Frequency
Undervoltage
8UonF8
frequency undervoltage, below this value
the frequency protection is inhibited
8 0.08 … 8320 8
Hysteresis
8H 8
253V (Limit) – 3V (Hysteresis) =
250V (Reset value)
If the limit value is offset in Pr1 or Pr2 at
8F, 8, the hysteresis also has to be
adapted.

8dAL 8
An alarm is suppressed for the set time

8 0.058 … 8120.08
Turn-on time
(delay Off)
8dOF 8
Reset is delayed for the set time, also
during voltage recovery, this time (seconds)
is always counted down in the display
8 08 … 8 9998
Enable time
(delay On)
8dEon8
There is no evaluation of the vector shift
during this time; starts with the application
of the control voltage and when opening the
Enable input
8 28 … 8 208
VSR
8 VSR8
81 Ph8: a vector surge on one phase leads
to an alarm
83 Ph8: a vector surge on all phases
simultaneously leads to an alarm

8 0.18 … 8 2.08
9.4 Display mode (last decimal point off)
In the display mode, the SPI1021 is in its normal state; here, depending on the program, the actual voltage,
the highest actual 10 minute mean value, the frequency or the vector surge is displayed. In addition, the alarm
signals (e.g. 8aL 8 , 8aL m8 ) and error codes (e.g. 8err98 ) are displayed.
Function button
Set / Reset
Press briefly: Switches the measurement, alarm counter
Press for > 2 s: Resets after locked alarm
(not possible if doF Reset delay is counting down)
Press for > 4 s: Displays the program, e.g. 8Pr 18
Press for > 10 s: Displays the software version, e.g. 80-038
Function key
Up / Down
Press briefly: Change into the menu mode,
Display alarm counter: Down = Query the memory
Up = Query the cumulative alarm time
Press for ≥ 2 s: Displays MAX and MIN measurements, additionally
pressing the Set key for ≥ 2 s deletes the saved values
