ExMax-...-Y
Special option
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 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.

Switch position 07
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. 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
PA
▪ Complete pushing (3 ×) within 5 sec.
LED – Status:
▪ GREEN (permanent)
▪ 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
b closed, a open
a and b closed
a and b opened
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.
During commissioning apply a self adjustment drive.
Regard duty cycle at motor running times !
Never use spring return actuators without external load.
