Figure 5.9 Motorized Damper Control
Dedicated System - FSCS Switch Group Type 5
Figure 5.9 depicts a motorized damper in a dedicated system with the capability of
OPEN
control and verification of the
OPEN
state, switch
group type 5. In the above configuration, the CON
ON⁄OP
CM is activated. The CON
ON⁄OP
CM controls a normally open contactor for the
damper open power line and a normally closed contactor for the damper close power. When the CON
ON⁄OP
CM is activated, the normally
closed contactor is opened and the normally open contactor is closed, thus supplying power to open the damper. When the damper com-
pletely opens, the damper open limit switch is
CLOSED
, indicating that the damper is in the
OPEN
position. The VER
ON⁄OP
MM monitors the
CLOSED
position of the open position limit switch. In this case the VER
ON⁄OP
MM is activated because the damper is
OPEN
.
