5.5.2 Motorized Dampers
Figure 5.52 Motorized Damper Control - HVAC Switch Group Type 1
Figure 5.52 depicts a motorized damper in an HVAC system with the capability of verification of the
CLOSED state, switch group type 1. In
the above configuration, the EMS is supplying power to the damper closed power line. When power is supplied to the damper closed power
line, the damper closes. When the damper completely closes, the damper closed limit switch is CLOSED, indicating that the damper is in the
CLOSED position. The VER
OFF⁄CL
MM monitors the CLOSED position of the damper closed limit switch. In this case the VER
OFF⁄CL
MM is
activated because the damper is CLOSED.
