Slaved Zone Damper Wiring
For large zones, it may be necessary to have more than one air damper
controlled by a Non-Modular VAV/Zone Controller Actuator Package
and its associated space sensor. The Orion system allows for connecting
up to two additional slaved zone dampers to the master Non-Modular
VAV/Zone Controller Actuator Package.
Slaving is not available for
pressure independent damper applications.
Note:
Each slaved actuator is considered a modular device
rated at 6 VA each. This 6 VA load must be included in
the transformer sizing and branch circuit calculations
for the Power/Comm board. See the previous section
regarding transformer sizing of the Power/Comm board
for complete information.
Two Slave Wiring Adapters (OE267) consisting of a slave wiring inter-
face card and modular cable are supplied with the OE523 Round Slaved
Zone Damper, OE738 Slaved VAV/Zone Rectangular Damper Kit, and
the
OE282-03 Slaved VAV/Zone Damper Kit. These are required when
attaching slave actuator(s) to the master zone damper. One slave wiring
interface card should be mounted near the control enclosure of the master
Non-Modular VAV/Zone Controller Actuator Package. It is mounted by
fastening the plastic snap-track to suitable sheet metal mounting surface
with the sheet metal screws provided. The other card is mounted in the
control enclosure of the slaved zone damper. Run 24 AWG minimum
wire between the slave wiring interface cards. Connect modular cables
to the slave wiring interface cards and to the zone actuators as shown.
