issues:
• Is the binary output in latched•
state? (»BOx latching« = „With
latching“)?
•
Try to reset the output, e. g. via
•
the Direct Command [Operation /
Reset] »Rst. LEDs, FIs, Flt.Scr.«.
•
Check the wiring.
•
•

do not react.
• If all these checks do not yield any•
results, send the device back to the
manufacturer.
Failure of a binary input (WIC1). The physical status does not
match the reported state, as it is
being shown via Smart view.
Check the following issues:
• Check the typecode of the WIC1 –•
Does this device variant feature
congurable Digital Inputs?
•
Is the voltage level set correctly?
•
Check the setting at [Device
Para / WIC1 / Digital Inputs] »Nom
voltage«.
•
Is the voltage level of the digital
•
input (i. e. the signal level) correct?
• Check the wiring.•
• If all these checks do not yield any•
results, send the device back to the
manufacturer.
No system time is shown via Smart
view.
This is not an error, as the WIC1
does not feature a real-time clock.
All timestamps, as shown e. g. in the
Fault Recorder, refer to the device
uptime, i. e. this is the time since the
last reboot.
