LED Colour Assignments
21 LED COLOUR ASSIGNMENTS
The switching statuses of the process valves as well as the device statuses are signalled to the outside via
thecentralmulti-colourstatusdisplay(devicestatusLED/TopLED),sothatquickvisualcontrolispossible
also for large systems.
Coloursandashingpatternshavebeenassignedtothesignalsoftheprocessvalvepositionsanddevice
statuses – see chapter “21.1.1DevicespecicLEDmode“8681ClassicMode”” and “21.2 Flashing pattern &
faultsignalling”.Whenseveralsignalsareoverlapped,aprioritylistapplies(“21.3Signalpriorities”).
In order to be able to react to various process valve designs or customer signalling philosophies in the systems,
the colour assignments can be changed on site using the DIP switches for colour coding
(see chapter “21.1.1
DevicespecicLEDmode“8681ClassicMode”” – except for the IO-Link version, which does not have DIP
switches).
For the büS/CANopen and IO-Link variants,thecolourscanalternativelybeassignedusingtheBürkert
Communicator. With the DeviceNet, büS/CANopen and IO-Link variants, changes to settings can also be
carriedoutviatheactualbus-speciccommunicationinterface;inthiscase,nosettingsontheelectronic
modulearerequiredand,assuch,thecovercanremainclosed.
Factory setting DIP 1 - 4: 0000 – i.e. DIP1to4inposition0=OFF
(relatestovariants24VDC,120VAC,AS-i,DeviceNet)
Factory setting DIP 1 - 5: 111110 – i.e. DIP1 to 5 in position 1 = ON,  DIP 6 = Pos. 0 = OFF
(relatestovariantbüS/CANopen-see following chapter “21.1”)
When using the control head in a potentially explosive atmosphere, the housing may only be
opened in a not energised state.
8 DIP switches
for setting the
baudrate
and address
(forDeviceNet
and büS/
CANopenonly)
4 DIP switches
for colour coding
PositionON=1
PositionOFF=0
