Process error messages

Process errors can be defined as either "Fault" or "Notice" messages and can thereby
be weighted differently. This is specified via the function matrix (→ Page 92)
Typ Error message / No.
e
P = Process error
$
= Fault message (with an effect on the inputs and outputs)
! = Notice message (without an effect on the inputs and outputs)
P EMPTY PIPE
#401
!
P ADJ. N. OK
! # 461
P EPD FULL = EMPTY
! # 463
Cause
Positive zero return active.
"
Caution!
This message has the highest
display priority.
Simulation of failsafe mode
(outputs) active
Simulation of volume flow active
Cause
Measuring tube partially filled or
empty
EPD adjustment is not possible
as the fluid conductivity is too
low or too high.
The EPD adjustment values for
empty pipe or full pipe are
identical, i.e. faulty.
9 Trouble-shooting
Remedy / spare part
Switch off positive zero return
Switch off simulation
Switch off simulation
Remedy
1. Check system process
conditions
2. Fill measuring tube
The EPD function cannot be
used for such fluids!
Repeat adjustment and follow
procedure
