Final answer:
The "WAIT" message on the PBIT screen appears for a few seconds after powering up the ELES system before the CDP displays the ELES STATUS menu.
Step-by-step explanation:
The display of "WAIT" on the PBIT (Power-On Built-In Test) depends on the specific system and its configuration, so the exact time can vary. However, in general, the "WAIT" message on the PBIT screen appears for a few seconds after powering up the Electrical Energy Storage (ELES) system before the CDP (Control Display Panel) displays the ELES STATUS menu.
The time that the 'WAIT' message is displayed on the PBIT after powering up the ELES before the CDP displays the ELES STATUS menu can vary depending on the specific system and its initialization procedures. Without specific information about the system in question, it is difficult to provide an exact duration. However, PBIT (Power-on Built-In Test) processes in complex electronic systems generally take a short period to complete their diagnostics before system status is available to the user. Once the PBIT is complete, the control display panel (CDP) would typically update to show the system status or ELES STATUS menu.
