Safety notes

!

•  This actuator has been designed for application in stationary heating, ventilation and 

air-conditioning systems and is not allowed to be used outside the specified field of 

application, especially not in aircraft or in any other airborne means of transport.

•  Only authorised specialists may carry out installation. All applicable legal or 

institutional installation regulations must be complied with during installation.

•  The switch for changing the direction of motion/the closing point may be adjusted 

only by authorised personnel. The direction of stroke is critical, particularly in 

connection with frost protection circuits.

•  The device may only be opened at the manufacturer's site. It does not contain any 

parts that can be replaced or repaired by the user.

•  The cable must not be removed from the device.
•  The device contains electrical and electronic components and is not allowed to be 

disposed of as household refuse. All locally valid regulations and requirements must 

be observed.

Product features

Principle of operation

The actuator is equipped with an integrated interface for LONWORKS®. The actuator 

can be integrated and connected directly with LONWORKS® via transceiver FTT-10A.

Interrupting the supply voltage causes the valve to be moved to the selected 

emergency setting position (POP) by means of stored electrical energy.

Pre-charging time (start up)

The capacitor actuators require a pre-charging time. This time is used for charging the 

capacitors up to a usable voltage level. This ensures that, in the event of an electricity 

interruption, the actuator can move at any time from its current position into the preset 

emergency setting position (POP).

The duration of the pre-charging time depends mainly on the following factors:

– 

Duration of the voltage interruption

– 

PF delay time (bridging time)
