Before connecting the unit for the first time the following points should be
checked:
Check the electrical connections are correct and secure.
Make sure you are conversant with the operation of the display before
connecting.

DIP-Switches
Description
S2/8:
off = Input data, on = Output data,
Factory default: Input data
S2/1-7:
Binary coded
Bus address [0...126],
Factory default: Bus address 4 (S2/3 = on)
S1/1-8:
Binary coded
Offset in Byte [0...244],
Factory default: No offset
The 7 lower pins (PIN1 to PIN7) of the address DIP switch (S2) specify the
user field bus address, from which the process value is to be read. The range
on PROFIBUS-PA is 0...125.
PIN8 of the address DIP switch (S2) sets if the values to be displayed are
output data (PIN8=1, e.g. actuator control) or input data (PIN8=0, e.g. sensor
process value).
Using the 8 pins of the offset DIP switch (S1) the offset is set up. The offset
indicates the point in the data telegram (on sensors with a process value = 0,
e.g. temperature sensors) where the process value is to be displayed (4 Byte
process value, 1 Byte status)starts. The range on PROFIBUS-PA is
0...245 Byte.
Factory default
1. Sensor process value in address 4
