applications for HVAC systems in chemical, pharmaceutical, industrial
and offshore/onshore plants, for use in Ex-areas zone 1, 2 (gas) and
zone 21, 22 (dust).
Highest protection class (ATEX) and IP66 protection, small dimensions,
only 3,5 kg weight, universal functions 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 and torques as well as
spring return times, according to the actuator type, are selectable or
adjustable on site. The integrated universal power supply is self adaptable
to input voltage of 24 VAC/DC. The actuators are 100 % overload protected
and self locking.
...Max-...-CYF actuators are equipped with spring return fail safe function.
Standard shaft connection is a double square direct coupling with

Electrical connection
All actuators are equipped with a universal supply unit working at a voltage of 24 VAC/DC.
The safety operation of the spring return function works if the supply voltage is cut.
An over-current protection fuse < 10 A has to be provided by installer.
Note: the initial current is appr. 2 A for 1 second.

24...240 VAC/DC
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
Turn switch (S) to position 02 (low torque) or 07 (high torque). Press button (T) for
a minimum of 3 seconds. The actuator drives to both end positions and detects the
blocking positions. The LED flashes GREEN during adjustment.
The adjustment takes about 60 seconds (30 sec. “On”, 30 sec. “Off”).
B) Selecting motor running time and torque
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 operation.
C) Additional information for operation
The rotation direction (clockwise/counter clockwise)depends on left/right
mounting of the actuator to the damper.
▪ Do not open the cover when circuits are live
▪ Connect potential earth
▪ Close all openings to ensure enclosure protection
▪ Clean only with damp cloth, avoid dust accumulation

EXPLOSIONPROOF
E. 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.
F. 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!
G. Synchron mode
Do not connect several actuators to one shaft or link mechanically together.
H. 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.
I. Intrinsically safe circuits
The actuator has a flameproof enclosure acc. to EN 60079. 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!

Important information for installation and operation
Extra information (see additional data sheet)
Additional technical information, dimensions, installation intruction, illustration
and failure indication
A. Installation, commissioning, maintenance
All national and international standards, rules and regulations for hazardous Ex-areas
must be complied with. 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 integrated
heater. During commissioning apply a self adjustment drive.
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 12 × 12 mm.
For round shafts there are adaptors/clamping connection (as accessories, e.g. KB-S)
available. The housing of the actuator is built axially symmetrically 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. 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.
Accessory ExBox – Ex-e terminal boxAccessory ExSwitch – Ex-d auxiliary switch
For electrical connection of the ...Max actuator in a hazardous
area an explosion proof terminal box is required.
To adapt the ...Box directly to the actuator housing a mounting
bracket is required.
ExBox- Y/S for ...Max-...-CY and ...-CYF
For an end or inclined position indication it is possible to
retrofit external, adjustable, explosion proof auxiliary switches
type ExSwitch.
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.
