1-8 3BOperational safety B561EN01.DOC
The workpieces are correctly positioned if, from the point of view of the operator, they are at least 50 mm in front of the bending line before the backgauge moves to the next stop position. This de-finition is applicable in combination with "Automatic Safety Travel Speed System" (ASV). If other backgauge traverse modes are used, other tool positions selected by the operator can also be correct, if these prevent collisions with the moving backgauge in a similar manner. If the machine is converted to robot loading, the machine's stan-dard protection systems are not sufficient. The machine including the robot must be additionally secured in compliance with the relevant safety regulations to prevent: Access from outside. Parts getting out from the inside. Any other form of use is regarded as other than intended. The manufacturer is not liable for any resulting damage. The owner bears the sole responsibility for risk in such cases. The machine guarantee is voided. Authorized application also includes complete adherence to the installation, operation, transport and maintenance conditions speci-fied by the manufacturer.

3.4 Measures to be taken by the manufacturer
The machine may only be operated with using appropriate safety devices used to secure the danger zone. The machine is equipped with the following safety measures for the danger zone: Optoelectronic safety devices: TRUMPF BendGuard or light
curtain. Operating modes "Foot operation" and "Two-foot operation"
(foot operation by two operators) with a rapid speed of 220 mm/s only in combination with an optoelectronic protective device.
Safety doors on the sides and a roller gate at the back to secure the danger zone, including special safety locking mechanisms.
Safety control system. Robot switch in switch cabinet. Manual adjustment of gauge finger without reaching into the
danger zone in the machine. EMERGENCY STOP and foot switch EMERGENCY-UP. Working at a rapid speed >10 mm/s is permitted only when an optoelectronic protective device is used.
The optoelectronic protective device must be available at the machine as a mandatory addition in the countries of the European Union and other countries with similar laws. TRUMPF offers the following optoelectronic protective devices: TRUMPF BendGuard. Light curtain. TRUMPF BendGuard enables work at rapid speed without im-pairing the safety of the operating personnel. To ensure this, the area underneath the upper tool is constantly monitored by two bands of three visible red laser beams, which move along with the machine. If the light beams are interrupted, the downward move-ment of the beam is stopped. The light curtain is an optoelectronic protective device and enables work at rapid speed without impairing the safety of the operating personnel.
The light curtain is attached in front of the beam and table and protects against obstacles from a length of 14 mm. If the light curtain is interrupted, the beam stops and moves to the upper dead center in order to avoid injuries. The movement of the beam then needs to be actively restarted.

In "foot operation", the beam of the machine can move downwards only at slow working speed (1-10 mm/s). In combination with the optoelectronic protective device, the beam can however move down (as far as the mute point) at rapid speed (220 mm/s). The optoelectronic protective device stops the descending movement of the beam if the operator reaches into the danger zone. When switching the operating mode from one to two
operators, the change of operating mode must be confirmed by both operators with the BEAM DOWN foot switch.
When switching the operating mode from two to one operator, the change of operating mode must be confirmed by both operators with the BEAM DOWN foot switch.
In the two-hand operation, the beam can move down (as far as the mute point) at rapid speed (>10 mm/s). After every bend, the approach to the next position of the backgauge must be initiated by pressing the foot switch. When operated by just one person, manual jog movement is
possible with the active foot switch BEAM DOWN. When operated by two persons, both operators need to
approve the manual jog movement by pressing the BEAM DOWN foot switch.
Note If only once switch is selected at the control system, then no stroke is triggered when the second foot switch is actuated.
The rear stop moves automatically to the next stop position at the end of the bending operation: If the target point of the rear back stop axis (X, R, Z) is within a
defined safety range, the relevant backgauge moves to the stop position in the Y direction at maximum speed. The danger of squeezing and crushing is avoided by a hinged rear stop finger. All other axes of the backgauge move with reduced speed.
If the start and target points are located outside the defined safety range, then the rear stop moves directly to the stop position with maximum speed.
Note If it is not possible to work with the "Automatic Safety Path System" (ASV), then a corresponding message will be displayed on the user interface. The "Manual increment switching" (MSC) method must be traversed in such cases.

