Ease of operation
L&W Bending Tester is easy to use with a large touchscreen interface
and intuitive menus, saving operator time and effort. Operators can
quickly change settings from the screen, with correct authorization.
It provides easy calibration and simple instrument check with included
check plate and gives a quick overview of results for an entire series.
The bending curve with break angle/force in dication allows quick analysis
of the test to identify any erroneous measurements.
Operation is automated once the operator hits start. First, the instrument
is connected to power and pressurized air, and the operator selects either
a standard or pre-set, custom program. The pre cisely cut test piece can
be easily loaded in the measuring clamps and correctly aligned with the
loadcell with the help of sample support.
The operator simply places the test piece inside the clamp with one hand,
while the other hand starts operation with the ergonomically placed start
button. The clamps are automatically closed with fixed pressure for precise
measurement.
Bending length detection ensures that the bending length selected in program
settings matches the manually set bending length, or otherwise warns the
operator with an error message.
ABB’s L&W Bending Tester is an easy-to-use and reliable instrument
that measures bending resistance and stiffness of paper and board.

Even strength within specifications and across the reel width
L&W ZD Tensile Tester measures internal bond strength – or Z-direction (ZD)
tensile forces – of paper and multi-layered paper products, such as linerboard
and box board. The tester uses an automated method and you obtain fast
and reliable measurement values, which make it possible to achieve uniform
strength across the reel width. All in compliance with customer specifications,
as well as in accordance with applicable standards (ISO, TAPPI, SCAN).
Full control of the internal bond strength, is particularly important in the
production of multi-layered paper products. Low or unevenly distributed
internal bond strength can cause material splitting in an offset press with
sticky printing ink. In the creasing or scoring operation of boxboard the
material should delaminate “just enough”. Otherwise after folding there
will be poor folding lines or cracks in the outer layer. Internal bond strength
tests can predict this.
Enough internal bond strength is also needed in heat-set web offset printing
of highly coated paper. Otherwise blistering will occur when moisture will try
to escape during the heating process. Too high internal bond strength impedes
the creasing of the boxboard and high values also mean a waste of raw material
and energy. In other words, the aim is to achieve an even strength within
specifications and across the reel width. L&W ZD Tensile Tester can achieve this.
The ZDT Oxygen Analyzer is designed for continuous
monitoring of oxygen content in applications using ‘in situ’
ZGP2 probes.
Operation and programming of the ZDT Analyzer is via four
tactile membrane switches and a digital display located on the
front of the instrument. Two l.e.d.’s on the front panel provide
local alarm indication.
In operation, the instrument can display measured % oxygen,
cell mV, or cell temperature. Set up of alarm, retransmission
and calibation parameters is achieved in programming mode,
where key parameters are protected by a five-digit security
code.
Measured %O2 values can be retransmitted to remote
equipment using the retransmission output facility. The range
of values retransmitted can be set anywhere within the
instrument’s display range of 0 to 25% O2. subject to limits
detailed in Section 7.7.
Remote alarm indication is provided by two relay outputs.
Relays are programmed to activate when the oxygen level
moves either above or below a pre-defined set point. The
second alarm relay can also be used as a ‘general alarm’
which activates in the event of an instrument or system fault.
An optional external reference air unit is used to provide
reference air supply for the ZGP2 probe. If this unit is not
specified, reference air must be supplied to the probe from an
alternative source.
For full installation and operation details of the ZGP2 probe
refer to the operating manual, IM/ZGP2.
‘Fail-safe’ safety function
If the electric power supply fails, the positioner output 1 is
depressurized and the return spring in the pneumatic
actuator moves the valve to the safe position. In case of a
‘double-acting’ version, output 2 is additionally pressurized.
‘Fail-freeze’ function
If the electric power supply fails, the positioner Output 1
(and Output 2 if applicable) is closed and the pneumatic
actuator blocks the valve in the current position. If the
compressed air supply power fails, the positioner
depressurizes the actuator.
