Demand Control Chapter 12
Demand Control Configuration
Prior to configuring the loads in the controller, you must assign priority levels and interlock times to the loads in your
application. The configuration for the Efficient Industries Plant 1 Example is shown below:
Priority Levels
• There are up to 16 priority levels available.
• Loads with the largest priority number are shed first (priority level 1 is shed last).
• More than one load may be assigned to a given priority level. If loads share the same priority level, they will be shed
based on the time since the load was last shed. (In other words, when a shed is required, the running load with the
largest priority level number and the longest minutes since shed will be the next load to shed.)
Interlocks
• On Delay interlock is the minimum time the load must be off, in seconds, before it can be restarted.
• Off Delay interlock is the minimum time the load must be on, in seconds, before it can be shed.
• Max Off Time interlock is the maximum amount of time, in seconds, that the load is allowed to be shed per hour.
Configure the individual loads and the demand control schedule.
