i2/b3 865/866/885-V Controller Installation

To install the controller, follow these steps:

1. Check the mounting location for the Andover Continuum i2 or b3
865/866/885-V controller. The unit is typically mounted with the
controller extending down or to the right from the damper shaft.
However, the controller can be operated in any position within
the vertical plane.

Note: Installing the controller to the right (with the barbed

ttings pointing down) helps prevent condensate from
migrating into the on-board velocity sensor.

With a downward extension, the available area around the damp-

er shaft must measure 6” (160 mm) down from the lower edge
of the shaft, 4.5” (120 mm) to the right, 1.5” (40 mm) to the left
and 1.75” (45 mm) above the shaft. Ensure the location allows
enough clearance for servicing.

2. The actuator is designed to mount over a

/2” (12.7 mm) diameter
shaft with a minimum of 2.5” (63.5 mm) of exposed shaft. If the
damper shaft diameter is less than 1/2” (12.7 mm) an adapter is
required. An adapter (p/n AM-135) is available from Schneider
Electric to allow mounting on 3/8” (9.5 mm) damper shaft. The
865/866/885-V controller will not work with larger damper shaft
diameters.

(25.4 mm) long, move the two damper shaft mounting screws to the
alternate lower damper shaft positions.

for the operation of the actuator. Position the mounting clip in the
desired mounting bracket. Do not insert the clip more than half-way
into the bracket. This allows the clip and the back of the actuator to
properly align with the VAV box.

Each controller on the network must have its own
24V Step-Down or Isolation Transformer. Be sure to
wire the secondary of the 24V Step-Down Transformer
exactly as shown. Pin 11 must be connected to the grounded
side of the secondary on all transformers used in the system.
Otherwise, damage to one or more controllers may result.

Class 2 power only!

5. Press and hold the green actuator clutch release and rotate the
VAV damper shaft by hand to the fully closed position. Note
whether the damper is rotated clockwise (CW) or counter-clock­wise (CCW) to close.

6. Slip the controller over the damper shaft. Position the actuator
and, using a self tapping sheet metal screw, secure the mount­ing clip to the VAV box.

7. Next, press the actuator toward the box until the actuator comes
into contact with the VAV box, the mounting clip snaps into the
bracket, or the back of the actuator comes into contact with the
VAV box.

8. Press and hold the green actuator clutch release (see Figure on
cover page) and rotate the actuator collar to a nearly closed
position, the 5° index mark, if the damper shaft was rotated
counter-clockwise to close (Step 5). Rotate the actuator collar to
the 85° index mark if the damper shaft was rotated clockwise to
close (Step 5).

9. Tighten the two damper hex mounting screws using a

/8” hex
Allen wrench. The minimum torque required to secure the con­troller to the damper shaft depends on the shaft material. The
maximum torque for the socket screws is 30 inch-pounds (3.4
Nm).

AC Power Connection

Note: The damper should rotate freely when the clutch is released.

If it does not, the actuator may not be properly aligned with
the damper shaft – it may be necessary to repeat Steps 4
through 9 using a new orientation.

10. If the damper does not provide a mechanical stop in the open direction,
or it is not desirable to use the damper’s open stop, set the adjustable
stops on the 865/866/885-V controller to the desired position. Use a

1

/4” hex driver to adjust the screw stop on the controller.

Note: For the 866-V model only, you must calibrate the damper

position feedback reporting option before using. You
calibrate damper position feedback reporting by changing
the damper’s output attribute, LCDState, from DISABLED
to ENABLED. The attribute, OverrideValue, indicates the
damper position as a fractional value from 0 (at the closed
stop) to 1 (at the open stop).

Whenever the Actuator Clutch Release button is pressed and
the Actuator is moved manually, you need to recalibrate
damper position feedback reporting. During damper
calibration, the damper output will rotate from one end- stop
to the other and then return to its original position. It is also
recommended that you periodically recalibrate damper position
feedback reporting using a Plain English (PE) program.

Note: Use care when attaching power wiring to these connectors. They are not to be used as a strain relief.
The connectors cannot withstand excessive bending or exing.
Failing to install this transformer on remote controllers can damage it and other controllers on the network.

Wiring Rules

These modules are intended for installation
within the enclosure of another product.

Do not remotely ground any part of the input sensor wiring.

Remote grounds connected to the return terminal could make
the system operate incorrectly or damage the equipment.

The signal return is not true earth ground. It is an electronic
reference point necessary to interpret the sensor properly.

For reliable input operation, follow these input wiring guidelines:

• Never lay wires across the surface of a printed circuit board.

• Wires should never be within 1” or 25 mm of any component
on a printed circuit board.

• Use shielded input wire.

• Terminate the shield of the input wires at one end of the run
only — preferably at the end where your I/O module is located.

• When stripping wire, be careful not to drop small pieces of wire
inside the cabinet.

• Don’t run your input wiring in the same conduit with AC power.

• Don’t run your input wiring in the same conduit with your
output wiring.

Grounding the Controller

To insure proper operation of the controller, it must be connected to a
good earth ground. The connection must be made as close to the module
as possible.

Caution: Earth ground ( ) must be connected to avoid

module damage.

Removing the Plastic Battery Tab

Before operating the controller, open the cover and remove the
protective plastic battery tab. The battery location is shown in the
illlustration on the cover page.

Connecting the Air Velocity Sensor

4’

(1.2 m)

Tubing (Max.)

1. Connect the low pressure side of the velocity sensor to the barbed
tting labeled P1 (LO) on the controller.

2. Connect the high pressure side of the velocity sensor to the tting
labeled P2 (HI) on the controller.

Notes: Use a recommended maximum length of 4’ (1.2 m) FRPE
plyetheylene tubing or 0.25” (6.34 mm) O.D. and 0.125”
(3.175 mm) I.D. Tygon tubing.

Do not expose the velocity sensor to moisture. If moisture
condensation is a potential problem, orient the tubing and
controller so that the barbed ttings are above the lowest
part of the tubing to create a moisture trap.
