6. INSTALLING AND CONNECTING THE MACHINE One must exercise extra attention and thoughtfulness, when drilling with the BP93p machine. Pay particular attention to the fire protection of both the machine and the room in which it operates, as sparks are produced that may come into direct contact with the dielectric fluid.

to period examination performed by a Sanitary and Epidemiological Station, in order to “ ” measure the level of electromagnetic field emission and define hazard areas in a given room. Attention!!! The warning signs compliant with PN-74/T-06260 must be located next to the entrance to the room where the machine operates.

Carry out repair work or other work that may lead to damaging the tank or igniting the dielectric fluid; i) Modify electric or hydraulic systems, without prior consulting with ZAPbp. Recommendations: a) Use a separate, well-ventilated room.
Page 10
f) Use a blowing system that eliminates vapours from above the tank, or a spot extractor – vapours must be directed outside the working room. The extracting system must be efficient, in order to eliminate any condensation of the dielectric fluid in conduits, or possible isolated water pools, as that can pose a fire hazard.

2 Manual Working Mode Initial notes: The machine will only work within the positive quadrant of the global co-ordinate system that is also referred to as a physical co-ordinate system. If the user attempts to travel toward negative physical coordinates, the system will generate an appropriate error message.
5) Activate/Deactivate the Ignore Short Circuit function by pressing the [IZR] button (activate this functions, if it is necessary to ignore the contact between the working bit of the machine with the table, during travelling, e.g.resulting from measuring the location of a workpiece on the table, using a sensor).
Screen: Course of action: 1) Select a specific character and the axis for which we intend to declare target coordinates, by pressing an appropriate key included in the directional keypad (see Fig. 1). The entry window dedicated to the selected axis of travel will be displayed. 2) Enter the required value of coordinate, using the numeric keypad ([DEL] –...
The machine has undergone repairs that required the disconnecting of the generator from the mechanical section of the machine. Failing to perform the Home function, once any of the afore-mentioned conditions has occurred, may “ ” result in an incorrect operation of the travel to a characteristic point function and locking of manual travels toward the selected direction.
Stopping the process: Travel has been paused by pressing the [STOP] key. Critical ruler error: The ruler does not report that it has completed travel, although the motor responsible for movement along a given axis has received a message about completion of travel. This error occurs, when: There is a motor malfunction;...
2) Enter the required value of coordinate, using the numeric keypad ([DEL] – Deletes the entered character; [ESC] – Cancels the option of entering a value). 3) Accept the entered value, by pressing [ENT]. 4) Declaration of coordinate for another axis – go back to item 1. 5) Confirm the declared coordinates, by pressing [F1] “Accept”.
Screen: Course of action: 1) Select a specific character and the axis for which we intend to declare new operator’s coordinates, by pressing an appropriate key included in the directional keypad (see Fig. 1).

Attention!!! You must remember that the automatic alignment on mandrel requires setting the direction and turning point of alignment in such a way that that electrode comes into contact with a workpiece, when it is moving toward that particular direction. The process of alignment is cancelled, if the electrode has moved by 50mm, after alignment was started, and there is no contact with the workpiece.
