All actuators are equipped with a 10-position switch, a push button and a multicolour LED
for calibration. These control elements are to be found cable-laterally behind the two middle
sectioned dummy plugs. For operation these must be removed. The calibration can be
achieved despite lining up power supply at the actuator. The explosion prevention is not
impaired thereby. However, it has to be of great concern that the dummy plugs must be
rescrewed in order to comply with the IP-protection class.
The operation of the switch and button has to be done by means of a small screwdriver.
Force with strong pressure and /or rotation is to be avoided in any case, since otherwise
control electronics can be damaged irreparably. Adjustments of torque and running time
can be achieved also before mounting. The adjustment of angle of rotation can be started
only with an outside load and accurate mounting.
When mounting actuator outdoors it has to be certain that the actuator is protected against
direct sun exposure (heat and UV!), rain and snow by employing an enclosure roof. Supply
voltage is to be applied immediately after mounting in order to assure integrated heating
at start.
Since actuators must have an internal temperature fuse, they may not be exposed to a too
high temperature, neither at storage nor during operation. Otherwise the fuse could respond
and switch off the actuator irreversibly.

Extra information for ...Max – size M
►Mounting on air dampers
Dimension of the damper shaft
4 screws M8 × 140 mm as well as a socket wrench are part of delivery.
For square damper shafts 12 × 12 mm or 14 × 14 mm reducing bushes
are available as optional accessories.
Length A
Measure A in acc. with indicator:
1. Actuator without indicator A = no limit
2. Actuator with indicator,
no accessories A < 95 mm
...Max actuators size M are equipped with a 16 × 16 mm (double square) shaft connection
by default. The form-fitting shaft connection is the most secure 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 to the damper or fixed to a mounting bracket by
means of four screws M8 (scope of delivery).
For square damper shafts 12 × 12 mm or 14 × 14 mm reducing bushes are also available.
The actuators are axially symmetric developed. In case of spring return function the safety
position must be selected by turning the actuator to 180°.
Furthermore it is to be considered that the actuators have a total angle movement of
approx. 95° in order to realize a pretension on the control element (damper or the like).
Therefore the actuator sits tilted on the damper shaft.
Attention: Mount with appropriate safety precautions only!
▪The drive shaft may only be mechanically adjusted either with the provided
socket wrench or the optional accessory “HV-MK” manual override (turn off
power supply). External force applied to the shaft can lead to mechanical damage
of the actuator!
▪At the manual override counteracting forces occure when mounting spring return
actuators. Do NOT release manual override under spring tension!
Mounting:
1. Affix tap holes M8 (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
perpendicularly to the damper before plugging actuator onto 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.
In order to adjust this and to induce pretension, the driving shaft has to be alined mechanically
over the hand-operated control socket “HV” when connecting to the damper shaft.
The socket wrench has to be turned counterclockwise when facing the actuator’s “side R”,
facing “side L” turn manual override clockwise.

Extra information for ...Max – size M
►Mounting to ball valves and butterfly valves
Mounting to a ball valve Mounting to a butterfly valve
Actuators of size M are equipped by default with a 16 × 16 mm double square form-fitting
shaft connection. For mounting to butterfly valves or ball valves a special mounting
bracket in acc. with DIN EN ISO 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 on fire dampers
The temperature trigger is mounted directly to the duct or damper wall with pre-assembled
tapping screws. The position of the safety elements must guarantee free air flow.
...Pro-TT-... is mounted to the actuator by means of quick fastener M12.
Connection of safety temperature trigger ...Pro-TT-...
Mounting:
1. Affix tap holes M8 (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
perpendicularly to the damper before plugging actuator onto 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 temperature trigger ...Pro-TT-...
7. Mount terminal box (type ...Box-BF)
8. Plug sensor connector into actuator’s socket
ExMax-...-BF and RedMax-...-BF actuators integrate an intrinsically safe circuit in
order to connect an ExPro-TT-... sensor which works like a temperature trigger.
InMax-... and InPro-TT-... are for non hazardous areas.

►Cross sections of the inlet line
Pannel Terminal box Actuator
Line cross section „A“ [mm²]
Voltage
„UV“ [V]
Example:
24 V power supply with wire diameter 1.5 mm² = cable length 126 m
For calculation following characteristics are essential:
UV= supply voltage [V]
A = line cross section [mm²]
L = conduit length [m]
Factor 0.0714 = drive specific factor [ Vmm² / m ]
(based on the electrical conductivity of
electrolytic copper with a coefficient of 56 m/ Ωmm²)
Maximum cable length L at existing cross section A
Required cable cross section A at existing cable length L
Example: A = 1.5 mm², UV= 24 V
Length of cable L = 126 m
Example: L = 250 m, UV= 30 V
Cross section A = 1,5 mm²
On long distances between voltage supply and drive, voltage drops occur due to line
resistances. As a consequence with 24 VAC/DC the actuator receives a too low
tension and does not start. In order to prevent this the cross section of the inlet line
is to be dimensioned accordingly.
The accompanying formulas allow the calculation of the necessary line cross section
respectively maximal permitted conduit length respectively utilizing the existing line
cross section.
Alternatively the secondary voltage can be increased by selecting a transformer.

Voltage Current

240 V AC INominal
The design of the on-site supply depends on the selected motor running time and
selected supply voltage. Accompanying values are “about values” since there can be
construction unit dispersions within electronics. The holding power is run time independently
typical at ~5 W. The power consumption for the heater is ~16 W. In the heating phase
the motor is not active!
The initial starting supply voltage required by the actuators power supply unit is ~ 2.0 A.
The starting pulse takes about 1 sec. (please consider this while concepting the cross
section of the supply line). The power factor is between 0.8 and 0.5 in dependence of
motor running time. A line protection should be min. 2 AT.
