UNIFI startup method repeats startup method priming - WKB98163

Article number: 98163

SYMPTOMS

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

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, ex:

 System status 2.png 

the system must pass through the standby state before going to the ready state. So startup to standby priming (method parameters) will be completed before startup to ready priming (method parameters). This is observed as the 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, then it is possible to observe 3 cycles of priming. 

FIX or WORKAROUND

Only program priming,etc in the startup to ready section of the startup method in the device management (do not program any priming for startup to standby).SU in UNI2.png
