2 Product Specification
Geared down by helical gears, the rotary motion of the reversible motor is
transmitted to the actuator shaft, thus serving to move the connected fittings.
Integrated slow-down limit position switches turn the motor off as soon as the set
point of the slow-down limit position switch is reached.

• If the control voltage is applied to terminal 2 the actuator shaft will turn clockwise.
• If the control voltage is applied to terminal 3 the actuator shaft will move anti-clockwise.
2.4 Functions
2.4.1 Set time
The time in which the actuator shaft covers a distance of 90 degrees is called set
time. Set time is specified in s/90°.
2.4.2 Manual operating
In manual mode you can change the rotary motion manually without supply
voltage.
• In manual mode the supply voltage needs to be turned off by qualified staff.
6.1 Changing between manual and automatic mode on page 24
2.4.3 Potential-free path switch (accessory)
The optional path switch allows you (106) to set two actuating positions within
which a potential-free contact is opened or closed.
5.2 Setting the potential-free path switches on page 21
2.4.4 Potentiometer (accessories)
The optional potentiometer (180) indicates the actual position of the rotary
actuator. 0° Angles of rotation up to 90° are issued as:
•0 ... 200 Ohm
•0 ... 1 k Ohm
•0 ... 10 k Ohm
5.3 Setting a potentiometer on page 22
2.4.5 Servo actuator heater (accessories)
The optional actuator heating (190) prevents the formation of condensation inside
the actuator and ensures at the same time the ease of movement for the gear
even at temperatures up to c. -20°C.
Heating capacity:
•25 VA

5.1 Setting a limit position switch
You need to set the limit position switch before you can take the rotary actuator
into operation. Set the two limit position switches separately. Try out the sequence
of operations for each limit position switch once.
ATTENTION
Risk of damage from incorrectly set limit position switches
The limit position switches WE 1 and WE 2 turn off the motor in a path-dependant
way.
Do not change the factory setting if the actuator is delivered together with the flap.
•If actuator and flap are delivered separately, set the limit position switches WE
1 (direction of rotation clockwise) and WE 2 (direction of rotation anti-
clockwise).
Hint: The cam disks (45.1) to (45.4) inside the cam block (40) can be adjusted
separately. The pairs of screws are allocated to each cam ring by height.
