Figure 5.12 EP Damper Control, Dedicated System - FSCS Switch Group Type 2
Figure 5.12 depicts an EP 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 open contactor for the
pressure switch power. When the CON
OFF⁄CL
CM is activated, 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.
