LP-FXZAN13-0 Zone Controller and Actuator Assembly
Application
The LP-FXZAN13-0 Zone Controller and Actuator
Assembly (hereafter referred to as the FXZAN) is a
digital controller and actuator assembly designed
specifically for use with the Facility Explorer
Commercial Zoning Package.
2.
Position the actuator on the damper shaft so that
the damper shaft protrudes through the actuator
coupler.
3.
Verify that the actuator is in the desired mounting
position, parallel to the mounting surface.
4.
Hold the actuator in place on the damper shaft,
and insert a No. 10 self-drilling sheet metal screw
through the shoulder washer.
5.
Place an 8 mm (5/16 in.) socket on the screw and
use a drill and extension to drill the screw into the
mounting surface. Drive the screw until it is tight
against the washer. Do not overtighten the
mounting screw; it may strip the threads.
6.
Make a note of the rotation range and direction,
either Clockwise (CW) or Counterclockwise
(CCW), required to open the damper. See
Figure 2.
Installation
Prepare the FXZAN for mounting using the following
procedure:
1.
Check that you have the essential equipment and
tools and ensure the installation site meets
environmental requirements.
2.
Make sure the mounting location has adequate
clearance for future servicing.
Mounting
Location Considerations
Consider the following when positioning and orienting
the FXZAN:
•
Mount the FXZAN on a vertical, flat surface where
it functions best, such as the side of the zone
damper.
•
Verify wiring terminals are accessible.
•
Ensure that no extra mounting brackets, linkage,
or couplers are required for standard mounting.
•
Locate the FXZAN so that it has adequate
clearance for future servicing and is protected
from moisture and corrosive fumes.
To mount the FXZAN:
1.
Check that the damper blade is accessible or its
position is permanently marked on the end of the
damper shaft as illustrated in Figure 1.
7.
Figure 2: Damper Rotation
Grasp the damper shaft firmly with pliers and
either manually close the damper (90° boxes) or
manually open the damper (45 or 60° boxes).

8.
Press and hold the gear release lever, and rotate
the actuator coupler until it contacts the
mechanical end stop at either the fully closed (90°
boxes) or fully open (45 or 60° boxes) position.
Read these precautions before touching the terminals
or wiring the FXZAN and its accessories:
•
Make all wiring connections in accordance with the
National Electrical Code (NEC) and state and local
regulations. For transformer primaries above
150 VAC, the secondary must be earth-grounded
at the transformer to meet NEC. Since the power
supply for the FXZAN is not isolated, earth ground
can be introduced into the system. Avoid multiple
earth ground paths and use isolation transformers
if necessary.
•
Locate the equipment and route the wiring so that
twisted pair signal wiring is separated from power
wiring by at least 150 mm (6 in.).
•
Make all wiring connections to the FXZAN using
only copper conductors. To establish tight, reliable
electrical connections, use the correct wire sizes
for the terminals. Avoid very thin solid wires, such
as 26 AWG or less than 0.6 mm, which tend to
break.
•
Use a daisy-chained configuration for the N2 Bus.
The use of Y or T connections without a repeater
installed as the T-tap may cause a loss of
communications. Make sure there is at least one
End-of-Line termination on the N2 Bus (the FX16
or FX40 Series controller).
•
Do not run N2 Bus, Analog Input (AI), Binary Input
(BI), Analog Output (AO), or Binary Output (BO)
wiring in the same conduit as line voltage wiring
(above 30 VAC), or with wiring that switches
power to highly inductive loads such as
contactors, coils, motors, or generators.
•
Run AI, AO, and BI wiring in the same bundle or
conduit where convenient. If the BO wiring is not
wired through other switches or contacts, such as
actuator end-of-travel switches, bundle it with the
other Input/Output (I/O) wiring where convenient.
If the damper for the 90° boxes closes
counterclockwise, then rotate the coupler to the
counterclockwise mechanical limit. If the damper
for the 90° boxes closes clockwise, then rotate
the coupler to the clockwise mechanical limit.
The open end stop is automatically set for 90°
boxes. Hard stops must be provided for 45° and
60° boxes at both fully closed and fully open
damper positions. By installing the FXZAN at the
fully open position, the FXZAN provides the open
stop for 45° and 60° boxes.
9.
Using a crescent wrench, an 8 mm (5/16 in.)
square wrench, or a 10 mm (3/8 in.), 12-point
socket wrench, tighten the actuator set screw to
the damper shaft to 17 to 21 N⋅m (150 to
185 lb in. [14 lb⋅ft]).
10. Push the gear release lever down and turn the
actuator coupler by hand to ensure that the
damper can rotate from full closed to full open
without binding.
Note:
For proper operation, the actuator’s
mechanical stop should engage when the
damper is fully open. The damper seal should
engage when the damper is fully closed.
Wiring
!
WARNING: Risk of Electric Shock.
Disconnect each of multiple power supplies before
making electrical connections. More than one
disconnect may be required to completely
de-energize equipment. Contact with components
carrying hazardous voltage can cause electric shock
and may result in severe personal injury or death.
IMPORTANT:
Binary outputs DO1 and DO2
are connected to the M9104-AGA-3S actuator. If
disconnected, do not allow the outputs to short when
they are energized.
Use the following general wiring considerations:
•
The FXZAN includes isolated N2 and isolated
binary outputs DO3 – DO6.
•
The 24 VAC power input is not internally
transformer-isolated by the FXZAN.
•
The FXZAN is not meant for high voltage.
To wire the FXZAN:
1. Terminate wiring per the engineering drawings.
2. Install the N2 Bus to the FX16 Master Controller in
a daisy chain only (see Figure 3.)
3. Connect power to the FXZAN.
4. Commission and balance the FXZAN.
