When you have set up your Conditions, you can fine-tune their impact by setting the following time restrictions (in seconds) on any event occurring as a result of the criteria being met. These restrictions are best explained in the context of pedestrian-activated traffic signals at a crossing:

• Time before action – a built-in minimum delay between the condition being met (e.g. the button being pushed) and the action (signals changing to red for cars and green for pedestrians) taking effect.
• Minimum activity period – enter a minimum period for any resulting activity (e.g. when lights do change to green, a minimum ‘walk’ period applies which allows a number of pedestrians to cross safely).
• Maximum activity period – enter a maximum period for the resulting activity. In our traffic signals example, this value would be set to equal the minimum activity period if the lights operated on a fixed-walk cycle.
• Minimum time between Actions – enter the minimum time to leave before the action is repeated again. In our example, if the lights have just changed from green to red, they will not change back to green for a while, even if the button has been pressed.
