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

To install the controller, follow these steps:	2.	The actuator is designed to mount over a 1/2” (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/	” (12.7 mm) an adapter is

i2/b3 865/866/885-V Controller Installation (continued)

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-clock- wise (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 1/8” 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).

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 endstop 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.

	Otherwise, damage to one or more controllers may result.

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 flexing.

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.

•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.

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.

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
