Solar protection actuator
JB520C23
5WG1520-4CB23
April 2020 / Page 1
Product and Applications Description
The JB520C23 solar protection actuator is a KNX device with
one relay output. The device is installed in a 4 x 4 inch junc-
tion box. The bus is connected via a bus terminal block. The
actuator electronics are supplied via the bus voltage.
The JB520C23 may be used to control blinds, shutters, awn-
ings, windows, or doors.
The device is designed to drive (per channel) one AC 120V
drive (motor) with electromechanical limit switches or with
integrated electronics for disconnection at the limit positions.
For drives with electromechanical limit switches the actuator
can be configured to detect the status of the electromechan-
ical limit switches such that the travel time between the end
positions can be measured via a synchronization run. The
travel time of the blind / shutter is automatically measured
from the upper end position to the lower end position and
vice versa. The measurement is only reliable for drives with
electromechanical limit switches. The travel time cannot be
automatically adjusted for drives with integrated electronics
for disconnection at the limit positions. These drives have to
be controlled via a time limit. Their travel times have to be
manually measured as precisely as possible and configured in
the application program.
Parallel operation of several drives on one channel requires
using a special separation relay. If such a separation relay is
connected to the output to drive several drives in parallel,
then the travel time has to be configured manually.
If the device is configured for automatic detection of the
travel time, then parallel operation of several drives with elec-
tromechanical limit switches or mixed operation with drives
with integrated electronics for disconnection at the limit po-
sitions is not permitted.
