7.6. Maintenance, inspection and repair
All maintenance and repair works have to be basically performed with the
machine in off position.
During this the machine has to be secured against unauthorized switching on.
Prescribed maintenance and inspection works should be performed in time.
The DVS gives the advice of inspection works after 1 year.
For machines with a specially high usage percentage the testing cycle should be
shortened.
The works should be performed at the WIDOS GmbH company or by an
authorized partner.
•
The operating staff has to be informed before the starting of the maintenance works.
•
Check the tightness of all screwed connections and tighten again if need be.
•
Check the function of the safety devices after completion of the maintenance works.
Check especially insulation and tension resistance and protective cables resistance.
7.7. Saving the Welding Data
The battery buffer for the CNC-memory (RAM) goes empty.
Without current connection, the batteries necessary for the storage of the
welding data work for about 1 month.
Remedy
: connect the machine to power, switch it on and leave it switched on
for 24 hours in order to completely load the batteries.
Please make sure that before a longer non operation period of the machine the
welding data are read out so that they can not get lost.
7.8. Data Interface Connection
Use only WICON data transmission cables for the serial data interface (9-pins) !
Common available cables
may not
be connected because they may cause
damages on the connected laptop or on the CNC unit!
At the printer connection (25-pins) a common available parallel printer cable can
be connected.
In order to avoid dirtiness in the sockets, the interfaces should be covered if they
are out of usage.
