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 operator￿adjustable, 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.
