Parameters
The parameters describe the Powerware 9170 system operation.
Some useful parameters are input and output voltage, input and
output current, and battery voltage. The UPS measures or records
many other parameters. Some are operatorĆadjustable, such as the
local date and time and various operating limits. All parameters are
password-protected. Although every operating condition and parameter
is accessible through the front panel display, you may change a value
only if you have entered the correct password to allow you to change it.
After making any parameter changes, delete the password level to
protect the UPS against unauthorized parameter changes. Press the Top
or ESC buttons to return to the Enter Password screen. Press the
button to view the default value (0000), and press the button again to
enter 0000, which invalidates the previous level.
NOTE After 10 minutes of inactivity, the UPS automatically deletes any active
password level and returns to the normal running display.
