Solid state dual automatic closer “timer”:
Red and green warning lights (60 watts bulb maximum). If door is closed, push of button starts door up and turns green light on for a preset time. (Adjustable without tools from 5 seconds to 180 seconds). At the end of the preset time, the red lights is turned on for 5 seconds to 90 seconds (adjustable) and the door closes automatically. If button is pressed or any other control used to open door, while door is travelling downward, it will instantly reverse to open position and reset cycle of timer. If door is in the open position and button or any other control used to close door is activated, timer will automatically reset to preset timing.
Toggle switch:
Is provided to cut out timer when automatic closing is not desired, such as in summer.
Limit switches:
