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 an Ex-e terminal box, certificated in acc.
with ATEX is required (e.g. ExBox).
An over-current protection fuse < 10 A has to be provided by installer.
Note: the initial current is appr. 2 A for 1 second.
Installation
supply *
24...240 VAC/DC ± 10 %
* electrical wiring see diagrams
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. 180 sec. (90 sec. “On”, 90 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) Changing modulating mode into 3-pos. operation mode with feedback:
Push button (T) 3 times.
LED changes from permanent GREEN to permanent YELLOW.
Push button within following limits:
▪Push for min. 0,2 sec. each
▪Complete pushing (3 ×) within 5 sec.
LED – Status:
▪GREEN (permanent) – Supply available, actuator is active in modulating mode
▪YELLOW (permanent) – Supply available, actuator is active in 3-pos. (+ U) mode
D) Changing 3-pos. mode with feedback into modulating operation mode:
Push button (T) 3 ×. LED changes from permanent YELLOW to permanent GREEN.
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. In this case the Y-inputs are without function.
F) Reverse function:
Bridge between signal wise wiring 3–4 (cable B) gets a reverse function of input Y
and feedback signals U.

input and output signals

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 for hazardous Ex-areas
must be complied. Certified 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 installations
design, selection and erection, EN/IEC 60079-14 can be used.
For electrical connection an Ex-e terminal box is required (e.g. ExBox-...).
Attention: If the actuator is put out of operation all Ex rules and regulationsmust be
applied. You have to cut the supply voltage before opening the terminal box!
The cablesof 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 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 integral
heater.
Actuators are maintenance free. An annual inspection is recommended. For electrical
installations inspection and maintenance, EN/IEC 60079-17 can be used. 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 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
motor running times and spring return running times can be selected on site in acc. to
the actuator type.
D. 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.
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
automatically. Actuator will not run during heating process.
3. The adjustment options are only ensured after this heating up period.
G. 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!
H. Synchron mode
Do not connect several actuators to one shaft or link mechanically together.
I. Mechanical protection
The actuator must be operated with an outside load of at least 10 Nm.
After installing the actuator to the damper/armature an automatic alignment has to be ac-
complished 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 90 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.
J. Intrinsically safe circuits
The actuator itself has a flameproof enclosure. The supply of the push button (adjustment
drive), the 10-position switch (adjustment of torque and running time) and the LED
indicator is performed intrinsically safe!
Accessory ExBox – adaptable Ex-e terminal boxAccessory ExSwitch – adaptable Ex-d auxiliary switch
For electrical connection of ...Max actuators inside the
hazardous area an Ex-e terminal box is required.
ExBoxes are appropriate terminal boxes and placed at
the disposal. To adapt the ...Box directly to the actuator
housing a mounting bracket type MKK-M is required.
ExBox- Y/S for ...Max-...-Y and ...-YF with integral
auxiliary switches
For an end or inclined position indication it is possible to
retrofit external, adjustable, explosion proof auxiliary switches
type ExSwitch. 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.