Use
The positioner has a built-in operating panel providing a 2
line LCD indicator and 4 operating buttons for
commissioning, configuration and monitoring during live
operation.
Alternatively, the appropriate configuration program can be
used via the available communication interface.
Communication
The positioner has a local communication interface (LCI) as
standard. Additionally, a ‘HART® communication’ option for
communication via the 20 mA signal is available. Both
communications are based on the HART® Protocol.
Alternatively, HART®5 or HART®7 are available.
Inputs / Outputs
In addition to its input for the analog position setpoint, the
positioner is equipped with a digital input which can be used
to activate control system functions in the device. A digital
output allows you to output collective messages (alarms /
faults).
Modular design
The basic model can be enhanced at any time by retrofitting
optional equipment.
Option modules can be installed for analog and digital
position feedback.
Additionally, a mechanical position indicator, proximity
switches or 24 V microswitches are available for indicating
the position independently of the mother board function.
Brief description
The TZIDC is an electronically configurable positioner with
communication capabilities designed for mounting on
pneumatic linear or rotary actuators. It features a small and
compact design, a modular construction, and an excellent
cost-performance ratio.
Fully automatic determination of the control parameters and
adaptation to the positioner allow for considerable time
savings as well as optimum control behavior.
Pneumatics
An I/P module with subsequent pneumatic amplifier is used
to control the pneumatic actuator. The well-proven I/P
module proportionally converts the permanent electrical
setpoint signal from the CPU into a pneumatic signal used to
adjust a 3/3-way valve.
Dosing of the air flow for pressurizing or depressurizing the
actuator is continuously adjusted. As a result, excellent
control results are achieved. When reaching the setpoint, the
3/3-way valve is closed in center position to minimize the air
consumption.
The pneumatic system can be supplied in four versions: for
single acting and double acting actuators and each with the
‘fail-safe’ / ‘fail-freeze’ safety function.
For ABB, the customer has always been the key focus of the
process chain. Therefore we would like to go a step further
in the Actuators & Positioners product line and show our
customers new possibilities within the scope of our OEM
Labeling Program that could possibly inspire them with
new ideas and incentives.
Our positioner portfolio features many different
product-related possibilities as a part of our OEM Labeling
Program. By this we understand and distinguish to and make
a distinction between ‘Labeling light’ and ‘Full labeling’.
In this brochure, we will present the different possibilities
available based on examples for the TZIDC, TZIDC-110.
TZIDC-120. EDP300 and TEIP11 types. The ‘light’ OEM
Labeling Program includes two components which the
customer can freely configure:
• Color
• Naming
COLOR
The customer can choose any color from the RAL color palette.
By providing the RAL color number, any misunderstandings
and interpretations are excluded, since the coding corre
sponds to an international standardized color tone.
Color requests beyond the RAL palette are also an option.
We will be happy to try to fill such requests in cooperation
with our suppliers. Feel free to contact us in this regard. The
customized color requests always apply to the cover for the
TEIP11. For the TZIDC, they apply to the bottom and top
parts of the housing.
For the TEIP11. the bottom parts of the housing are always
in the black color and coating system. Due to certification
specifications, we unfortunately cannot implement different
color requests on the bottom parts of the housing.
For the EDP300. the color implementation involves applying
print in a RAL color near the label names on the HMI. See the
examples below.
The solution – accurate measurements for
maximum energy efficiency
Thanks to an (innovative control algorithm taken
from the field of robotics, the EDP300 positioner
stands out thanks to its speed and accuracy.
Overshooting and slow recovery times are both
prevented, allowing the EDP300 to significantly
optimize compressed air consumption, energy
efficiency and the ʹecological footprintʹ of pneu
matic control circuits.
Subsequently, the EDP300 is able to help reduce
cost with its unique electro-pneumatic system,
providing unsurpassed low air/gas consumption
at steady state. The EDP300 can also be used in
applications with natural gas as the supply energy,
eliminating the need for compressed instrument
air. ABB is the only supplier able to offer customers
a premium positioner that features these pneu
matic properties.
