This chapter contains the information needed to commission a Web Tension System.
It is assumed that the Web Tension System has been installed according to the instructions given
in
Chapter 2 Installation
and
type.
You must have the following data before starting commissioning:
1.
Load cell type and nominal load, see Appendix for installed load cell type
2.
System definition, see
•
Load cell combination
–
One roll (load cells A and B)
–
Two rolls (Roll 1 connected to A and B, Roll 2 connected to C and D) or
–
Segmented roll
•
Gain scheduling (switching wrap gain for two different web paths).
–
One roll, Two rolls (only Roll 1) and Segmented roll.
3.
Object type, see
Section 3.12.3.
•
Standard roll (Roll 1, load cells A and B or Roll 2, load cells C and D)
•
Single side measurement (Roll 1, load cell A or B and Roll 2, load cell C or D)
•
Segmented roll
Up to 12 load cells connected to max. three PFEA113 can be handled. The load cell inputs
must be connected to PFEA113 as follows:
- One input, load cell connected to A
- Two inputs, load cells connected to A and B
- Three inputs, load cells connected to A, B and C
- Four inputs, load cells connected to A, B, C and D
4.
Desired output data at given web tension
5.
Communication data, see
Read and follow the safety instructions described in
commissioning work. However, local statutory regulations, if stricter, are to take precedence.
The following items are required:
•
Cable diagram
•
Service tools
