6 Contact signal functions
6-1 Contact signal I/O details
The customer can automate processing in the event of a power outage by developing a
system on their own with contact signal inputs and outputs in accordance with the
following specifications. It is possible to perform processing for a power outage by
detecting a backup signal and perform system exit processing by detecting a low battery
level signal.
In addition, by inputting a backup stop signal from the system, it is possible to stop the
UPS while the battery still remains, and become ready for the next occurrence of power
outage.
With an optional contact I/O card, contact signal inputs and outputs can be used.
For details on how to handle optional cards, refer to "How to use optional cards" (P.70).
6-1-1 Types of signal outputs
The UPS has the following four types of signal outputs.
The output circuit consists of an open collector circuit using a photo coupler (a kind of
electronic switch).

failure.
Low Battery Level Signal
output (BL)

during backup operation.
Trouble Signal output (TR)
