ABB DI610 digital input and output unit
Insulation Amplifier PXUB 201 (only for the IP 20-version)Insulation amplifier PXUB 201 is used when galvanic insulation between input and output, or
between power supply and input/output, is required. See Section A.5.1 Insulation Amplifier
PXUB 201.
Insulation amplifier PXUB 201 is intended to be installed on a DIN-rail. The PXUB 201 is
connected by screw terminals.
PXUB 201 is normally supplied from the same +24 V DC supply that supplies the tension
electronics.
If PXUB 201 is mounted close to the terminal group, it is not necessary for the cable between
the tension electronics and PXUB 201 to be screened.

2.8.2 Power Supply Unit SD83x
If no 24 V is available, the power supply units SD 831, SD 832 and SD 833 can be used as
power supply for the IP 20-versions.
The power supply unit is intended to be installed on a DIN-rail.
The main supply voltage for all the three power supply units are:
• 115 V AC (90 - 132 V), 100 V -10% to 120 V + 10%
• 230 V AC (180 - 264 V), 200 V -10% to 240 V + 10%

About this Chapter
This chapter contains necessary information for commissioning your Web Tension System.
It is assumed that the Web Tension System has been installed according to the instructions given
in Chapter 2 Installation and Appendix (B, C, D, E, F or G) depending on installed load cell
type.
You must know the following data before starting commissioning:
1. Load cell type and nominal load, see Appendix for installed load cell type
2. Object type, see Section 3.12.2
– Standard roll (two load cells)
– Single side measurement (one load cell)
3. Maximum web tension
4. Desired output data at given web tension
5. Communication data, see Section 3.13
3.2 Safety Instructions
Read and follow the safety instructions stated in Chapter 1 Introduction, before starting any
commissioning work. However, local statutory regulations, if stricter, are to take precedence.
3.3 Necessary Equipment and Documentation
The following items are required:
• Cable diagram
• Service tools
Navigating and Confirming
3.4.2 Changing Numerical Values and Parameters
• X indicates a numerical value.
• Z indicates that a parameter can be chosen from a list.
To change a numerical value, X, or parameter, Z, press . The numerical value or parameter is
then placed within brackets [XXXXXX] or [ZZ] to show that it can be changed.
If it is a “Z” parameter, use and to go up or down in the list. When the desired value is
shown on the display press . When is pressed the new parameter value is saved and the
brackets around the value disappear.
If you have pressed so that the parameter is placed within brackets, you can cancel the
entering mode by pressing . The selections you have done with and will not be
stored. If is pressed the old value is displayed without brackets.
To change a numerical value, press so that the value is placed within brackets. Then the first
digit can be changed with and . When the first digit has the desired value press , then
the second digit can be changed with and . When pressing after the last digit has
been set, the new value is saved and displayed without brackets.
Using when entering a numerical value means returning to the previous digit. By pressing
a sufficient number of times you will leave the entering mode and the old value will be
displayed without brackets.
