This is an arrayparameter containing comparatorvalues 0 to 5.3.13.4 13-2* TimersUse the result (TRUE or FALSE) from timers directly todefine an event (see parameter 13-51 SL Controller Event), oras boolean input in a logic rule (see parameter 13-40 LogicRule Boolean 1, parameter 13-42 Logic Rule Boolean 2, orparameter 13-44 Logic Rule Boolean 3). A timer is only FALSEwhen started by an action (for example [29] Start timer 1)until the timer value entered in this parameter has elapsed.Then it becomes TRUE again.All parameters in this parameter group are arrayparameters with index 0 to 2. Select index 0 to programmetimer 0, select index 1 to programme timer 1, and so on.13-20 SL Controller TimerArray [3]Range: Function:Sizerelated*[ 0 -0 ]Enter the value to define the duration ofthe FALSE output from the programmedtimer. A timer is only FALSE if it is startedby an action (for example [29] Start timer1) and until the given timer value haselapsed.3.13.5 13-4* Logic RulesCombine up to 3 boolean inputs (TRUE/FALSE inputs) fromtimers, comparators, digital inputs, status bits, and eventsusing the logical operators AND, OR, and NOT. Selectboolean inputs for the calculation in parameter 13-40 LogicRule Boolean 1, parameter 13-42 Logic Rule Boolean 2, andparameter 13-44 Logic Rule Boolean 3.
