Zone Controller Actuator Package Wiring
Figure 7: Non-Modular VAV/Zone Controller Actuator Package Wiring
Wiring Considerations
The OE325-01 Zone Controller Expansion Module connects to the
Non-Modular VAV/Zone Controller Actuator Package by means of a
modular cable provided with the expansion module. Power is supplied
to the Zone Controller Expansion Module by means of this modular
cable. Screw terminals are provided for connection of field wiring to
the relay and analog outputs. The Expansion Module is used to supply
extra relays and/or analog outputs to control fan and heating functions
for the Non-Modular VAV/Zone Controller Actuator Package.
The OE325-01 Zone Controller Expansion Module is always shipped
loose for field mounting by others. Be careful not to damage the elec
-
tronic components when mounting the controller. Remove the controller
from its snap track mount. Mark the control enclosure base using the snap
track as a template. Drill pilot holes in the enclosure base and secure the
snap track to it using sheet metal screws. Do not allow metal shavings to
fall onto the circuit board. Re-attach the controller to the snap track. Be
sure the mounting location is close enough to the Non-Modular VAV/
Zone Controller Actuator Package so that the supplied modular cable
will reach from it to the Zone Controller Expansion Module.
Warning:
The 3 relay outputs available on the OE325-01
Expansion Module are each rated for 1 Amp. @ 24
VAC. If your device load exceeds these limits, a
pilot duty relay (by others) must be used in the
circuit.
The wiring consideration information previously outlined for the Non-
Modular VAV/Zone Controller Actuator Package should be followed
when wiring the OE325-01 Zone Controller Expansion Module.
