Figure 5.64 depicts a motorized damper in an HVAC system with the capability of
state, switch group type 13. In the above configuration, the CON

CON CM controls two contactors: a normally closed contactor for the damper closed power line, and a dual normally open/normally

closed contactor for the damper open power line. The CON

supplied by the EMS to the damper open power line), and the normally open portion of the dual contactor is closed, thus supplying power to
open the damper.
When power is supplied to the damper open power line, the damper opens. When the damper completely opens, the damper open limit
switch is , indicating that the damper is in the
CLOSED
limit switch. In this case the VER
