▼Chapter 3The intelligent reduction of power peaksPriorityEach shutdown level can be given priority between 0 and 32. Emax outputs with a priority of 0 are not included inthe trend value calculation undertaken by the Emax program. Emax outputs with a low priority (e.g. 1) are shutdown first and are last to be switched on again.Connection loadIn order to be able to determine the time of shut down more accurately, the nominal load power of the connectedload must be programmed for each Emax output. The switching times allocated to each Emax output are compliedwith on priority.Minimum connection timeThis determines how long a load must remain switched on between two switching actions.Minimum disconnection timeThis determines how long a load must remain switched off after shutdown.▼Maximum disconnection timeThis determines how long a load may remain switched off after shutdown.AvailabilityThe availability of a load can be set as a percentage value.Illustration: Emax programming using GridVis software103
