12 KNX information
12.1 Reset and startup response
A reset is initiated under the following circumstances:
Failure of the processor (e.g. watchdog).
After a power failure.
After a bus power failure.
Upon completion of a self test (using communication object Status request).
Via ETS (without startup delay)
– After downloading the physical address
– After downloading the parameters
– Via ETS (menu
Commissioning, Reset).
After parameterization in ACS.
After exiting Parameterization mode in the HandyTool.
After Test with the HandyTool
The application is restarted after every reset. Depending on the controller address, this
may take 1 ... 255 s.
Then, the bus connection is opened and all connected valve actuators are
synchronized. This takes the following time depending on application and actuator type:
Typically 170 s for closing (runtime + 10%) for motorized actuators.
300 s ON and 300 s OFF (3rd party: 400 + 400 s) for thermal actuators.
The application is placed in a safe state. Any outputs that are not synchronized are not
operated (triac outputs = 0, and relay = open).
Normal operation is resumed after synchronization.
When the controller exits test mode, only a soft reset is carried out:
– Valve actuators are synchronized.
– The control algorithm but not the entire application is restarted.
Each time the control sequence reaches 0% or 100%, a limit position
synchronization takes place.
– For motorized actuators close or open during (runtime + 10%).
– 300 s ON and 300 s OFF (3rd party: 400 s) for thermal actuators.
12.2 LED flashing pattern
An LED is located at the controller's bottom right indicating the operating state by
various flashing patterns:
Green, flashing Normal operation.
Red, flashing Programming mode for address assignment (ETS3 / ACS).
Orange / green,
flashing
Startup phase (see above 12.1).
No application selected (see 4.1).
Loading.
– Download from ETS3 or ACS.
– Room unit QAX34.3 in HandyTool mode.
Other patterns After switching on the operating voltage, the controller flashes for 3
to 5 seconds in different patterns.
If other patterns appear during normal operation, this indicates an
error.
