Configuration of suction optimization
Assuming a pack and evaporator suction group has already been
defined, go to the Pack controller configuration screen. Locate the
line ‘suction optimization’ and set to ‘yes’.
This automatically sets all evaporators associated with this suction
group to also operate in Po optimization mode. If required,
individual evaporator devices can be manually removed from the
optimization loop under the individual evaporator configuration
screens.
•
Set an appropriate Maximum float pressure (shown in 'k')
change that the optimization algorithm can make to the pack
controller.
•
Enter a post defrost delay (The time period that the Po
Optimization algorithm ignores the evaporator device after a
defrost. This allows the evaporator to recover from a defrost
without effecting the Po Optimization algorithm).
•
Define Po stop and alarm conditions (if x controllers enter off
line state, then stop optimization)
Once set, the Po optimization operation can be seen under the
pack controller screen (optimization tab)- refer to (local screen)
examples below.
If your AK-SM is configured for degrees C, Suction Optimization is “K”.
If set to degrees F Suction Optimization is “F”.
Enable suction optimization by selecting ‘Yes’. All evap
controllers associated with the Pack will then be tagged
‘yes’.
It is possible to remove any evap controller in the
optimization function by selecting ‘No’ in the (evap)
device detail (settings) screen.
