FeaturesSmart logic control (SLC) is a sequence of user-definedactions (see parameter 13-52 SL Controller Action [x])executed by the SLC when the associated user-definedevent (see parameter 13-51 SL Controller Event [x]) isevaluated as true by the SLC. Events and actions are eachnumbered and linked together in pairs. This means thatwhen [0] event is fulfilled (attains the value true), [0] actionis executed. After this, the conditions of [1] event areevaluated and if evaluated true, [1] action is executed andso on. Only 1 event is evaluated at any time. If an event isevaluated as false, nothing happens (in the SLC) during thecurrent scan interval and no other events are evaluated.This means that when the SLC starts, it evaluates [0] event(and only [0] event) at each scan interval. Only when [0]event is evaluated true, the SLC executes [0] action andstarts evaluating [1] event. It is possible to program from 1to 20 events and actions.When the last event/action has been executed, thesequence starts over again from [0] event/[0] action.Illustration 3.35 shows an example with 3 events/actions.130BA062.14State 113-51.013-52.0 State 213-51.113-52.1Startevent P13-01State 313-51.213-52.2State 413-51.313-52.3Stopevent P13-02Stopevent P13-02Stopevent P13-02Illustration 3.35 Example with 3 Events/ActionsStarting and stopping the SLCStart and stop the SLC by selecting [1] On or [0] Off inparameter 13-00 SL Controller Mode. The SLC always startsin state 0 (where it evaluates [0] event). The SLC startswhen the start event (defined in parameter 13-01 StartEvent) is evaluated as true (provided that [1] On is selectedin parameter 13-00 SL Controller Mode). The SLC stops whenthe stop event (parameter 13-02 Stop Event) is true.Parameter 13-03 Reset SLC resets all SLC parameters andstarts programming from scratch.3.11.2 13-0* SLC SettingsUse the SLC settings to activate, deactivate, and reset thesmart logic control sequence. The logic functions andcomparators are always running in the background, whichopens for separate control of digital inputs and outputs.Parameter Description VLT® Refrigeration Drive FC 10394 Danfoss A/S © 05/2016 All rights reserved.
