* BS signal delay time
It is possible to set the period of time from when a BS signal is received until the output of the UPS is stopped. The output of the UPS can be
stopped by inputting the voltage signal (High).

Stays ON during backup operation at a power failure.
Goes ON when the battery becomes weak during backup operation at a power failure.
Goes ON when an internal failure of the UPS occurs or when the battery life counter expires.
Goes ON when the test determines that battery replacement is necessary due to deterioration
or when the battery life counter goes off-scale. (The battery life counter goes on counting during
the input power is being supplied.)
When the BS signal is ON (High), the output of the UPS is stopped after the time period specified
in advance has elapsed.*
Remote ON/OFF signals can be used to start and stop the UPS, by using either an externally
connected contact or the ON/OFF status of the open collector circuit. When signal is OFF, the
UPS will be turned on. When signal is ON, the UPS will be turned off.
In the factory settings, the UPS stops operation when this is short-circuited.
You must connect the unit to the input power supply to be able to use this function.
