Figure 5.14 EP Damper Control, Dedicated System - FSCS Switch Group Type 4
Figure 5.14 depicts an EP damper in a dedicated system with the capability of
OPEN control and verification of the CLOSED state, switch
group type 4. In the above configuration, the CON
ON⁄OP
CM is activated. The CON
ON⁄OP
CM controls a normally closed contactor for the
pressure switch power. When the CON
ON⁄OP
CM is activated, the normally closed contactor is opened, thus cutting power from the pressure
switch and causing the damper to open. When the damper completely opens, the damper open limit switch is
CLOSED, indicating that the
damper is in the
OPEN position, and the damper closed limit switch is OPEN. The VER
OFF⁄CL
MM monitors the CLOSED position of the damper
closed limit switch. In this case the VER
OFF⁄CL
MM is deactivated because the damper is CLOSED.