The protective interlock devices (in particular the roller gate at the rear and the safety doors on the sides) for securing the danger zone of the machine are effective in all operating modes of the control system. If a sequestering protection device was previously opened, the operator must assure himself that there is nobody in the danger area secured by the protection device before restarting the machine. If the rear roller gate is opened during machine operation: The beam stops. All drive motors are stopped. All CNC-controlled axes are stopped. Opening the roller gate during operation of the machine is considered the same as pressing the EMERGENCY STOP. The machine cannot be restarted until all doors are closed.
If the side safety doors are opened during operation of the machine: All CNC-controlled axes are stopped. If one of the side safety doors is opened during operation: The beam can still move with reduced speed (max. 10 m/s)
after the BEAM DOWN or START foot switch is pressed. If both the side safety doors are opened during operation: The beam stops. All drive motors are stopped. All CNC-controlled axes are stopped.
Note The protective interlock devices (side safety doors, but also the covers of the hydraulic cylinder) are made partially of polymethyl-methacrylate (impact-resistant acrylic glass). This material can age as the result of environmental effects (become brittle). The owner must therefore check regularly that this material is still fulfilling its protective function.

The safety control system complies with the requirements of Category 4 of EN 954-1: A single error in the control system will not lead to the loss of
the safety function (single error security). If possible, the safety function recognizes an error either during
or before the next request from the safety function. An accumulation of errors should not normally lead to the loss
of the safety function. The safety functionalities thus remain operational when an error occurs. The error is recognized in time to prevent a loss of the safety functions. Safety is ensured by the following: Safety control system. Tested software modules. Use of double-channel outputs (e.g. for a high speed valve). The software version can be seen on the display of the safety control system.
Note The manufacturer accepts no responsibility for use of the safety control system software on other machines or for any improper use of the software. The control connection between the robot and the press is on the same plug in the switch cabinet as for operating station 1. The operating station must be out of the press area.
The robot switch in the switch cabinet has two settings: Setting 0: Beam travels without optoelectronic protective
device at reduced speed 10 mm/s. Setting 1: Robot operation.
The position of the robot switch is monitored: the beam moves to position 1 at rapid speed only if a robot is connected to a plug. If operating station 1 is connected, the beam only travels to position 1 at reduced speed even with the robot switch at setting 1.
During manual repositioning of the gauge fingers, they move to a safe tooling position for the operator in front of the tool level. The operator does not need to reach through the tool level.

2. Electrical supply
2.1 Power supply
Continuous undervoltage or overvoltage is not permitted. Greater voltage fluctuations endanger the problem-free operation of the machines and reduce their performance. Note The NEC applies only to Canada and the USA.
The machine and power distributor system must be equipped with a grounding line in accordance with NEC article 250, "Grounding".
For details on grounding power distributor systems and industrial plants, refer to the NEC standards or consult an electrician or the power station. Power supply lines in ungrounded power supply systems with delta connection are not fail-safe by nature. Delta power supply systems tend to generate transient overvoltage to ground. Delta power supply systems can result in increased voltages being applied to the connected devices. The control system or machine can no longer be operated reliably if a potential to ground occurs in the system. For this reason a grounded transformer must be installed in the star connection in delta power supply systems (see NEC article 450-5).

2.3 Network connection
TRUMPF provides the following interfaces for the network (e.g. a connection to a programming system) in the control cabinet of the machine: RJ 45 plugs for customers with shielded-twisted pair network
cabling. If several machines are to be connected to the network, a per-sonnel switch (network distributor) is necessary. The network distributor must be supplied with AC current by the customer, because the distributor must also function when the machine is switched off.
Note The same nominal voltage and frequency tolerances as those for the machine are applicable when using a personnel switch (network distributor) (see "Connected loads, fuse protection and frequency", p. 2-8).
Worldwide (outside the USA and Canada): 230 V with
grounded socket or in accordance with the receptive national standard.

