UNIFI startup method repeats startup method priming - WKB98163

SYMPTOMS

• Startup method is enabled in device management
• Startup is initialized from either  
  • the console 
  • or the side panel when the system is in maintenance or error state

ENVIRONMENT

• UNIFI 1.9.9
• UNIFI 1.9.4
• UNIFI 1.8.2

CAUSE

When selecting startup to ready and the system startup status is in an error or maintenance state,

the system must pass through the standby state before going to the ready state. So startup to standby priming (method parameters) is completed before startup to ready priming (method parameters). This is perceived as priming repeating itself. 

In the case of running startup from the console, this should not be done when the startup method in device management is enabled because it will run both startup programs if the instrument startup status is not already in a ready state. Depending on the startup state, if startup is initiated from the console and there is priming programmed in the startup to standby and the startup to ready sections of the startup method, it is possible to observe three cycles of priming. 

FIX or WORKAROUND

Only program priming in the startup to ready section of the startup method in device management; do not program any priming for startup to standby.
