Engineering notes

2019-11-28

The following regulations apply to these operating voltages:

Regulation

Operating voltage
AC 24 V

The operating voltage must comply with the requirements for
SELV or PELV:

·

 

Permissible deviation of AC 24 V nominal voltage at the
actuators: +/–20 %

Operating voltage
AC 230 V

·

Permissible deviation of AC 230 V nominal voltage at the
actuators: +/–10 %

Specification on
AC 24 V
transformers

·

 

Safety isolating transformers as per EN 61 558, with double
insulation, designed for 100 % duty to supply SELV or
PELV circuits

·

 

Determine the transformer’s power consumption by adding
up the power consumption in VA for all actuators used.

·

 

The capacity used from the transformer should amount to
at least 50 % of the nominal load for efficiency reasons
(power efficiency)

·

 

The nominal capacity of the transformer must be at least
25 VA. For smaller transformers, the ratio between voltage
at idle time to voltage at full load is unsatisfactory
(> + 20 %)

Fuse of AC 24 V
operating voltage

Transformers, secondary side:

·

 

According to the effective load of all connected devices

·

 

Line G (system potential) must always be fused.

·

Where required, line G0 also (system neutral)

Fuse of AC 230 V
mains voltage

Transformers, primary side, as per the applicable installation
regulations of the respective country

4.2  Device-specific regulations

Safety for the devices is ensured by (among other aspects):

·

 

Supply of AC 24 V extra-low voltage as per

SELV

 or

PELV

·

 

Double insulation between AC 230 V mains voltage and SELV/PELV circuits

·

 

Mount max. two actuators on the same damper shaft. Use the mounting bracket to
also secure the second actuator (see powerpack-accessories in section 2.2).

Apply

only mains voltage

 or

only safety extra-low voltage

 to the switching outputs of

auxiliary switches A and B. Mixed operation is not permissible. Operation using various
phases is not permissible.

Consider the potentiometer's electric data to indicate the damper position via the
external circuit.

It is recommended to switch off the power during two-position control when the actuator
has reached the open or close position, in order to enhance life span and reduce power
consumption.

  Operating voltage

AC 24 V, AC 230 V

Device safety

Mechanical parallel
connection of actuators

Auxiliary switches A, B

 Feedback potentiometer

for position indication

2-position control
