Manual Operation - ABB i-bus KNX Product Manual

ABB i-bus® KNX FUNCTION
The function Forced operation is set in the parameter Forced operation (1 bit / 2 bit).
When forced operation is canceled, the output's switching position is defined in the parameter Switch-
ing state on cancellation of disabling, forced operation and safety priority and operation is enabled.
Example:
The function Forced operation can be used to ensure that all lighting systems are switched on during a
fire alarm and secured against being unintentionally switched off.
4.1.3.2.4 Priority of safety functions
The safety functions Safety priority x , Disable and Forced operation have priority over every other func-
tion.
If one of these functions is active, operation of the corresponding output is disabled.
The order of priority of the safety functions cannot be changed, → Priorities, Page 98.
4.1.4

Manual operation

NOTICE
The bus voltage supply must be established to operate the device in Manual operation mode.
Manual operation is ended in the event of bus voltage failure. The reaction of outputs to bus voltage
failure can be set in the ETS application:
Shutter Actuator → Reaction on bus voltage failure, Page 136
Switch Actuator → Reaction on bus voltage failure, Page 195
Manual operation mode permits on-site operation of the device using a membrane keypad.
The relays of the outputs can be switched manually. The relay switching states or the shutter movement
position is additionally displayed in accordance with the selected output function.
The relay status is indicated in groups of four consecutive switching outputs or two consecutive shutter
outputs. A mixture of switching and shutter outputs is possible, e.g. two switching outputs and one
shutter output.
Depending on the parameterization as a switching output or shutter output, each relay can be operated
individually as a switching output or two relays can be operated together as a shutter output. Definition
of Switch Actuator or Shutter Actuator mode is possible exclusively via parameterization in ETS.
In the as-delivered state, all outputs of the device are parameterized for operation as a Shutter Actuator.
Manual operation is enabled and can be activated via the S button on the membrane keypad.
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.
When manual operation is active, the outputs will continue to react to KNX commands until they are
switched via manual operation. If an output has been switched via manual operation, incoming KNX
commands will be processed in the background and no longer executed until manual operation is de-
activated.
