Figure 5.70 EP Damper Control - HVAC Switch Group Type 4
Figure 5.70 depicts an EP damper in an HVAC system with the capability of
CLOSED control, switch group type 4. In the above configura-
tion, the CON
OFFCL
CM is activated. The CON
OFFCL
CM controls a normally open contactor for the pressure switch power line. When the
CON
OFFCL
CM is activated, the normally open contactor is closed. When the contactor closes, power is supplied to the pressure switch
which cuts the airflow to the damper, closing the damper. When the CON
OFFCL
CM is deactivated, the EMS is free to control the damper.
The EMS is currently being overridden by the CON
OFFCL
CM.
