I n Ex applications, the regulations for the wiring of intrinsically safe
circuits must be observed.
T he indicating and adjustment modules indicates faults via error codes
and text messages. The following table describes the error codes with
status according to NE 107 and gives information on the causes of
failure and their removal:
Status accor-
ding to NE 107 Error code Text message Cause/Rectification
F ailure E 013 no measured value available S ensor in boot phase
no measured value available S ensor does not find an echo, e.g.
due to faulty installation or wrong
parameter adjustment
no measured value available W rong sensor length entered
E 017 A djustment span too small A djustment not within the specifica-
tion. Carry out the adjustment again,
increasing the distance between
min. and max. adjustment
E 036 N o operable software F ailed or interrupted software up-
date/Repeat software update
E 042 H ardware error, electronics defec-
tive
E xchange the instrument or send it
in for repair
