Omron BU1002SW, BU3002SW Jumper settings, Output delay time setting for backup signal output BU

7．Using the UPS monitoring software and contact signal

●Output delay time setting for backup signal output (BU)

Continues during a power failure, and turns ON (OFF). By setting the contact signal card’s setting switch as shown in the table on the right, the length of time from when the power failure occurs until the power failure signal is output can be delayed between 0 and 3 minutes.

The power failure signal is not output if the power supply error is resolved within the set delay time.

●BU/BL signal reverse output setting

BU and BL signals are output in reverse.
