13 KNX information
13.1 Reset and startup response
A reset is initiated under the following circumstances:
• Processor failure(e.g. watchdog).
• After a power failure.
• After a bus power failure.
• Upon completion of a self test (using the communication object "StatusRequest").
• Via ETS (without a startup delay):
– After the download of the physical address.
– After the download of the parameters.
– Via ETS (menu Commissioning, Reset).
• After parameter setting in ACS.
• After leaving the parameter setting 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 and DC 0...10 V outputs = 0, and relays = open).
Normal operation is resumed after synchronization.
When the controller exits the test mode, only a soft reset is carried out:
– The control algorithm, but not the complete application, is restarted.
– The 3-position valve and damper actuators are synchronized.
• 3-position actuators: Each time the control sequence reaches 0% or 100%, a limit
position synchronization takes place:
– For motorized actuators close or open during (runtime + 10%).
– For thermal actuators 300 s ON and 300 s OFF (3rd party: 400 s).
13.2 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 (ETS / ACS).
Orange / green,
flashing
• Startup phase (see above 13.1)
• No application selected (see 4.1).
• Loading.
– Download from ETS 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.
