Initial Startup Preparation
Ensure that the Standby/Operate switch on each Rectifier is placed to the "standby"
position.
Ensure that all blocks for Chapters 2 through 4 in the "Installation Acceptance Checklist",
located in Chapter 1, have been checked.
Ensure all distribution fuses are removed, and all distribution circuit breakers are in the
off position.
LMS Initial Startup Preparation
This procedure requires a terminal to be connected to the system, either locally (Local
Port) or remotely (via the Modem Port). Refer to the separate LMS Installation
Instructions (Section 5879) for a procedure. Section 5879 can be accessed from the CD
(Electronic Documentation Package) furnished with your system.
If the local port is used, the terminal's communications parameters must be initially set for
19200 bits/s, 8 data bits, 1 stop bit, and no parity.
If the modem port is used, the terminal's communications parameters must be initially set
for 8 data bits, 1 stop bit, and no parity.
Initially Starting the System
Apply DC input power to the system by closing the external DC disconnect(s) or
protective device(s) that supplies battery power to the system.
Apply AC input power to the system by closing the external AC disconnect(s) or
protective device(s) that supplies power to the Bay(s). There may be one or more AC
disconnects or protective devices that supply power to each Bay.
If the system is equipped with a PDSC (AC Input Power Distribution Service Cabinet),
place the PDSC circuit breakers to the I "on" position.
On each Rectifier, place the Standby/Operate switch to the I "operate" position.
Place each distribution circuit breaker (if furnished) to the ON position and install all
distribution fuses.
MCA Initialization
Whenever a system is initially started (or the MCA has been replaced), the MCA
performs an initialization routine. This routine is described below.
The MCA is located in the Primary Power/Distribution or Power Only Bay.
Initialization Routine
1) When power is initially applied to the system, the MCA briefly displays the MCA
Software Version Number and then establishes communications with each
Rectifier.
2) The MCA then displays CHECK VALUES BEFORE STARTING.
As you press the FUNCTION SELECT UP and DOWN arrow keys, each value
listed in Table 5-2 is displayed. To change the setting of the currently displayed
entry, press and release the ALARM CUTOFF and FUNCTION SET ENTER
keys simultaneously. Line 2 of the display is replaced by "CHANGE THE
VARIABLE". Use the FUNCTION SET YES (+) or NO (-) key to increase or
decrease, respectively, the setting. Press the FUNCTION SET ENTER key. At
the "ARE YOU SURE?" prompt, press the FUNCTION SET YES (+) key to store
