*BPS/

 *UALM

6

Hardware abnormality signal

When this signal becomes valid, the PRIMEQUEST notifies the system administrator of

a CVCF abnormal condition.

When the *ACOFF signal goes ON with the *BPS signal already ON, the system judges

that battery-supported operation cannot be executed by the CVCF. In this case, forcible

system stop is executed instead of shutdown processing. Stopping operation in this manner

may cause damage to the system or data.

The signal becomes valid when this line and GND (pin 5) are short-circuited.

*BTL

7

Near-end-of-battery-discharge notification signal

The signal on this line notifies the PRIMEQUEST of the approaching end of discharge of

the CVCF battery.

This signal is used to notify the PRIMEQUEST that the power supply will shortly be

stopped because of battery power depletion, when power is being supplied from the CVCF

due to a power failure.

When the signal goes ON, the system judges that battery-supported operation cannot be

executed any longer. In this case, forcible system stop is executed instead of shutdown

processing. Stopping operation in this manner may cause damage to the system or data.

The signal becomes valid when this line and GND (pin 5) are short-circuited.

*ACOFF

9

Power failure detection signal

The signal on this line notifies the PRIMEQUEST that the CVCF has detected a power

failure.

When the signal becomes valid, the PRIMEQUEST performs automatic shutdown

processing.
