The actual procedure for commissioning a load cell is simple, provided that the load cells and
cables have been properly installed. Commissioning of the control unit is described in the relevant
chapter of the control unit manual.
Check the following:
• that the load cells have been correctly installed and aligned
• that all screws have been tightened to the correct torque
• that all cables are correctly installed and connected
• that all connectors are plugged in
4.2 Preparatory Calculations
To be able to set the correct measuring range, the measurement force per load cell FR/2 at maximum tension T must be calculated. Each load cell is subjected to half the total measurement force
FR. This calculation must be done before commissioning can begin. Calculation of FR is described
in 2.5 Mounting Arrangement.

Maintenance
5.1 General
Web/strip Tensiometer Systems with Pressductor® load cells are extremely reliable and do not
require daily servicing. As a preventive measure, checks should be done periodically on all parts
subject to mechanical wear.
5.2 Preventive Maintenance
Check mounting screws and tighten if necessary.
The gaps between load cell and plates should be checked to ensure that they do not get clogged
with dirt, causing shunt force past the load cell. Clean the gaps with compressed air if necessary.
The cable between the load cell and the junction box is subjected to possible damage and should
be checked and replaced if necessary.
5.3 Spare Parts
Users are recommended to keep the following spare parts in stock:
• One load cell of correct type and size.
• One connector complete with cable (for PTFL 101A and PFTL 101B).

Fault Tracing
6.1 General
It is important to be thoroughly familiar with the description of operation in
2 Description before starting fault tracing.
6.2 Interchangeability
The load cells are factory calibrated and can be replaced directly with another load cell of the same
type. The only adjustment required after load cell replacement is zero adjustment in the control
unit.
6.3 Fault Tracing Procedure
The measuring equipment can be divided into four parts:
• The mechanical installation.
• The load cell.
• The junction boxes and the cabling.
• The control unit (see the control unit manual).
The fault symptoms indicate in which part the fault lies.
• Faults in the mechanical installation often result in an unstable zero point or incorrect sensitivity.
If a fault follows something else in the process, such as temperature, or can be linked
to a particular operation, it probably originates from something in the mechanical installation.
• Load cells are extremely robust and can withstand five times their nominal load in the measuring direction. If a load cell has nevertheless been so overloaded that its data have been
altered, this is probably due to an event in the mill, such as web/strip breakage. On excessive overload the first thing that happens is that the zero point shifts.
• Problems such as interference or unstable zero point may be caused by wiring faults. Some
malfunctions may be due to the proximity of cables that cause interference. Incorrect installation, such as imbalance in a cable or screens earthed at more than one end may cause the
zero point to become unstable. Cables are subject to mechanical wear, and should be
checked regularly. The junction box should also be checked, especially if it is subject to
vibration.
• A fault in the control unit usually causes intermittent loss of a function. It is unusual for the
control unit to cause stability problems. Faults in connected units may affect the operation of
the control unit. For further details see the control unit manual.

6.4 Fault Tracing in the Mechanical Installation
There are a number of parts in the mechanical arrangement that can cause faults. The extent to
which these faults are repeatable differs. Possible causes fall into the following groups.
• Defective mounting surface or adapter plates.
• Force shunting.
• (nsufficient mounting of load cell and adapter plates.
• Rolls and bearings.
• Driven roll.
