Application

This kit contains an N800-0555 positive positioning relay, an

N800-1501 feedback arm, and springs for 5 psi and 10 psi

spans for the M556, M573, and M574 pneumatic damper

actuators.

Installation

INSPECTION

Inspect the package for damage. If damaged, notify the

appropriate carrier immediately. If undamaged, open the

package and inspect the kit for any obvious damage. Return

damaged products.

MOUNTING

The positioner is designed to mount on one of the housing

screw posts of the M556, M573, or M574 pneumatic actuators.

1. Select the position required.

2. Remove the selected housing screw.

3. Slide the positioner over the screw post and securely

reinsert the screw.

4. Unthread the clevis or ball joint from the actuator shaft.

5. Align the holes in the feedback arm (Figure-1) and the

shaft fitting.

6. Insert the threaded end of the shaft fitting through the

appropriate hole in the feedback arm, and rethread the

fitting into the output shaft. Do not tighten securely.

7. Remove the appropriate spring from the kit. (Refer to

Table-1 for selections.) Hook one end of the spring onto

the positioner (Figure-2) and the other end into the

spring hole in the end of the feedback arm (Figure-1).

8. Align the feedback arm so that the spring is perpendicular

to the positioner.

9. Tighten the shaft fitting securely to the output shaft.

PIPING

Refer to Figure-2. The positioner requires a signal connection

to “S” and a main air connection to “M”. The positioner output,

located above the needle-valve, is connected to the actuator

signal port. Fittings are provided for 1/4 in. O.D. plastic tubing.

ADJUSTABLE NEEDLE-VALVE Refer to Figure-2. The needle-valve allows the adjustment of the rate of actuator movement. With this needle-valve, the speed of the M556, M573, and M574 actuators may be adjusted with a small blade screwdriver, if required, to: Feedback Spring M573 M574 Give the actuators the same relative rate of movement M556 This makes it possible, for example, to have outside, return, and relief dampers on an air handling unit move together, rather than at different rates.
