Figure 5.53 Motorized Damper Control - HVAC Switch Group Type 2
Figure 5.53 depicts a motorized damper in an HVAC system with the capability of verification of the OPEN state, switch group type 2. 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
ON⁄OP
MM monitors the CLOSED position of the damper open limit switch. In this case the VER
ON⁄OP
MM is deac-
tivated because the damper is
CLOSED.
