Figure 5.6 Motorized Damper Control
Dedicated System - FSCS Switch Group Type 2
Figure 5.6 depicts a motorized damper in a dedicated system with the capability of
CLOSED control and verification of the OPEN state, switch
group type 2. In the above configuration, the CON
OFF⁄CL
CM is activated. The CON
OFF⁄CL
CM controls a normally closed contact for the
damper open power line and a normally open contact for the damper close power. When the CON
OFF⁄CL
CM is activated, the normally closed
contact is opened and the normally open contactor is closed, thus supplying power to close the damper. When the damper completely closes,
the damper closed limit switch is
CLOSED, indicating that the damper is in the CLOSED position, and the damper open limit switch is OPEN.
The VER
ON⁄OP
MM monitors the CLOSED position of the damper open limit switch. In this case the VER
ON⁄OP
MM is deactivated because the
damper is
CLOSED.
