Maintenance And Checking - Pilous ARG 220 D Instruction Manual

Electrical Installation Faults -
FU 2 or FU 3 fuse s burn out repeatedly.
The rectifier diode of one of the magnets is probably broken.
Disconnect the terminal wires 76,79,82,86,88,89 and 90 on the X 1 terminal board, replace the burn-out fuse and switch on the
machine. If the fuse burns out again, the short circuit is caused elsewhere. Check the switchboard or the limit switch for a short-
circuited earth conductor. Gradually connect the conductors disconnected from the terminals using the following procedure: connect
one conductor and switch on the hydraulic system. If the fuse does not burn out, connect the next conductor, as soon as the
conductor connected burns out the fuse, replace the respective magnet on the hydraulic unit.
The moving vice cannot be moved in manual mode
The switch must be in the Manual Mode position. The band saw head must be in the upper position on the BP3 limit switch. The stop
must not be in zero position; it is necessary to set the required measure on a hand-operated counter or remove the stop by PLC. Both
vices must be unclamped.
The H1 green signal light does not light up when the master switch is switched on
Check the Total Stop SB 1, the BP 2 limit switch of the band saw head and the BP 1 saw blade tensioning. Check the input voltage on
the X1 supply terminal board with L1, L2, L3, N, Pe terminals, and/or the TR 1 transformer output voltage on 0 V and 24 V terminals.
The machine does not measure the length correctly
Make sure that no wire in the 96,97,67,95 terminals of the X1 terminal board has become loose. Make sure that the coupling between
the IRC 1 sensor and the measuring screw is tight. If everything is all right, replace the IRC 1 sensor.
The stop does not stop at the required measure and the frequency converter signals an error at the end of
screw
Switch off and on the hydraulic system of the machine. The error code is displayed on the frequency converter. Press the STOP
RESET button on the frequency converter; after a while 0.0 will be displayed. Switch over the switch to automatic mode; the stop
must start moving towards the zero position. After that, proceed in conformity with item "The machine does not measure the length
correctly".
10. Machine Maintenance and Checking
Caution - danger of injury!
Carry out maintenance only when the master switch is off or the machine isolated from supply.
In order that the functionality of the machine and its components may be maintained, it is unconditionally necessary to carry out the
maintenance of the machine, which includes the following operations: check and adjustment of band saw guide heads and limit
angles • machine cleaning • metal chips removal • removing metal chips from the internal part of the band saw head • coolant
exchange • regular checking of quantity and cleanliness of oil in the hydraulic system • lubrication of sliding surfaces and mounting •
checking of supply lines for damage • vice check • screw connection check • limit switch check.
Checking of Protective Enclosures
Check the protective enclosures of the machine for any damages and failures before starting everyday work.
Feed Line Checking
Make a regular check of the following items at least once a week: power line integrity • intactness of line connections and pull
relief. Inspections and checks of electric appliances are subject to valid legal regulations of the respective country.
Machine Cleaning
Clean the machine thoroughly at regular intervals (always after the shift or during the shift, if required). Use appropriate cleaning
agents. Do not use solvents (e.g. nitrosolvents). do not use compressed air for cleaning the machine! Otherwise the fine chips and
impurities will penetrate under the sliding elements. Keep all induction sensors clean! (see figure).
Removal / Disposal of Metal Chips
Observe the instructions and recommendations concerning safe disposal of waste produced
during operation.
Correct cutting angles will be achieved when the bearing surfaces for the workpiece and the surfaces of gripping jaws are free from
metal chips and other impurities.
