4)Apply ac Power. Turn on the circuit breakers that supply ac power to the rectifiers in the MX28B power plant. The main screen should appear on the control unit display (see Figure 4.6-1). The display on the control unit is a 2-lines by 16-characters display. The cursor cycles below the characters of the active selection on the display. Information shown in the second line of Figure 4.6-1 that extends beyond 16 characters (to the right of the “S” in “ALARMS”) can viewed on the control unit display by using the scrolling controls (refer to Section 4.6 for operation of the control unit).

NOTE: When ac power is initially applied, there is a 60-second period during which no alarms are reported.

WARNING: The power plant is supplied from a nominal 220Vac, 50/60 Hz source. Keep the ac input enclosure cover in place when the system is operational or energized

3.11.System Parameters Verification/Adjustment

The MX28B system control unit is delivered with pre-programmed parameter default settings. A complete listing and description of all system configuration parameters as well as displayable system status and information is provided in Section 4.6. Users should read Section 4.1 to gain an understanding of and how to use the operational features provided by the MX28B power plant. As a minimum, the following parameters should be verified and adjusted, if required, before connecting batteries or loads to the power plant:

1)Battery Float Voltage - default = +27.00Vdc (Check the manufacturer’s recommendation for the batteries being used in the system.)

2)Battery Maximum Recharge Rate - default = 12A.

3)System Voltage - measurement ≅ +27.00Vdc (This is a measurement by the system of the output bus voltage.)

4)LVD Option - default = “Enable” (If the MX28B does not have an LVD installed, this should be changed to “Disable”.)

5)Rectifier Information - Check the rectifier information displays to verify that all rectifiers installed can be viewed on the control unit display and that no rectifier alarms are active.

Section 4.6 provides location information for these parameters and how to make changes if required.
