b. From the Multiple Units menu, highlight Configuration (use ADJUST control or the Y
or U keys) and press ! to modify. Select Series, Parallel, Master 2X2 or Master
3X2, press $ to apply the change.
c. If Series or Parallel was selected in step b above, Connection Type shows
Series or Parallel as selected above. Highlight Unit Type and press ! to modify.
Highlight Master +1 , Master +2 , Master +3 , or Master +4 (Master +3 , or Mas-

2.8.4 POWERING UP SERIES/PARALLEL COMBINATIONS
After the units have been connected (see PAR. 2.8.1, 2.8.2 and 2.8.2), and configured (see
PAR. 2.8.3), turn on power to all units.
NOTE: There is no requirement for powering the units on or off in a particular order. When all
units in the system are turned on, the system powers up as described below. When
any unit in the multiple system is powered off, then powered on again, system power
up is again initialized as described below.
The system powers up in four stages: initialization, identification, protection and power-up. The
entire sequence takes less than 15 seconds to complete from the time the last unit is turned on.
a. Initialization. During the initialization stage, the power-up master unit screen (Figure 2-9)
should show the status of all slaves as “Faulted.” See Table 2-13 for an explanation of slave sta-
tus messages during power-up.
b. Identification. The identification stage is active when the message “Checking Slave Configu-
ration” is displayed at the bottom of the power-up master module screen (Figure 2-9). NOTE: If
the unit does not enter the identification stage, the unit must be turned off, removed from the
system, and referred for service.
During the identification stage, the master verifies that all the slaves are present, and are of the
proper model, and are configured properly (series or parallel) for the configuration defined by
the master. At this time the power-up master module screen (Figure 2-9) should show the status
of all slaves as either “Faulted” or “Not Used.” Other status indications must be corrected before
the system can continue the power-up sequence:
“No Answer” means the slave is not responding to requests from the master. Possible causes
are a) slave not powered up, b) bitbus cable not installed correctly or c) slave number incorrect.
“Mode Error” can be caused a) if the slave does not match voltage (for parallel) or current (for
series) of the master or b) the slave is not configured to series or parallel to match the configura-
tion expected by the master.
“Ready” A status of “Ready” is not valid at this stage. The master should automatically set the
unit to “Faulted.”
