ExMax-...-F3
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 or
line 3 opened. 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.
Integrated auxiliary switches signal the rotation angle's position. U
the switches were operated with higher voltage or current.

Functions, adjustments and parameters
PA A) Self adjustment of angle of rotation
ATTENTION: To adjust the angle of rotation connect only wire 1 and 2.
Do not connect wire 3.
Apply supply voltage to wire 1 and 2. Turn switch (S) to position 02. Press
button (T) for a minimum of 3 seconds. The actuator drives to the first end posi-
SB 3.2
tion, detects the blocking position and performs a spring return to the starting posi-
tion. The LED flashes GREEN during adjustment. After that disconnect from the
mains and connect wire 3.
The adjustment takes about 93 seconds (90 sec. "On", 3 sec. "Off").
B) Selecting motor running time
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 opera-
tion.
C) Function of the ExPro-TT-... in the Ex-i tripping circuit
When the ...Pro-TT's tripping circuit is opened the actuator runs into its end posi-
tion with spring return.
D) Additional information for control in On-off operation

The rotation direction (clockwise / counter clockwise) depends on left / right
