Installation Instructions
Mechanical Installation
Multiple Actuator Mounting
If more torque is required than one TAF actuator can provide,
a second TAF 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 Figure 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 TAF series actuator. One use is in the applica-
tion 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 Figure 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.
6. Fasten the limiter to the actuator using the self tapping
screw provided.
7. Test the damper rotation either manually with the
manual crank or apply power and if required, a control
signal. 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 page 20.
1. Position the damper to its minimum position by using
the manual crank or by providing the appropriate con-
trol signal to the TAF24… modulating type actuator.
2. Place the indicator on to the actuator spline in the
approximate position shown in Figure 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
possible to, the edge of the indicator. See Figure E.
Make sure that the locating teeth are engaged into the
locating 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
position match of both parts.
4. Find the cross-hair location through the slot of the
limiter. This is the screw mounting location.
5. Pierce through the label material to allow easy
fastening 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.
