States of the LEDs
LED 1 (O.K./BAT.)
Signaling
LED 2 (BAT.> 85%)
Signaling
The LED and the relay contact (see Chapter Relay outputs (Page 44)) have two meanings:
1. If no additional settings have been made, then the previous LED signaling applies.
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.
