OAD LEVEL AND REDUNDANCY SYSTEM STATUS
HIMOD HP display represent in the home page a graphic bar showing the load level and the system redundancy
Load level:
The bar is a comprehensive representation of the number of PM set including their status in function of load level,
and operative conditions, as below shown:
PM configured and necessary to
supply the load
PM configured but not necessary
to supply the load
PM configured but not available
to supply the load
NOTE:
Every full colored box in the bar represent the system load level with 42 kW step.
Whenever the installation includes one or more power cabinet in parallel the bar show the system load level and not the single
cabinet load level.
Redundancy:
To increase the system reliability customer can add a number of additional PM (redundant PM) rather than just fit
those strictly necessary to supply the load.
All PM, including the redundant units operate together sharing the load.
Thanks to this reliable feature, we warmly recommend to set one or more redundant PM according with the power needed and
the installation type.
With a power cabinet full equipped (seven PM) at least one unit should be set as redundant unit.
Below are portrayed the possible bar status (six PM operating in the examples) according with the system conditions in function
of load level, redundancy and PM availability.
1-case: Normal operation (blue color)
Configured PM number
Redundant PM number
Number of operating PM necessary to supply
the load according to real load level
2-Case: Redundancy level reduction (Orange color)
3-Case: Redundancy level reduction due to PM
unavailability (Orange color)
4-Case: Redundancy lost due to load rate (Red
color)
5-Case: Redundancy lost due to complete
redundant PM unavailability (Red color)
