The LE-21 is a lock out module that has been designed to inhibit the approach-side SuperScan on an automatic door when the door is used manually. For instance, when the SuperScan is installed on a low energy operator that is to be used manually as well as automatically, the LE-21 will allow the SuperScan to be active only when the door is triggered by activating a push plate, such as on “knowing act” doors. The SuperScan will remain in the activation circuit until the door fully closes following the automatic operation of the door.
A door position switch must be used to indicate to the LE-21 that the door has reached its fully closed position and to ignore the input of the SuperScan until the push plate activates the door again. If the door is opened manually, the LE-21 will prohibit the input from the SuperScan from reaching the door control. The LE-21 provides the hold open time delay; therefore, the door control’s time delay should be set to minimum.
