The LED and the relay contact (see Chapter Relay outputs (Page 34)) have two meanings:
1. If no other settings have been made, then the LED lights up after reaching a charge state
greater than 85 %. The LED goes dark if the charge state falls below 85 %.
2. If an expected buffer current and a buffer time are set under the hardware configuration,
then the LEDs and the relay contact serve as an indicator when buffering is possible with
the two parameters – or is no longer possible.
Note
From the instant in time when the SITOP UPS1600 is switched over into the buffer mode, for
the evaluation, instead of the expected buffer current, the actually measured buffer current is
used. As a consequence, the status of the LEDs and the relay can also change.
