End Switch Kit

For use on WD series Dampers

Field Installation Instructions

These instructions apply to the field installation of end switch kits on Greenheck model WD Backdraft Dampers. These end switch kits can be used in conjunction with MP-100, MP-200, and MP-300 Series actuators.

End switches are typically wired to a fan and/or to a light serving as an open/not open indicator. When the damper is powered open, one of the damper blades makes contact with the spring rod of the end switch which in turn makes a connection allowing power to flow to the fan and/or light. This set up would be used when it is desirable to ensure that the damper is fully open before the fan starts.

Instructions:

1.Position end switch such that the back side of damper blade trips the spring rod.

2.Mount end switch bracket to damper frame or ductwork using #10 x 12 in. self-drilling sheet metal screws
