3 Application and brief description
The SPI1021 monitors voltage and frequency in plants for own generation of electricity. It fulfills the
requirements of CEI 0-21 + DEWA.
6 selectable programs allow measuring, 3 phases to neutral (4-wire mode), 3 phases phase-phase (3-wire
mode) and single phase to neutral (2-wire).
The SPI1021 can monitor all decentralized power plants, photovoltaic, wind or thermal, that feed in the low or
medium voltage grid. In applications with possible asymmetry >6kVA, power balance has to be monitored
extra.
All limits are preset according to CEI 0-21(Pr1-3) or DEWA (Pr4-6). They can be changed if required and be
protected with a code and/or a seal.
A counter for alarms and standbys stores the last 100 events with reason and elapsed time. In addition the
time the SPI1021 has interrupted the plant is recorded. All values can be read displayed at the device and
give the operator valuable information about the availability of the plant.
The standby input allows a remote shutoff e.g. with a RCR. It can also be used to switch to an energy saving
mode by a timer or a twilight switch. Number of standbys and added time are stored and can be read in the
display.
4 Summary of the functions
When the device has been installed, a self-test starts automatically. The self-test can be repeated when
required. All values of the test are stored and can be read out at the display.
•Monitoring of under- and overvoltage 0/15-520 V
•Measuring of 3 phases with or without neutral or single phase
•Monitoring of over- and underfrequency 45-65 Hz (voltage dependent, adjustable)
•Monitoring of quality of voltage (10-minutes-average)
•Monitoring of vector-shift (connectible) and rocof (rate of change of frequency)
•Input IN2 for selection of frequency window
•Input In3 for selection of mode transitory or definitive
•Input Y0/Y1 for monitoring function of connected switch (automatic detection of nc/no)

8.2 functional characteristics
Functional characteristics
Explanation
VSR display value
The highest measured value is always displayed. The display value
is reset to 0 by deleting the max. Value and when resetting into the
go (good) state.
Delay Enable On time
Runs down when starting the unit and after opening the enable
input; during this time there is no evaluation of the vector shift
Reset time
When a reset time 8dof 8is running, it is always counted down in
the display (shortest one first)
Reset
Use the Reset key or interrupt the control voltage for > 2 s (comply
with reset delay)
Display mode 8Scn8
After the last measurement it switches into the scan mode; this is
indicated by the display8scn 8.
All measurements will now be displayed cyclically for the time set in
8dit8.
MIN / MAX values
All min and max values are saved zero-voltage maintained (non-
volatile).
Alarm counter
The unit saves max 100 alarms (cause, measurement value, at
operating time). The LEDs indicate the cause; the tripping value
that led to the alarm each stands in the 7-segment display.
Alternately the time difference, current operating time –tripping
operating time is displayed. (how long ago the alarm triggered)
Cumulative alarm time
8tal .8
The cumulative alarm time TAL indicates how long the relay was
switched off due to an alarm. It is recorded with a resolution of 1
minute and only when the control voltage is applied.
Query: In the display mode button to 8ac .8is displayed. 1x
button = Cumulative alarm time8tal .8
Standby mode
8vsr .88stby.8
If IN1 is closed (e.g., by ripple control receiver, timer, dimmer),
Relays K1 and K2 are switched off. The number and duration of the
shut-downs is recorded.
Query: In the display mode button to 8ac .8is displayed. 2x
button = Standby counter 8stby.81x button = Standby time
8stby.8
Automatic restart attempts
If there is an error by the feedback contacts 8err78, 2 restart
attempts are automatically performed in an interval of 10s.
False triggering by undervoltage trips (e.g. during a thunderstorm)
do not lead to permanent shut-down.
Frequency undervoltage
protection
8uonF8
if one of the measured voltages less than 8uonf8, the frequency
evaluation is interrupted until all voltages have exceeded 8uonf8.

9.7 Self-test execute
In programs 1, 3, 4 the SPI1021 has an automatic self-test as recommended in CEI 0-21 and DEWA.
K1 can pick up only after the self-test has been passed once.
Self-test starts automatically as soon as measuring voltage is connected for the first time to a new device and
when there is no alarm! Self-test also starts automatically when program has been changed to 1, 3, 4.
Self-test can be started manually by pressing button Test for ≥2 s.
During the Self-test is 8test8displayed.
At the end of the test the result 8pass8(passed) or 8fail8(not passed) is displayed for 30 seconds. Reset

or 8fail8(not passed) is displayed and additionally the switching time from K1 if 8trel8is activated.
Display automatically returns to normal mode 30 s after button Test has been pressed for the last time.
9.9 Alarm counter
The alarm counter 8ac 8is increased by 1 with every shut-down. Up to 100 shut-downs are counted. That
allows quick detection of how often the SPI1021 has shut down since the last delete of the alarm counter (see
cumulative alarm time).
Query the alarm counter:
•Change into the display mode
•Press the button several times until display 8acxx8

