and technical data, an integrated heater and an optional stainless steel
housing guarantee safe operation even under difficult environmental
conditions. High quality brushless motors guarantee long life.
All actuators are programmable and adjustable on site. Special tools or
equipment are not required. Motor running times are selectable or
adjustable on site. The integrated universal power supply is self adaptable
to input voltages in the range of 24...240 VAC/DC. The actuators are
100 % overload protected.
...Max-...-F3 actuators are equipped with spring return fail safe function.
Additionally the ...Max-...-SF3 and ...-BF3 actuators are equipped with
2 integrated, potential free auxiliary switches each and ...Max-...-BF3
comes with a tripping circuit for connecting the ...Pro-TT-... safety
temperature trigger. Standard shaft connection is a double square direct
coupling with 16 × 16 mm.
Different accessories are available to adapt auxiliary switches, terminal

Installation
supply *
24...240 VAC/DC ± 10 %
* electrical wiring see diagrams
All actuators are equipped with a universal supply unit working at a voltage range from
24...240 VAC/DC. The supply unit is self adjusting to the connected voltage!
The safety operation of the spring return function works if the supply voltage is cut or line 3 opened.
For electrical connection a terminal box is required (e.g. InBox).
An over-current protection fuse < 10 A has to be provided by installer.
Note: The initial current is appr. 2 A for 1 second.
Integrated auxiliary switches signal the rotation angle’s position. Umin and Imin change once
the switches were operated with higher voltage or current.
Attention
During commissioning apply a self adjustment drive.
Regard duty cycle at motor running times!
Never use spring return actuators without external load.

A) Self adjustment of angle of rotation
ATTENTION: To adjust the angle of rotation connect only wire 1 and 2.
Do not connect wire 3.
Apply supply voltage to wire 1 and 2. Turn switch (S) to position 02. Press
button (T) for a minimum of 3 seconds. The actuator drives to the first end posi-
tion, detects the blocking position and performs a spring return to the starting posi-
tion. The LED flashes GREEN during adjustment. After that disconnect from the
mains and connect wire 3.
The adjustment takes about 93 seconds (90 sec. “On”, 3 sec. “Off”).
B) Selecting motor running time
Adjust parameters only if actuator is in idle state or without applied potential.
Turn switch (S) to the position required for the intended operation acc. to table
above. The selected parameters will be carried out at the actuator’s next opera-
tion.
C) Function of the InPro-TT-... in the tripping circuit
When the ...Pro-TT’s tripping circuit is opened the actuator runs into its end posi-
tion with spring return.
D) Additional information for control in On-off operation
a closed = actuator opens
a open = spring return
The rotation direction (clockwise/counter clockwise) depends on left/right
mounting of the actuator to the damper.

Important information for installation and operation

Extra information (see additional data sheet)
Additional technical information, dimensions, installation instruction, illustration
and failure indication
A. Installation, commissioning, maintenance
All national and international standards, rules and regulations must be complied with. Apparatus
must be installed in accordance with manufacturer instructions. If the equipment is used in a manner
not specified by the manufacturer, the safety protection provided by the equipment may be impaired.
For electrical connection a terminal box is required (e.g. InBox-...).
Attention: If the actuator is put out of operation all rules and regulations must be applied.
You have to cut the supply voltage before opening the terminal box!
The cables of the actuator must be installed in a fixed position and protected
against mechanical and thermical damage. Connect potential earth. Avoid tem-
perature transfer from armature to actuator! Close all openings with min. IP67.
For outdoor installation a protective weather shield against sun, rain and snow
should be applied to the actuator as well as a constant supply at terminal 1 and
2 for the integrated heater. During commissioning apply a self adjustment drive.
Actuators are maintenance free. An annual inspection is recommended. Actuators must
not be opened by the customer.
B. Manual override
Manual override only if supply voltage is cut. Use delivered socket wrench with slow
motions, usage can be tight.
Attention: Releasing or letting go the Allen key too fast at manual operating actuators
with spring return causes risk of injury!
C. Shaft connection, selection of running time
Actuators are equipped with a direct coupling double square shaft connection of 16 × 16 mm.
The housing of the actuator is axially symmetrically built to select Open-close direction of
the spring return function by left-right mounting. Using the 10-position switch different mo-
tor running times and spring return running times can be selected on site in acc. to the actu-
ator type.
D. Temperature trigger ...Pro-TT-...
The actuator ...Max-...-BF3 will work only with the temperature trigger InPro-TT-...
E. Spring return
Spring return function works only if the supply voltage for terminal 1 or 2 is cut. In the
event of an electrical interruption, the spring returns to its end position even if supply
voltage is available again during return function. Thereafter operation will continue.
F. Operation at ambient temperatures below −20 °C
All actuators are equipped with a regulated integrated heating device designed for
employments down to −40 °C ambient temperature. The heater will be supplied automatically
by connecting the constant voltage supply on the clamps 1 and 2.
1. After mounting the actuator must bei immediately electrically connected.
2. The heater switches on automatically when actuator reaches internally −20 °C. It
heats up the actuator to a proper working temperature, then heater switches off au-
tomatically. Actuator will not run during heating process.
3. The adjustment options are only ensured after this heating up period.
G. Excess temperatures
All actuators are protected against excess temperature. The internal thermostat works
as a maximum limiter and, in the event of failure at incorrect temperatures, shuts off the
actuator irreversible. An upstream connected temperature sensor stops the actuator
before reaching its max. temperature. This safety feature is reversible, after cooling down
the actuator is completely functional again. In this case the failure must be eliminated
immediately on site!
H. Synchron mode
Do not connect several actuators to one shaft or link mechanically together.
I. Mechanical protection
Actuators must be operated with a minimum external load.
After installing the actuator to the damper/armature a self adjustment drive has to be
performed in order to protect the damper/armature against mechanical overload.
During operation the actuator reduces briefly its speed (motor power) before reaching
the end position for a “gentle” blockade/stop.
J. Routine tests of fire dampers
For periodic inspection of fire dampers cut off the supply line (current of actuator).
The test button at InPro-TT-... is only for test aims of actuator’s function.
For an end or inclined position indication it is possible to
retrofit external, adjustable auxiliary switches type
InSwitch.
The ...Switch is mounted directly to the actuator. The
switches deliver a potential free output and can be adjusted
separately. They are connected by cable.
For electrical connection of the ...Max actuator a terminal
box is required.
To adapt the ...Box directly to the actuator housing a mounting
bracket is required.
