PRECAUTIONS
The LE-21 (PN: 10LE21) is a lock out module that has been designed to inhibit the Approach 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.
•
Shut off all power going to the header before attempting any wiring procedures.
•
Maintain a clean & safe environment when working in public areas.
•
Constantly be aware of pedestrian traffic around the door area.
•
Always stop pedestrian traffic through the doorway when performing tests that may result in unexpected
reactions by the door.
•
Always check placement of all wiring before powering up to insure that moving door parts will not catch
any wires and cause damage to equipment.
•
Ensure compliance with all applicable safety standards (i.e. ANSI A156.10 or A156.19) upon
completion of installation.
