Specification
ExMax and RedMax actuators of the size S are equiped with a 12x12 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.
Specification
ExMax and RedMax actuators of the size S are equipped with a 12x12 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. ExMax-...-BF and RedMax-...-BF actuators
integrate an intrinsically safe circuit in order to connect a FireSafe sensor which works like a temperature limiter.

Assembly
It is to be considered that the actuators have a total angle of rotation of approx. 95°
in order to realize a pre-tention 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 M6 (in accordance with drill 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.
6. Mount temperatur limiter type Fire Safe
7. Mount terminal box
8. Wire connect actuator and sensor in the terminal box
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.
