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.

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” indication is red. Use the to step to the last
operator menu, where you can read the error or warning message.
6.6.1 Error Messages
The following errors can be detected:
• Flash (memory) error
• EEPROM (memory) error
• Supply error
• Load cell excitation error
See Section 6.8 Warnings and Errors Detected by the Tension Electronics.
6.6.2 Warning Messages
The following warnings can be detected:
• Profibus communication problem
• Synchronization problem
See Section 6.8 Warnings and Errors Detected by the Tension Electronics.

6.7 Fault Symptoms and Measures
General remark:
If the free (unscreened) cable length exceeds 0.1 m (4 in.) the individual pairs of power and
signal conductors must be twisted.
Free length exceeding 0.1 m can cause unstable zero point or incorrect absolute measurement
value.
Table 6-1. Fault Symptoms and Measures
Fault symptom Measures
Noisy signals - Check that cable shields are connected to earth
according to cable diagram.
- Proximity to noisy cables can cause interference
problems.
Unstable zero point - Check that cable screens are not connected at
both ends.
- Check that cable between load cell and electronic
has diagonal pairs, one pair for signal circuit and
one pair for excitation circuit, see Figure 2-2.
- If a junction box is installed, check that load cell
signal and load cell excitation between junction
box and electronics are routed in separate cables.
- Check, if two or more IP 20 units are mounted
close to each other in the same cabinet, that they
are synchronized (cable for synchronizing the
units, see cable diagram and Section 2.4.1.3
Synchronization).
Display and LED indictors are
not illuminated
If the Operator panel display is not illuminated and
the “Power” and “Status” indications are on and the
Operator Panel is “OFF”, check the following:
- Check that the cables are correctly connected to
the electronics power supply.
- Check that the power supply connected to the
electronics is correct.
- Check that the power switch is “ON” (inside the
IP 65-version (NEMA 4) enclosure).
