When allunits in the system are turned on, the system powers up as described below. Whenany unit in the multiple system is powered off, then powered on again, system powerup is again initialized as described below.The system powers up in four stages: initialization, identification, protection and power-up. Theentire 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 2-10)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 2-10). NOTE: Ifthe unit does not enter the identification stage, the unit must be turned off, removed from thesystem, and referred for service.During the identification stage, the master verifies that all the slaves are present, and are of theproper model, and are configured properly (series or parallel) for the configuration defined bythe master. At this time the power-up master module screen (Figure 2-10) should show the sta-tus of all slaves as either “Faulted” or “Not Used.” Other status indications must be correctedbefore the system can continue the power-up sequence:
