Parameters, adjustments and failure indication
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.
For electrical connection inside hazardous areas a terminal box is required (e.g. RedBox).
An over-current protection fuse < 10 A has to be provided by installer.
Note: the initial current is appr. 2 A for 1 second.

Functions, adjustments and parameters
A) Self adjustment of angle of rotation:
Switch (S) into position 02 (low torque) or 07 (high torque), then push button (T) for
minimum 3 seconds. The actuator will drive into both end positions to be adjusted.
LED indicates GREEN.
Adjustment time needs approx. 60 sec. (30 sec. “On”, 30 sec. “Off”). After that, switch
(S) into the position acc. with your required torque and running time.
B) Selection of running time and torque:
Put switch (S) into the correct selected position in acc. to above table.
The selected parameter will work at next operation of the actuator.
Adjustment can be done even without supply voltage. If supply voltage
is available turn switch only if actuator is not running.
C) Running time spring return:
The running time of 3 or 10 sec. spring return is selected by wiring
(see wiring diagrams SB 7.0 and 7.1).
D) Function of a passive sensor in the Ex-i circuit:
If the sensor opens the Ex-i circuit the actuator runs into its safety end-position with
spring return.
E) Additional information for 3-pos. operation:
a closed, b open
= direction I
b closed, a open
= direction II
a and b closed
= motor doesn’t work
a and b opened
= motor doesn’t work
The rotation direction (I and II) depends on left/right mounting of the actuator to the
damper/valve. You can change direction of the motor by changing electrical wiring
of terminal 3 and 4.

E X P L O S I O N P R O O F
Important information for installation and operation
A. Installation, commissioning, maintenance
All national and international standards, rules and regulations for hazardous Ex-areas
must be complied. For electrical connection a terminal box is requested (e.g.
RedBox-...).
Attention: If the actuator is put out of operation all Ex rules and regulation must be
applied. You have to cut the supply voltage before opening a terminal box !
The cable of the actuator must be installed in a fixed position and protected against
mechanical and thermical damage. Connect potential earth. Avoid temperature transfer
from armature to actuator ! Close all openings with min. IP66. For outdoor installation a
protective housing against sun, rain and snow should be applied to the actuator as well
as a constant supply at terminal 1 and 2 for the integral heater. Actuators are maintenance
free. An annual inspection is recommended. Ex-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 12 × 12 mm.
For round shafts adaptors/clamping connection (accessories, e.g. KB-S) are available.
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
motor running times and spring return running times can be selected on site in acc. to
the actuator type.
D. Temperature trigger ...Pro-TT-...
The actuator ...Max-...-BF will work only with the temperature trigger ExPro-TT-...
E. Operation with 3 sec. motor running time
Note following:
1. The 3 sec. motor running time mode is only available in switch position 0 and 5 and
at a constant supply voltage applied for a minimum of 1 minute on terminal 1 and 2.
2. The actuator opens at voltage on terminal 3 (resp. closes) and closes at voltage on
terminal 4 (resp. opens) – depending on mounting position of the actuator.
3. The max. duty ratio is 10 % resp. 1 cycle /minute. Between two fully 3 sec. cycles in
the same direction there must be a minimum intermission of 1 minute. Trying to run
the actuator in the same direction in less than the required minimum of 1 minute the
function will be blocked for the rest of the idle period. Later the release for the next
cycle is made automatically by an internal timing relay.
4. Same function is applied on spring return actuators, fail safe operation is regarded
same as a motor running cycle.
5. Trying to use the 1 wire On-off methode in switch position 0 and 5, software changes
the motor running time temporarily and automatically to 15 s /90° to protect the actuator
for overheating due to uncontrolled duty ratio.
6. The actuator must be operated with an outside load of at least 3 Nm.
7. After installing the actuator to the damper /armature an automatic alignment has to
be accomplished in order to obtain a “gentle” blockade /stop. This function protects
the damper / armature by reducing the end position/blockade speed in order to avoid
mechanical overload. The actuator alignes specifically once with 30 s /90° onto each
end position and recognizes the blockade position in order to reduce the motor
performance during operation briefly before reaching the end /blockade position.
F. 3-position control mode
...Max actuators are in the best way suitable for the 3-pos. operation. To protect such
elements as gears and mounting elements against harmful influences like minimum
pulse time, ...Max actuators are protected via internal electronics. It ignores impulses
< 0.5 s, the cyclic duration must be min. 0.5 s. At changing direction the pause is 1 s.
G. 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.
H. 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
automatically. Actuator will not run during heating process.
3. The adjustment options are only ensured after this heating up period.
I. Excess temperatures
In acc. to the ATEX rules and regulations Ex actuators must be 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 !
J. Synchron mode
Do not connect several actuators to one shaft or link mechanically together.
K. Mechanical protection
The actuator must be operated with an outside load of at least 3 Nm.
After installing the actuator to the damper /armature an automatic alignment has to be accomplished in order to obtain a “gentle” blockade / stop. This function protects the
damper/armature by reducing the end position’s / blockade speed in order to avoid
mechanical overload. The actuator alignes specifically once with 30 s / 90° onto each
position and recognizes the blockade position in order to reduce the motor performance
during operation briefly before reaching the end/ blockade position.
L. Intrinsically safe circuits
The supply of the push button (adjustment drive), the 10-position switch (adjustment of
torque and running time), the LED indicator and the sensor connection ExPro-TT are
intrinsically safe !
M. Routine tests of fire dampers
For periodic inspection of fire dampers cut off the supply line (current of actuator).
The switch contact at ExPro-TT-... is only for test aims of actuator’s function.

Additional technical information, dimensions, installation instruction, illustration
and failure indication
Accessory RedSwitch – adaptable auxiliary switch
Accessory RedBox – adaptable terminal box
For an end or inclined position indication it is possible to
retrofit external, adjustable, explosion proof auxiliary switches
type RedSwitch. The switch housing is mounted directly to
the actuator and the switches are linked to the actuator’s
square connector. The switches deliver a potential free
output and can be adjusted separately. They are connected
by the included cable tail.
For electrical connection of ...Max actuators inside the
hazardous area a terminal box is required.
RedBoxes are appropriate terminal boxes and placed at
the disposal. To adapt the ...Box directly to the actuator
housing a mounting bracket type MKK-S is required.
