number and is received from
E+H with order of S package)
– S package upgrade:
code received from E+H
⇒

first enter instrument serial
number (s. nameplate) manually,
then enter code
Detailed description see chpt. 8.5.5
No HART
communication
– No central HART module Verify by looking at nameplate:
HART = -xxx5xx and -xxx6xx Upgrade to LSCH-H1 / -H2
– No or wrong DD
(device description)
For further information see chpt. 6,

– HART interface missing
– Instrument not registered with
HART server
– Load < 230
Ω
– HART receiver (e.g. FXA 191) not
connected via load
– Incorrect device address
(addr. = 0 for single operation,
addr. > 0 for multi-drop operation)
– Line capacitance too high
– Line interference
No Profibus PA
communication
– No central PA module Verify by looking at nameplate:
Profibus PA = -xxx3xx Upgrade to LSCP module
– Wrong SW version (without PA)
For further information see chpt. 6,

– Commuwin (CW) II:
CW II version and instrument
SW version incompatible
– No or wrong DD/DLL
– Incorrect baud rate setting for
segment coupler in DPV-1 server
– Incorrect station (master)
address or duplicate address
– Incorrect station (slave) address
– Bus line not terminated
– Line problems (too long, cross
section too small;
not shielded, screen not
grounded, wires not twisted)
– Bus voltage too low (bus supply
voltage typ. 24 V DC for non-Ex,
13.5 V DC for Ex)
Voltage at instrument PA
connector must be at least 9 V.
