During the working life of your measurement system, events may occur that disturb it and your
process. These disturbances may appear in many different ways and the reason for the fault can
be difficult to find. However, disturbances similar in character can be grouped together and
usually they have the same or similar sources of error.
The fault-tracing instructions in this chapter will help you to quickly find and correct the most
common faults.
6.2 Safety Instructions
Read and follow the safety instructions given in Chapter 1 Introduction when tracing faults.
However, local statutory regulations, if stricter, are to take precedence.
6.3 Interchangeability
6.4 Necessary Equipment and Documentation
The following items are required to perform fault-tracing and repairs:
• Cable diagrams, see Appendix (B, C, D, E, F or G) for installed load cell type
• Service tools
• Torque wrench
• Multimeter
Unit Measures
Tension Electronics The tension electronics PFEA113 is interchangeable
with a tension electronics of the same type.
A new setup is required.
Load cells The load cells are directly interchangeable
with other load cells of the same type.
Zero setting PFEA113 and resetting “Maximum
Load A”, “Maximum Load B”, “Maximum Load C” or
“Maximum Load D” are required after a load cell has
been replaced.

6.5 Fault-tracing Procedure
Faults in the... Fault symptoms
Mechanical installation Faults in the mechanical installation usually manifest
themselves as an unstable zero point or incorrect
sensitivity.
If a fault is associated with a process parameter, such
as the temperature, or can be linked with a particular
operation, the fault is likely to emanate from the
mechanical part of the installation.
Load cells Calibration data for a load cell does not change
gradually. A load cell, depending on its size and type,
can withstand up to five times(1) the nominal load in
the measuring direction. An event in the process line,
such as web breakage, may cause an overloading
large enough to alter load cell data. Depending on the
amount of overload, it may be sufficient to zero set.
(1) Read more about the overload capacity for your load cell type in Appendix B, C, D, E, F or G.
Cabling Problems such as malfunctions or unstable zero point
may arise from faulty cables or wiring.
Proximity to noisy cables may cause interference
problems.
Incorrect installation, such as cable cores connected
asymmetrically or screens earthed at both ends
instead of only at one end, may show up as an
unstable zero point.
If the polarity of load cell signals is not correct,
the cabling has to be checked.
Tension Electronics Intermittent loss of a function is usually due to a fault
in the tension electronics.
Instability problems seldom originate from the tension
electronics.
Faults in devices connected to the tension electronics
may affect its operation.

Section 6.6 Error and Warning Messages in PFEA113
3BSE029382R0101 Rev C 6-3
6.6 Error and Warning Messages in PFEA113
An ERROR is something that causes the electronics to function incorrectly.
A WARNING is something that might affect the accuracy of the measurement.
When a warning or an error occurs, a warning or an error message is displayed on the
Operator Panel and the “Status” indication turns from green to red.
When is pressed the message disappears from the display.
If the problem that activated the warning or error message has disappeared the
“Status” indication turns to green.
If the error or warning remains the “Status” ind
