300 Parameters

The UPS uses some of its parameters to keep track of information, operating conditions, and power conditions. Other
parameters allow you to program some of the unit's features. This section explains how to display and change some
UNITY/I parameters.

301 Displaying Parameters

This section explains how to display parameters using the front panel keys and four-digit display. The table in
Section 303 contains more information about what many of the parameters mean.
Note: When the unit is in parameter mode, the front panel keys have different functions. See the label inside the
UPS front door for an explanation of the key functions in parameter mode. The label also shows a
"Programming Template" with different key names for parameter mode.
1. To enter the parameter mode, hold down the [
keys when the four-digit display changes to P-00. P-00 is a parameter number. The first column of the
parameter table in Section 303 contains the parameter numbers.
2. Whenever a parameter number (P-XX) is displayed, you can use the following keys to go to the parameter that
you wish to display:
• Press [%

5. If you wish to display additional parameters, repeat steps 2-4.
6. To escape parameter mode, press [VLINE] twice.

302 Changing Parameter Values

You can set some of the parameter values to program certain UPS features. The table in Section 303 describes many
of the parameters.
Make sure that you FULLY understand a parameter before you try to change the value. If you set certain
parameters improperly, the UPS may not operate correctly.
