BLACKOUT ALARM
An alarm can be set for a continuous blackout for a settable time in the "Blackout Alarm" section.
The alarm can also be enabled when power returns.
CAUTION!
•
Activating the power return alarm, both alarms will be generated each time the card is
turned on/off.
•
In the event of blackout, digital inputs stop working if not externally powered by a
backup circuit. Analog inputs and digital outputs, on the other hand, continue to work
until Z-GPRS2/Z-Logger turns off.
NOTE
•
In many situations it is convenient to receive a warning whenever the device turns on to
activate the power return alarm.

Alarm inhibition time
An inhibition time on the next alarm can be set. The alarm is ignored during inhibition time. This
time is reset after each alarm.
