Specification
ExMax and RedMax actuators size S are equipped with a 12 x 12 mm (double square) shaft connection. The form-fitting shaft connection is the securest connection between damper
shaft and actuator because slipping or slipping through is avoided compared to the force-fit clamp-connection. The actuator will be connected firmly by means of four screws
M 4 x 100 (scope of supply) to the damper. For the connection to round damper shaft or square damper shaft with smaller or larger 12x12 mm an optional mounting clamp
(type KB-S) for tensionally locked connections is available.

It is to be considered that the actuators have a total angle movement of approx. 95°
in order to realize a pre-tention on the damper. Therefore the actuator sits tilted on the
damper shaft. In order to prevent this and to assure pre-tention to the damper the driving
shaft has to be adjusted mechanically before connecting to the damper shaft.
The provided socket wrench serves for the mechanical adjustment over the hand-operated
control socket HV. The actuators are axially symmetrically developed. In case of spring
return function the safety postion must be selected by turning the actuator 180°.
Mounting:
1. Affix tap hole M6 (in accordance with drill template) on the damper or to a mounting
bracket.
2. Adjust drive shaft of the actuator with the socket wrench that the drive stands
perpendicular to the damper before pluging actuator on to the damper shaft.
3. Plug actuator onto damper shaft and fix diagonally with 2 screws.
4. Remove the socket wrench.
5. Pivot and tighten the remaining screws.
Note: the drive shaft is selflockingly produced and may only be mechanically adjusted
either with the provided socket wrench or the optional accessory "HV-S" manual override.
External applied force to the shaft can lead to mechanical damage of the actuator.
Dimension damper shaft
4 screws M4 x 100, as well as a socket wrench, are part of delivery for ExMax/RedMax
actuators size "S".
For damper shafts 9 x 9, 10 x 10 or 11 x 11 mm reducing bush are optional available.
The actuators are axially symmetrically developed. In case of a spring return function
the safety position must be selected by turning the actuator 180°.
Mounting
1. Insert u-bold connection into drive-shaft and screw the bold from the opposite side
tight with the socket wrench.
2. Screw in two screws functioning as an anti twist locking device.
3. Install mounting bracket at the damper.
4. Plug the actuator to the damper shaft, adjust the actuator in the mounting brackets
position and tighten the damper shaft with a wrench socket via the u-bold connection.
Attention!
The actuator must be installed in such a way that it can implement an easy oscillating
motion in the mounting bracket for the reconciliation of the not centric connection.
Note: the drive shaft is selflockingly produced and may only be mechanically adjusted
either with the provided socket wrench or the optional accessory "HV-S" manual override.
External applied force to the shaft can lead to mechanical damage of the actuator.
