Operation Manual SUPREMA
4. Operation of the System
• Brief description of the event
• Additionally, system events are logged (e.g. BUS failures or similar) for service
purposes. They serve as a source of information for the MSA service staff.
Configuration Changes History
This history stores changes of input parameter settings.
Each entry includes the following data:
• Date/Time of accepting and closing the calibration menu
• Measurement point number
• Name of the parameter changed
• New value of the parameter changed
Supply voltage history
This history stores over-limit and under-limit power supply events (internal power, external power,
battery backup). An entry is made every time a new maximum or minimum power value is
measured.
Each entry includes the following data:
• Date/Time of the power measurement
• Name of the power type
• Measured voltage value
Processor temperature history
This history stores over-limit and under-limit temperature events for the MDA-module processor.
When the temperature goes above or below the permitted range, the current temperature value
is stored, and when it returns to within the permitted range, the peak value from the deviation is
stored.
Each entry includes the following data:
• Date/Time of the over-limit or under-limit event
• Serial number of the MDA-module
• Temperature value
• Information on whether it remained out of the permitted range
or returned to it
Measure Data
This menu shows all measure points and modules. Therefore, the module is divided into the
“Measure Point” and “Module” submenus.
“Modules” submenu
From the “Module” submenu, the user can recall information on the system modules.
