Parameters
Table 4 shows the first 26 parameters. You can view or reset the
parameters using the control panel or a terminal or computer.
If you plan to view or change parameters from the control panel, see
“Using the Control Panel” on page 27 for instructions.
If you plan to view or change parameters from a terminal or computer
that you have connected to the RS-232 port, see “Entering Commands
from a Terminal or Computer” on page 44. When you use commands to
display or change parameters, identify the parameter with either its
number or name (see Table 4). If you use the name, you can enter the
entire parameter name or just the short form; you can also abbreviate
the parameter name as long as your abbreviation includes the letters in
the short form.
Although you do not need a password to view any of the first
26 parameters, all of them require a password to change (see the
password column in Table 4.) See “Entering Passwords” on page 28 or
“Entering Commands from a Terminal or Computer” on page 44 for
password information.
NOTE All changeable parameters except 0 (Time), 10 (Date), and 15 (Unit ID) are set
at the factory. Only qualified technicians using the proper metering equipment should
change other parameters. Improper calibration may cause the FERRUPS UPS to
malfunction. Call your service representative before you attempt to change any
parameters except 0, 10, and 15.
