ders, with up to 12 load cells. The high level of functionality and user friendliness make the
PFEA113 one of the most complete tension electronics on the market.
Covering a wide range of applications the Tension Electronics comes in three versions (PFEA
111 and PFEA 112 are described in a separate manual), with different levels of performance and
functionality. All three versions have multi-language digital display and configuration keys. The
configuration keys being used for setting different parameters and to check the status of the
tension system. The 2 x 16 character display can present sum, difference or individual load cell
signals. All three versions are available in both DIN-rail version (IP 20-version, unsealed) and
enclosed IP 65-version (NEMA 4) for mounting in more severe environments.
The equipment is intended for use in a wide range of manufacturing processes where web
material of any kind, e.g. paper, plastic or textile, is transported in a machine. The only
requirement is that the web is wrapped over a roll. The force on the roll is proportional to the
web tension. The resulting force is transferred through the bearing housings into the load cells.
The load cells create a signal that is proportional to the force acting in the measuring direction
of the load cells. This signal is processed and amplified in the tension electronics and can be
used as an input signal for process control, presentation on a display or for registration.

1.6 Safety Instructions
Read and follow the safety instructions given in this section before starting any work. However,
local statutory regulations, if stricter, are to take precedence.
The tension measurement system contains no moving parts. However, the load cells are
mounted close to a rotating roll over which a web is running.
1.6.1 Personnel Safety
WARNING
Never work with the load cells, or nearby, when the production line is in service.
Before starting any work, switch off and lock the operating switch of the drive
section for the measuring roll.
DANGER
Switch off and lock the mains operating switch to the tension electronics before
performing any work on the tension electronics. When the work is completed,
check that there are no loose wires, and that all units are properly secured.
NOTE
All personnel working with the installation must know the location of the main
power supply switch to the measurement system and how it is operated.
1.6.2 Equipment Safety
CAUTION
Always switch off the mains supply voltage to the measurement system before
replacing a unit.
CAUTION
Handle the electronic unit carefully to reduce the risk of damage from
Electric Static Discharge (ESD). Note the warning label on the circuit boards.

1.7 The Measuring Technique Based on Pressductor® Technology
The operating principle of a force transducer has a great effect on how well it will perform. It
also affects how stiff and vibration-free the entire load cell will be, as well as its robustness and
tolerance to overload. All of these factors impact on the design, operation, and maintenance of
the web processing machinery.
ABB’s Pressductor® transducer technology produces a signal as a result of changes in an
electromagnetic field when the load cell is subjected to mechanical force. It is an operating
principle that has its origin in a metallurgical phenomenon according to which mechanical
forces alter the ability of som