9.10 Cumulative alarm time (display in hours)
The cumulative alarm time 8tal 8indicates how long the relay was switched off due to an alarm. It is
recorded with a resolution of 1 minute and only when the control voltage is applied.
Query the cumulative alarm time:
•Change into the display mode
•Press the button several times until display 8acxx8
•Press the button 1x display 8tal 8/ 8x.xx8

•Keep the button pressed for 2s until display 8tal 8/ 80.008
9.11 Alarm Memory
Independent of the alarm counter, the SPI1021 stores the most recent 100 shut-down causes (cause,
measurement value, at operating time). Simulated alarms are also registered. The LEDs indicate the cause;
the tripping value that led to the alarm each stands in the 7-segment display. Alternative to that
the time is shown in hours which have passed since the last tripping (with applied control voltage).
These values remain saved even after the power has been turned off.
Query alarm memory:
•Change into the display mode
•Press the button several times display 8acxx8
•Press the button 1x display 8 x.xx8/ 8x.xx8
(tripping value or error no. / time that has passed in hours)
•Press the button 1x, go to next alarm
The alarm memory is only deleted during a program change.
9.12 Standby counter and standby time
The standby counter 8stby8, is increased by 1 with every standby shut-down. Up to 9999 shut-downs are
counted. That lets the SPI1021 quickly detect how often, e.g., shut-down was performed through a ripple
control receiver.
Query the standby counter:
•Change into the display mode
•Press the button several times until display 8acxx8
•Press the button 2x display 8stby8/ 8xxxx8
The standby time 8stby8indicates how long the relay was switched off by the standby mode. It is recorded
with a resolution of 1 minute and only when the control voltage is applied and if no alarm is present.
Query the standby time:
•Change into the display mode
•Press the button several times until display 8acxx8
•Press the button 3x display 8stby8/ 8x.xx8(Time LED is illuminated)

•Use the buttons to set the new, desired pin code (caution: write down the pin code)
•Press the button 1x
Code lock on, display 8on8flashes three times
Code lock off, display 8off 8flashes three times
Return to menu mode, menu item code lock
If there any problems with the code lock (Pin forgotten), the lock can be switched off and the pin can be reset
to 504 by keeping the Set key pressed while switching on the mains until 8Code8/ 8off8appears in the
display.
9.14 Sealing
All the settings and the simulation mode can be locked.
If the LED is illuminated, the SPI1021 is locked.
If an attempt is made to change a setting in the locked state, for 3s the display shows 8LOc 8.
Adjustment procedure Sealing/Lock ON (OFF):
•If present, remove seal (only authorized person)
•Apply control supply voltage at A1-A2
•Slightly lift the key cover and turn 180°
•Actuate the small blue button by pressing the button cover very firmly (LED starts flashing)
until the green LED is illuminated.

9.15 Simulation
Here, the voltage, frequency or a vector surge can be simulated and the setting can be tested. All 3 phases
plus the 10 minute mean value are always simulated. All functions of the device operate as if this value is
actually being measured. Alarm and error messages are only indicated with the LEDs and not in the display.
The set values are simulated until the menu item si . is exited with the or button. If the SPI1021 is
sealed/locked, simulation is not possible.
If the section switch feedback contacts are connected to the SPI1021 and enabled, (set value > section-
switch turn-on time under 8trel.8), after a shut-down, the tripping time (dAL + time of slowest section switch)
is displayed.
Adjustment process:
•Select the menu item with the buttons until display 8si .8
•Press the button 1x display 8si 8/ 8u 8
•Use the buttons to set the measurement factor for simulation:
o8u 8Voltage + 10min mean value (frequency = last simulated value)
o8f 8Frequency (voltage = last simulated value)
o8vsr 8Vector shift
•Press the button 1x display 82308(selected measurement factor is simulated)
•Use the buttons to set the desired value
After exiting the Simulation menu item with the buttons, the unit switches over to monitoring the limits.
The unit automatically returns to the display mode if no button is pressed for 15 minutes.
Hint: A limit value should be tested that is higher than the set 10min mean value. If the 10min mean value has
to be temporarily switched off, set (8Um .88off.8since otherwise it will trip first. The same applies, for
example, for U, , during a simulation of U,, .