3.1 Machine body
The FEM-designed machine body is an all-steel welded construction. It consists of two side elements, the press table and a connection support. The machine frame is particularly distinguished by: Consistently high level of accuracy. Large throat for a large bending space. Easy access to the tool holder. 3.2 Upper drive and hydraulic system
The beam is driven by a high-pressure internal gear pump via a self-ventilating proportional path hydraulic system. An integrated path measurement system which is in constant communication with the control system provides machine frame springback com-pensation, thereby guaranteeing the correct positioning of the beam during press brake bending.
This combination has the following advantages: The press force is immediately available. A high level of positioning accuracy allows for the precise
reproduction of bending angles, even for large-scale jobs. The machine is particularly quiet. Both hydraulic cylinder pairs on each side can be triggered separately. This allows a defined inclined position of the beam to be programmed. 3.3 Beam
The beam is suspended spherically in the machine frame. Its main features include: Consistently high level of accuracy. High level of bending rigidity.

3.4 Crowning
Crowning compensates for the bowing of the beam and press table in order to achieve a consistent and straight bend along the entire length. The following types of crowning are possible: Crowning shots with crowning blocks. Mechanical crowning (for TruBend 3120). Hydraulic crowning (for TruBend 3180). Crowning slots with crowning blocks
The crowning setting is automatic: there are two crowning slots located on both sides of the press table which cause the press table to apply more force on the outer sides than in the middle position, thus adjusting perfectly to the bowing of the beam.
1 1 1 Crowning slots
Press table with crowning slots The press table and crowning slots have been designed so that the correct crowning is always applied. The crowning can be activated as well as deactivated using a lever.

Mechanical crowning
In addition to standard crowning, the TruBend 3120 is also equipped with mechanical crowning that is at the center of the press table.
The press table (from a width of 3 m) is raised with the help of a wedge system. A uniform angle can be ensured for longer bends as well. Hydraulic crowning
In addition to standard crowning, the TruBend 3180 is also equipped with hydraulic crowning that is at the center of the press table. A uniform angle can be ensured for longer bends as well.
The press table (from a width of 4 m) is raised with the help of a hydraulic cylinder. The hydraulic cylinders (flat cylinders) are installed in a slotting in the machine frame.
The crowning value is calculated and displayed by the control system. The value can be manually adapted if required.

3.7 Backgauge
The backgauge supports the workpiece during bending. The following backgauge systems are possible: 2-axis backgauge. 4-axis backgauge (optional). 5-axis backguage (optional): 4-axes backgauge with an CNC-
controlled gauge finger (X5 axis). In case of a collision, the ideally hinged standard gauge fingers flip backwards. This prevents damage to bending parts and to the gauge finger. The gauge fingers can be moved 20 mm in front of the tool plane for repositioning. Because of this, the operator does not have to reach through the tool plane unassisted or using an auxiliary tool.

B561EN03.DOC 3BThe most important modules 3-17
2-axes backguage
The gauge depth (X axis) and the gauge height (R axis) are CNC-controlled. Improved workpiece quality is achieved by means of better control performance and RPM accuracy of the digital drive controllers for these axes. Additional features of the CNC backgauge system include: No tooling times for X and R axes, as the gauge height and
depth can be programmed freely at the control system. High positioning speed and wide traverse paths. This also
ensures minimum production time, even for large workpieces. Minimal handling time. Infinitely variable programming of X and R axes enables the
machining of complicated products and minimizes gauge tolerances.
4-axes backgauge (optional)
The 4-axis backgauge is an extension of the 2-axis backgauge. In addition to the CNC-controlled gauge depth (X axis) and gauge height (R axis), lateral adjustment of the gauge fingers (Z1/Z2 axes) is also CNC-controlled.
The gauge finger position is programmed directly into the control system, eliminating the need for manual gauge finger adjustment. 5-axes backgauge (optional)
The 5-axes backguage with a relative X-axis (X5 axis) is a configuration stage of the 4-axes backgauge. One of the two gauge fingers can be moved in the X direction by 80 mm in an NC-controlled manner.
The X5 axis can be programmed in the control system.
