Ball valve Throttle valveSafety damper
Description Highlights
The RedMax actuators are a revolution for safety, control and shut-off dampers, VAV systems, ball valves, throttle valves and other motorized applications for HVAC systems in chemical, pharmaceutical, industrial and offshore/onshore plants, for use in Ex-areas zone 2 (gas) and zone 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 voltages in the range of 24...240 VAC/DC. Furthermore it is possible to perform control signal inverting and compulsion control by certain connections. The actuators are 100 % overload protected and self locking. ...Max-...-YF actuators are equipped with spring return fail safe function. Standard shaft connection is a double square direct coupling with 12 × 12 mm. Different accessories are available to adapt auxiliary switches, terminal boxes or adaptions for ball valves and throttle valves and other armatures.

Electrical connection
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 diagrams).
D) 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
E) Changing 3-pos. mode with feedback into modulating operation mode:
Push button (T) 3 ×. LED changes from permanent YELLOW to permanent GREEN.
F) 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 open = 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.
G) Reverse function:
Bridge between signal wise wiring 3–4 (cable B) gets a reverse function of input Y and feedback signals U.

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. 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. RedBox-...). Attention: If the actuator is put out of operation all Ex 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 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 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. 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 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.
J. Intrinsically safe circuits
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!
