8 Push-button for battery alarm
If the battery charge level drops below 10 %, the battery alarm will activate and give an audible warning. This warning
can be acknowledged by pressing the button on the right side of the instrument.
If the charge level drops under 3 % the alarm starts again and can’t be deactivated by pressing the button. In that case
there are 60 seconds left to change the battery or connect an external supply. If time is up, the output is deactivated
to protect the batteries from damage.
If the battery charge level reaches above 10 % (by charging or replacing the batteries), the charge monitoring is
reactivated and starts again when the charge level drops below 10 % .
9 ON-OFF push-button with integrated power LED
Press the button briefly: power on the output
Press the button 5 seconds: power off the output instantly
The system can be also switched off remotely. In this case the DW2-UPS waits until the power drops under a certain
limit for more than 1 minute before powering off the output. That allows the computer to reboot in case of a system
update. To reactivate the system press the button.
The button also shows the output state of the DW2-UPS:
- Green illuminated:
Output is on
- Not illuminated: Output is off
This is independent from the battery charger!
