To accept the values set on the DIP switches, the device must be isolated briefly from
power supply.

The address 0 is set on the device when delivered. Care should be taken that no
address is assigned more than once.
The device has three LEDs, located on the front of the housing.
The meaning of these LEDs is given in the following table:
Color Meaning
Red Error indications (detected during the initialization phase)
Green Operating indications
Orange HART communication with a field device
During the initialization phase, the green LED flashes, the other two are off.
During the REBUILD function, the green LED is ON and the orange flashes.
If all three LEDs flash one after the other, the DIP switch 1 (test) is in the ON
position. Set the switch to OFF and repeat the commissioning.
Following connection of the power supply, the device executes an initialization
procedure with self test. The function is indicated by a flashing green LED, any errors
detected are indicated by a red LED. Next a search is made of the Multiplexers in the
Multiplexer table (command 157) for available HART compatible field devices
(REBUILD). This function is indicated by a flashing orange LED. The REBUILD
function can also be started via the service station, e. g. in order to include
connected transmitters in the communication process during the operating phase.
The duration of this function is dependent on the number of connected transmitters,
Multiplexer Slaves and message repeats in the case of errors, or if an interrogation
has not been answered. The factory setting for the number of repeats is 2. The
search duration for this lies between approx. 30 s and several minutes (full
structure).
After finishing this phase the orange LED should be expired.
In addition, transient data are set to their pre-setting. Non-volatile stored data are
retained. see section 5.4.5.
