Figure 5.35 EP Damper Control, Non-dedicated System - FSCS Switch Group Type 4
Figure 5.35 depicts an EP damper in a non-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 line. When CON
ON⁄OP
CM is activated, the normally closed contactor is opened. When the contactor opens, power is
cut from the pressure switch, which allows airflow to open the damper. When the CON
ON⁄OP
CM is deactivated, the EMS is free to control
the damper. The EMS is currently being overridden by the CON
ON⁄OP
CM.
When power is cut from the pressure switch, the damper opens. When the damper completely opens, the damper open limit switch is
CLOSED
and the damper closed limit switch is
OPEN, indicating that the damper is in the OPEN position. The VER
OFF⁄CL
MM monitors the CLOSED
position of the limit switch. In this case the VER
OFF⁄CL
MM is deactivated because the damper is OPEN.
