18. Removal of the device and re-installation after repair
If DSP LASER presents a defect or a malfunction, and then must be disconnected from the
machine to be repaired, act as described below (this procedure allows avoiding the
disconnection of the cables, limiting the operation only to the unassembly of the component
of the device to repair):
•
Disconnect the machine from the power grid; if present, AL module has been correctly
inserted downstream the main switch (as described in the procedure of electrical
connection), the device power supply will be automatically cut.
If this has not been made, disconnect the AL module; moreover, at the re-installation,
the connection must be modified according to what pointed out in the relevant
chapter.
•
Disconnect mechanically TX and RX from the machine.
•
Remove the rear cover, as in Fig.18.1, both from TX and from RX, unscrewing the
four screws.
•
Extract the 4-pole female connector from the male one welded on TX, those with 12
and 3 poles from the corresponding male ones welded on RX.
TX and RX are separated from the machine.
Fig.18.1 Removal of the rear cover
•
If present, disconnect electrically the AL module from the machine extracting the
female connectors from the corresponding male ones welded on the printed circuit of
AL.
•
If present, disconnect mechanically the AL module from the DIN rail where it is
housed, removing the anchoring of the rail of the spring stop, with a screwdriver of
proper size.
•
Send the three parts to the Manufacturer, according to what described in the chapter
Warranty, pointing out the detected defect.
•
Before reconnecting the parts returned from the repair, be sure the machine is
disconnected from the power supply.
•
Reconnect mechanically TX and RX to their own brackets and, if present, AL module
to the DIN rail.
•
Insert the female connectors of TX, RX and, if present, AL module into the
corresponding male connectors.
•
Put the rear cover to its place and, as from Fig.18.1, both on TX and RX, screw again
the four screws.
•
Execute again the commissioning and test procedures described in the relevant chp.
