Test functions
Code
Description Remarks Remedy
124 Voltage adjusting
command has no effect
The measured value for
dU/dt was less than
0.1 %/s
The message is also
displayed if
TEST U-Match is still set
to ON and another test
function is to be carried
out Check whether:

adjusting commands are
effective (LED, relay contacts,
ext. circuits to voltage
regulator)

adjusting commands act in the
right direction

measuring voltages are
permanently present during the
test function
125 Frequency adjusting
command has no effect
The measured value for
df/dt was less than
0.05 %/s. The message
is also displayed if
TEST f-Match is still set
to ON and another test
function is to be carried
out
Check whether:

adjusting commands are
effective (LED, relay contacts,
external circuits to governor)

adjusting commands act in the
right direction

measuring voltages are
permanently present during the
test function
126 Possible range for ton
exceeded The measured value
must lie between 0 and
1 s. The message is
also displayed if
TEST ton is still set to
ON and another test
function is to be carried
out

Check whether the paralleling
commands are effective (LED,
relay contacts, ext. circuits to
circuit breaker)

Dual channel systems: The
series-connected second
channel must be bridged,
ideally by applying the release
dead bus signal

See section 4.2 for correct
handling of the test function
127 Test function is active One or more test
functions TEST ton,
TEST U-Match or
TEST f-Match of the
current parameter set
was still set to ON, while
trying to set the device
to READY. Set test function to OFF
and confirm (!)
& , then set device to
READY
128 Result of the test function
is not plausible The result calculated by
the test function lies
outside of the settable
range. This is
determined by the
maximum and minimum
value of the
corresponding
parameter See section 4.2
