maintenance costs and efficient service assignments.
Example: Procedure for configuration using the LDSWin PC software
Specify alarm destinations
The refrigeration pack system should notify the service centre and the building control system should notify
the caretaker.
Specify the priorities and priority groups and assign them to the alarm destinations
Refrigeration pack system: Priorities 0..9Entire installation / building control systems: Priorities 10..99
Set the priorities in the components accordingly
The meaning of the priorities X1 and X2 in combination with the alarm relay must be observed, see chapter
: components / controller of the refrigeration pack system signal with the priorities 0..9
components of the building automation (heating, air conditioning,..) with the priorities 10..99
In order to illustrate the priority concept and the decades (priority groups), these are listed in the following table
and explained using examples:

the AUX relay is actuated

The settings must be planned and entered carefully. In the event of incorrect configuration, there is
potential for alarms to be sent to the wrong alarm destinations and not given the required attention
there.
