Multiple Actuator Mounting

If more torque is required than one AF actuator can provide, a

second AF actuator may be mounted to the shaft using the

ZG-102 multiple mounting bracket.

Notes: The manual positioning mechanism cannot be used in

multiple actuator applications.

Special Wiring and Additional Information: See wiring guide

Rotation Limitation

The angle of rotation limiter, ZDB-AF2, is used in conjunction

with the tab on the universal clamp or IND-AF2 position indicator

which comes with the ZDB-AF2. In order to function properly,

the clamp or indicator must be mounted correctly. See Fig. A.

The ZDB-AF2 may not work in certain mounting orientations

using the ZG-106 or ZG-107 mounting brackets. It will not work

with the ZG-108 mounting bracket. Limiting the damper rotation

must be accomplished by adjusting the crankarm linkage.

The ZDB-AF2 may be used in 2 ways to control the rotational

output of the AF series actuator. One use is in the application

where a damper has a designed rotation less than 90°. An

example would be a 45° or 60° rotating damper. The other

application would be to set a minimum damper position which

can be easily set or changed without having to remove the

actuator from the damper.

Damper Rotation Limiting

1. Determine the amount of damper rotation required.

2. Locate the Angle of Rotation Limiter (ZDB-AF2) on the

actuator so that its edge lines up with the degree grad-

uation on the actuator face which corresponds with the

required rotation. See Fig. C.

3. Find the appropriate cross-hair location through the

slot of the limiter. This is the screw mounting location.

4. Pierce through the label material to allow easy fasten-

ing of the retaining screw.

5. Position the limiter back to the desired position, mak-

ing sure the locating "teeth" on the limiter are engaged

into the locating holes on the actuator.

Installation Instructions

6. Fasten the limiter to the actuator using the self tapping

screw provided.

7. Test the damper rotation either manually with the man-

ual crank or apply power and if required, a control sig-

nal. Re-adjust if necessary.

Mechanical Minimum Damper Position

In order to use this procedure, the actuator must be mount-

ed for short shaft mounting. See pages 8 & 10.

1. Position the damper to its minimum position by using

the manual crank or by providing the appropriate con-

trol signal to the AF24... modulating type actuator.

2. Place the indicator on to the actuator spline in the

approximate position shown in Fig. D. Fasten it with

the retaining clip. Note that the mounting orientation is

different than the mounting used for Damper Rotation

Limiting.

3. Place the ZDB-AF2 rotation limiter on the actuator so

that it either makes contact with, or is as close as pos-

sible to, the edge of the indicator. See Fig. E. Make

sure that the locating teeth are engaged into the locat-

ing holes on the actuator. If all of the mounting teeth

do not align with the holes, the mounting location of

the indicator to the spline may have to be moved. The

limiter would then be remounted to get the best posi-

tion match of both parts.

4. Find the cross-hair location through the slot of the lim-

iter. This is the screw mounting location.

5. Pierce through the label material to allow easy fasten-

ing of the retaining screw.

6. Fasten the limiter to the actuator using the self tapping

screw provided.

7. Test the damper operation either manually with the

manual crank or apply power and if required, a control

signal. Re-adjust if necessary.
