Figure 5.10 Motorized Damper Control
Dedicated System - FSCS Switch Group Type 6
Figure 5.10 depicts a motorized damper in a dedicated system with the capability of
OPEN control and verification of the OPEN and CLOSED
state, switch group type 6. 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 nor-
mally closed contactor is opened and the normally open contactor is closed, thus supplying power to open the damper. When the damper
completely opens, the open position limit switch is closed, indicating that the damper is in the
OPEN position. (When the damper is in the
closed position, the closed position limit switch is
CLOSED.) The VER
ON⁄OP
MM monitors when the open position limit switch is CLOSED. In
this case the VER
ON⁄OP
MM is activated and the VER
OFF⁄CL
MM is deactivated because the damper is OPEN.
In a dedicated system, a damper would never need both
ON and OFF control. A damper for a dedicated system is either normally open and
would need to be closed or normally closed and would need to be opened. This is not true for a Non-dedicated system.
Switch group type 7 would never be needed unless redundancy in
OFF and ON control were necessary. Type 7 is used for ON and OFF control
and verification of the
OFF state. When the CON
ON⁄OP
CM is deactivated, the CON
OFF⁄CL
CM is activated, and vice versa. The CON
ON⁄OP
CM
controls a normally open contactor which switches the damper open power to the damper. The CON
OFF⁄CL
CM controls a normally open con-
tactor which switches damper close power to the damper. When the CON
ON⁄OP
CM is deactivated, the contactor is open, thus cutting damper
open power to the damper. When the CON
OFF⁄CL
CM is activated, the contactor is closed, thus supplying power to the fan. The same capabil-
