4. EMERGENCY STOP AND RESET

In dangerous situations for the operator’s health or if there is risk of breakage of anymechanical component of the machine, press immediately the emergency mushroom headbutton.Such operation interrupts immediately the electrical power supply to the machine and anymotion in course.

When danger has ceased, reset the mushroom head button by turning it in the samedirection of the arrow, in order to reset the normal working conditions of the machine andthen press reset button R.



5. START UP OF MACHINE

The plug of the main power cable can be inserted, after checking the exactcorrespondence between the voltage of the machine and the line voltage.Select 1 (ON) on the main switch near the door of the electrical cabinet for electrical supplyof the machine (each time a working cycle ends, switch off the machine selecting 0 (OFF)on the main switch).Check that the mushroom head emergency button has not been pressed. In case theemergency button is pressed, turn it in the opposite sense to the direction of the arrowuntil resetting it.Press button R ( machine reset ) to supply power to the electrical devices of the machine.

6. OPERATION MODE SELECTION

You can select the operation mode of the machine (press or expander / reducer) bypressing ENTER button for 4 seconds.

The mode selected is indicated by the first letter on the left side of the display (Fig. 2 , 3)

Fig.3 – Expander/reducer mode



The press mode selection allows only the horizontal cylinder to move. If expander/reducermode is selected, vice opening / closure is allowed too.

7. TOOLING SELECTION

It is possible to effect a working cycle in “assist “ mode or in “manual” mode.The “assist” mode allows a complete working cycle according to the selected machineoperation mode ( press or expander/reducer ) by simply pressing at the same time the twoSTART 1 e START 2 buttons, placed on the side of the control panel. (ref. par. 2).The working cycle can be interrupted by releasing one of the two buttons.

The manual operation mode allows the individual movement of each function with fullrespect of the safety standards.

1. TOOL FORWARD: press forward button + START 2 (before FORWARD BUTTON)

2. TOOL RETURN: press return button + START 1 (before RETURN BUTTON)

3. VICE CLOSURE: press close button + START 1 + START 2 (before CLOSE BUTTON)

4. VICE OPENING: press open button + START 1 + START 2 (before OPEN BUTTON)

NB:A complete vice opening and closure under manual mode, can require moreoperations.

NOTE: Use cylinder tool in “manual” operation mode only for position referencesduring programming and not for job cycles.

WARNING: FOR SAFETY REASONS, keep the protection cover closed duringexpanding / reducing operation mode. If protection casing is open duringexpanding / reducing mode, vice is unabled to open and / or close.

8. PROGRAMME SELECTION

Once you have set the operating mode of the machine (press or expander/reducer), followthese procedures to select one of the 8 working programs:

Press once menu / esc button in order to evidence the program number whichyou need to recall or modify for a new working cycle (Fig. 4):

With forward and return buttons set the required program number andpress enter to confirm.

Fig.4 – Working program selction.



9. HOW TO SET UP PARAMETERS

Before starting a work cycle, it is necessary to set the work parameters , the “zeroreference” and “material reference” with the tool.

The zero reference is the starting point from which the tool starts and stops at the end ofa job cycle.

The material zero is the point in which the tool comes into contact with the material .

The penetration level is the distance along which the tool penetrates into the material.

The machine is pre-set by the factory in order that tool moves from “zero reference” to“material zero” with high speed, and in order to penetrate into the material with low speedaccording to the programmed level. When the penetration level is reached, the tool goesback to zero reference with high speed.

Select working programme and bring the cylinder to the desired position

as zero reference. Such position is stored by pressing the buttons +(press first RETURN BUTTON).The flashing display confirms position memorisation.

The Material zero point is effected by bringing the tool to the required position and + by

pressing buttons + (FORWARD BUTTON FIRST) for memorisation.

The figure on the right hand of the display should show “000.0” to confirm memorisationhas taken place.

In order to set penetration level, press twice menu / esc button until thefollowing is displayed as evidenced in fig. 5:

zero reference Material zero Penetration level

Penetration level Fig.5 – Penetration level selection.



By using + buttons set the desired value and confirm bypressing ENTER.

Carry out a working cycle with no material to verify that set parameters are correct. Thepenetration level must always be negative.The first value on the right side of the display (Fig. 6) indicates the current position of thetool in relation to zero reference.

10. WORKING SPEED SELECTION

By default the machine is set in order to carry out the working cycle with low speed duringpenetration/ folding phase.However, it is possible to vary such set up so as that tool can move with high speed evenduring penetration/folding phase. Therefore it is important to press the two

buttons +

The high or low speed set up is displayed by the message FAST or SLOW as showed in fig.7 and 8:

Low speedFig.8 – Low speed selection



11. HOW TO ZERO JOB CYCLE COUNTER

The machine is provided with a job cycle counter indicating the number of work cycleseffected.The registered values are displayed on the right side at the end of each cycle (fig.9).

When a new working cycle is started it is possible to zerothe counter by pressing

12. HOW TO CHANGE HOLDING JAWS

In order to change the type of vice jaws, proceed in the following manner:

1. Close vice2. Select CHANGE for the holding jaws through position ON and extract key for extra

safety.3. Open vice until it is in position and no motion is possible.4. Change vice jaws .5. Insert key into selector and set OFF position.6. Start working cycle.

When holding jaws are changed, a particular configuration of the electrical circuit blockstool movement and allows the vice to move until change position is reached. After suchchange, any motion of the machine is not enabled until CHANGE selector is set on OFFposition.

13. PRESSURE REGULATION

It is possible to regulate the tool and vice pressure through the pressure regulators of themachine.

On the left side of the electrical panel there is a pressure regulator for the cylinder tool. Onthe right side there is the pressure regulator for the vice.

It is possible to regulate the pressure regulations through the appropriate knobs tooptimise work process.
