9.6 Configuration mode (last Decimal point flashes)
In the configuration mode you can set the value of a parameter. The display alternates between the parameter
relation and the currently set value until one of the Up/Down buttons is pressed, which changes the value of
the parameter. If no key is pressed for 2 s the display starts alternating again.
If no key is pressed for 30 s (simulation mode 15 min) one automatically returns to the display mode (the most
recently set value is applied during this)
Hint: Simultaneously pressing the Up and Down keys resets the adjustable value to zero. If the Up or Down
button is kept pressed while setting the value the change in the display is accelerated.
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 8test8 displayed.
At the end of the test the result 8pass8 (passed) or 8fail8 (not passed) is displayed for 30 seconds. Reset
stops the test.
During self-test supply- and measuring-voltage may not be disconnected!
9.8 Display Self-test result
The values and times have been measured during self-test can be displayed by pressing button Test shortly.
Kind of limit (8U:: 8 , 8U: 8 , 8Um 8 , 8U_ 8 , 8U__ 8 , 8f:: 8 , 8f: 8 , 8F_ 8, 8F__ 8 ), response time,
measured value, trigger value and adjusted limit are displayed. LEDs (yellow) at the terminals L1…N shows
the measured and trigger value.
By pressing Test shortly display changes to the values of the next kind of limit. At last the result 8pass8 (passed)
or 8fail8 (not passed) is displayed and additionally the switching time from K1 if 8trel8 is 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 8 is 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).
