Description size S
The new RedMax actuators are a revolution for safety, fire 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 EEx-areas zone 2 (gas) and
zone 22 (dust).
Highest protection class (ATEX) and IP 66 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. 5 motor running times and 2 torques as
well as 2 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 to 230 VAC / DC.
The actuators are 100% overload protected and self locking.
RedMax-...-BF actuators are equipped with spring return fail safe function,
with integrated aux. switches for end position indication and an intrinsic
safe circuit to connect an external passive potential free thermostat.
Standard shaft connection is a double squared direct coupling with
12 x 12 mm.
Different accessories are available to adapt aux. switches, terminal
boxes or adaptations for ball valves and throttle valves.

Electrical connection
RedMax actuators are equipped with a universal supply unit working at a voltage range
from 24 to 230 VAC/DC. The supply unit is self adjustable 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 t erminal box, certificated in acc. with
ATEX is required (e.g. RedBox).

for adjustment,
behind the blancking plug
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.
Adjusmtent time needs approx. 60 sec. (30 sec. On, 30 sec. Off). After that, switch S
into position 00-09 in 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 7.0/7.1).
D) 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
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 terminal 3 and 4.
E) Function of a passive sensor in the EEx-i circuit:
If the sensor opens the EEx-i circuit the actuator runs into its safety end-position with
spring return
Mounting instructions and important information for operation and installation
EXPLOSIONPROOF
Important information for installation and operation
A. Installation, commissioning, maintenance
The cable of the actuator must be installed in a fixed position and protected against
mechanical and thermical damage. In acc. with operation RedMax actuators are
maintenance free. Nevertheless maintenace must comply with regional standards,
rules and regulations. The actuators must not be opened by the customer. For outdoor
installation a protective housing against rain, snow and sun should be applied to the
actuator, as well as a constant supply at terminal 1 and 2 for the integral heater. For
electrical connection inside hazardous areas an terminal box is requested (e.g. type
RedBox).
Example: you have to cut the supply voltage before opening an EEx-e terminal box
B. Shaft connection, selection of running time, heater
RedMax actuators are equipped with a direct coupling double squared shaft connection
of 12 x 12 mm. For round shafts an adaptor is available (Accessory type KB-S).
The housing of the actuator is axially symmetrically built to select open/close direction
of the spring return function by left/right mounting.
In acc. to the actuator type 5 different motor running times and 2 different spring return
running times can be selscted on site. The integral heater is for ambient temperatures
down to -40°C.
C. Working with 3 sec. motor running time
See extra information EL.
D. 3-pos control mode
See extra information EL.
E. Spring return
Spring return function works if the supply voltage (terminal 1 or 2) is cut. In the event
of an electrical interruption, the spring returns to its end position.
F. Operation at an ambient temperature below - 20°C
See extra information EL.
G. Excess temperature
In acc. to the ATEX rules and regulations EEx actuators must be protected against
excess temperature. An internal thermostat guarantees the temperature class in the
event of failure. If this thermostat is working the actuator must be sent to the factory.
RedMax actuators are equipped with an additional temperature sensor to stop the
actuator before reaching this max. temperature. In this case the failure must be
eliminated immediately on site.

Mounting of quarter turn valves
Details see extra information ME.
EEx-i safety temperature sensor - FireSafe
The safety thermostat type FireSafe is passive and
potential free for use in intrinsic safe circuits, directly
connectable to the EEx-i circuit of the RedMax-...-BF
actuators. The sensor switches at an ambient temperature
of 72°C and starts the fail safe spring return function of
the actuator. Sensor with manufacturer certificate in acc.
with ATEX.
RedSwitch is an accessory to RedMax actuators size
S, fixing directly onto the actuator. RedSwitch are aux.
switches with with 2 potential free contacts, adustable
on site. The electrical wiring needs an terminal box.
Important information for routine test
For periodic inspection of fire dampers cut of the the supply line (cut off the current
of the actuator)
The switch contact on FireSafe is only for test aims of actuators function.
RedBox - adaptable terminal box
For electrical connection of an RedMax inside the hazar
dous area an terminal box is required.
RedBox-BF for RedMax-5.10-BF and RedMax-15-BF.
To adapt the RedBox direct to the actuator housing an
additional accessory type MKK-S is required.
