Mounting instructions for actuators size M on butterfly valve and ball valve
Specification
Actuators of the size M are equiped with a 16 × 16 mm (double square) form-fitting shaft connection. For mounting to butterfly valves or ball valve a special mounting bracket in acc. with
DIN EN ISIO 5211 is required. Since this standard provides only certain basic conditions there can be substantial geometrical differences between armatures which require a special adaption.

Mounting instructions for actuators Size M on fire dampers
Specification
Actuators of the size M are equipped with a 16 × 16 mm (double square) form-fitting shaft connection. The form-fitting shaft connection is the securest connection between damper
shaft and actuator. The actuator is fixed with four screws directly to the fire damper and/or fixed to a mounting bracket. ...-BF actuators integrate an intrinsically safe circuit in order to
connect a ExPro-TT-.. sensor which works like a temperature limiter. InMax and InPro-TT is for non hazardous areas.
Assembly
It is to be considered that the actuators have a total angle of rotation of approx. 95° in
order to realize a pretention on the damper. Therefore thr 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 a spring return
function the safety postion must be selected by turning the actuator 180°.

Mounting:
1. Affix tap hole M8 (in accordance with drill drill template) on the damper or to a
2. Adjust drive shaft of the actuator with the socket wrench that the drive stands
3. Plug actuator onto damper shaft and fix diagonally with 2 screws.
4. Remove the socket wrench.
5. Pivot and tighten the remaining screws.
6. Mount temperatur limiter type ExPro-TT-.. / InPro-TT-..
7. Mount terminal box
8. Connect sensor on actuator
Note: the drive shaft is selflockingly produced and may only be mechanically adjusted
either with the provided socket wrench or the optional accessory „HV-M" manual override.
External applied force to the shaft can lead to mechanical damage of the actuator.
