1.4.1 Getting Started
You can use the Fast Setup sequence to set up your system for basic measurement.
The Fast Setup guides you through a minimum number of steps to set up the tension electronics.
Perform the actions in the following sections:
• Section 3.6 Step-by-step Commissioning Guide
• Section 3.7 Performing Basic Settings
• Section 3.8 Performing a Fast Setup
For extended functionality, use “Performing a Complete Setup”.
See Section 3.11 Performing a Complete Setup.
1.4.2 Saving Actual Data and Settings at Commissioning
When commissioning is completed you can use the form in Appendix H, where actual
commissioning data and settings can be filled in and saved for future use.

About this System
Your system for tension measurement consists of:
• Tension Electronics PFEA111 or PFEA112
– PFEA111 is a cost effective compact and user friendly tension electronics providing
an accurate and reliable fast analog SUM signal from two load cells for control
and/or monitoring. The display can show the SUM, individual A & B and difference
signal. The small size and DIN-rail mount make this unit very easy to integrate into
many types of electrical cabinets
– PFEA112 provides the same functionality and user friendliness as the PFEA111 with
the addition of fieldbus communication via Profibus-DP.
Covering a wide range of applications the Tension Electronics comes in three versions
(The PFEA 113 is 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.
• Load cells of type PFCL 201, PFCL 301E, PFTL 101, PFTL 201, PFTL 301E and PFRL
101
The equipment is intended for use in a wide range of manufacturing processes where a web of
any kind of material, 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.
