Test function
Test mode is activated by pressing the "TEST" button. Test mode is indicated by the yellow
DEVICE LED. During test mode, the measured values continue to be updated but are not
output on the relevant channel.
Test mode is carried out as follows:
●
Pressing the "TEST" button switches to test mode.
●
When the "TEST" button is next pressed, output 1 is selected. This is indicated by
LED A01. The test output signal is output. With currents, voltages and power, this
corresponds to the full-scale value, in the case of cos φ
1
and frequency 55 Hz.
●
When the button is next pressed, output 2 is selected. This is indicated by LED A02. This
automatically deletes the value at output 1 and sets the value at output 2.
●
By repeating the previous step, all four outputs can be gradually tested with regard to
their wiring and correct scaling.
●
If output A04 is selected and the "TEST" button is pressed, all four LEDs are activated but
no output is set. When the button is next pressed, output 1 is selected again.
●
If the "TEST" button is not pressed for 30 seconds after selecting an output, test mode is
automatically canceled and normal operating mode is activated. The currently pending
values in the background are now available again at the outputs.

ZSI module
To be able to use the ZSI function on the SENTRON WL circuit breaker, the external
CubicleBUS ZSI module must be used.
