Cause
The value of the power dissipation in the air-conditioning field <x> has changed. Therefore a new air-conditioning calculation is required for this air-conditioning field.
Note:
The comparison criterion for this check run is the power dissipation occurring in the respective air-conditioning field. The current power dissipation is compared with the power dissipation of the last air-conditioning calculation. This check can be carried out for a maximum of 100 air-conditioning fields.
Depending on the air-conditioning field that was selected all the power dissipations are added under consideration of the simultaneity factor for all the items of the air-conditioning field in accordance with the following formula:
Total power dissipation per air-conditioning field = Total (Power dissipation x Simultaneity factor) + Total (Busbars)
This calculated value is compared with the values of the project properties Thermal design: Total power dissipation for air-conditioning field [1] to Thermal design: Total power dissipation for air-conditioning field [100].
If the currently calculated value does not agree with the values stored in the project properties, the check run message is issued.
In addition the check run message is issued when a total power dissipation is issued for a air-conditioning field that does not exist / no longer exists in the project properties.
Solution
- Note the number of the air-conditioning field that was output in the message.
- Select the menu item Utilities > Reports > Calculate total power dissipation.
- Activate the Display all the air-conditioning fields existing in the project check box in the Calculate power dissipation dialog.
- Activate the corresponding check box of the reported air-conditioning field and start the calculation with [OK].
- Also check in the project properties whether an air-conditioning field is entered that does not exist / no longer exists at the enclosure and delete this entry.
- Then start a new check run.
