Figure 5.25 Motorized Damper Control
Non-dedicated System - FSCS Switch Group Type 3
Figure 5.25 depicts a motorized damper in a non-dedicated system with the capability of
CLOSED control and verification of the OPEN and
CLOSED state, switch group type 3. In the above configuration, the CON
OFF⁄CL
CM is deactivated. The CON
OFF⁄CL
CM controls two contac-
tors: a normally closed contactor for the damper open power line, and a dual normally open/normally closed contactor for the damper close
power line. When the CON
OFF⁄CL
CM is activated, the normally closed contactor is opened (cutting any power supplied by the EMS to the
damper open power line), the normally closed portion of the dual contactor is opened (cutting any power supplied by the EMS to the damper
closed power line), and the normally open portion of the dual contactor is closed, thus supplying power to close the damper. When the
CON
OFF⁄CL
CM is deactivated, the EMS is free to control the damper. The EMS is currently 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 and the VER
ON⁄OP
MM monitors the CLOSED position of the damper open limit switch. In this case the VER
OFF⁄CL
MM is
activated and the VER
ON⁄OP
MM is deactivated because the damper is CLOSED.
