Switch Actuator with Secure
1
Chapter 1. Summary
Switch Actuator with Secure is mainly applied in building control system, connected to the BUS via
KNX terminals and installed together with other devices on the bus to become a system. These switch
actuators can be used to control the switch loads, such as:
Lighting
Heating control
Signal devices
It is able to switch from 4 to 12 independent electrical AC loads or three-phase loads by the switch
actuators with maximum output of 16A or 20A per output and manual switch, as well as visible
switching status.
Note
：
The database files ARSA-xx/20.S are the same with ARSA-xx/16.S. Their main difference is
that the size of the load is not same.
Switch Actuator with Secure is modular installation devices in proM design, which are easy to
install in the distribution boards on 35mm mounting rails according to EN60715. The devices connect
to KNX system via bus connection terminal, and no additional power supply voltage is required. It is
able to use the Engineering Tool Software ETS (ETS5 or later) with knxprod file to allocate the physical
address and set the parameters.
This manual provides you the detailed technical information about the Switch Actuator with Secure,
not only the installation and programming details, but also the usage explanation in actual application.
There are same following programming functions for each output:
Manual operation available
Time function: on/off delay
Staircase function with the warning and adjustable staircase lighting time
Scene, preset control: 8bit/1bit
Logic operation: AND, OR, XOR, gate function
Status response
Forced operation and safety function
Threshold function setup
Control of electric thermal valve function
Selection of preferred status after bus voltage failure and recovery
