Line Conditioning Set Up
This option allows user to change various detection and warning levels for input AC voltages,
qualified and unqualified values, and transfer and retransfer set points for going in and out of
BATTERY, BOOST, and BUCK modes.
The MP2000E comes programmed with default values for these parameters that are consistent
with those specified by major Departments of Transportation. See Figure 6-33 for a
description of each parameter.
Note: Improperly set parameter values can cause permanent damage to the
unit. Changes should only be made by Myers Emergency Power Systems
trained personnel.
Contact Myers Emergency Power Systems Technical Support at 610-868-5400
before making any adjustment.

1. In the MAIN menu, select 4.
2. “Enter Password” appears (the factory set password is 1111). Type the password and
press ENTER. If the screen displays “Error in entering data… please try again,” the
password has been entered incorrectly. Enter the correct password, then press ENTER.
3. The Parameter Change Screen appears (Figure 6-32). Type in a new value that is within
the range of acceptable parameter limits and press ENTER.
4. The screen returns to the Line Conditioning Screen.
