Refreshed Knx State; Central Group Objects - ABB i-bus KNX Product Manual

ABB i-bus® KNX FUNCTION
After connection to the ABB i-bus® KNX, bus voltage recovery, ETS download or ETS reset, the device is
in KNX operation . The Manual operation LED is off.

Actuator, Page 77.
4.1.4.1 Central switch-off via membrane keypad
All outputs can be jointly switched off via the membrane keypad.
1. Select all outputs with a long button push (< 5 seconds) of the S button .
ð All zone LEDs light up.
2. Press any Output (I ... IV) button.
ð All outputs are switched off.
The first output group is selected automatically after the outputs switch off. Manual mode is exited, and
the device is in KNX operation.
When switch-off is performed via the membrane keypad, the configuration of the outputs as NC con-
tacts or NO contacts is taken into account.
NO contact:
• Relay contact open
• Status LED Off
NC contact:
• Relay contact closed
• Status LED on
If an output pair is parameterized as a Shutter Actuator, switch-off via the membrane keypad always
opens the contacts. If the blind/shutter is moving, it will be stopped.
The safety functions (weather alarms as well as the functions Safety priority , Forced operation and
Disable ) take priority over Manual operation mode. An output cannot be operated using the membrane
keypad if it is disabled by a safety function. If the safety function is canceled in Manual operation
mode, the output reacts corresponding to its parameterization.
4.1.5

Refreshed KNX state

If an output is disabled by device-specific functions (e.g. manual operation, alarms, disabling, forced op-
eration, switching delay, etc.), it will not react to telegrams received via the ABB i-bus® KNX during the
disabling.
The device processes these telegrams in the background and performs any active functions (e.g. stair-
case lighting, logic, position, brightness values, etc.) in the background as well. The current value is for-
warded to the output only when the disabling of the output is canceled.
If the output does not receive any telegrams via theABB i-bus® KNX during disabling, the output will as-
sume the state it was in before disabling.
4.1.6

Central group objects

The central group objects of the device can be used to switch several device outputs at the same time.
The following group object is available for central control of the Switch Actuator outputs:
