Figure 5.78 EP Damper Control - HVAC Switch Group Type 12
Figure 5.78 depicts an EP damper in an HVAC system with the capability of
OPEN and CLOSED control, switch group type 12. In the above
configuration, the CON
ONOP
CM is activated and the CON
OFFCL
CM is deactivated. The CON
ONOP
CM controls normally closed contactor
for the pressure switch power line. When the CON
ONOP
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
ONOP
CM is deactivated, the EMS is free to
control the damper. The EMS is currently being overridden by the CON
ONOP
CM.
